方法一：

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    if([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
    }
}

- (void)viewDidDisappear:(BOOL
 
)animated {
    [super viewDidDisappear:animated];
    //在其他離開改頁面的方法同樣加上下面程式碼
    if([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
    }
}

方法二

- (void)viewDidAppear:(BOOL
 
)animated {
  [superviewDidAppear:animated];
  self.isCanSideBack = NO;
if([self.navigationControllerrespondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.delegate=self;
}
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer)gestureRecognizer {
    return
 
 self.isCanSideBack;
}
- (void)viewDidDisappear:(BOOL)animated {
[superviewDidDisappear:animated];
//在其他離開改頁面的方法同樣加上下面兩句程式碼
self.isCanSideBack=YES;
if([self.navigationControllerrespondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.delegate = nil;
}
}

注：如果呼叫了popToRootViewControllerAnimated，不會走viewDidDisappear。所以需要在返回的方法裡面加上相應程式碼，以便其他頁面支援側滑返回
