Is it possible to present a UIAlertView and not continue executing the rest of the code in that method until the user responds to the alert?

推荐答案

我猜你的意思是停止设备运行你在alertview之后编写的下一个代码

I guess stopping the code you meant was to stop the device to run the next code you have written after the alertview

为此，只需在您的 alertview 之后删除您的代码并将该代码放入 alertview 委托

For that just remove your code after your alertview and put that code in the alertview delegate

-(void) yourFunction
{
     //Some code
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Your Message" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [alert show];
            [alert release];
     //Remove all your code from here put it in the delegate of alertview
}
-(void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:    (NSInteger)buttonIndex 
{
if(buttonIndex==0)
    {
        //Code that will run after you press ok button 
    }
}

不要忘记在 .h 文件中包含 UIAlertViewDelegate

Dont forget to include UIAlertViewDelegate in the .h file
