我创建了这样的自定义导航按钮:
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"some.png"] forState:UIControlStateNormal];
....
[[current navigationItem] setLeftBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:button]];
当前是 UIViewController * 类型。一切正常并创建了按钮,但它是按钮外部的可点击区域,非常靠近导航栏的中间。是否可以限制可点击区域?
