Interface-Builder：“组合”带有.xib的NSView类

本文介绍了Interface-Builder：“组合”带有.xib的NSView类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想在Interface-Builder中设置一个自定义的NSView，但我不能让它适用于OSX。

I'd like to set up a custom NSView in Interface-Builder, but I don't get it to work for OSX.

在我的ViewController的.xib中，我添加了一个自定义视图并将Class设置为MyCustomView。我创建了MyCustomView.h，MyCustomView.m和MyCustomView.xib。

In my ViewController's .xib, I added a custom view and set the Class to MyCustomView. I created MyCustomView.h, MyCustomView.m and MyCustomView.xib.

在MyCustomView.xib中，我也将Class设置为MyCustomView。在MyCustomView.m中，调用了 - （void）awakeFromNib ，但 - （id）initWithCoder：（NSCoder *）aDecoder 和 - （id）awakeAfterUsingCoder：（NSCoder *）aDecoder 不是。

In MyCustomView.xib, I set the Class to MyCustomView as well. In MyCustomView.m, - (void)awakeFromNib is called, but - (id)initWithCoder:(NSCoder *)aDecoder and - (id) awakeAfterUsingCoder:(NSCoder*)aDecoder aren't.

我想要什么要实现的是，在我的ViewController中，我添加的视图被填充了我在MyCustomView.xib中设置的视图。最好的方法是什么？

What I'd like to achieve is that in my ViewController, the view I added is "filled" with the view I set up in MyCustomView.xib. What's the best way to do that?

编辑：我认为我不够清楚......

我的ViewController包含一个名为MyCustomView的自定义视图。

I've got my ViewController containing a Custom View called MyCustomView.

此视图应为MyCustomView类型，其中

This view should be of type MyCustomView, where

MyCustomView.h
MyCustomView.m
MyCustomView.xib

MyCustomView.hMyCustomView.mMyCustomView.xib

存在。我已经将MyCustomView.xib的文件所有者设置为MyCustomView，我已经将ViewController中的CustomView设置为MyCustomView - 但它不起作用。

exists. I already set the File's Owner of MyCustomView.xib to MyCustomView and I already set the CustomView in my ViewController to MyCustomView - but it doesn't work.

如果我这样做with

If I do it with

- (void)awakeFromNib {
    NSString* nibName = NSStringFromClass([self class]);
    NSArray* topLevelObjects;
    [[NSBundle mainBundle] loadNibNamed:nibName
                              owner:nil
                    topLevelObjects:&topLevelObjects];

    NSView* view = topLevelObjects[0];
    [view setFrame:[self bounds]];
    [self addSubview:view];
}

我只获得NSView类型的视图，而不是MyCustomView ...是否存在没有简单的方法告诉ViewController.xib它是一个MyCustomView？

I only get a view of type NSView, not MyCustomView... Is there no easy way to tell the ViewController.xib that it's a MyCustomView?

编辑2：我上传了一个简单的项目

在你找到一个带MyCustomView的简单项目（不是在ViewController中，而是在window.xib中） - 但是它没有显示MyCustomView.xib中的按钮。我想要实现这一点 - 最简单，最好的方式是什么？

At https://dl.dropboxusercontent.com/u/119600/Testproject.zip you find a simple project with the MyCustomView (not in a ViewController but in the window.xib) - but it doesn't show the button which is in MyCustomView.xib. I'd like to achieve exactly that - what's the simplest, best way?

推荐答案

编辑 - 道歉，我现有的答案没有考虑到连接出口和行动的必要性。这种方式应该这样做...

EDIT - apologies, my existing answer failed to take into account the need to connect outlets and actions. This way should do it...

给定文件......

Given the files...

MyCustomView.h
MyCustomView.m
MyCustomView.xib

In MyCustomView.h

为您的界面元素声明IBOutlets。您至少需要一个，指向xib文件中顶级视图的指针

declare IBOutlets for your interface elements. You need at least one, to hold a pointer to the top-level view in the xib file

@property（非原子，强）IBOutlet NSView *查看;

在MyCustomView.xib中

In MyCustomView.xib

确保在Identity Inspector中只有一个顶级视图

将文件的所有者类设置为MyCustomView

确保顶级视图设置为默认 NSView 类。

现在您可以连接声明的IBOutlets在MyCustomView.h中接口xib文件中的对象。至少您需要将顶级视图连接到视图插座。

ensure that there is only one top-level view
set file's owner class to MyCustomView in the Identity Inspector
ensure that the top-level view is set to the default NSView class.
now you can connect IBOutlets declared in MyCustomView.h to interface objects in the xib file. At very least you need to connect up the top-level view to your view outlet.

在MyCustomView.m中：

In MyCustomView.m:

- (id)initWithFrame:(NSRect)frame
{
    NSString* nibName = NSStringFromClass([self class]);
    self = [super initWithFrame:frame];
    if (self) {
        if ([[NSBundle mainBundle] loadNibNamed:nibName
                                          owner:self
                                topLevelObjects:nil]) {
            [self.view setFrame:[self bounds]];
            [self addSubview:self.view];
            [self.myCustomButton setTitle:@"test success"];
        }
    }
    return self;
}

在窗口的xib文件中，添加自定义NSView并将其类更改为MyCustomView 。

In your window's xib file, add a custom NSView and change it's class to MyCustomView.

在OSX 10.8之前的方法 loadNibNamed 是一个类方法 - 如果你需要向后兼容，请使用它，但现在已弃用：

in OSX prior to 10.8 the method loadNibNamed was a class method - use it instead if you need backwards compatibility, but it is deprecated now:

[NSBundle loadNibNamed:@"NibView" owner:self]

请注意，MyCustomView.xib的视图是 NOT MyCustomView的视图，但它是视图的唯一子视图（这是类似于tableViewCell拥有单个contentView的方式。）

Note that MyCustomView.xib's view is NOT MyCustomView's view, but the sole subview of it's view (this is similar to the way a tableViewCell possesses a single contentView).

在您发布的项目示例中，您需要进行以下更改：

In the project sample you have posted, you need to make the following changes:

在MyCustomView.h中

。在MyCustomView.xib中添加NSView属性

in MyCustomView.h
. add an NSView property

：

。将顶级视图从 MyCustomView 自定义类更改为 NSView （默认值）

。将文件所有者设置为 MyCustomView 。

。将IBOutlets从File的所有者的视图和 myCustomButton 连接到界面视图和按钮

。用于测试使视图更小并将按钮向上推到右上方（您将不会在窗口中看到它，因为它在这里）

in MyCustomView.xib:
. change the top-level view from MyCustomView custom class to NSView (the default)
. set the File's Owner to MyCustomView.
. connect IBOutlets from File's owner's view and myCustomButton to interface view and button
. for testing make the view a lot smaller and push the button up to the top right (you won't see it in your window as it is here)

在MyCustomView.m中：

。用 initWithFrame 方法替换所有实现代码

in MyCustomView.m:
. replace all of your implementation code with the initWithFrame method here
