我创建了自己的UINavigationBar子类,以便启用高于44pxs的自定义背景。
I created my own subclass of UINavigationBar in order to enable custom background that is taller than 44pxs.
我是通过覆盖这两种方法来实现的:
I did it by overriding these two methods:
-(void) drawRect:(CGRect)rect { [self.backgroundImage drawInRect:CGRectMake(0, 0, self.backgroundImage.size.width, self.backgroundImage.size.height)]; } - (CGSize)sizeThatFits:(CGSize)size { CGRect frame = [UIScreen mainScreen].applicationFrame; CGSize newSize = CGSizeMake(frame.size.width , self.backgroundImage.size.height); return newSize; }这就是结果:
现在,我可以看到的问题是所有UIBarButtonItem(和titleView)都放在导航栏的底部。
Now, my problem as you can see is that all the UIBarButtonItem's (and the titleView) are placed at the bottom of the navigation bar.
我希望它们是固定在栏的顶部(当然有一些填充)。 为了达到这个目的,我需要覆盖什么?
I would like them to be pinned to the top of the bar (with some padding of course). What to I need to override to achieve that?
谢谢!
编辑:
这是我使用的解决方案:
This is the solution that I used:
-(void) layoutSubviews { [super layoutSubviews]; for (UIView *view in self.subviews) { CGRect frame = view.frame; frame.origin.y = 5; view.frame = frame; } }空闲状态的诀窍,还是有些奇怪推送和弹出项目的行为。
Does the trick for idle state, still have some weird behavior on push and pop items.
推荐答案尝试覆盖 layoutSubviews :在里面调用 [super layoutSubviews] ,然后重新定位项目。
Try to override layoutSubviews: call [super layoutSubviews] inside and then reposition the items.
