1.修改tabbar顶部线条
CGRect rect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [[UIColor clearColor] CGColor]);
CGContextFillRect(context, rect);
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[self.tabBar setBackgroundImage:img];
[self.tabBar setShadowImage:img];
[self.tabBar setBackgroundImage:[UIImage imageNamed:@"tabbarbg3.jpg"]];
/////////////如果需要不显示分割线，只需要将下面一句话
[self.tabBar setClipsToBounds:YES];
2.修改navigation底部线条
//先定义属性
@property (nonatomic, strong)UIImageView *contentLineImageView;
//试图出现的时候隐藏
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.contentLineImageView.hidden = YES;
}
//试图消失的时候出现
- (void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
self.contentLineImageView.hidden = NO;
}
//在viewdidload里面调用方法
_contentLineImageView = [self findHairlineImageViewUnder:self.navigationController.navigationBar];
self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
//调用的方法
- (UIImageView *)findHairlineImageViewUnder:(UIView *)view {
if ([view isKindOfClass:UIImageView.class] && view.bounds.size.height <= 1.0) {
return (UIImageView *)view;
}
for (UIView *subview in view.subviews) {
UIImageView *imageView = [self findHairlineImageViewUnder:subview];
if (imageView) {
return imageView;
}
}
