ios 禁用系统手势返回功能

在控制器中添加如下代码即可

-(void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
// 禁用返回手势
    dispatch_async(dispatch_get_main_queue(), ^{
        if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
            self.navigationController.interactivePopGestureRecognizer.enabled = NO;
        }
    });
}

-(void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
// 开启返回手势
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
    }
}
