- (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];
