虽然App Store能够提醒用户软件更新,但很多用户不会主动去更新一大堆的软件(我机器上待更新的软件在100个左右)。如果在软件开启时提醒用户更新 或者 更多中设置“检查更新”项,效果会好很多。


    1. NSString *version = @"";  
    2. NSURL *url = [NSURL URLWithString:@"http://itunes.apple.com/lookup?id=<</span>Your app ID>"];  
    3. versionRequest = [ASIFormDataRequest requestWithURL:url];  
    4. setRequestMethod:@"GET"];  
    5. setDelegate:self];  
    6. setTimeOutSeconds:150];  
    7. addRequestHeader:@"Content-Type" value:@"application/json"];   
    8. startSynchronous];  
    9.  
    10. string of our REST call  
    11. NSString* jsonResponseString = [versionRequest responseString];  
    12.  
    13. NSDictionary *loginAuthenticationResponse = [jsonResponseString objectFromJSONString];  
    14.  
    15. NSArray *configData = [loginAuthenticationResponse valueForKey:@"results"];  
    16.  
    17. (id config in configData)   
    18. {  
    19.    version = [config valueForKey:@"version"];  
    20. }  
    21. your version with the version in app store  
    22. (![version isEqualToString:[itsUserDefaults objectForKey:@"version"]])   
    23. {  
    24.    ProAlertView *createUserResponseAlert = [[ProAlertView alloc] initWithTitle:@"New Version!!" message: @"A new version of app is available to download" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles: @"Download", nil];  
    25. show];   
    26. release];  
    27. }




    1. (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {  
    2.    // the user clicked one of the OK/Cancel buttons  
    3.    if (buttonIndex == 1)  
    4.    {  
    5.        NSString *iTunesLink = @"itms-apps://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftwareUpdate?id=<</span>appid>&mt=8";  
    6.        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];  
    7.    }  
    8. }




    以Remote (http://itunes.apple.com/app/remote/id284417350?mt=8) 软件为例,请求http://itunes.apple.com/lookup?id=284417350返回的数据为:
