SubViewWithNib

Demonstration how to add a sub view to a view in an iOS application where the sub view is connected to a nib file.

Note, you can use a UIView object as a sub view but not a UIViewController object. First, create a UIView class. Unlike UIViewController subclasses you won't have the option to create a nib file to go along with it. This is fine. Create the nib file by itself as a separate step. Open the nib file and go to the Identity Inspector for the top-level view object. Change the custom class to the corresponding view class you just previously created. For this example, place a UILabel in the view and create an outlet for it in the corresponding view class. Now you can place this as a sub view in any view you want to and can change the label programatically as well.

// Create an instance of UIView (FooView).
FooView *fooView = [[[NSBundle mainBundle] loadNibNamed:@"FooView" owner:self options:nil] objectAtIndex:0];

// Tell it where to go. Otherwise, it'll appear in the upper left corner.
fooView.frame = CGRectMake(10, 150, 300, 90);

// Modify the text of the label.
fooView.fooLabel.text = @"Modified Label Text";

// Actually add the subview.
[self.view addSubview:fooView];

Using a nib file may be overkill if it contains nothing but a UILabel but you can image how a more complicated nib file might be used in a real application. Comments, Feedback, Suggestions: Michael Luton
