presentedVC
如何知道它是否出现:
present(presentedVC, animated: true, completion: nil)
或通过:
present(presentedVC, animated: false, completion: nil)
答案 0 :(得分:0)
您可以在呈现的视图控制器中取一个标志(bool类型的变量),并在呈现该视图控制器之前将其设置为yes或no!并且你可以在你呈现的viewcontroller中到处使用那个标志!就是这样!
例如,
TestViewController *tvc = [[TestViewController alloc]initWithNibName:@"TestViewController" bundle:nil];
tvc.isAnimated = NO;
[self presentViewController:tvc animated:NO completion:nil];
斯威夫特:
let nvc = NewViewController()
nvc.isAnimated = false
self.present(nvc, animated: false, completion: nil)
