Why am I getting a deprecated warning in XCode
提问by AngryHacker
I am getting a warning about setText method when I am not even using it. Why does XCode display this warning message?
我什至不使用 setText 方法时，都会收到有关它的警告。为什么 XCode 会显示此警告消息？

The cell.textproperty is deprecated in iPhone OS 3.0 and greater, because new table cell types allow multiple labels. Instead, use cell.textLabel.textto accomplish the same thing.
该cell.text属性在 iPhone OS 3.0 及更高版本中已弃用，因为新的表格单元格类型允许使用多个标签。相反，用于cell.textLabel.text完成相同的事情。

this is how properties work
这就是属性的工作方式
x = object.fieldis (by default) the same as calling x = [object field]
x = object.field（默认情况下）与调用相同 x = [object field]
and object.field = xis (by default) the same as calling [object setField:x]
并且object.field = x（默认情况下）与调用相同[object setField:x]

The up two answers are more than correct. Just to add some references from Apple's Dev. Believe that will solve all of your questions. Please take a look at the session for "Object Messaging"
以上两个答案都非常正确。只是添加一些来自 Apple 开发人员的参考。相信这会解决你所有的问题。请看一看“对象消息传递”的会话

By setting a class's field the way you are, you are actually calling the setText method
通过按照您的方式设置类的字段，您实际上是在调用 setText 方法
