IOS版本更新代码

-(void)checkAppUpdate
{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];

    NSString *nowVersion = [infoDict objectForKey:@"CFBundleVersion"];  
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?id=%@", kStoreAppId]];  

    NSString * file =  [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];  
    NSLog(@"%@",file);  
    dispatch_async(dispatch_get_main_queue(), ^{  
        NSData *data = [file dataUsingEncoding:NSUTF8StringEncoding];  
        NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];  
        if(((NSArray*)dic[@"results"]).count>0)  
        {  

            NSString *newVersion = [NSString stringWithFormat:@"%@",dic[@"results"][0][@"version"]];  

            NSString *nowVersion2 = [nowVersion stringByReplacingOccurrencesOfString:@"." withString:@""];  
            NSString *newVersion2 = [newVersion stringByReplacingOccurrencesOfString:@"." withString:@""];  

            if([newVersion2 intValue]>[nowVersion2 intValue])  
            {  
                NSString *newMsg = [NSString stringWithFormat:@"%@",dic[@"results"][0][@"releaseNotes"]];  
                NSString *newstr = [NSString stringWithFormat:@"有新版V%@",newVersion];  
                UIAlertView *alert = [[UIAlertView alloc] initWithTitle:newstr message:newMsg delegate:self cancelButtonTitle:@"取消"otherButtonTitles:@"更新",nil];  
                [alert show];  
            }  
        }  
    });  
});  

}

  • (void)alertView:(UIAlertView)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
    {
    if(buttonIndex==1)
    {
    // 此处加入应用在app store的地址,方便用户去更新,一种实现方式如下:
    NSURL
    url = [NSURL URLWithString:[NSString stringWithFormat:@"https://itunes.apple.com/us/app/id%@?ls=1&mt=8", kStoreAppId]];
    [[UIApplication sharedApplication] openURL:url];
    }
    }
