思路： 通过获取appStore已上传的版本的版本号与手机当前该软件的plist文件中版本号对比。
//检测软件更新
-(void)checkSoftUpgrade{
NSString *version = @"";
NSURL *url = [NSURL URLWithString:@"http://itunes.apple.com/lookup?id=805288402"];
ASIFormDataRequest * versionRequest = [ASIFormDataRequest requestWithURL:url];
[versionRequest setRequestMethod:@"GET"];
[versionRequest setDelegate:self];
[versionRequest setTimeOutSeconds:150];
[versionRequest addRequestHeader:@"Content-Type" value:@"application/json"];
[versionRequest startSynchronous];
//Response string of our REST call
NSString* jsonResponseString = [versionRequest responseString];
NSDictionary *loginAuthenticationResponse = [jsonResponseString objectFromJSONString];
NSArray *configData = [loginAuthenticationResponse valueForKey:@"results"];
for (id config in configData)
{
version = [config valueForKey:@"version"];
download = [config valueForKey:@"trackViewUrl"];
NSLog(@"%@",version);
NSLog(@"%@",[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleVersionKey]);
}
//Check your version with the version in app store
if (![version isEqualToString:[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleVersionKey]])
{
UIAlertView *createUserResponseAlert = [[UIAlertView alloc] initWithTitle:@"New Version!!" message: @"A new version of app is available to download" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles: @"Download", nil];
[createUserResponseAlert show];
}
}
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
// the user clicked one of the OK/Cancel buttons
if (buttonIndex == 1)
{
NSString *iTunesLink = download;
NSLog(@"+++++++%@",iTunesLink);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];
}
}
