Xcode 4, Cocoa Title bar removing from interface builders disables textView from editing

Question

I am designing an application without a title bar, however when I remove the title bar using interface builder in Xcode 4 , it causes the editable fields (the ones I tried are textView, and textField) not being editable, despite editable checked in there properties? why this happens and is there anyway to prevent it?

Answer 1

You have to subclass your window and overwrite the following methods:

- (BOOL)canBecomeKeyWindow {
    // because the window is borderless, we have to make it active
    return YES;
}

- (BOOL)canBecomeMainWindow {
    // because the window is borderless, we have to make it active
    return YES;
}
