I've been searching for hours now about my first task in my job. Today, I'm familiarising myself in using Macbook. It is really hard for me to adapt to changes, because I'm a Windows user. I used to be a freelance C# programmer.
Anyway, what I've learned in the first hour is the Storyboard. How to add a segue, for example, clicking a button from View1 and then the View2 will show. However, the program returns an error, I think I need to have a code first.
But let's go to the question: (How to make a splash screen with just a label not with an image)... I need to have a 1st screen which has a hello world label, and then after 2 seconds, the 2nd screen will show.
What I have done so far:
learned Story board.
checked the "Is initial view controller" of my first screen.
For the Splash Screen in iOS Application You don't need to do code. You just need to following dimension Splash image and add it to asset.catalog.
iPhone 4 & 4s size:
Default.png (320px X 480px)
Default#2x.png (640px X 960px)
iPhone 5 & 5s size:
Default-568h.png (320px X 568px)
Default-568h#2x.png (640px X 1136px)
iPhone 6
Default-667h#2x.png (750px X 1334px)
iPhone 6 Plush
Default-736h#3x.png (1242px X 2208px)
This All iPhone Application splash screen size and its name conversation. now you can set Splash with two way:
Fist:
when you tap the right small arrow near of launchImage (->) you can see the following window:
Currently there is empty because from right side there is no any target selected so if your deployment target is 6.0 you need to set check mark like following screenshot so you can see the all image need box :
See when you add wrong dimension image in catalog you can get warning at top right corner and when you tap on this warning you can get actually dimension. see the following screenshot for:
So from the warning log you can know which dimension image need for which splash screen.
Other way
No need to use Asses Catalog and no need to use LaunchScreen.xib you can still use old way:
In plist you need to add following data:
Add one row by tap (+) its called UILaunchImages
and you need to fill this row like following
that's it no need to do any thing hope that answer helps to other as well.
When you create a new project it automatically create LaunchScreen.xib
1.) Now from Toolbar window select UILabel drag it to launchScreen.
2.)
Go to Your Project(Right click) -> New File - >iOS -> User Interface -> View(Give any name to it).
This will create nib file with label(as your project name)
Now Open the Right Inspector of Xcode and check the Use as Launch Screen that's it ur work done.
Below i have attached screenshot which may help you
Go to Launch Screen.xib(this is the splash screen which gets called automatically by xcode after an app is launched) --> clear everything u see inside the xib except the xib itself--> drag and drop a label in any position, write a text.

Running my App in the iPhone X Simulator (GM Seed) I am noticing two strange effects:
the App does not use the full screen space (top and bottom area is black)
a strange white bar beneath the title bar
Does anybody know what is happening here and how to resolve this? I can't find any new settings in Interface Builder.
When using launch images (instead of the much easier Launch screen file), you need to provide the properly sized launch image for each device size you wish to support. Once you add the additional launch image, your app should take advantage of the new screen size.
The new iPhone X requires a launch image sized at 1125px × 2436px which is a 3x image for 375pt × 812pt.
Of course if you switch over to using a Launch screen file instead of individual launch images, your app will automatically adapt to all device sizes without any additional work.
I have figured out this issues in iPhone X. Launch image size (1125*2436px)
Please flow this below steps.
1.i)Choose your project name in Xcode.
ii)Select your project target
iii)Then select Launch images source
You can get Migrate popup
i) Choose Assets
ii)Select Migrate
After that select your Assets.xcassets in your project
Then select Launch image in assets
i)Then select attribute inspector
finally check your Launch image source. you can see set Launch image.
iPhone X needs different launch image sized 1125px x 2436px (375pt x 812pt #3x).
Check human interface guidelines for more details.
I have figured out how to fix (though I still don't understand why this happened only on iPhone X) LaunchScreen storyboard on iPhone X with seeing black top&bottom bars.
I have LaunchScreen storyboard with one UIImageView.
UIImageView's top&bottom has to be pinned to SuperView's top&bottom. NOT to SafeArea.
I fixed it by simply inserting some random text in the Lanch Screen File textfield. I dont even have a Launch Screen File... XCode is so buggy.
update
Although this fixes it in simulator (still very weird and unexpected) when uploading a binary to iTunes Connect it will fail due to not finding a LanchScreen file of name "random-name"
Just ran into this while trying to update an app I hadn't worked on in a while.
On Xcode 9.4, I was able to fix this by doing the following:
Add a launch screen by going to File -> New -> File... -> Launch Screen
Make sure the newly added launch screen storyboard is selected as the launch screen file under project settings.
If you already have a 1125px × 2436px launch image but the app is still not using the full screen check to make sure that your image is PNG.
if you removed LaunchScreen.storyboard; Choose your project, select your project target, General -> App Icons and Launch Images -> Launch Screen File: Select here Main.storyboard instead of LaunchScreen.storyboard
Just had this problem... When I selected the project & the correct target I had a blank for the 'launch screen file' under the app icons and launch screen images tab. I set it to the default LaunchScreen and the resizing issue I faced was taken care of.
You may check in project target launch screen file is not set to empty if it is empty it may cause problem.
Yes me too face that top spacing issue in iOS 15,
iOS 15 needs some new size of the Launch images
So you please check your all the launch screen images
Check your Attribute inspector is portrait for Launchscreen

I have a stupid question:
Why when I debug an app for iPhone in an iPad the simulation start in a iPhone 4 screen and not in other types of screen?
If I understand you correct, please use this button to choose which one you want to use in simulator :
when you click you should able to see some list like this :
If you're not able to see other iOS version you can add them in Xcode/Preferences/Downloads section :
please let me not if you're not asking this.
To set the App to work on a different size screen you must add that screen size to the LaunchImage asset.
1) Create an splash screen launch image for the size of the iPad you want to use.
2) Import it into your project
3) Open images.xcassets in the Project Navigator
4) Select LaunchImage
5) Drag and drop the splash screen launch image to the correct iPad asset
It is very frustrating and seems strange, but the Launch Image size tells the App what dimension it can run on. Setting image sizes in your screen or using auto layout won't work unless that Launch Image size has a splash screen
We have an iPod app built with base SDK as 5.1.
App has a tabBarController with three tabs and each tab has a UIViewController to load a different view.
The app works fine for iOS 6.1 and iOS 7 (3.5 inch display) simulator and device but when we run the app on
iOS 7 (4 inch display simulator) or device we are getting black bars at the top and bottom of the view screen in all three tabs.
If anyone can suggest reason for this or some feasible solution to this problem, it would be really helpful for us.
Thanks
First thing is that you must add the required default image for 4 inch screen display. Check Properly in you project have image with name Default-568h#2x.png (640 × 1136 pixels)
This Default-568h#2x.png is Necessary for Support app in 4 inch Screen display
Ones you add this image in to you working Project, Remove old Build from device or Simulatore, clear Project and re build and check Hope you issue will solve.
Edit:-
After fix the black Bar issue you can check the device like my answer Give here check this:-
Detect device type
you have two choice if you can't use AutoLayout
First
Create two xib with same class one for 3.5 inch screen and one for 4 inch screen set using macro with checking which screen appear.
Second
Set Self.view frame using macro with checking which screen appear.
There are also other methods you can use for set self.view frame as using window frame or UIScreen
My problem was I accidentally deleted the value found here:
I added back LaunchScreen, and made sure there was a LaunchScreen.xib. Maybe it will help some others.
Ive had the same problem - black bars at the top and bottom. It was simply solved by setting the drop down in "App Icons and Launch Images" to Main_iPhone:
App Icons and Launch Images Screen Shot
I was facing same problem . I just added launch image and it worked for me.
XCode->Click on Project File -> Select Target-> App Icons and Launch Images -> Add launch image source
This worked!
Pay attention to Step#5 and Step#6 below:
1.In xcode, Click on the Project file in Project Navigator
2.Click General tab
3.Type "Main_iPhone" in the Launch Screen File field
4.Save
5.Remove the app from device or simulator
6.Then in Xcode go to Product Menu and then select Clean
7.Build again
I've come accros a problem with iOS 8 on the iPhone6 and simulator, when you have a UITableViewController with visible separators there seems to be some render problem. Now I could post some code but really if you make just a simple UITableViewController you would have the same problem, just look at eBay and Kijiji they all have this issue.
Normally you wouldn't see this small difference if it only happened once in a blue moon but if you scroll none stop you will see it flash. (less on Ebay since their separators are too close to white but Kijiji is pretty apparent)
Sorry I wanted to post a screenshot but sadly I don't yet have the reputation to do so therefore you will have to try it out yourself's.
Any help would be appreciated
Thanks
The reason why the separators flash is because the app is not designed for the larger displays, and the phone is upscaling the app to fill the larger screen. Since the separator height becomes fractional, the separator line crosses pixel boundaries and becomes antialiased, making it appear wider, lighter, and/or darker than normal.
The answer is to (wait for the developer to) update the app to support the native resolutions of the iPhone 6 and 6 Plus.
You can enable native resolution in your own app by adding launch images or a launch screen file.
Launch images
iPhone 6 requires a portrait launch image of 750x1334.
iPhone 6 Plus requires both portrait (1242 x 2208) and landscape (2208 x 1242) launch images, since it can launch apps in landscape as well as portrait.
Launch screen file (iOS 8)
You can add a launch screen storyboard or nib through Xcode.
In Xcode 6, open the File menu and choose New > File... > iOS > User Interface > Launch Screen.
In the General tab for your project's settings, look for the App Icons and Launch Images section. Set the Launch Screen File to the name of the file you created. This will set the UILaunchStoryboardName key in your Info plist.
Add Renders with edge antialiasing in your plist file, fixed the problem for me.
Remove the Clips Subviews on my custom cell did fix the issue for me.
