呈现一个模态视图控制器
我的应用程序的两个不同部分中有相同的代码。 在一个部分中它被完美执行，而在另一部分中它被完全忽略。我设置了一个断点，并观察程序遍历该代码的每一行，而没有加载它应该加载的下一个 xib/类。
这是代码：
UIViewController *nextController = [[ClassNameViewController alloc] initWithNibName:@"MatchingView" bundle:nil];
[nextController performSelector:@selector(setDelegate:) withObject:self];
[self presentModalViewController:nextController animated:YES];
有什么想法为什么这可能会被忽略并且不显示我的 viewController 吗？
I have this same piece of code in two different parts of my app.
In one section it is executed perfectly, and in the other it is completely ignored. I've put in a breakpoint and watched the program go through each line of this code without loading the next xib/class it is supposed to.
Here is the code:
UIViewController *nextController = [[ClassNameViewController alloc] initWithNibName:@"MatchingView" bundle:nil];
[nextController performSelector:@selector(setDelegate:) withObject:self];
[self presentModalViewController:nextController animated:YES];
Any ideas why this might be getting ignored and not presenting my viewController?

我在 viewDidLoad 中有这段代码并将其移动到 viewDidAppear 使其工作。
