从iOS 8开始,苹果提出新的 UIPopoverPresentationController代替UIPopoverController。代码如下:



//创建你需要显示的controller
UIViewController *cityAlertViewController = [[UIViewController alloc] init]; 
//这里自定义的view
DLpopupView *popupView = [[DLpopupView alloc] initWithFrame:CGRectMake(0.0, 0.0, 
[300, 91) andRestorationName:@“DCpopupView”]; 

cityAlertViewController.view = popupView; 
//设置modal类型
cityAlertViewController.modalPresentationStyle = UIModalPresentationPopover; cityAlertViewController.preferredContentSize = CGSizeMake(300, 91); 
//配置 UIPopoverPresentationController 
UIPopoverPresentationController *cityErrorPopover = cityAlertViewController.popoverPresentationController; 
//设置代理
cityErrorPopover.delegate = self;
//设置相关属性
  cityErrorPopover.sourceView = self.view;
cityErrorPopover.sourceRect = button.frame; cityErrorPopover.permittedArrowDirections = 
UIPopoverArrowDirectionUp; cityErrorPopover.backgroundColor = greenNormal;
// pop跳转
[self presentViewController:cityAlertViewController animated:YES completion:nil];
