//隐藏返回按钮的后的文字
[[UIBarButtonItemappearance]setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -600)
forBarMetrics:UIBarMetricsDefault];
// self.navigationBar.barTintColor=[UIColor whiteColor];
//设置返回按钮为白色
self.navigationBar.tintColor=[UIColorwhiteColor];
self.navigationBar.translucent=NO;
//透明导航栏
// [self.navigationBar setBackgroundImage:[UIImage new]
// forBarMetrics:UIBarMetricsDefault];
// self.navigationBar.shadowImage = [UIImage new];

UIImage*backButtonImage = [[UIImageimageNamed:@"icon_back"]resizableImageWithCapInsets:UIEdgeInsetsMake(0,30,0,0)];
[[UIBarButtonItemappearance]setBackButtonBackgroundImage:backButtonImageforState:UIControlStateNormalbarMetrics:UIBarMetricsDefault];
//将返回按钮的文字position设置不在屏幕上显示
[[UIBarButtonItemappearance]setBackButtonTitlePositionAdjustment:UIOffsetMake(NSIntegerMin,NSIntegerMin)forBarMetrics:UIBarMetricsDefault];
