iOS navigationbar 透明

1.     [self.navigationController.navigationBar setTranslucent:YES];  
2. //    为什么要加这个呢，shadowImage 是在ios6.0以后才可用的。但是发现5.0也可以用。不过如果你不判断有没有这个方法，  
3. //    而直接去调用可能会crash，所以判断下。作用：如果你设置了上面那句话，你会发现是透明了。但是会有一个阴影在，下面的方法就是去阴影  
4.     if ([self.navigationController.navigationBar respondsToSelector:@selector(shadowImage)])  
5.     {  
6.         [self.navigationController.navigationBar setShadowImage:[[UIImage alloc] init]];  
7.     }  
8. //    以上面4句是必须的,但是习惯还是加了下面这句话  
9.     [self.navigationController.navigationBar setBackgroundColor:ClearColor];
