检查新版本 更新  第一种方法

  //检查新版本 更新

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, ), ^{
// 耗时的操作 //获取本地版本号
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
NSString *version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
NSString *build = [infoDictionary objectForKey:@"CFBundleVersion"];
NSString *nowVersion = [NSString stringWithFormat:@"%@.%@", version, build]; //获取appStore网络版本号
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?id=%@", @""]];
NSString * file = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil]; NSRange substr = [file rangeOfString:@"\"version\":\""];
NSRange range1 = NSMakeRange(substr.location+substr.length,);
// NSRange substr2 =[file rangeOfString:@"\"" options:nil range:range1];
NSRange substr2 = [file rangeOfString:@"\"" options:NSCaseInsensitiveSearch range:range1];
NSRange range2 = NSMakeRange(substr.location+substr.length, substr2.location-substr.location-substr.length);
NSString *appStoreVersion =[file substringWithRange:range2]; dispatch_async(dispatch_get_main_queue(), ^{
// 更新界面 //如果不一样去更新
if(![nowVersion isEqualToString:appStoreVersion])
{ [self showAlert]; } });
}); /**
* 检查新版本更新
*/
-(void)showAlert
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"有新的版本啦~~" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"前去更新",nil];
[alert show]; } - (void)alertView:(UIAlertView*)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==)
{
// 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", @""]];
[[UIApplication sharedApplication] openURL:url];
}
}

检查新版本 更新  第二种方法

// 获取appStore版本号
NSString *url = [[NSString alloc] initWithFormat:@"http://itunes.apple.com/lookup?id=%@",@""]; [self Postpath:url]; #pragma mark -- 获取数据
-(void)Postpath:(NSString *)path
{ NSURL *url = [NSURL URLWithString:path];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:]; [request setHTTPMethod:@"POST"]; NSOperationQueue *queue = [NSOperationQueue new]; [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response,NSData *data,NSError *error){
NSMutableDictionary *receiveStatusDic=[[NSMutableDictionary alloc]init];
if (data) { NSDictionary *receiveDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
if ([[receiveDic valueForKey:@"resultCount"] intValue]>) { [receiveStatusDic setValue:@"" forKey:@"status"];
[receiveStatusDic setValue:[[[receiveDic valueForKey:@"results"] objectAtIndex:] valueForKey:@"version"] forKey:@"version"];
}else{ [receiveStatusDic setValue:@"-1" forKey:@"status"];
}
}else{
[receiveStatusDic setValue:@"-1" forKey:@"status"];
} [self performSelectorOnMainThread:@selector(receiveData:) withObject:receiveStatusDic waitUntilDone:NO];
}]; } -(void)receiveData:(id)sender
{
NSLog(@"receiveData=%@",sender); } 最后打印出来的字典中就包含 版本号 receiveData={
status = ;
version = "1.0.0";
}
