UIView.animate - Swift 3 - completion
提问by Chris Allinson
How do I do a simple completion block in Swift 3?
如何在 Swift 3 中做一个简单的完成块？
I want to set self.isOpen = truein the completion of the animation:
我想self.isOpen = true在完成动画时设置：
UIView.animate(withDuration: 0.25, delay: 0.0, options: [], animations: {
self.isOpen = true
self.drawerView?.frame = CGRect(x: 0, y: 0, width: (self.drawerView?.frame.size.width)!, height: (self.drawerView?.frame.size.height)!)
self.contentView?.frame = CGRect(x: 200, y: 0, width: (self.contentView?.frame.size.width)!, height: (self.contentView?.frame.size.height)!)
}, completion: nil)
In passing:
顺便：
It's pretty impossible to learn Swift 3 atm due to NOTHING on the internet working :(
由于互联网上没有任何工作，学习 Swift 3 atm 几乎是不可能的:(
I've also searched this entire document for even a mention of the word "animate" and could not find anything:
我还搜索了整个文档，甚至没有提到“动画”一词，但找不到任何内容：

你像这样添加它：
UIView.animate(withDuration: 0.25, delay: 0.0, options: [], animations: {
self.drawerView?.frame = CGRect(x: 0, y: 0, width: (self.drawerView?.frame.size.width)!, height: (self.drawerView?.frame.size.height)!)
self.contentView?.frame = CGRect(x: 200, y: 0, width: (self.contentView?.frame.size.width)!, height: (self.contentView?.frame.size.height)!)
}, completion: { (finished: Bool) in
self.isOpen = true
})
