隐藏导航栏下的黑线

有些时候需要隐藏导航栏的黑线,使导航栏可以和下面的view看起来好像一体

-(void)viewDidLoad {

[self enumerationSubView:self.navigationController.navigationBar.subviews];

}

- (void)enumerationSubView:(NSArray *)array {

for (UIView *view in array) {

if (view.bounds.size.height <= 1) {

[view removeFromSuperview];

break;

} else {

[self enumerationSubView:view.subviews];

}

}

}
