設定導航欄的返回按鈕以及文字

1、新建一個類（MPSNavigationController）繼承至 UINavigationController。

2、

- (void)viewDidLoad {
    [super viewDidLoad];
    [self configTitleTextStyle];
    
    self.view.backgroundColor = [UIColor whiteColor];//背景色
    if ([self.navigationBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics: )]) {//設定返回按鈕樣式。這裡是自定義的圖片
        UIImage *image = [UIImage imageNamed:@"icon_back"];
        image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        self.navigationBar.backIndicatorImage = image;
        self.navigationBar.backIndicatorTransitionMaskImage = image;
    }
}

/**
 *  設定導航上的title顯示樣式，白色文字
 */
-(void)configTitleTextStyle{
    NSShadow *shadow = [[NSShadow alloc] init];
    shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
    shadow.shadowOffset = CGSizeMake(0, 0);
    UIColor *textColor = [UIColor blackColor];
    [self.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                textColor, NSForegroundColorAttributeName,shadow, NSShadowAttributeName,[UIFont fontWithName:@"PingFang SC" size:18.0f], NSFontAttributeName,
                                                nil]];
}

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated//判斷如果不是根控制器的話退出的介面自動隱藏底部tabbar
{
    if (self.childViewControllers.count) { // 不是根控制器
        
        viewController.hidesBottomBarWhenPushed = YES;
        
    }
    
    [super pushViewController:viewController animated:animated];
}

歡迎
