Loaded nib but the 'view' outlet was not s

2018-12-31 22:58发布

I added a new nib file to my project, and tried to load it.

However, when I click on the toolbar icon that is supposed to take me to the view that I created, I get an NSInternalInconsistencyException with the message:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "..." nib but the view outlet was not set.'

So I opened up my nib file, and I see for the view that there are no referencing outlets set. However, I try to click and drag the circle for "new referencing outlet" to File's Owner, but it won't let me...what do I need to do to get my view to display?

In my case , the designated initializer - (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil in ***ViewController class was implemented so even if when I call other initializer to initialize the object ,the designated initializer will be called .

So to resolve this problem checking wether the - (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil is also a proper way.

My issue with this was caused by having a duplicate nib in the class folder that did not have the view set. xcode seemed to be choosing one nib for a build and then the other the next time I built the project. Just deleted the other one. Looks good. Doh!

Just spent more than hour trying to find out why my view property is not set in my view controller upon initiating it from nib. Remember to call "[super initWithNibName...]" inside your view controller's initWithNibName.

I can generally fix it by remaking the connection between File's Owner and the view. Control-drag from the File's owner to your View (in IB) and select view from the pop-up menu.

Just had the same error in my project, but different reason. In my case I had an IBOutlet setup with the name "View" in my custom UITableViewController class. I knew "view" was special because that is a member of the base class, but I didn't think View (different case) would also be a problem. I guess some areas of Cocoa are not case-sensitive, and probably loading a xib is one of those areas. So I just renamed it to DefaultView and all is good now.

I just fixed this in mine. Large project, two files. One was "ReallyLargeNameView" and another was "ReallyLargeNameViewController"

Based on the 2nd answer chosen above, I decided I should clean my build. Nada, but I was still suspect of XCode (as I have two identical classes, should abstract them but eh...) So one's working, one's not. File's owner names are so far as copy and pasted, outlets rehooked up, xCode rebooted, still nothing.

So I delete the similar named class (which is a view). Soon, new error "outlet inside not hooked up" literally was "webView not key value" blah... basically saying "Visual Studio's better". Anyway... I erase the smaller named file, and bam, it works.

XCode is confused by similar-named files. And the project is large enough to need rebooting a bit, that may be part of it.

Wish I had a more technical answer than "XCode is confused", but well, xCode gets confused a lot at this point. Unconfused it the same way I'd help a little kid. It works now, :) Should benefit others if the above doesn't fix anything.

Always remember to clean your builds (by deleting off the simulator too)
