解决方法
您可以使用一些自定义艺术品制作UIView,并在视图顶部显示动画作为“popover”,其中包含一些按钮：
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) {}];
如果要使用customView.layer,请不要忘记#import< QuartzCore / QuartzCore.h>.
