推荐答案

你可以制作一个 UIView 使用一些自定义艺术作品，并在视图顶部显示动画作为弹出框，其中包含一些按钮：

You could make a UIView with some custom artwork and display it with an animation on top of your view as a "popover" with some buttons like so:

UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(25, 25, 100, 50)]; //<- change to where you want it to show.

//Set the customView properties
customView.alpha = 0.0;
customView.layer.cornerRadius = 5;
customView.layer.borderWidth = 1.5f;
customView.layer.masksToBounds = YES;

//Add the customView to the current view
[self.view addSubview:customView];

//Display the customView with animation
[UIView animateWithDuration:0.4 animations:^{
    [customView setAlpha:1.0];
} completion:^(BOOL finished) {}];

不要忘记 #import< QuartzCore / QuartzCore.h> ，如果你想使用 customView.layer 。

Don't forget to #import <QuartzCore/QuartzCore.h>, if you want to use the customView.layer.
