为什么我在XCode中收到过时的警告

Question

I am getting a warning about setText method when I am not even using it. Why does XCode display this warning message?

Answer 1

The cell.text property is deprecated in iPhone OS 3.0 and greater, because new table cell types allow multiple labels. Instead, use cell.textLabel.text to accomplish the same thing.

Answer 2

this is how properties work

x = object.field is (by default) the same as calling x = [object field]

and object.field = x is (by default) the same as calling [object setField:x]

Answer 3

Answer 4

通过按原样设置类的字段，实际上是在调用setText方法
