iOS 导航栏无缝圆滑的隐藏 Navigationbar实例代码

1.VieController

.m

- (void)vieDidLoad {
 [super vieDidLoad];
 self.title = @"隐藏导航栏";
 UIButton button = [UIButton buttonWithType:UIButtonTypeCustom];
 button.backgroundColor = [UIColor lightGrayColor];
 button.frame = CGRectMake(10, 100, 60, 30);
 [button addTarget:self action:@selector(buttonClick) forControlEvents:UIControlEventTouchUpInside];
 [self.vie addSubvie:button];
 self.navigationController.delegate = self;
}
- (void)buttonClick{
 ///跳转到KKVieController
 [self performSegueWithIdentifier:@"pusht" sender:nil];
}

头部代理

@interface VieController ()

代理方法

- (void)navigationController:(UINavigationController )navigationController illShoVieController:(UIVieController )vieController animated:(BOOL)animated {
 [self.navigationController setNavigationBarHidden: [self hiddenBarVc: vieController] animated: animated];
}
- (BOOL)hiddenBarVc:(UIVieController )vieController {
 BOOL needHideNaivgaionBar = NO;
 if ([vieController isKindOfClass: [KKVieController class]]) {
 needHideNaivgaionBar = YES;
 }
 return needHideNaivgaionBar;
}

2.KKVieController（目标VieController）

新建一个KKVieController

.h

@property (nonatomic,strong) id popDelegate;

.m

- (void)vieDidLoad {
 [super vieDidLoad];
 self.title = @"第二个页面";
 [self popSet];
}
- (void)popSet{
 _popDelegate = self.navigationController.interactivePopGestureRecognizer.delegate;
 SEL action = NSSelectorFromString(@"handleNavigationTransition:");
 UIPanGestureRecognizer popPanGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self.popDelegate action:action];
 popPanGesture.maximumNumberOfTouches = 1;
 popPanGesture.delegate = self;
 [self.vie addGestureRecognizer: popPanGesture];
}

头部代理

@interface KKVieController ()

手势代理方法

- (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer )gestureRecognizer{
 ///【下面两个方法写一个】
 ///全屏拖动
 CGPoint tragPoint = [gestureRecognizer translationInVie:gestureRecognizer.vie];
 if (tragPoint.x <= 0){
  return NO;
 }
 else{
  if (self.navigationController.vieControllers.count <= 1){
   return NO;
  }
  else{
   return YES;
  }
 }
// ///局部允许拖动
// CGPoint tragPoint = [gestureRecognizer locationInVie:gestureRecognizer.vie];
// NSLog(@"x=%f;y=%f",tragPoint.x,tragPoint.y);
// if (tragPoint.x > 60){///拖动的范围
//  return NO;
// }
// else{
//  if (self.navigationController.vieControllers.count <= 1) {
//   return NO;
//  }
//  else{
//   return YES;
//  }
// }
}
