-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated]; //開啟ios右滑返回 if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) { self.navigationController.interactivePopGestureRecognizer.delegate = nil; } } ios自定義返回按鈕
UIBarButtonItem *leftBar = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back_SM"]
style:UIBarButtonItemStylePlain target:self action:@selector(backUpClick) ];
leftBar.tintColor = [UIColor whiteColor];
self.navigationItem.leftBarButtonItem = leftBar;
