IB and size class-based constraints

I have a size class-enabled storyboard with a view controller that contains two view. They are to be stacked in everything except a compact height situation, in which case they should be side-by-side. So, the lower view has two top constraints. One specifies the space to the other view, the oth

Also, beware subclassing a Non-ARC Class in an ARC Project - you have to have the subclass Non-ARC too. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list. Contact the moderator

Re: UI to allow user to scale and crop image within a circle

Good tip! Thanks, Dave and Quincey. I was pretty sure the problem was something embarrassingly basic. The next step is to redesign the CircleOverlayView to fill its view with black except for the center of the circle. I already learned that filling the view with black and then filling the circl

When to remove Gesture Recognizers

Hi All, I’m adding a Gesture Recognizer to a view in the awakeFromNIB method. This works ok but I’m getting crashes sometimes and I’m wonder it its because I’m not removing it? If so, when is the best place to call RemoveGestureRecognizer? Thanks a lot All the Best Dave __

Re: ARC code in a non ARC app. iOS

Tangentially related: I have a bug ( rdar://10894595 ) open on the Developer Tools (Xcode/clang) to add a #pragma to turn on/off ARC in the source code, for dealing with just such situations. I dunno’ how much work it would be to implement… I imagine not all that much for somebody familiar wi
