Re: iOS 9: Adding CALayer to self.view.layer causes EXC_BAD_ACCESS

FWIW, it still crashes if I change the code to use self.layer instead of _layer: @property (strong,nonatomic) CALayer *layer; . . . self.layer = [[CALayer alloc] init]; [self.layer setDelegate: self]; [self.view.layer addSublayer:self.layer]; -Carl > On Dec 6, 2016, at 12:51

Re: iOS 9: Adding CALayer to self.view.layer causes EXC_BAD_ACCESS

I've wondered about this before, but maybe some Objective-C runtime experts know. Does writing directly to the ivar backing a property bypass the ARC features of the property. For example, will a strong property be retained if you write directly to the ivar? If not, that's your problem. Doug

iOS 9: Adding CALayer to self.view.layer causes EXC_BAD_ACCESS

I get the following crash in my iOS 9 app simply by adding a CALayer to the current view controller's self.view.layer and then dismissing the current view controller. Simplified code: @property (strong,nonatomic) CALayer *layer; . . . _layer = [[CALayer alloc] init]; [_layer
