iphone - 单击时如何使自定义按钮键像iPhone按钮键一样大

Question

单击时，我想要这张图片中的大字母。

如何为我的新按钮“ក”执行此操作？这是我创建按钮的代码：

consonantButton = [UIButton buttonWithType:UIButtonTypeCustom];

[consonantButton setTitle:@"ក" forState:UIControlStateNormal];
 consonantButton.titleLabel.font = [UIFont fontWithName:@"Hanuman" size:30];
consonantButton.frame = CGRectMake(242.0, 328.0, 27.0, 42.0);
[consonantButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[consonantButton setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateNormal];
//  [consonantButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
//  [consonantButton setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
//  consonantButton.titleLabel.shadowOffset = CGSizeMake(0, -1);

[consonantButton setBackgroundImage:[UIImage imageNamed:@"doneButtonNormal-khmer"] forState:UIControlStateNormal];
//  [consonantButton setBackgroundImage:[UIImage imageNamed:@"doneButtonHighlighted-khmer"] forState:UIControlStateHighlighted];


[consonantButton addTarget:self action:@selector(touchConsonantButton:) forControlEvents:UIControlEventTouchUpInside];

点击时如何制作这样的形状？这叫什么 ？这是我为操作所做的代码： - (void) touchConsonantButton:(UIButton*)sender{ // [self.target performSelector:consonantAction withObject:sender]; consonantButton.frame = CGRectMake(242.0, 310.0, 54.0, 84.0); consonantButton.titleLabel.font = [UIFont fontWithName:@"Hanuman" size:50];}

这是屏幕截图：（默认情况下它不会消失）

Answer 1

将两个目标添加到您的按钮：

[consonantButton addTarget:self action:@selector(touchUpConsonantButton:) forControlEvents:UIControlEventTouchUpInside];
[consonantButton addTarget:self action:@selector(touchDownConsonantButton:) forControlEvents:UIControlEventTouchDownInside];

现在选择器是：

-(void)touchUpConsonantButton(id)sender
{
  UIButton *btnClicked = (UIButton *)sender;
  // your code here
  [UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
    btnClicked.transform = CGAffineTransformMakeScale(2.0f, 2.0f);
  } completion:^(BOOL finished){
    // if you want to do something once the animation finishes, put it here
  }];
}

---

-(void)touchDownConsonantButton(id)sender
{
  UIButton *btnDown = (UIButton *)sender;
   // your code here
  [UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
    btnDown.transform = CGAffineTransformIdentity;
  } completion:^(BOOL finished){
    // if you want to do something once the animation finishes, put it here
  }];
}
