UINavigationBar自定义导航栏背景和按钮，完美支持横屏竖屏旋转，视图控制器可以分别使用自己的导航栏
导航上的按钮背景需要做，否则看起来不那么和之又谐
Objective-c代码
1 //CustomNavigationBar.h
2 @interface UINavigationBar (UINavigationBarCategory)
3 UIImageView *
backgroundView;
4 - (
void)setBackgroundImage:(UIImage*
)image;
5 - (
void)insertSubview:(UIView *
)view atIndex:(NSInteger)index;
6 @end
7
8 //CustomNavigationBar.m
9 @implementation UINavigationBar (UINavigationBarCategory)
10 -(
void)setBackgroundImage:(UIImage*
)image
11 {
12 if(image ==
nil)
13 {
14 [backgroundView removeFromSuperview];
15 }
16 else
17 {
18 backgroundView =
[[UIImageView alloc] initWithImage:image];
19 backgroundView.tag =
1;
20 backgroundView.frame = CGRectMake(
0.f,
0.f, self.frame.size.width, self.frame.size.height);
21 backgroundView.autoresizingMask = UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleHeight;
22 [self addSubview:backgroundView];
23 [self sendSubviewToBack:backgroundView];
24 [backgroundView release];
25 }
26 }

28 //for other views
29 - (
void)insertSubview:(UIView *
)view atIndex:(NSInteger)index
30 {
31 [super insertSubview:view atIndex:index];
32 [self sendSubviewToBack:backgroundView];
33 }
34 @end
35
36 //YourViewController.m
37 - (
void)viewWillAppear:(BOOL)animated
38 {
39 [super viewWillAppear:animated];
40 [self.navigationController.navigationBar
41 setBackgroundImage:[UIImage imageNamed:
@"navigation_bar_bg.png"]];
