【问题描述】:
我正在尝试在没有任何动画的两个视图控制器之间进行自定义 segue。一切都按我的预期工作,只是控制台给我以下消息:
2015-06-16 12:19:01.537 prototyp_2[42453:9048104] 不平衡调用 的开始/结束外观过渡。
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)
}
}
}
这是我的行动:
@IBAction func nextQuestion(sender: AnyObject) {
self.performSegueWithIdentifier("id_forwardSegue", sender: self)
}
