UIView.animateWithDuration in Swift 2.0?
提问by Jadekin
Before explain my problem, it is important to say that I already implemented the suggestion made in this questionand I think my doubts about this animateWithDurationmethod are quite different, despite both questions having a very similar title.
在解释我的问题之前，重要的是要说我已经实施了这个问题中提出的建议，我认为我对这种animateWithDuration方法的怀疑是完全不同的，尽管两个问题的标题非常相似。
So, I am a Swift newbie and I am doing some small projects in Swift, based on previous Objective C demos that I did before.
所以，我是一个 Swift 新手，我正在 Swift 中做一些小项目，基于我之前做过的 Objective C 演示。
This is my Objective C code:
这是我的目标 C 代码：
- (void)moveSideBarToXposition: (int) iXposition{
[UIView animateWithDuration:0.5f
delay:0.1
options: UIViewAnimationOptionTransitionNone
animations:^{ self.mainView.frame = CGRectMake(iXposition, 20, self.mainView.frame.size.width, self.mainView.frame.size.height); }
completion:^(BOOL finished){
if (self.isSidebarHidden==YES) {
self.isSidebarHidden = NO;
}
else{
self.isSidebarHidden = YES;
}
}];
}
And this is my Swift version:
这是我的 Swift 版本：
func moveSideBarToXposition(iXposition: Float) {
UIView.animateWithDuration(0.5, delay: 1.0, options: UIViewAnimationTransition.None, animations: { () -> Void in
self.contentView.frame = CGRectMake(iXposition, 20, self.contentView.frame.size.width, self.contentView.frame.size.height)
}, completion: { (finished: Bool) -> Void in
if isMenuHidden == true {
isMenuHidden = false
} else {
isMenuHidden = true
}
})
}
And I get this error.
我收到这个错误。
Cannot invoke 'animateWithDuration' with an argument list of type '(Double, delay: Double, options: UIViewAnimationTransition, animations: () -> Void, completion: (Bool) -> Void)'
无法使用类型为 '(Double, delay: Double, options: UIViewAnimationTransition, animations: () -> Void, completion: (Bool) -> Void)' 的参数列表调用 'animateWithDuration'
I read the documentation but actually I am not sure what the problem is.
我阅读了文档，但实际上我不确定问题是什么。
Btw, i am working on Xcode 7 and Swift 2.0
顺便说一句，我正在使用 Xcode 7 和 Swift 2.0

You are passing enum of type UIViewAnimationTransitionto an argument which requires type UIViewAnimationOptions(optionsargument)
您正在将类型的枚举传递UIViewAnimationTransition给需要类型UIViewAnimationOptions（options参数）的参数
Here is the correct syntax with the correct enum value:
这是具有正确枚举值的正确语法：
func moveSideBarToXposition(iXposition: Float) {
let convertedXposition = CGFloat(iXposition)
UIView.animateWithDuration(0.5, delay: 1.0, options: UIViewAnimationOptions.TransitionNone, animations: { () -> Void in
self.contentView.frame = CGRectMake(convertedXposition, 20, self.contentView.frame.size.width, self.contentView.frame.size.height)
}, completion: { (finished: Bool) -> Void in
// you can do this in a shorter, more concise way by setting the value to its opposite, NOT value
isMenuHidden = !isMenuHidden
})
}
