Edit:With thanks to This situation is muddled up by the fact that
UIViewhandle things differently. For
NSView (desktop Mac development only), you can simply use the following:
[someNSView setSubviews:[NSArray array]];
UIView (iOS development only), you can safely use
makeObjectsPerformSelector: because the
subviews property will return a copy of the array of subviews:
[[someUIView subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];
Thank you to for pointing out that
makeObjectsPerformSelector: appears to modify the
subviews array while it is being enumerated (which it does for
NSView, but not for
Please see behavior-difference-between-uiview-subviews-and-nsview-subviews">this SO question for more details.
Note: Using either of these two methods will remove every view that your main view contains and release them, if they are not retained elsewhere. From Apple's documentation on removeFromSuperview:
If the receiver’s superview is not nil, this method releases the receiver. If you plan to reuse the view, be sure to retain it before calling this method and be sure to release it as appropriate when you are done with it or after adding it to another view hierarchy.
