我必须在TabBar的部分之间添加分隔符,如下图所示：
我试图设置背景iamge为tabbar使用这个图像：
但是当我旋转设备时我有问题.
我使用的代码：
+ (UITabBarController *)loadTabbar
{
UITabBarController *tabBarController = [UITabBarController new];
MenuVC *viewController0 = [MenuVC new];
FavVC *viewController1 = [FavVC new];
UploadVC *viewController2 = [UploadVC new];
RestoreVC *viewController3 = [RestoreVC new];
SettingsVC *viewController4 = [SettingsVC new];
tabBarController.viewControllers = @[viewController0,viewController1,iewController2,viewController3,viewController4];
[tabBarController.tabBar setBackgroundImage:[UIImage mageNamed:@"tabbar_color"]];
[self setRootController:tabBarController];
return tabBarController;
}
此外,我尝试在图像的右侧添加一个分隔符,我用于abbar项,但没有结果.
请问,请帮帮我吗？
谢谢 ！
解决方法
您可以通过编程方式使UITabBar的背景：
#define SEPARATOR_WIDTH 0.4f
#define SEPARATOR_COLOR [UIColor whiteColor]
- (void) setupTabBarSeparators {
CGFloat itemWidth = floor(self.tabBar.frame.size.width/self.tabBar.items.count);
UIView *bgView = [[UIView alloc] initWithFrame:CGRectMake(0,self.tabBar.frame.size.width,self.tabBar.frame.size.height)];
for (int i=0; i<self.tabBar.items.count - 1; i++) {
UIView *separator = [[UIView alloc] initWithFrame:CGRectMake(itemWidth * (i +1) - SEPARATOR_WIDTH/2,SEPARATOR_WIDTH,self.tabBar.frame.size.height)];
[separator setBackgroundColor:SEPARATOR_COLOR];
[bgView addSubview:separator];
}
UIGraphicsBeginImageContext(bgView.bounds.size);
[bgView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *tabBarBackground = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[[UITabBar appearance] setBackgroundImage:tabBarBackground];
}
您应该只扩展UITabBarController并制作一个自定义的UITabBarViewController.您应该在viewDidLoad和willRotateToInterfaceOrientation中调用此方法.
