在iOS 7中,苹果增加了一个新的默认导航行为。你可以从屏幕的左边缘滑动回到导航堆栈。但在我的应用程序中,这种行为与我的自定义左侧菜单冲突。那么,是否有可能在UINavigationController中禁用这个新手势?
当前回答
我发现只把手势设置为禁用并不总是有效。它确实有用,但对我来说,只有在我用过一次后才起作用。第二次就不会触发手势了。
修复我是委托手势和实现shouldbegin方法返回NO:
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
// Disable iOS 7 back gesture
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
self.navigationController.interactivePopGestureRecognizer.delegate = self;
}
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
// Enable iOS 7 back gesture
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
self.navigationController.interactivePopGestureRecognizer.delegate = nil;
}
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
return NO;
}

迅速:
navigationController!.interactivePopGestureRecognizer!.enabled = false
我的方法。一个手势识别器来统治它们:
class DisabledGestureViewController: UIViewController: UIGestureRecognizerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
navigationController!.interactivePopGestureRecognizer!.delegate = self
}
func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
// Prevent going back to the previous view
return !(navigationController!.topViewController is DisabledGestureViewController)
}
}
重要:不要在导航堆栈的任何地方重置委托:navigationController!.interactivePopGestureRecognizer!.delegate = nil
它适用于我的ios 10和更高版本:
- (void)viewWillAppear:(BOOL)animated {
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
}
它在viewDidLoad()方法上不起作用。
没有一个给出的答案帮助我解决这个问题。在这里张贴我的答案;可能对某人有帮助
声明私有var popGesture: UIGestureRecognizer?作为视图控制器中的全局变量。然后在viewDidAppear和viewWillDisappear方法中实现代码
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
if self.navigationController!.respondsToSelector(Selector("interactivePopGestureRecognizer")) {
self.popGesture = navigationController!.interactivePopGestureRecognizer
self.navigationController!.view.removeGestureRecognizer(navigationController!.interactivePopGestureRecognizer!)
}
}
override func viewWillDisappear(animated: Bool) {
super.viewWillDisappear(animated)
if self.popGesture != nil {
navigationController!.view.addGestureRecognizer(self.popGesture!)
}
}
这将禁用滑动回iosv8。x起
请在root vc下设置:
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:YES];
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
-(void)viewDidDisappear:(BOOL)animated{
[super viewDidDisappear:YES];
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}
