Cocoa: change cursor when it's over an NSButton

问题:

How can I change the cursor when it's over an NSButton?

回答1:

[yourButton addCursorRect:[yourButton bounds] cursor:[theCursorYouWant]]; 

回答2:

You should subclass NSButton first, then add the code below.

- (void)resetCursorRects {     if (self.cursor) {         [self addCursorRect:[self bounds] cursor: self.cursor];     } else {         [super resetCursorRects];     } } 

Now you can set cursor as you like.

[self.button setCursor:[NSCursor pointingHandCursor]]; 

---

Note: add cursor as a property of your subclass, like this:

@property (strong) NSCursor *cursor;   

回答3:

Have the button add a cursor rect.
