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。
