问题 Can I change the background color of a specific UITabBarItem in a UITabBar ? I know how to change all the background of the selected background, using: [[UITabBar appearance] setBarTintColor:[UIColor redColor]]; [[UITabBar appearance] setTintColor:[UIColor blueColor]]; [[UITabBar appearance] setSelectedImageTintColor:[UIColor yellowColor]]; But can it be done for only one item without subclassing? Thanks 回答1: You can add a subview to the parent tabBar, and set a background color on the

What size should TabBar images be?

由 六月ゝ 毕业季﹏ 提交于 2019-11-27 06:15:23
I have icons for a tabBar of size 100. I checked at Apple's Human Interface Guidelines and it says the image size should be 30x30 / 60x60 . But as the height of tab bar controller is 50, I kept the size of the image at 50x50 . Now, when I run the project, I see the ugly design below: Any idea what size images I should use so that the design will be perfect? Note: I am not writing text also (e.g. Home, Search, etc). The text of the tab button is there in the image itself. 30x30 is points, which means 30px @1x, 60px @2x, not somewhere in-between. Also, it's not a great idea to embed the title of

Moving UITabBarItem Image down?

Normally on each tab of a UITabBar you have a small image and a title naming the tab. The image is positioned/centred towards the top of the tab to accommodate the title underneath. My question is: if you want to have a tabBar with just an image and no title is there a way to move the image down so it centers better within the tab? I am using (see below) currently: [tabBarItem setFinishedSelectedImage:tabSelected withFinishedUnselectedImage:tabUnselected]; but would prefer to use to larger image with no title, at the moment if I make the image bigger than about 70pixels@2x it starts edging off

I've been trying to find the solution to this for the last week, and I have had no luck after trying every possible solution I could find or think of. Every solution I found and have attempted has either not worked, or been outdated. I have 5 UITabBarItem 's in a UITabBar placed within UITabBarController . I want to change the background color of the UITabBarItem when it is selected, and of course have it change back when the selected item changes. I am using Swift, and iOS SDK 8.3 in Xcode 6.3.1. If you can only answer in Objective-C that is fine too, any answer will help! Thank you all in

由 孤人 提交于 2019-11-27 02:50:32
Here is my tab bar: The following image shows the program being run and the "NEWS" item selected: It is clear the bar tint color is working fine as I want !

I want it to stay white. Why is the text changing to a white color when selected but not when it is unselected? I basically want the item color and text color to be white all the time. How do I achieve this? Thanks for any help. Does it require swift code for
