IOS Swift : Popup Custom view as alert box
<p><p>**我用文字和图像设计了自己的 View 。</p>
<p>我想将此显示为警报 View 或仅显示为窗口</p>
<p>如何将 .modalPresentationStyle 用作 .Custom 并实现这一点</p>
<p>我应该使用 ViewController 还是直接显示 View </p>
<pre><code>@IBAction func BtnClickFnc(sender: AnyObject)
{
let MsgBoxVar = MsgBoxCls()
MsgBoxVar.modalPresentationStyle = .Custom
MsgBoxVar.preferredContentSize = CGSizeMake(200, 400)
self.presentViewController(MsgBoxVar, animated: true, completion: nil)
</code></pre>
<p>}</p>
<pre><code>class MsgBoxCls: UIViewController
{
override func viewDidLoad()
{
view.addSubview(NamVyuCls(frame: CGRectMake(50,50,200,200)))
}
}
class NamVyuCls: UIView
{
override public init(frame: CGRect)
{
super.init(frame: frame)
layer.borderWidth = 2
layer.borderColor = UIColor.darkGrayColor().CGColor
layer.cornerRadius = 10
// Code Todo
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
</code></pre></p>

var NamVyuVar: NamVyuCls!
@IBAction func BtnKlkFnc(sender: AnyObject)
{
BgdVyuVar = UIView(frame: view.frame)
BgdVyuVar.backgroundColor = UIColor(red: 255/255, green: 255/255, blue: 225/255, alpha: 0.5)
BgdVyuVar.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.DsmVyuFnc)))
self.view.addSubview(BgdVyuVar)
NamVyuVar = NamVyuCls()
NamVyuVar.frame = CGRectMake(self.view.frame.width / 2 - 100,self.view.frame.height / 2 - 100,200,200)
self.view.addSubview(NamVyuVar)
UIView.animateWithDuration(0.5, delay: 0.1, options: .TransitionNone,
animations:
{
self.view.bringSubviewToFront(self.NamVyuVar)
},
completion: nil)
}
func DsmVyuFnc()
{
BgdVyuVar.removeFromSuperview()
NamVyuVar.removeFromSuperview()
}
</code></pre></p>
