Images not all showing up on simulator but shows in storyboard

问题

I am pretty new to iOS development and I was poking around in storyboard in Xcode 4.5.2. I started a new tab bar project (5 tabs) and then dropped in some images (UIImageViews objects) to them, everything looked good and the build came out fine on the simulator but not all the images are showing up. The same image would be showing on the Firstviewcontroller but it won't show on another viewcontroller. And I can't seem to add new image objects into the firstone (meaning i can place it in the storyboard but new ones won't show up on the simulator), It almost seems to be showing cached screens. For example, I just randomly place images all over a viewcontroller and then shifted them around and ran the simulator again but the positions do not match.

Does anyone have any information or experience with this on Storyboard?

Thanks in advance. Ray

In my case when I have created new project in Xcode 6 I can not show the images in the Simulator and as well as in device. I have imported all the images in the image assets making a folder within that.Now I have imported all the images, all are working fine now. All images are now showing now.

Follow these steps:

STEP 3:

and then Import images which you need. Reference Link: StackOverflow link

I had a similar issue. But later found out that this was because I had put the images in a real folder in the app directory. So there was my project's folder, which contained another folder named 'Assets' which contained the images. This was solved when I moved my images out of the folder and put them in the project's root folder.

In my case the picture was a JPG and not a PNG. Replacing image in xcasset for the same image converted to PNG was the trick.

Restarting simulator fixed my problem. I think it was a cache problem.

NOTE: I'm using iOS 10 with xcode 8

I encountered this problem after I refactored storyboard. The possible solution: - Go to Storyboard and select the image you don't see in the simulator. - Go to the Attributes inspector and re-select the image again.

After Storyboard refactor, sometimes Xcode assigns Unknown image to the UIImageView.

Reselecting the image solved the problem.

@PressRay, I have been toying around with things and have some suggestions. I have moved this to an answer, because they would have put us in chat if we kept going. But hopefully this will do it. First off, I think you should make your tab bar from interface builder, perhaps you have input some code incorrectly. You can either start one from the first screen of create a new project, or you can drag one in from the library. But it is a Tab Bar controller. Then for each of your five views, you can place a view controller on the screen for it. Then you can drag from your tab bar controller to each of the five new view controllers and select relationship tab bar controller. This will set up each vc for you.

Next I would suggest you turn off auto layout to get a feel for story boards first before you jump into auto layout and constraints. That is why I think your png's are not showing up. The two lines look like they are too close together because of some contraint moving them. To do this select the view controller, make sure it is just the view controller and then in the right hand view, go to the file inspector, it looks like a page icon. Under Interface Builder Document should be a check box for Use Autolayout. Click this so there is no check mark. Now you will be using struts and spring on each vc that you turn this off. So go ahead and turn it off on all of them.

Next you have some png files to put in. Drag your image views to wherever you want them in any of your vc's. Then hook up the png files by selecting the image view and then once again on the right hand view select the attributes inspector and under the drop down menu of Image find the png that you want. Then you can move the image views anywhere in the vc that you want. I think this will solve your problem. Let me know what happens or if you have any questions.

For xcode beta (swift 4) converted the jpg to a png file, and created a folder called images.xcassets, added the png file to the folder. It worked going to try adding the jpeg to the folder and see if the image shows up. I just tried the jpeg and its not showing up. So my conclusion is to use png files and create a folder to hold the png files. Add the folder right after the Main.storyboard. Hope this helps.
