使用IB从View Controller的视图加载带有XIB的自定义UIView [英] Load custom UIView with XIB from a View Controller's view using IB

问题描述

我有一个使用Interface Builder构建的自定义 UIView （ MyCustomUIView ）。我想将此自定义视图放在 MyViewController 的视图中，该视图也是使用IB设计的。我在 MyViewController 的XIB中放置了一个 UIView 作为子视图，并将它的类设置为 MyCustomUIView 。问题是，当我运行代码时，只显示一个空白视图。 （当我在代码中实例化 MyCustomUIView 时，它显示得很好。）

I have a custom UIView (MyCustomUIView) which is built using Interface Builder. I'd like to place this custom view in MyViewController's view, which is also designed using IB. I've placed an UIView as a subview in MyViewController's XIB and set it's class to MyCustomUIView. The problem is, when I run the code, only a blank view appears. (When I instantiate MyCustomUIView in code, it displays well.)

我只是重写 initWithFrame：方法如下 MyCustomUIView.m ：

- (id)initWithFrame:(CGRect)frame
{
    [[NSBundle mainBundle] loadNibNamed:@"MyCustomUIView" owner:self options:nil];
    self = self.view;
    return self;
}

我该怎么做才能正确加载视图？怎么应该 initWithCoder：看起来像？

What should I do to make the view load properly? How should initWithCoder: look like?

推荐答案

你是对的。 IB使用initWithCoder。 initWithCoder应该看起来与你的其他init方法非常相似：

You are correct. IB uses initWithCoder. initWithCoder should look very similar to your other init methods:

- (id)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        // CUSTOM INITIALIZATION HERE
    }
    return self;
}

一旦你在IB中分配你的班级，你就不需要实例化它了从捆绑中除非我误解了你的意图。

Once you assign your class within IB, you won't need to instantiate it from the bundle unless I'm misunderstanding your intention.
