隐藏导航栏底部的线条
转载：https://www.jianshu.com/p/aa547432eae0
方法1 (单页面设置)
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
如果不想影响其他页面的导航透明度，viewWillDisappear将其设置为nil即可:
[self.navigationController.navigationBar setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setShadowImage:nil];
方法2(全局设置)
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];
方法3
self.navigationController.navigationBar.clipsToBounds = YES;
设置导航栏底部线条颜色的代码：
UINavigationBar *navigationBar = self.navigationController.navigationBar;
[navigationBar setBackgroundImage:[[UIImage alloc] init] forBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault]; //此处使底部线条颜色为红色
[navigationBar setShadowImage:[UIImage imageWithColor:[UIColor redColor]]];
@implementation UIImage (ColorImage)
+ (UIImage *)imageWithColor:(UIColor *)color{
CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext(); return image;
}@end
修复navigationController侧滑关闭失效的问题
self.navigationController.interactivePopGestureRecognizer.delegate = (id)self
隐藏返回按钮后面的文字
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60)
forBarMetrics:UIBarMetricsDefault];
