我有一个显示此代码的UIAlertView
,要求您对appstore中的应用程序进行评分。
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Rate on the Appstore!"
message:@""
delegate:self
cancelButtonTitle:@"Later"
otherButtonTitles:@"OK", nil];
[alert show];
[alert release];
但我无法弄清楚如何将操作添加到“确定”按钮,该按钮会将您带到 AppStore 中的应用。

这个怎么样?
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex != [alertView cancelButtonIndex]) {
NSLog(@"Launching the store");
//replace appname with any specific name you want
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms://itunes.com/apps/appname"]];
}
}
答案 1 :(得分:9)
您需要以下内容:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
NSLog(@"Clicked button index 0");
// Add the action here
} else {
NSLog(@"Clicked button index other than 0");
// Add another action here
}
}
当您按下按钮时,NSLog会显示在控制台中,并在您想要调试/测试任何内容时提供帮助。
然后,对于你想要的动作,你会写一些类似的东西:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"url_to_app_store"]];

:使用此代码块显示警告消息。
let alert = UIAlertController(title: "Alert", message: "This is an alert message", preferredStyle: UIAlertControllerStyle.Alert)
let action = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: {(action:UIAlertAction) in print("This is in alert block")
})
alert.addAction(action)
self.presentViewController(alert, animated: true, completion: nil)
