Here’s an example of how to customize the background and title color of a UINavigationBar without having to use an image (in this case, a blue background with a white title AND white status bar): // Set the navigation bar to blue [[UINavigationBar appearance] setBarTintColor:[UIColor blueColor]]; [[UINavigationBar appearance] setTranslucent:NO]; // Set the navigation bar’s title …

Earlier today I had a situation in which the gesture to scroll a UITableView to the top by tapping on the iPhone status bar was not working. Strange and annoying. On doing some investigation, I found a clue on StackOverflow which pointed me in the right direction. It turns out that if you have a nested scroll view …

I discovered this one accidentally since I really did want to open three projects at the same time after opening Xcode. It turns out that the “Open Project…” dialog in Xcode supports multi-select!

I’m not sure if this is helpful but …

Here’s the scenario. You want to display a modal view controller without a navigation bar, and then from that view controller you want to navigate to another view controller that displays a navigation bar. First to get things set up, in the Storyboard we set up the view controller that would be displayed modally. We …
Super important to know during this time of Objective-C to Swift transition. I’ve had to use this technique and it will be good for all Swift developers to have in their kit-bag until we can finally be 100% Swift.

Here is a very simple way to do UIView Animations in Swift. First, you create an IBOutlet for a constraint created in Interface Builder in Xcode – in my case, I had a constraint that anchored to the bottom of the containing view. In the code example, the constraint is named “constraintToAnimate”. You just control …
