注意:苹果官方是不允许app具有检查更新提示!

//直接跳转到AppStore

- (void)setUpAppUpdate {
    [ServerData queryGetURL:@{@"URL":@"http://itunes.apple.com/search", @"dic":@{@"term":@"POPOLOOK", @"entity":@"software"}} successBlock:^(NSDictionary *dataDic) {
        NSLog(@"-=-=-=-=-=-=-=-==-=-==APP检查更新:%@", dataDic);
        } failBlock:^(NSString *errorMsg) {
        //使用本地
    }];
}

//在应用内打开AppStore界面
- (void)setUpAppUpdate2 {
