So originally I made some custom tab bar icons that looked pretty neat, and I put them in my project. I recently just realized they look disgusting. So, I got some free tab bar icons and replaced the old ones. When the app loads, I at first see the old icons, then when the app is fully loaded I see my new icons. Now I don't want any user to see this. I then took action by permanently deleting the pictures not only from Xcode, but from my hard drive, which still did not fix the problem. I went to my DerivedData folder and emptied all my cache files. No success. This is a giant project and I don't want to have to make a new app, copy paste, make all the connections, and get all the frameworks again.
You said "when the app loads" you see the old icons. By any chance are you seeing this during load of the app, before it's actually usable, and as soon as the app becomes usable it's showing the new icons? I bet your default.png shows the old icons and you never updated it.

Why Changing launchImage so troublesome?
My app used a .storyboard for a Launch Screen.Now, I need to replace a new picture for the launchScreen. First of all, I put the picture into 'Image.xcassets', the launchScreen is white.
Then I search some ways to solve it .
Delete the app and restart. This can change the launchImage, but this method is not good for the users.
Put the picture in the root directory. In a few days the launchScreen does load the new image. but maybe 2 or more days later, launchScreen become white or black.
Has anyone ever experienced this, what advice? thanks for any help.
These caches are used by Springboard to make app switching fast. This isn't a problem that will affect your production users and should in theory go away the next time Springboard decides to snapshot your app.
That being said, this isn't a problem you can fix. This is a bug in Apple's code not yours.
I've been literally trying for two weeks to get an icon for an action extension to appear, but absolutely nothing works.
I've seen past questions such as this iOS 8 Action Extension icon sizes and this Why isn't my iOS8 Application Action Extension App Icon showing up? but they are of no use.
I've created an Xcode template project purely to try every combination of things mentioned in the other questions, still without avail.
1) The first thing that's mentioned is that the action extension should have its own asset catalog, ok here it is:
2) Secondly that it should contain an app icon image set, here that is:
3) Thirdly people say they had to add its target membership to the extension and to the app. Here that is too (in all of these things, I've tried variations such the membership being just the extension, just the app, both)
4) Fourthly, people mention they had to add it to the compile sources, here that is, as well as it being copied in the bundle resources:
5) Some say it also needs to be copied in the container app's bundle, here that is, and for good measure its been added as a compile resource of that too:
6) One person says it was necessary to add the container apps assets to the extension bundle, I can't see how that would work as the icons in the container app are colored and not matching the requirements of the extension icons, but what the hell, might as well try everything right, and while we're at it lets add assets everywhere:
7) The asset icon itself is important, colored icons are not displayed, but I tried it anyway. A simple black and white image is described as the white parts appearing as grey but I've tried that anyway. Trying unsupported icons was just desperation and experimentation, of course I'm actually using an icon with a transparent background. When posted here it appears on this webpage as all white of course, but the non-black parts are actually fully transparent and have an alpha of 0:
But despite trying many combinations of all the various steps above, this is what it looks like on the device:
This is using iOS 10.n, latest 10.7 (it hasn't worked with any beta) and Xcode 8.6. If I download an app from the app store that uses action extensions then their icons are appearing, so there's no issue with the 10 beta. The issue is either something building the app with Xcode beta, or some step I've missed out - if that is the case, then what?
Finally found out the solution - in order to get it to work its additionally necessary to set the Asset Catalog compiler options of Build Settings section of the extension to specify the name of the app icon set within the asset catalog:
How to set an action icon really is the most appallingly badly documented aspect of iOS, totally shockingly awful.
This is a newbie question. But I would like to change my old UI (pngs) on my current project to some new updated ones that are of similar size. Is there anyway to drag and drop the UI directly without affecting the actions so the buttons still work the same on the app. Or do you have to recode everything when you change UI? I'm not really sure the steps I need to do, but I have all the new UI ready to go. Can anybody guide me through these steps?
Another question is, I have a video editor and want to test out a video player in the simulator at run time, but right now I can see my music or video files because I don't have any in the simulator. How do I import these files into a project to test it out (on the computer), I know the camera roll on a phone would work.
If anybody can give me some guidance, I would greatly appreciate it. I know these are newbie questions.
Thanks,
If the new images are the same size of the old images, just rename the new images exactly like the old images and then overwrite the old images at the project's path.
And for the video files, drag the video files directly to the iOS simulator. The video will open in the Safari, click the share button in the tab bar of the safari and hit "Save Video".
I'm using Trigger.IO's toolkit to add the launch images. After doing so, the app fails to remove them from view after initially starting up the app. After hitting home and then going back to the app, the launch image disappears after launch.
The app isn't actually freezing after launch but just keeping the launch image at the forefront. I used a partially transparent image initially, and it appeared just to have a high z-index. I could use the app, but the launch image remained on screen over the top of everything.
As of platform version v1.4.20 you can control the launchimage visibility (http://docs.trigger.io/en/v1.4/release-notes.html#v1-4-20).
We've seen some instances of very early usage of the Forge APIs causing the launchimage not to show. In most cases, leaving the launchimage to hide itself manually is fine; if you're having problems or want more control over the launchimage, you can use forge.launchimage.hide.
Very odd, the problem seems to have dissipated even though I have not attempted to address it directly considering it was merely a config file change.
I'll report back if the problem surfaces again, but all is well currently!
Try add to use this code line
[window setRootViewController:mainController];
For full help, we need a some your codes
Thanks for the time to look. I have a weird problem. my Launch image (AKA Splash screen) seems to automatically be tied to my App icon. so I cant change one with out changing the other. In other words, when I add a new app icon, it changes the launch image to match.
I am guessing this has something to do with the .plist file, but I cant figure out where to fix it.
Thanks for the time!
You can specify them differant in plist file. See here
ALSO
Check Apple's link for default name of different files. You just need to rename with default name and add the image files in your project.
