Question

Is it possible to access the NSControl on a NSWindow using tag?
I used the code below but it warned

NSWindow may not response to viewWithTag

NSButton *a=(NSButton * )[self.window
viewWithTag:tag];

Welcome any comment

Thanks

Unlike UIWindow in Cocoa Touch, NSWindow does not inherit from NSView, and thus does not implement that method. You probably want to get the contentView of the window, and then look up the tag on that.
