Objective-c - What does the syntax getter assignment syntax mean when defining properties in iOS?

Question

When defining properties on iOS @property (assign, nonatomic, getter=isDidSelected) BOOL didSelected; What does getter=isDidSelected mean? After the Demo I downloaded was written like this, the attribute isDidSelected was no longer defined.

Answer 1

To put it bluntly, it’s just to change the name of the get method

If you don’t write getter=isDidSelected, then the get method of Boolean value didSelected is didSelected. You can

- (BOOL) didSelected { 
return didSelected; 
}

Come and rewrite it. Use together

self. didSelected

Come and get it.
