app版本版本的更新的问题

#pragma mark - 获取 AppStore 版本号

+ (void)fetchAppStoreVersion:(void (^)(NSString *appStoreVersion))version {

NSString *urlString = @"http://itunes.apple.com/lookup?id=1123497532";

[LBHTTPTool postDataSourceWithUrl:urlString params:nil contentType:@"text/javascript" success:^(id responseObject) {

NSString *appStoreVersion = [responseObject[@"results"] lastObject][@"version"];

version(appStoreVersion);

} failure:^(NSError *error) {

NSLog(@"%@", error);

}];

}

#pragma mark - 获取当前安装版本号

+ (NSString *)fetchCurrentInstalledVersion {

return [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

}

#pragma mark - 跳转到 AppStore 下载

+ (void)skipToAppStore {

NSString *urlString = @"itms-apps://itunes.apple.com/app/id1123497532";

id 为应用的appid

NSURL *url = [NSURL URLWithString:urlString];

[[UIApplication sharedApplication] openURL:url];

}
