如何一起使用xib和一个UIView子类？

问题描述

我想创建几个自定义视图，一系列可重用的UI组件，并且不希望在UIView子类中的代码中布置UI。我想使用一个xib。我自己使用了一个xib。我用iteself使用了一个UIView子类。但我没有一起使用它们。我如何附加他们彼此？我想在自定义视图中使用IBOutlets访问UILabels。

I'd like to create a couple of custom views, sort of reusable UI components, and would prefer to not layout the UI in code in the UIView subclass. I'd like to use a xib for that. I've used a xib by itself. And I've used a UIView subclass by iteself. But I haven't used them together. How do I "attach" them to one another? I'd like to use IBOutlets to access the UILabels in my custom view.

这种事情是否有效？

NSArray *xib = [[NSBundle mainBundle] loadNibNamed:@"MyCustomView" owner:self options:nil];
MyCustomView *view = [xib objectAtIndex:0];
view.myLabel.text = @"fred";

推荐答案

是的，将非父级的xibs加载到viewControllers

Yes that's the way that it works when you're loading xibs that aren't parents to viewControllers

只是假设你要得到你正在寻找的返回的NSArray的索引0，这是什么使得使用类型检查是好的。

You can't always just assume that you're going to get exactly what you're looking for out of index 0 of the returned NSArray, which is what makes it good to use type checking.

NSArray *xibArray = [[NSBundle mainBundle] loadNibNamed:@"MyCustomView" owner:nil options:nil];
MyCustomView *myView = nil;
for (id xibObject in xibArray) {
//Loop through array, check for the object we're interested in.
    if ([xibObject isKindOfClass:[MyCustomView class]]) {
        //Use casting to cast (id) to (MyCustomView *)
        myView = (MyCustomView *)xibObject;
    }
}
