It's not a method of UIView; it's a method of various collection objects. And to ensure that it's being called, you must break on the -makeObjectsPerformSelector: line and ensure that: 1. The code is actually reaching that line. 2. self.view is not nil. 3. self.view.subviews is not nil. 4. self.view.subviews actually has objects in it & is therefore not empty. 5. The line is not throwing an exception. For 2, 3, and 4 above, you can use the debugger console and the "po" debugger command to evaluate the code. Note that you will have to use bracket notation instead of dot notation with the po command or it will think you're trying to print the object's internals rather than the result of sending a message to an accessor. For 5, you should turn on breaking on ObjC exceptions in the debugger. You can do that by clicking on the + button in the breakpoints view in Xcode and then choosing to break on exceptions.
