如何使财产成为财产 [英] How to make a property of a property

问题描述

我不太确定如何表达这个问题，因此我将举例说明.我想为一个财产做一个财产.我目前正在使用其他类别的属性:

I'm not quite sure how to word this question, so I'll show examples. I want to make a property for a property. I am currently using a property from a different class:

player = [[Player alloc] init];
player.name = @"PlayerName";

这些属性在Player类中定义，并导入Player.h.

These properties are defined in the Player class, and Player.h is imported.

我想为.name提供一个子属性"，所以它看起来像player.name.newProperty. UILabel就是一个例子:

I want to have a 'sub-property' for .name, so it will look like player.name.newProperty. An example of this is for UILabel:

labelName = [[UILabel alloc] init];
self.labelName.text = @"String"; // .text being the 'sub-property'

推荐答案

现在，player.name是NSString

如果您将其设为自定义类(而不是NSString)，并具有其自己的属性，则可以将其作为子属性"来访问

If instead of an NSString, you make it a custom class, with it's own properties, you will be able to access them as "sub-properties"

player.name = [[MyCustomObject alloc] init];
player.name.subProperty = @"value";

请记住，您将需要为MyCustomObject创建适当的.m和.h文件并定义其属性.

Keep in mind, you will need to create the appropriate .m and .h files for MyCustomObject and define its properties.
