设置导航栏的相关属性

很多其它具体内容请參考http://www.cocoachina.com/applenews/devnews/2013/1104/7287.html

别人的代码敲一遍就成了自己的了

//改动导航栏的背景色
    [[UINavigationBar appearance] setBarTintColor:[UIColor yellowColor]];
    //设置导航栏的背景图片。
    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"Icon.png"] forBarMetrics:UIBarMetricsDefault];
    //设置导航button的颜色
    [[UINavigationBar appearance] setTintColor:[UIColor greenColor]];
    //设置导航栏button图片
    [[UINavigationBar appearance]setBackIndicatorTransitionMaskImage:[UIImage imageNamed:@"Icon.png"]];
    [[UINavigationBar appearance] setBackIndicatorImage:[UIImage imageNamed:@"Icon.png"]];
    //设置导航栏标题的字体
    NSShadow *shadow = [[NSShadow alloc] init];
    shadow.shadowColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.8];
    shadow.shadowOffset = CGSizeMake(0, 1);
    [[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:240.0/255.0 alpha:1],NSForegroundColorAttributeName,shadow,NSShadowAttributeName,[UIFont fontWithName:@ "HelveticaNeue-CondensedBlack"  size:21.0], NSFontAttributeName, nil]];
    //设置导航栏的标题为图片 在各个控制器下调用
     //self.navigationItem.titleView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"Icon.png"]];

设置全局隐藏状态栏

在.plist文件里加入这两个属性
