使用轻扫手势切换视图控制器
好吧，这是我遇到的问题：
我试图从一个viewController ，我命名MenuViewController其中包含我的菜单（显然）切换。 我有一个名为ViewController的单独的viewController ，它包含我的mapView 。 我希望能够从我的MenuViewController swipe left指滑过我的mapView 。
我不确定从哪里开始。
另外，我正在使用xib文件，而不是故事板。 运行iOS 6
UISwipeGestureRecognizer *swipeLeftGesture=[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGesture:)]; [self.view addGestureRecognizer:swipeLeftGesture]; swipeLeftGesture.direction=UISwipeGestureRecognizerDirectionLeft; -(void)handleSwipeGesture:(UIGestureRecognizer *) sender { NSUInteger touches = sender.numberOfTouches; if (touches == 2) { if (sender.state == UIGestureRecognizerStateEnded) { //Add view controller here } } }
一旦经过这个，
UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleleftSwipe:)]; swipeLeft.numberOfTouchesRequired = 1;//give required num of touches here .. swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft; swipeLeft.delegate = (id)self; [self. view addGestureRecognizer:swipeLeft]; UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handlerightSwipe:)]; swipeRight.numberOfTouchesRequired = 1;//give required num of touches here .. swipeRight.delegate = (id)self; swipeRight.direction = UISwipeGestureRecognizerDirectionRight; [self.view addGestureRecognizer:swipeRight];
现在定义如下的滑动方法：
-(void)handleleftSwipe:(UISwipeGestureRecognizer *)recognizer{ //Do ur code for Push/pop.. } -(void)handlerightSwipe:(UISwipeGestureRecognizer *)recognizer{ //Do ur code for Push/pop.. }
希望它可以帮助你…
尝试这个…
在.h文件中
@interface MenuViewController : UIViewController { ViewController *mapViewObj; }
在.m文件中
-(void) viewDidLoad { [super viewDidLoad]; mapViewObj = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil]; UISwipeGestureRecognizer *swipeLeftGesture=[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGesture:)]; [self.view addGestureRecognizer:swipeLeftGesture]; swipeLeftGesture.direction=UISwipeGestureRecognizerDirectionLeft; } -(void)handleSwipeGesture:(UIGestureRecognizer *) sender { NSUInteger touches = sender.numberOfTouches; if (touches == 2) { if (sender.state == UIGestureRecognizerStateEnded) { //push mapViewObj over here.. [self.navigationController pushViewController:mapViewObj animated:YES]; } } }
这是我为你编码的。
//add gesture recogniser to your view [self addSwipegestureToView:self.view]; - (void) addSwipegestureToView : (UIView *) view{ UISwipeGestureRecognizer *_swipegestureRecogniser = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeGesturePerformed)]; _swipegestureRecogniser.numberOfTouchesRequired = 2; [_swipegestureRecogniser setDirection:UISwipeGestureRecognizerDirectionLeft]; [view addGestureRecognizer:_swipegestureRecogniser]; } - (void) swipeGesturePerformed{ SecondViewController *object = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:object animated:YES]; }
你只需要有currentViewController必须有navigationController适当的推（滑入）导航。
首先，你不能使用内置的导航机制。
你需要将'ViewController'的视图添加到'MenuViewController'视图中，我build议你将'ViewController'作为子视图控制器添加到'MenuViewController'中。
之后，将“ViewController”的框架设置在屏幕的外侧，当您滑动或做手势时，只需将其设置回屏幕即可。
这听起来像是使用UIGestureRecognizer的最佳时机，更具体地说，是使用UISwipeGestureRecognizer
