标签栏项目是一个灰色正方形 [英] Tab Bar Item is a grey square

问题描述

如您所见，没有图像，只有一个大的灰色方块.我的资产目录中有一个图像，并且已经通过属性检查器对其进行了设置.图片为50x50px，我在文档中读到它可以是任何大小，但不能大于96x96.下面的屏幕截图.

As you can see, instead of an image there is just a big grey square. I have an image in my asset-catalog and I've set it through the attributes inspector. The image is 50x50px, and I read in documentation that it could be of any size but not bigger than 96x96. Screenshot below.

谢谢！

推荐答案

iOS7中存在错误，未选中的选项卡栏项始终为灰色.

There is bug in iOS7 and the unselected tab bar item is always with grey tint color.

尝试以下操作:(添加到AppDelegate应用程序中:didFinishLaunchingWithOptions:)

Try this: (add in AppDelegate application:didFinishLaunchingWithOptions:)

    UITabBarItem *item1 = self.tabBarController.tabBar.items[0];
    item1.image = [[UIImage imageNamed:@"tabbar-item1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; // unselected image
    item1.selectedImage = [UIImage imageNamed:@"tabbar-item1-selected"]; // selected image

    UITabBarItem *item2 ...
    ...
