自定义 UINavigationController UINavigationBar

问题描述

基本上我想要一个自定义 UINavigationBar.我不希望它是半透明的"或任何东西，比如图片应用.

Basically I want a custom UINavigationBar. I don't want it to be "translucent" or anything, like the pictures app.

我基本上想完全删除它，但我仍然希望能够在推送导航控制器时添加后退按钮等，并且我希望推送视图(EG:UITableViewController)在它下面.

I basically want to completely remove it, but I still want to be able to add back buttons and such when navigation controllers are pushed, and I want the views (EG: UITableViewController) to be pushed down below it.

像这样:

任何想法如何实现这一点?

Any ideas how to achieve this at all?

谢谢

推荐答案

@implementation UINavigationBar (background)

- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed:@"navigationbar.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}

@end

基本上，它并不能完全看穿 - 这是一个视觉谎言.实际做到这一点的唯一方法是重写 UINavigationBar 的 drawRect: 方法，如上所示.

basically, its not completely see through - its a visual lie. The only way to do it realistically is to override UINavigationBar's drawRect: method, as shown above.
