initWithNibName不起作用

Question

Just ran into this very frustrating problem when trying to add a new view, I have 2 different types of view: LargeCoverViewController and CoverViewController .

I created a LargeCoverViewController like this:

LargeCoverViewController *tmpCover = [[LargeCoverViewController alloc] initWithNibName:@"LargeCoverViewController" bundle:nil andIssue:issue];

That just works, but when I try to create a CoverViewController , it refuses to work

CoverViewController *tmpCover = [[CoverViewController alloc] initWithNibName:@"CoverViewController" bundle:nil andIssue:issue];

I'm thinking it has something to do with the .xib file, when I do like this it "works" again

CoverViewController *tmpCover = [[CoverViewController alloc] initWithNibName:@"LargeCoverViewController" bundle:nil andIssue:issue];

In Interface Builder the class is set properly, my view is linked up correctly. (It's basically just a copy of the LargeCoverViewController), am I still missing something? It's getting very frustrating ...

EDIT: My application doesn't crash, if my nibname was wrong the application should crash, which isn't the case here.

Answer 1

Try creating new separate XIB file rather copying whole XIB file and then copy the UI outlets and views from other XIB to this newly created XIB file.

Sometimes, Xcode gets confused with copy-pasting. I know this is not proper solution but sometimes it works. :)

Answer 2

复制ViewController时，文件所有者的自定义类保持不变，因此将其更改为新的ViewController，并在更改后再次绑定视图。

Answer 3

Is your application getting crashed on that line? Check the console for the logs. You may have got error messages or crash logs.

If you copied XIB resources from any other XIB then check for the linked outlets with objects which may not be available to this new class.

I hope this will help you and will able to resolve the issue.
