(转)iOS如何取得APP的版本信息跟服务器对比进行升级提示?
关键是自动取版本信息:
[NSString stringWithFormat:@"Version %@",[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"]]; [NSString stringWithFormat:@"Build %@",[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"]];
然后对比服务器上的版本,这个你得自己通过WEB提供,示例中就先写出来:
#define APP_DownloadURL @"http://itunes.apple.com/app/id483504146?mt=8" //换成你自己的APP地址 - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if (buttonIndex != [alertView cancelButtonIndex]) { NSURL *url = [NSURL URLWithString:APP_DownloadURL]; [[UIApplication sharedApplication] openURL:url]; } } -(void)alertUpdate:(NSString *)strContent { if (!isAlertUpdateShowed) { isAlertUpdateShowed=YES; UIAlertView *av = [[[UIAlertView alloc] initWithTitle:@"升级提示" message:strContent delegate:self //委托给Self,才会执行上面的调用 cancelButtonTitle:@"以后再说" otherButtonTitles:@"马上更新",nil] autorelease]; [av show]; } } -(void)checkUpdate { NSString* sLastVersion=@"1.1"; //取最新的版本自己去实现 NSString* sLastVersionInfo=@"Test Update Check!"; //取最新的版本介绍自己去实现 if (![sLastVersion isEqualToString:[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"]]) { [self alertUpdate:sLastVersionInfo]; } }
还需要实现一些延时再提醒的处理。
