objective-c - 单击UINavigationBar按钮时的光泽效果

Question

当我单击UIButton顶部的UINavigationBar时，我会得到如下光泽效果:

如何将此效果添加到UINavigatonBar上的另一个按钮上，而不添加为左按钮或右按钮项目？像这样:

UIButton * emptyButton = [UIButton buttonWithType:UIButtonTypeCustom];
[emptyButton setFrame:CGRectMake(119, 5, 82, 35)];
[emptyButton addTarget:self action:@selector(centerNavigationBarTitleClicked:) forControlEvents:UIControlEventTouchUpInside];
[emptyButton setBackgroundColor:[UIColor clearColor]];

[self.navigationController.navigationBar addSubview:emptyButton];

谢谢!

您只需将showsTouchWhenHighlighted属性设置为YES即可获得发光效果，即

emptyButton.showsTouchWhenHighlighted = YES;
