Ios 选项卡栏项目的自定义图像

更改UITabBar项目的自定义图像 我用过这个代码，但它不起作用

UIImage *selectedImage0 = [UIImage imageNamed:@"f.png"];
UIImage *unselectedImage0 = [UIImage imageNamed:@"f.png"];

UIImage *selectedImage1 = [UIImage imageNamed:@"g.png"];
UIImage *unselectedImage1 = [UIImage imageNamed:@"g.png"];

UIImage *selectedImage2 = [UIImage imageNamed:@"i.png"];
UIImage *unselectedImage2 = [UIImage imageNamed:@"i.png"];

UIImage *selectedImage3 = [UIImage imageNamed:@"s.png"];
UIImage *unselectedImage3 = [UIImage imageNamed:@"s.png"];

UIImage *selectedImage4 = [UIImage imageNamed:@"t.png"];
UIImage *unselectedImage4 = [UIImage imageNamed:@"t.png"];


UITabBar *tabBar = self.tabBarController.tabBar;
UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
UITabBarItem *item3 = [tabBar.items objectAtIndex:3];
UITabBarItem *item4 = [tabBar.items objectAtIndex:4];

[item0 setFinishedSelectedImage:selectedImage0 withFinishedUnselectedImage:unselectedImage0];
[item1 setFinishedSelectedImage:selectedImage1 withFinishedUnselectedImage:unselectedImage1];
[item2 setFinishedSelectedImage:selectedImage2 withFinishedUnselectedImage:unselectedImage2];
[item3 setFinishedSelectedImage:selectedImage3 withFinishedUnselectedImage:unselectedImage3];
[item4 setFinishedSelectedImage:selectedImage4 withFinishedUnselectedImage:unselectedImage4];

您应该使用

-（UIImage*）图像和渲染模式：（UIImageRenderingMode）渲染模式NS\u可用的IOS（7\u 0）方法如下

item0.image = [unselectedImage1 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
item0.selectedImage = [selectedImage1 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

您已经为每个选项卡项简单图像和悬停图像设置了两个图像

item0.image = [[UIImage imageNamed:@"f.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; // set simple image

item0.selectedImage = [[UIImage imageNamed:@"f.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; // set hover image

不。我有自己的答案，但上传答案时出现问题。在更新我的答案之前，您已经回答了。。
