【问题描述】：

点击时，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];

如何在点击时做出这样的形状？这叫什么？这是我为行动所做的代码： - (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：（默认不会消失）

这封信最后是怎么写的？我记得我昨天回答了你的一个问题。
在我还没加代码和图片之前，所以我再问1个时间来弄清楚s.o是否有答案！我还要求你给我一些代码，所以我再问1次！对不起，我不编辑旧的并制作新的！
这是我单击按钮时所做的代码： - (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]; if (onSetTextFieldCallBack!= nil) { NSMutableString *c = (NSMutableString *)[[(UIButton *)sender titleLabel] text]; self.onSetTextFieldCallBack (c); } }

【解决方案1】：

为您的按钮添加两个目标：

[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
  }];
}
