IOS：禁止页面上的侧滑返回手势

建立UIViewController的分类，加上如下两个方法

@implementation UIViewController (UIViewC)
+ (void)popGestureClose:(UIViewController *)VC
{
    // 禁用侧滑返回手势
    if ([VC.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        //这里对添加到右滑视图上的所有手势禁用
        for (UIGestureRecognizer *popGesture in VC.navigationController.interactivePopGestureRecognizer.view.gestureRecognizers) {
            popGesture.enabled = NO;
        }
        //若开启全屏右滑，不能再使用下面方法，请对数组进行处理
        //VC.navigationController.interactivePopGestureRecognizer.enabled = NO;
    }
}
+ (void)popGestureOpen:(UIViewController *)VC
{
    // 启用侧滑返回手势
    if ([VC.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
    //这里对添加到右滑视图上的所有手势启用
        for (UIGestureRecognizer *popGesture in VC.navigationController.interactivePopGestureRecognizer.view.gestureRecognizers) {
            popGesture.enabled = YES;
        }
        //若开启全屏右滑，不能再使用下面方法，请对数组进行处理
        //VC.navigationController.interactivePopGestureRecognizer.enabled = YES;
    }
}

然后在页面上进行方法的开启与关闭

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [UIViewController popGestureClose:self];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [UIViewController popGestureOpen:self];
}

这个离开时开启手势，如果没有生效，可以在离开后的第一个界面导入分类，然后在类一开始加上开启手势的语句。
