[英]Custom segue without animation in Swift
I'm trying to make custom segue between two view controllers without any animation. 我正在尝试在没有任何动画的情况下在两个视图控制器之间进行自定义选择。 Everything works as I expecting just console giving me following message: 一切正常,正如我期望的那样,只有控制台会给我以下消息:
2015-06-16 12:19:01.537 prototyp_2[42453:9048104] Unbalanced calls to begin/end appearance transitions for . 2015-06-16 12:19:01.537 prototyp_2 [42453:9048104]不平衡的呼叫开始/结束外观转换的。
Here is my code: 这是我的代码:
class Segue_forward: UIStoryboardSegue {
override func perform() {
// zdroj a destinace do lokálních proměnných
var firstVCView = self.sourceViewController.view as UIView!
var secondVCView = self.destinationViewController.view as UIView!
// rozměry displeje
let screenWidth = UIScreen.mainScreen().bounds.size.width
let screenHeight = UIScreen.mainScreen().bounds.size.height
// initial position of destination view
secondVCView.frame = CGRect(x: 0.0, y: 0.0, width: screenWidth, height: screenHeight)
// protože destination VC není subview okna aplikace tak to musime napravit
let window = UIApplication.sharedApplication().keyWindow
window?.insertSubview(secondVCView, aboveSubview: firstVCView)
// animace
UIView.animateWithDuration(0.0, animations: { () -> Void in
firstVCView.frame = CGRectOffset(firstVCView.frame, 0.0, 0.0)
secondVCView.frame = CGRectOffset(secondVCView.frame, 0.0, 0.0)
}) { (Finished) -> Void in
self.sourceViewController.presentViewController(self.destinationViewController as! UIViewController, animated: false, completion: nil)
}
}
}
And here is my action: 这是我的动作:
@IBAction func nextQuestion(sender: AnyObject) {
self.performSegueWithIdentifier("id_forwardSegue", sender: self)
}
Just do it without animation: 不用动画就可以做到:
override func perform() {
self.sourceViewController.presentViewController(self.destinationViewController as! UIViewController, animated: false, completion: nil)
}
展示新的UIViewController和parentViewController:
self.sourceViewController.parentViewController?.presentViewController(YOUR_VIEW_CONTROLLER, animated: false, completion: nil)
