问题 I have a working code from a tutorial but don't understand it completely. Situation: After a button was pressed in my iPhone App an AlertView appears with three buttons. Now I like to check what button the user pressed. CODE FROM THE TUTORIAL: - (IBAction)infoButtonPressed:(id)sender { UIAlertView *myAlert1 = [[UIAlertView alloc]initWithTitle:@"My Alert View 1" message:@"Here we go" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Option1", @"Option2", nil]; [alert show]; } -

问题 I've been moving an alert view slightly higher so i can fit a keyboard on screen as well. I just do this by grabbing the frame of the alert and changing the Y after i have already shown the alert so that the frame variables are legit. This works fine on the simulator, but when I do this on the hardware, the alert starts at the correct position but then almost immediately jumps down to it's original vertical center place. Is the UIAlertView position a fixed thing that isn't supposed to change

问题 Part of my app requires calendar access, which requires a call to the EKEventStore method -(void)requestAccessToEntityType:(EKEntityType)entityType completion:(EKEventStoreRequestAccessCompletionHandler)completion as of iOS 7. I added the request, and everything runs smoothly if the user selects to allow access, but a problem arises if the user denies or has previously denied access. I added a UIAlertView to notify the user if access is denied, but the UIAlertView consistently takes 20-30

问题 This is the current way i'm customizing my buttons: UIAlertView *av = [[UIAlertView alloc] init]; [av addButtonWithTitle:@""]; UIButton *yesButton = [av.subviews lastObject]; [av show]; [yesButton setImage:[UIImage imageNamed:@"test.png"] forState:UIControlStateNormal]; The problem with this is that the original view is still visible around the image I set for the button.
