我正试图在键盘显示时向上移动视图,因此它不会掩盖屏幕,但由于某种原因,它-(void)DidBeginEditing: (UITextField *)textfield无法正常工作.

- (void)textFieldDidBeginEditing:(UITextField *)ga1
{
    /* should move views */
    self.view.center = CGPointMake(self.view.center.x, self.view.center.y + 220);
}

- (void)textFieldDidEndEditing:(UITextField *)ga1
{
    /* should move views */
    self.view.center = CGPointMake(self.view.center.x, self.view.center.y - 220);

}

它也没有进入方法,谁能告诉我为什么？
