Cocoa:当它在NSButton上时更改光标

Question

当它在NSButton上时,如何更改光标？

Answer 1

您应该首先继承NSButton,然后添加下面的代码.

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

现在您可以根据需要设置光标.

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

注意:添加cursor为子类的属性,如下所示:

@property (strong) NSCursor *cursor;  

Answer 2

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