我使用下面的代碼來移動uitextview和uitextfield。 當鍵盤出現時,alertView應該向上滑動,並在消失後立即滑落。下面的代碼在ios 3.1.2下工作得非常好。但由於某種原因,它不能在ios 4.0下工作.....這個問題似乎是我正在進行的轉換,但我不知道到底發生了什麼問題。如果有人知道解決方案,這將是非常棒的!提前致謝!這裏是我的代碼:iphone sdk:CGAffineTransform無法在iOS 4中使用?
- (void)addItemAction{
workoutName = [[UIAlertView alloc] initWithTitle:@"New Workout" message:@"Insert the name of your new workout:\n " delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Done", nil];
workoutName.cancelButtonIndex = 0;
UITextField *titleField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 90.0, 260.0, 25.0)];
titleField.delegate = self;
titleField.borderStyle = UITextBorderStyleRoundedRect;
titleField.returnKeyType = UIReturnKeyDone;
[workoutName addSubview:titleField];
[workoutName show];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField {
[UIView beginAnimations:nil context:NULL];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0.0, -70.0);
[workoutName setTransform:myTransform];
[UIView commitAnimations];
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
[UIView beginAnimations:nil context:NULL];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0.0, 0.0);
[workoutName setTransform:myTransform];
[UIView commitAnimations];
if ([textField.text length] != 0) {
self.newWorkout = textField.text;
}
else {
self.newWorkout = @"";
}
}
