UINavigationBar的常用方法

self.view.backgroundColor = [UIColor whiteColor];//设置navigationBar的背景图片

// [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@”map”] forBarMetrics:UIBarMetricsDefault];

//设置背景颜色self.navigationController.navigationBar.barTintColor = [UIColor redColor];//设置状态栏字体颜色/* UIBarStyleDefault          = 0,   //白底,字体黑色 UIBarStyleBlack            = 1,   //黑底,字体白色 UIBarStyleBlackOpaque      = 1, // Deprecated. Use UIBarStyleBlack UIBarStyleBlackTranslucent = 2, // Deprecated. Use UIBarStyleBlack and set the translucent property to YES */self.navigationController.navigationBar.barStyle = UIBarStyleBlack;//设置导航栏是否透明//不透明 UI控件自动下移64self.navigationController.navigationBar.translucent = NO;//不带动画移动navigationBar

// self.navigationController.navigationBarHidden = YES;

//系统默认toolBar是隐藏 //坐标44self.navigationController.toolbarHidden = NO;UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch target:nil action:nil];UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:nil action:nil];UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemTrash target:nil action:nil];//平等分割符号UIBarButtonItem *space = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];space.width = 120;//UIBarButtonSystemItemFlexibleSpace 自动给你算分隔距离,来达到布满屏幕的效果//UIBarButtonSystemItemFixedSpace 固定间距.需要设置withself.toolbarItems = @[item1,space,item2,space,item3];
