iOS开发-实现获取下载主题配置更切换主题主要是通过请求服务端配置的主题配置、下载主题、解压保存到本地。通知界面获取对应的图片及颜色等。
比如新年主题风格常见的背景显示红色氛围图片、tabbar显示新年风格的按钮样式、导航条显示红色样式等。
一、主题Json对应的model
这里使用JsonModel将主题转成model
model代码如下
SDAppThemeConfigViewModel.h
#import Foundation/Foundation.h
#import UIKit/UIKit.h/**Navigation主题样式*/
interface SDAppThemeConfigNavViewModel : NSObjectproperty (nonatomic, strong) NSString *backgroundColor;
property (nonatomic, strong) NSString *backgroundImage;property (nonatomic, strong) UIImage *t_backgroundImage;property (nonatomic, strong) NSString *btnImageColor;
property (nonatomic, strong) NSString *btnTitleColor;
property (nonatomic, strong) NSString *navTitleColor;property (nonatomic, strong) NSString *showLine;
property (nonatomic, strong) NSString *lineColor;end/**单个tab按钮样式*/
interface SDAppThemeConfigTabItemViewModel : NSObjectproperty (nonatomic, strong) NSString *title;
property (nonatomic, strong) NSString *titleColor;
property (nonatomic, strong) NSString *selectedTitleColor;
property (nonatomic, strong) NSString *icon;
property (nonatomic, strong) NSString *selectedIcon;property (nonatomic, strong) UIImage *t_icon;
property (nonatomic, strong) UIImage *t_selectedIcon;end/**tabbar样式*/
interface SDAppThemeConfigTabViewModel : NSObjectproperty (nonatomic, strong) NSString *backgroundColor;
property (nonatomic, strong) NSString *backgroundImage;
property (nonatomic, strong) NSString *showLine;
property (nonatomic, strong) NSString *lineColor;
property (nonatomic, strong) NSString *badgeBgColor;property (nonatomic, strong) UIImage *t_backgroundImage;property (nonatomic, strong) SDAppThemeConfigTabItemViewModel *lianlian;
property (nonatomic, strong) SDAppThemeConfigTabItemViewModel *guangguang;
property (nonatomic, strong) SDAppThemeConfigTabItemViewModel *message;
property (nonatomic, strong) SDAppThemeConfigTabItemViewModel *shop;
property (nonatomic, strong) SDAppThemeConfigTabItemViewModel *mine;end/**将本地的主题config.json转成viewmodel*/
interface SDAppThemeConfigViewModel : NSObjectproperty (nonatomic, strong) NSString *globalColor;
property (nonatomic, strong) NSString *globalImage;
property (nonatomic, strong) SDAppThemeConfigNavViewModel *navigation;
property (nonatomic, strong) SDAppThemeConfigTabViewModel *tabbar;property (nonatomic, strong) UIImage *t_globalImage; (SDAppThemeConfigViewModel *)themeViewModel:(NSString *)themeJson; (SDAppThemeConfigViewModel *)defautThemeViewModel;endSDAppThemeConfigViewModel.m
#import SDAppThemeConfigViewModel.h
#import NSObjectYYModel.h/**Navigation主题样式*/
implementation SDAppThemeConfigNavViewModelend/**单个tab按钮样式*/
implementation SDAppThemeConfigTabItemViewModelend/**tabbar样式*/
implementation SDAppThemeConfigTabViewModelend/**将本地的主题config.json转成viewmodel*/
implementation SDAppThemeConfigViewModel (SDAppThemeConfigViewModel *)themeViewModel:(NSString *)themeJson {return [SDAppThemeConfigViewModel modelWithJSON:themeJson];
} (SDAppThemeConfigViewModel *)defautThemeViewModel {SDAppThemeConfigViewModel *viewModel [[SDAppThemeConfigViewModel alloc] init];SDAppThemeConfigNavViewModel *navConfigViewModel [[SDAppThemeConfigNavViewModel alloc] init];navConfigViewModel.backgroundColor 171013;navConfigViewModel.btnImageColor ffffff;navConfigViewModel.btnTitleColor ffffff;navConfigViewModel.navTitleColor ffffff;viewModel.navigation navConfigViewModel;return viewModel;
}end二、实现下载解压主题
2.1 AFNetworking下载
下载使用的是AFNetworking下载功能。AFNetworking是一个轻量级的iOS网络通信类库。
下载代码
#pragma mark - Http download
/**请求下载param aUrl aurlparam aSavePath aSavePathparam aFileName aFileNameparam aTag aTagparam downloadprogress downloadprogressparam success successparam failure failure*/
- (void)downloadFileURL:(NSString *)aUrlsavePath:(NSString *)aSavePathfileName:(NSString *)aFileNametag:(NSInteger)aTagdownloadProgress:(void(^)(CGFloat progress))downloadprogresssuccess:(void(^)(NSURLResponse *response,NSString *filePath))successfailure:(void(^)(HttpError * e))failure {NSFileManager *fileManger [NSFileManager defaultManager];if ([fileManger fileExistsAtPath:[aSavePath stringByAppendingPathComponent:aFileName]]) {//文件存在return;}//2.确定请求的URL地址NSString *requestUrl [self requestUrlWithPath:aUrl clientType:HttpClientTypeWithOut];NSMutableURLRequest *request [self.httpManager.requestSerializer requestWithMethod:GET URLString:requestUrl parameters:nil error:nil];__block NSURLSessionDownloadTask *downloadTask nil;downloadTask [self.httpManager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {dispatch_async(dispatch_get_main_queue(), ^{downloadprogress(1.0 * downloadProgress.completedUnitCount / downloadProgress.totalUnitCount);});} destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {return [NSURL fileURLWithPath:aSavePath];} completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) {if(error nil) {success(response,[filePath path]);} else {//下载失败NSHTTPURLResponse *httpResponse (NSHTTPURLResponse *)response;HttpError *e [self httpRequestFailure:httpResponse error:error];failure(e);}}];[downloadTask resume];
}2.2 判断主题版本是否已经下载
在获取主题版本时候需要判断主题是否存在如果存在则直接获取保存的地址。不存在下载解压当前版本的主题包。
//判断当前主题版本号下是否存在资源文件夹BOOL curThemeExist [self hasAppThemeVersion:themeModel.curVersion];if (!curThemeExist) {//如果不存在重新下载解压__block NSString *saveZipPath [self saveThemeTargetBasePath:themeModel.curVersion];__block NSString *themeUnZipPath [self saveThemeDirBasePath:themeModel.curVersion];__block NSString *curDownloadurl themeModel.curDownloadurl;//下载成功NSString *afileName [[NSURL URLWithString:curDownloadurl] lastPathComponent];__block NSString *afilePath [NSString pathWithComponents:[saveZipPath, afileName]];[[INHttpClientUtil sharedInstance] downloadFileURL:curDownloadurl savePath:afilePath fileName:afilePath tag:[afilePath hash] downloadProgress:^(CGFloat progress) {} success:^(NSURLResponse *response, NSString *filePath) {//下载成功NSString *fileName [[NSURL URLWithString:curDownloadurl] lastPathComponent];NSString *selFilePath [NSString pathWithComponents:[saveZipPath, fileName]];//准备执行解压方法[self onFileSelected:selFilePath unZipPath:themeUnZipPath];} failure:^(HttpError *e) {NSLog(failure request :%,e);}];} else {//如果存在直接显示__block NSString *saveZipPath [self saveThemeTargetBasePath:themeModel.curVersion];__block NSString *themeUnZipPath [self saveThemeDirBasePath:themeModel.curVersion];__block NSString *curDownloadurl themeModel.curDownloadurl;//下载成功NSString *fileName [[NSURL URLWithString:curDownloadurl] lastPathComponent];NSString *filePath [NSString pathWithComponents:[saveZipPath, fileName]];//准备执行解压方法[self unzipCompltion:themeUnZipPath];}2.2 解压zip主题包
将下载的主题包解压zip包进行解压。
// 解压
- (void)releaseZipFilesWithUnzipFileAtPath:(NSString *)zipPath destination:(NSString *)unzipPath {NSError *error;// 如果解压成功if ([SSZipArchive unzipFileAtPath:zipPath toDestination:unzipPath overwrite:YES password:nil error:error delegate:self]) {// 存储主题的色调[self unzipCompltion:unzipPath];} else {NSLog(%,error);}
}解压完成后得到解压的目录。
2.3 获取到解压的目录地址将配置的json文件转成对应的model
获取到解压的目录地址将配置的json文件转成对应的model
/**调用解压文件param unzipPath 获取地址*/
- (void)unzipCompltion:(NSString *)unzipPath {// 存储主题的色调// 已经存储主题tabbar图片、navigationbar图片、配置文件等等资源NSArray *folders [[NSFileManager defaultManager] contentsOfDirectoryAtPath:unzipPath error:NULL];NSString *selectedFilePath unzipPath;NSString *aPath [folders lastObject];NSString *fullPath [unzipPath stringByAppendingPathComponent:aPath];selectedFilePath fullPath;NSString *configPath [NSString stringWithFormat:%/config.json,selectedFilePath];NSFileHandle *fh [NSFileHandle fileHandleForReadingAtPath:configPath];NSData *data [fh readDataToEndOfFile];NSString *jsonStr [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];NSMutableDictionary *dict [[NSMutableDictionary alloc] initWithDictionary:[SDJsonUtil dictionaryWithJsonString:jsonStr]];NSLog(theme config.json:%,dict);SDAppThemeConfigViewModel *themeViewModel [SDAppThemeConfigViewModel themeViewModel:jsonStr];themeViewModel.t_globalImage [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.globalImage];themeViewModel.navigation.t_backgroundImage [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.navigation.backgroundImage];themeViewModel.tabbar.t_backgroundImage [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.backgroundImage];themeViewModel.tabbar.lianlian.t_icon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.lianlian.icon];themeViewModel.tabbar.lianlian.t_selectedIcon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.lianlian.selectedIcon];themeViewModel.tabbar.guangguang.t_icon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.guangguang.icon];themeViewModel.tabbar.guangguang.t_selectedIcon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.guangguang.selectedIcon];themeViewModel.tabbar.message.t_icon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.message.icon];themeViewModel.tabbar.message.t_selectedIcon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.message.selectedIcon];themeViewModel.tabbar.mine.t_icon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.mine.icon];themeViewModel.tabbar.mine.t_selectedIcon [self imageWithDocumentoryName:[NSString stringWithFormat:%,selectedFilePath] imageName:themeViewModel.tabbar.mine.selectedIcon];//配置全局主题[SDAppThemeManager shareInstance].configViewModel themeViewModel;[[NSNotificationCenter defaultCenter] postNotificationName:K_APP_THEME_CHANGED object:nil userInfo:nil];
}之后通知界面切换对应的图片及风格图。
2.4 界面添加通知Observer
界面接收到通知后更新到对应的图片及颜色。 我这里是就写一个切换Tabbar新年主题风格图片。
[[NSNotificationCenter defaultCenter] addObserver:self selector:selector(systemAppThemeChanged:) name:K_APP_THEME_CHANGED object:nil];切换Tabbar新年主题风格图片
- (void)updateThemeConfig {//主题可以更改tabbar样式SDAppThemeConfigViewModel *themeConfigViewModel [SDAppThemeManager shareInstance].configViewModel;UIImage *backgroundImage;if (themeConfigViewModel.tabbar.t_backgroundImage) {backgroundImage themeConfigViewModel.tabbar.t_backgroundImage;} else {NSString *bgColor themeConfigViewModel.tabbar.backgroundColor;backgroundImage [UIImage imageWithColor:[UIColor colorWithHexString:bgColor] size:CGSizeMake(20.0, 20.0)];backgroundImage [backgroundImage stretchableImageWithLeftCapWidth:backgroundImage.leftCapWidth*0.5 topCapHeight:backgroundImage.topCapHeight*0.5];}self.sdTabbar.bgroundImage backgroundImage;NSString *showLine themeConfigViewModel.tabbar.showLine;self.sdTabbar.showLine [showLine boolValue];self.sdTabbar.lineColor [UIColor colorWithHexString:themeConfigViewModel.tabbar.lineColor];UIColor *badgeBGColor [UIColor colorWithHexString:themeConfigViewModel.tabbar.badgeBgColor];SDTabbarItem *homeItem [self themeTabbarItem:themeConfigViewModel.tabbar.lianlian];homeItem.identifier home;homeItem.badgeColor badgeBGColor;SDTabbarItem *addressbookItem [self themeTabbarItem:themeConfigViewModel.tabbar.message];addressbookItem.identifier addressbook;addressbookItem.badgeColor badgeBGColor;SDTabbarItem *discoveryItem [self themeTabbarItem:themeConfigViewModel.tabbar.guangguang];discoveryItem.identifier discovery;discoveryItem.badgeColor badgeBGColor;SDTabbarItem *mineItem [self themeTabbarItem:themeConfigViewModel.tabbar.mine];mineItem.identifier mine;mineItem.badgeColor badgeBGColor;[self.sdTabbar updateTabbarStyle:homeItem];[self.sdTabbar updateTabbarStyle:addressbookItem];[self.sdTabbar updateTabbarStyle:discoveryItem];[self.sdTabbar updateTabbarStyle:mineItem];
}- (void)systemAppThemeChanged:(NSNotification *)notification {[self updateThemeConfig];
}- (SDTabbarItem *)themeTabbarItem:(SDAppThemeConfigTabItemViewModel *)itemViewModel {SDTabbarItem *tabbarItem [[SDTabbarItem alloc] init];tabbarItem.title itemViewModel.title;tabbarItem.titleColor [UIColor colorWithHexString:itemViewModel.titleColor];tabbarItem.selectedTitleColor [UIColor colorWithHexString:itemViewModel.selectedTitleColor];tabbarItem.image itemViewModel.t_icon;tabbarItem.selectedImage itemViewModel.t_selectedIcon;return tabbarItem;
}tabbar的按钮更新根据对应的identifier切换到对应的图片及颜色配置。
/**更新tabbar样式param tabbarItem item*/
- (void)updateTabbarStyle:(SDTabbarItem *)tabbarItem {for (UIView *subView in self.subviews) {if ([subView isKindOfClass:[SDTabbarButton class]]) {SDTabbarButton *tabbarButton (SDTabbarButton *)subView;SDTabbarItem *item tabbarButton.tabbarItem;if (tabbarItem.identifier [tabbarItem.identifier isEqualToString:item.identifier]) {//更新tabbar[item copyClone:tabbarItem];tabbarButton.tabbarItem item;break;}}}
}三、将model序列化存储到本地目录
将主题数据序列号存储到本地目录方便下次打开APP进行获取。
SDAppThemeConfigDbManager.h
#import Foundation/Foundation.h
#import SDAppThemeManager.hinterface SDAppThemeConfigDbManager : NSObject (id)shareInstance;- (SDAppThemeViewModel *)getAppThemeViewModelFromDb;- (void)saveAppThemeViewModelToDb:(SDAppThemeViewModel *)info;endSDAppThemeConfigDbManager.m
#import SDAppThemeConfigDbManager.hstatic NSString *appThemeConfigPath sdAppThemeConfigPath;
static SDAppThemeConfigDbManager *instance nil;implementation SDAppThemeConfigDbManager (id)shareInstance
{static dispatch_once_t predicate;dispatch_once(predicate,^{instance [[self alloc] init];});return instance;
}- (NSString *)getAppThemeConfigPath
{NSArray *paths NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);NSString *documentPath [paths objectAtIndex:0];NSString *path [documentPath stringByAppendingPathComponent:appThemeConfigPath];return path;
}- (SDAppThemeViewModel *)getAppThemeViewModelFromDb {NSString *dataFile [self getAppThemeConfigPath];try {SDAppThemeViewModel *viewModel [NSKeyedUnarchiver unarchiveObjectWithFile:dataFile];if (viewModel) {return viewModel;}} catch (NSException *e) {}return nil;
}- (void)saveAppThemeViewModelToDb:(SDAppThemeViewModel *)info {NSData *data [NSKeyedArchiver archivedDataWithRootObject:info];NSString *dataFile [self getAppThemeConfigPath];BOOL isSave [data writeToFile:dataFile atomically:YES];if (isSave) {NSLog(存储成功);} else {NSLog(存储失败);}
}end四、完整实现代码
