UIAlertView button action?
提问by JohnAnge Kernodle
I have an UIAlertViewthat shows with this code that asks you to rate the application in the appstore.
我有一个UIAlertView显示此代码的内容，要求您对应用商店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];
But I cannot figure out how to add an action to the OK button that takes you to the app in the AppStore.
但我不知道如何向 OK 按钮添加一个动作，将您带到AppStore 中的应用程序。

How about this?
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"]];
}
}

You want something like the following:
您需要类似以下内容：
- (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
}
}
NSLog's appear in the console when you press a button and help out whenever you want to debug/test anything.
当您按下按钮并在您想要调试/测试任何东西时提供帮助时，NSLog 会出现在控制台中。
Then for the action that you want, you'd write something like:
然后对于您想要的操作，您可以编写如下内容：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"url_to_app_store"]];

in swift : use this block of code to show alert message.
在 swift 中：使用此代码块显示警报消息。
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)
