UINavigationController

-(void)resetTabbarController:(UITabBarController *)controller {

    NSArray *arr = controller.tabBar.items;

    

    UITabBarItem *item0 = [arr objectAtIndex:0];

　　//使用指定图片

    [item0 setSelectedImage:[[UIImage imageNamed:@"icon_everyday_press"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    [item0 setImage:[[UIImage imageNamed:@"icon_everyday"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    

    UITabBarItem *item1 = [arr objectAtIndex:1];

    [item1 setSelectedImage:[[UIImage imageNamed:@"icon_order_press"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    [item1 setImage:[[UIImage imageNamed:@"icon_order_normal"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    

    UITabBarItem *item2 = [arr objectAtIndex:2];

    [item2 setSelectedImage:[[UIImage imageNamed:@"icon_broker_press"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    [item2 setImage:[[UIImage imageNamed:@"icon_broker_normal"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    

    

    UITabBarItem *item3 = [arr objectAtIndex:3];

    [item3 setSelectedImage:[[UIImage imageNamed:@"icon_shop_press"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    [item3 setImage:[[UIImage imageNamed:@"icon_shop_normal"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    

    UITabBarItem *item4 = [arr objectAtIndex:4];

    [item4 setSelectedImage:[[UIImage imageNamed:@"icon_houses_press"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    [item4 setImage:[[UIImage imageNamed:@"icon_houses_normal"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    

    CGRect frame = CGRectMake(0, 0, SCREEN_WIDTH, 49);

　　//修改tabbar颜色

    UIView *v = [[UIView alloc] initWithFrame:frame];

    UIImage *img = [Utility imageWithColor:[UIColor whiteColor]];

    UIColor *color = [[UIColor alloc] initWithPatternImage:img];

    v.backgroundColor = color;

    [controller.tabBar insertSubview:v atIndex:0];

    controller.tabBar.tintColor = ColorBg3;

    //修改tabbaritem文字颜色

    [[UITabBarItem appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor colorWithWhite:0.0 alpha:0.87]} forState:UIControlStateNormal];

    controller.tabBar.barTintColor = [UIColor colorWithWhite:0.0 alpha:0.87];

    controller.tabBar.opaque = NO;

    

//    [controller setSelectedIndex:0];

}

1、UINavigationBar 背景色修改

- (void)viewWillAppear:(BOOL)animated

{

    UINavigationBar *bar = self.navigationController.navigationBar;

    //关键是这几句。。。。。

    [bar setTranslucent:NO];

    

    if (CURRENT_IOS_VERSION >= 7) {

        if ([self.navigationController.navigationBar respondsToSelector:@selector( setBackgroundImage:forBarMetrics:)]){

            [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"bg_title_up"] forBarMetrics:UIBarMetricsDefault];

        }

    }else{

        [bar setBackgroundImage:[Utility imageWithColor:[Utility stringToColor:@"#df4919"]] forBarMetrics:UIBarMetricsDefault];

        [bar.layer setMasksToBounds:YES];

        [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlackOpaque;

    }

    if ([UINavigationBar instancesRespondToSelector:@selector(setShadowImage:)])

    {

        [[UINavigationBar appearance] setShadowImage:[UIImage imageWithColor:[UIColor clearColor] size:CGSizeMake(320, 3)]];

    }    

    [super viewWillAppear:animated];

    //[MobClick beginLogPageView:NSStringFromClass([self class])];

}

2、设置返回按钮

-(void) setShowBackBtn:(BOOL)_showBackBtn

{

    showBackBtn = _showBackBtn;

    

    if (self.navigationController.navigationBarHidden)

    {

        UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

        [btn addTarget:self action:@selector(backAction:) forControlEvents:UIControlEventTouchUpInside];

        UIImage *normalImg = [UIImage imageNamed:@"icon_back_nomal"];

        UIImage *hightLightImg = [UIImage imageNamed:@"icon_back_press"];

        [btn setImage:normalImg forState:UIControlStateNormal];

        [btn setImage:hightLightImg forState:UIControlStateHighlighted];

        [btn  setFrame:CGRectMake(0, 22, 26, 39)];

        [btn setImageEdgeInsets:UIEdgeInsetsMake(10, 5, 10, 10)];

        [self.view addSubview:btn];

    } else {

        if (showBackBtn) {

            UIBarButtonItem *backItem = [UIFactory backItemWithTarget:self selector:@selector(backAction:)];

            if (CURRENT_IOS_VERSION < 7.0) {

                UIBarButtonItem *flexSpacer = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace

                                                                                           target:self

                                                                                           action:nil];

                flexSpacer.width = 10;

                

                [self.navigationItem setLeftBarButtonItems:[NSArray arrayWithObjects:flexSpacer,backItem, nil]];

                [flexSpacer release];

                

            }else{

                [self.navigationItem setLeftBarButtonItem:backItem];

            }

            

        }else{

            self.navigationItem.leftBarButtonItem = nil;

        }

    }

}
