Iphone Ios应用程序图标类

是否存在与主屏幕上的应用程序图标相对应的UI类

或者类似的按钮，也有摆动效果的方法？

简短回答，否

由开发人员使用SDK重新创建这些效果。制作带有图像（应用图标）的自定义UIButton非常简单。然后，只需添加适当的长按手势处理，即可激活按钮的可编辑状态并开始摆动

-(void)viewDidLoad {
  // make a UIButton
  UIButton *myWiggleButton = [UIButton buttonWithType:UIButtonTypeCustom];
  // set an image for the button
  [myWiggleButton setImage:[UIImage imageNamed:@"my_app_image.png"] forState:UIControlStateNormal];
      // add an action and target for the button
  [myWiggleButton addTarget:self action:@selector(myButtonTapped:)   forControlEvents:UIControlEventTouchUpInside];
      // finally add a long touch gesture recognizer
  UILongPressGestureRecognizer *longPressGesture =
                [[[UILongPressGestureRecognizer alloc]
                  initWithTarget:self action:@selector(startWiggleMode:)] autorelease];
  [myWiggleButton addGestureRecognizer:longPressGesture];
}

-(void)startWiggleMode:(UIGestureRecognizer*)recognizer
{
  // start a wiggling animation for the button.
  // add a UIButton for the 'x' on top of the wiggling button
}

-(void)myButtonTapped:(id)sender
{
  // handle button tap case here.
}
