设置导航栏透明

怎么把我的navigationbar弄成透明的而不是带模糊的效果？ [self.navigationBar setBackgroundImage:[UIImage new]   forBarMetrics:UIBarMetricsDefault];   self.navigationBar.shadowImage = [UIImage new];   self.navigationBar.translucent = YES;

设置导航栏透明

#pragma mark -

视图将要出现
- (void)viewWillAppear:(BOOL)animated

{

    [super

viewWillAppear:animated];

   
//导航栏背景

    [self.navigationController.navigationBar

setBackgroundImage:[UIImage

imageNamed:@"nav_bargound.png"]

forBarMetrics:UIBarMetricsDefault];

   

   
//导航栏底部线

   
self.navigationController.navigationBar.shadowImage
=[UIImage

imageNamed:@"nav_bargound.png"];

}
#pragma mark -

视图将要消失
- (void)viewWillDisappear:(BOOL)animated

{

    [super

viewWillDisappear:animated];

   
//导航栏背景

    [self.navigationController.navigationBar

setBackgroundImage:nil

forBarMetrics:UIBarMetricsDefault];

   

   
//导航栏底部线

   
self.navigationController.navigationBar.shadowImage
=[UIImage

imageNamed:@""];

}
