将xib分配给Swift中的UIView
将xib分配给Swift中的UIView
提问于 2014-06-23 23:45:59
在目标c中，它可以在init方法中完成，方法是
-(id)init{
self = [[[NSBundle mainBundle] loadNibNamed:@"ViewBtnWishList" owner:0 options:nil] objectAtIndex:0];
return self;
}但是当我在swift中这样做的时候
init(frame: CGRect) {
self = NSBundle.mainBundle().loadNibNamed("ViewDetailMenu", owner: 0, options: nil)[0] as? UIView
}无法在方法中分配给自己错误显示。现在我的方法是创建一个视图，并将从nib加载的视图添加到其中。谁有更好的主意？

这对我很有效。
override func awakeAfterUsingCoder(aDecoder: NSCoder) -> AnyObject? {
if self.subviews.count == 0 {
return loadNib()
}
return self
}
private func loadNib() -> YourCustomView {
return NSBundle.mainBundle().loadNibNamed("YourCustomViewNibName", owner: nil, options: nil)[0] as YourCustomView

在Xcode 7 beta 4，Swift 2.0中测试。下面的代码将xib分配给UIView。您可以在情节提要中使用此自定义xib视图，还可以访问IBOutlet对象。
import UIKit
@IBDesignable class SimpleCustomView:UIView
{
var view:UIView!;
@IBOutlet weak var lblTitle: UILabel!
@IBInspectable var lblTitleText : String?
{
get{
return lblTitle.text;
}
set(lblTitleText)
{
lblTitle.text = lblTitleText!;
}
}
override init(frame: CGRect) {
super.init(frame: frame)
loadViewFromNib ()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
loadViewFromNib ()
}
func loadViewFromNib() {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "SimpleCustomView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
view.frame = bounds
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
self.addSubview(view);
}
}以编程方式访问customview
self.customView = SimpleCustomView(frame: CGRectMake(100, 100, 200, 200))
self.view.addSubview(self.customView!);Stack Overflow用户

这可能是你的一个解决方案：
Swift 3.x
class func instanceFromNib() -> UIView {
return UINib(nibName: "<<NibFileName>>", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}Swift 2.x
class func instanceFromNib() -> UIView {
return UINib(nibName: "<<NibFileName>>", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as UIView
