Loaded some nib but the view outlet is not set

This problem is encountered when using the Initwithnibname function and using the View property of the Viewcontroller generated by the nib file.

Load Loc.xib

Uiviewcontroller * UIVC = [[Uiviewcontroller alloc] initwithnibname:@ "loc" Bundle:nil];

[Self.view AddSubview:UIVC.view];

[UIVC release];

NIBNAME[2203:207] * * * terminating app due to uncaught exception ' nsinternalinconsistencyexception ', Reason: '-[ Uiviewcontroller _loadviewfromnibnamed:bundle:] Loaded the "LOC" nib but the view outlet is not set. '

Surface meaning refers to the nib file that we loaded, and the "View" property value is not set.

The actual situation here: not the VC generated by the View property value is nil, but the resulting VC does not have view this property. We are using the VC defined by Uiviewcontroller, why does the VC (view Controller) have no view properties?

(How logical a statement is less than a successful complete operation, begin:)

Solution:

1. Click on the xib file we want to load

2. On the right, select File ' Owner

3. In the "Custom Class" property setting of the File's Owner's tab, change the value of Class to the corresponding VC, which is changed to Uiviewcontroller,

4. At this point, in the file's Owner's tab, the View property of the "To connect setting" appears, and our compiler tells us the view in the view outlet is not set. When File ' s Owner's class is NSObject, there is no view attribute.

Connect the View property,

5. Win+r, OK.
