So this has been quite painful for something that should be trivial. Here is what I did: Use xcassets I decided to use .xcassets versus the .xib for launch. I deleted the .xib. If you have images.xcassets already in your project then great, otherwise you can add one from File>New>file: Create a Launch Image Set … Read more
In AppDelegate.swift, in application(_:didFinishLaunchingWithOptions:) I put the following: UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0) UINavigationBar.appearance().tintColor = UIColor.white UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white] (For Swift 4 or earlier use NSAttributedStringKey instead of NSAttributedString.Key) For titleTextAttributes, the docs say: You can specify the font, text color, text shadow color, and text shadow offset … Read more
If your UI is laid out in a Storyboard, you can set an NSTimer in viewDidLoad of your first ViewController and then call performSegueWIthIdentifier when the timer fires: class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. let timer = Timer.scheduledTimer(interval: 8.0, … Read more
You can use the function collectionView with the parameter didSelectItemAtIndexPath func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { let selectedCell:UICollectionViewCell = myCollectionView.cellForItemAtIndexPath(indexPath)! selectedCell.contentView.backgroundColor = UIColor(red: 102/256, green: 255/256, blue: 255/256, alpha: 0.66) } This creates a constant for the selected UICollectionViewCell, then you just change the background’s color And then for return to the original color … Read more
I’ve done with the following steps. Create a framework project, for example named “FooKit”. (Cocoa Touch Framework to be selected) Create a “.swift” file and add a public symbol, for example public func foo(), to it. Create an use-side (app) project. (I’ve chosen Single View Application) Open the root directory of “FooKit” by Finder, drag … Read more
This simple C-function: dispatch_async(dispatch_get_main_queue(), { // DO SOMETHING ON THE MAINTHREAD self.tableView.reloadData() }) What about launching your function with: dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { loadAlbums() }) in viewDidLoad()?
Indeed nth-child doesn’t work on IOS8. Switching for nth-of-type did the trick for me. It’s well supported https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-of-type That said if you want to take no chance, you can detect IOS 8 as follow. function isIOS8() { if (“600.1.4” == $.browser.version || ~navigator.userAgent.indexOf(‘OS 8_’) ){ return true; } return false; } var i=0, $el = … Read more
The easiest way to get the height is sizeThatFits. Use it like this: Objective-C CGFloat maxLabelWidth = 100; CGSize neededSize = [label sizeThatFits:CGSizeMake(maxLabelWidth, CGFLOAT_MAX)]; Swift 3.0 let maxLabelWidth: CGFloat = 100 let neededSize = label.sizeThatFits(CGSize(width: maxLabelWidth, height: CGFloat.greatestFiniteMagnitude)) The height your label needs is neededSize.height. Note that im using CGFLOAT_MAX for the size height, to … Read more
You need to add the NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key to your plist if you haven’t already, they are now mandatory, iOS8+ requires one of these two strings to be set to use locations. Which one you use depends on how you intend ask for the location. Use NSLocationAlwaysUsageDescription for apps that want to use the … Read more
I answered this in another post: Chartboost integration issues with XCode 6.1 EXPLANATION: It seems like some pods and libraries don’t bother importing the basic frameworks as they expect your code to already have them. This doesn’t work with Swift as the way to import frameworks changed. All you need to do is to add … Read more
