The interface on WKInterfaceController only provides
public func animateWithDuration(duration: NSTimeInterval, animations: () -> Void)
But what if you want to chain animations with completion blocks like that we are used to in iOS?
Here's an extension of WKInterfaceController that can help you do that.
//delay is a global function that helps us make the code cleaner.
public func delay(delay: NSTimeInterval, closure:() -> ()) {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(delay * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), closure)
}
extension WKInterfaceController {
public func animateWithDuration(duration: NSTimeInterval, animations: () -> Void, completion: () -> ()) {
animateWithDuration(duration) {
animations()
}
delay(duration) {
completion()
}
}
}
You can implement it like this in WKInterfaceController:
animateWithDuration(0.5, animations: {
//Animations
}, completion: {
//Completion
})
