View controllers are not just for the top level scene. We often place view controllers within view controllers. It’s called “view controller containment” and/or “child view controllers”. (BTW, view controller containers are, in general, a great way to fight view controller bloat in traditional UIKit apps, breaking complicated scenes into multiple view controllers.) So, Go … Read more
This will work properly: #import <QuartzCore/CAAnimation.h> CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@”shadowOpacity”]; anim.fromValue = [NSNumber numberWithFloat:1.0]; anim.toValue = [NSNumber numberWithFloat:0.0]; anim.duration = 1.0; [vv.layer addAnimation:anim forKey:@”shadowOpacity”]; vv.layer.shadowOpacity = 0.0; For Swift 3.0: let animation = CABasicAnimation(keyPath: “shadowOpacity”) animation.fromValue = layer.shadowOpacity animation.toValue = 0.0 animation.duration = 1.0 view.layer.add(animation, forKey: animation.keyPath) view.layer.shadowOpacity = 0.0
Hope this help… [[yourSuperView subviews] makeObjectsPerformSelector:@selector(setUserInteractionEnabled:) withObject:[NSNumber numberWithBool:FALSE]]; which will disable userInteraction of a view’s immediate subviews..Then give userInteraction to the only view you wanted yourTouchableView.setUserInteraction = TRUE; EDIT: It seems in iOS disabling userInteraction on a parent view doesn’t disable userInteraction on its childs.. So the code above (I mean the one with makeObjectsPerformSelector:)will … Read more
Just write your own method for the flip using Core Animation Transforms. – (void)verticalFlip{ [UIView animateWithDuration:someDuration delay:someDelay animations:^{ yourView.layer.transform = CATransform3DMakeRotation(M_PI,1.0,0.0,0.0); } completion:^{ // code to be executed when flip is completed }]; } Make sure you have the Core Animation libraries/frameworks added and included and also have included math.h if you want to use … Read more
If the masksToBounds property is set to YES, any sublayers of the layer that extend outside its boundaries will be clipped to those boundaries. Think of the layer, in that case, as a window onto its sublayers; anything outside the edges of the window will not be visible. When masksToBounds is NO, no clipping occurs, … Read more
Keep a reference to the sublayer added Remove the sublayer from the super layer when not needed. The code would be like: Obj C: [thesublayer removeFromSuperlayer] Swift: thesublayer.removeFromSuperlayer() //thesublayer is the name of the layer you want to remove
I think the proper way of thinking of shadow is, the shadow belongs to the object, which is the button, the uiview, not just part of the side. Imagining there is a virtual light source. You can’t really just create a shadow for one side. With that being said, the shadow will always be the … Read more
With Swift and XCode 6 you can do this. Click the UIView element in Storyboard, and go to identity inspector. In the user defined runtime attributes, enter: layer.borderWidth number 1 If you want nice looking corners layer.cornerRadius number 5 layer.masksToBounds boolean true Now this will give you a border but to set the colour you … Read more
Edit: Using the new concept of Size Classes introduced in Xcode 6, you can easily setup different constraints for specific size classes in Interface Builder. Most devices (e.g. all current iPhones) have a Compact vertical size class in landscape mode. This is a much better concept for general layout decisions than determining the device’s orientation. … Read more
The category method you suggest is the “right” way to do it—you don’t necessarily have a guarantee of those constants keeping their value. From looking at how they’re defined, though, it seems you could just do animationOption = animationCurve << 16; …possibly with a cast to NSUInteger and then to UIViewAnimationOptions, if the compiler feels … Read more
