设置 iPhone 应用程序导航栏中 2 个按钮的色调颜色
我在 IB 中创建了一个 UINavigationBar。但没有看到任何设置按钮颜色的方法...所以我用代码执行此操作：
for(id subView in navBar.subviews)
if( [subView isKindOfClass:[UIButton class]] )
{
UIBarButtonItem *b = (UIBarButtonItem *)subView;
if( [b.title isEqualToString:@"Cancel"] ) [b setTintColor:[UIColor redColor]];
if( [b.title isEqualToString:@"Save" ] ) [b setTintColor:[UIColor greenColor]];
}
它似乎有效...但给出了 2 个关于它不响应 setTintColor 的警告。
有没有更好的（并且完全合法的）方法来做到这一点？
I've created a UINavigationBar in IB. But don't see any way to set the button colors... so I do this with code:
for(id subView in navBar.subviews)
if( [subView isKindOfClass:[UIButton class]] )
{
UIBarButtonItem *b = (UIBarButtonItem *)subView;
if( [b.title isEqualToString:@"Cancel"] ) [b setTintColor:[UIColor redColor]];
if( [b.title isEqualToString:@"Save" ] ) [b setTintColor:[UIColor greenColor]];
}
It appears to work... but gives 2 warnings about it not responding to setTintColor.
Is there a better (and fully legal) way to do that?
