判断APP是否是最新版本 和 获取 APP 版本号

<写在一个方法中>

- (void)VersionUpdate{

    

    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];

    CFShow(infoDictionary);

    NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    [manager GET:@"https://itunes.apple.com/cn/lookup?id=868722244" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

        

        NSDictionary *dic = (NSDictionary *)responseObject;

        NSArray *arr = [dic objectForKey:@"results"];

        NSString *app_NewVersion = [[arr objectAtIndex:0] objectForKey:@"version"];

    //判断 然后 弹出    AlertView

        if (![app_Version isEqualToString:app_NewVersion]) {

            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"温馨提示" message:@"当前版本不是最新版本,是否更新" delegate:self cancelButtonTitle:@"下次更新" otherButtonTitles:@"更新", nil];

            [alert show];

            [alert release];

        }

        

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        

    }];
