Lottie-ios: Animation Does not play

[Ahmeddben]

Hi there,

I have updated to Lottie 2.1.5, the app does not crash or anything. The problem I have is when I set the entry point on the ViewController with the animation View the animation plays every time. But, when I have the animation happen after the user has gone trough 3 different ViewControllers for onboarding the animation does not play. I am using this animation: https://www.lottiefiles.com/433-checked-done

I am on Swift 3 and xcode 8.3.3

Thanks!

Can I see the code example for how, and where, you are setting up the animation?

[Ahmeddben]

Sure!

Setting up the animation on viewDidLoad. The only thing I have in this VC is the animation.

Code:

` let animationView = LOTAnimationView(name:"checked_done")
animationView.frame = CGRect(x:0 , y:0 , width: self.view.frame.size.width , height: self.view.frame.size.height )
animationView.center = self.view.center
animationView.contentMode = .scaleAspectFill
self.view.addSubview(animationView)
animationView.play() { (finished) in
self.performSegue(withIdentifier: "goToProfileVC", sender: nil)
}

}

`

Animation not playing for me either I'm on XCode Version 9.1 & Swift 4

If you call play twice, it causes issues... make sure you only call once and call after viewDidLoad

bumping this. I'm also using XCode 9 and Swift 4. Animations worked when I was using Swift 3. Please help!

edit: My animation works in Swift 4, also when it's added to a root view controller. However, it is not working in any modals that are pushed onto the stack. The subview is added, the Lottie file appears, but is not animated. When I print animationView.isAnimationPlaying, I get "true".

my code:

    var animationView: LOTAnimationView?

    self.animationView = LOTAnimationView(name: "favourite_app_icon")
    self.animationView!.loopAnimation = true
    self.view.addSubview(animationView!)
    animationView?.play()
    print(animationView?.isAnimationPlaying)

Theres a bug that causes the animation to freeze if play is called inside of viewDidLoad.
You can move play to viewDidAppear.

I believe this bug is fixed on master. Will be releasing soon.

Hi, was this bug fixed on master? I'm on 2.5.0 Swift 4. I'm having the same issue. When I print "is playing" I get true as well. It works for some of the animations, for others it doesn't play and for others it doesn't even appear.

[Graystripe17]

I'm an idiot. It's because the frames are so big that the animations were pushed off the screen 😆

Sometimes I can't believe how a UX library can be so complex and beautiful yet I can't even use it properly.
