Re: UINavigationBar content margins in UIPresentationController subclass

The most relevant looking bug I can find seems to involve pushing & popping view controllers. That said, setting the preferredContentSize on the navigation controller directly should always work. Setting preferredContentSize directly on the navigation controller works as expected. I’m more ref

Re: UINavigationBar content margins in UIPresentationController subclass

Thanks, David. Unfortunately, UINavigationController isn’t currently an option as it doesn’t reliably bubble up preferredContentSize changes, which we have a strong dependency on and is fairly dynamic in our use case. As of 10.0, it only seems to adapt and forward the very first preferredConte

UIStackView: Variable Spacing

What’s the best way to achieve variable spacing between children of a UIStackView? I know that a popular approach is to add an empty dummy view to act as padding, but this is being used in a UITableView cell, so scrolling performance is critical and the implicit constraints created by adding a

Re: How can I get a single threaded network call in ObjC on iOS?

I agree with Gary, but if something about your structure makes that difficult, there’s also a queue suspend/resume approach: let queue = dispatch_queue_create("", DISPATCH_QUEUE_SERIAL) dispatch_async(queue) { dispatch_suspend(queue) myFirstNetworkCall({ (let result) in dispatch_

UINavigationController: Clean interactive transition to view controller without navigation bar?

It seems like it *should* work. Are you sure you don’t have a typo in your addObserver: method? Considering that you’re using the dictionary’s property setter, keyPathsForValuesAffecting shouldn’t even be necessary. When I apply KVO, I try to mitigate the potential unsafely of key paths strin
