IOS78模态半透明弹出框

Posted 2020-06-08

//源Controller中跳转方法实现  

 MKDialogController *controller = [[MKDialogController alloc] init];  

 controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;  

if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {  

   　controller.providesPresentationContextTransitionStyle = YES;  

  　controller.definesPresentationContext = YES;  

 　controller.modalPresentationStyle = UIModalPresentationOverCurrentContext;  

　[self presentViewController:controller animated:YES completion:nil];  

 } else {  

　　 self.view.window.rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;  

     [self presentViewController:controller animated:NO completion:nil];  

　　 self.view.window.rootViewController.modalPresentationStyle = UIModalPresentationFullScreen;  

}  

// 只不过跳转后没有动画效果，有待优化
