自带TabBar选中图片设置问题

设置为UIImageRenderingModeAlwaysOriginal

就会显示出选中状态的图片。当然普通状态的也需要设置。

UINavigationController *nav =({

UINavigationController *controller = [[UINavigationController alloc]initWithRootViewController:rootVC];

[controller.tabBarItem setTitle:title];

UIImage *selectImage = ({

UIImage *image = [UIImage imageNamed:selectString];

UIImageRenderingModeAutomatic,          // Use the default rendering mode for the context where the image is used

UIImageRenderingModeAlwaysOriginal,     // Always draw the original image, without treating it as a template

UIImageRenderingModeAlwaysTemplate,     // Always draw the image as a template image, ignoring its color

image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

image;

});

[controller.tabBarItem setSelectedImage:selectImage];

[controller.tabBarItem setImage:[UIImage imageNamed:normalString]];

controller;

});
