text on iPad looks blurry - objective-c

i have created the iPhone app
on iPhone it works perfectly but when i run it on my ipad and move it to 2x
text in my apps display blurry
is there any solution where on my retina ipad text also looks smooth as on iPhone

I had the same issue few month ago, it is because your application is only for iPhone. Please do not worry about this issue because this problem will only on iPad (non-Retina). and for iPad with Retina I will work fine. You will see the smooth font on retina (iPad). and If you want the same on iPad (non-retina) then go for a universal app. I solve this using universal app.

Why app is showing black space in iPad React Native

I have designed a app in react native and it is working fine for IOS and android mobiles. but when I run it on the iPad it is showing app in the centre and black space of 2 inches in the border. App is showing too small all space covered by black. Can anybody tell me why it is happening?
We can change it in Xcode from build setting targeted set to 1,2 and it will resolve.
You have to change the Targeted device family. Select the project, then info-->Deployment--->Targeted device family to iPhone only and you have to do the same thing in targets. After that your app will be only for iPhone.

xcode not recognizing screen size height 677

I have an app I am updating because of the Launch Screen requirement instead of launch images.
In so doing I came up with many many warnings that "views without any layout constrainsts may clip their content or overlap other views". When I went in and tried to address the problem no matter what I did the warnings multiplied. So I am attempting to rewrite my code to get the screen size and place and size my objects for each phone. The problem is that Xcode apparently does not recognize iPhone 6 screen size on the actual device. In the simulator iPhone 8 is recognized but I don't have an actual iPhone 8 to try out. I would assume it is the same size as the iPhone 6. I have looked on line and I saw this was a problem and possible fixes were to "make sure iPhone 6 launch images were available", but since launch images are no longer that isn't a solution. I also tried
if([UIScreen mainScreen].fixedCoordinateSpace.bounds.size.height == 667.0){
also but that didn't help either.
I can't believe Apple doesn't want to have developers not get the screen size for iPhone 6.
Is there a work around or new way to get screen size for iPhone 6?
Does this problem happen on iPhone 7 and 8 and iPhone 6,7,8 +?
I just saw that I have to include specific sized launch images with my launch screen with specific names. Is this true? How do I do this? Is there a GOOD tutorial?
I am at my wits end and need a solution.
I found a place where I created and installed images for all iphone and ipad portrait sizes and put them in Launchimage in my image asset folder. my app only runs in portrait so I didn't think I needed to make landscape images. Anyway, even with all the correct size images, iphone 6 4.7" and 5.5" it still launches seeing the iphone 6 as a 5. In fact now it launches with a blank screen no launch images showing up at all.
So I added the landscape views and had forgotten an iphone portrait view. Now in the simulator iphone 8 and 8+ are recognized as the correct device by height but the launch image still isn't loading for iphone 8 and 8+ as well as ipad 7gen, air3gen, and pro 9.7. Only loads images for iphone11, 11pro, 11promax and ipad pro11 and 12.9.
On the actual iphone 6 the launch images isn't loaded and it still is recognized as an iphone 5. This has to be a Mess up by Apple.
Suggestions?
Thanks

Xcode 6 ViewController content is smaller than the simulator screen

i'm developing app for both IOS7 & IOS8, and using storyBoard with size classes enabled.
app works fine in all simulators from iPhone 4s IOS7 to iPhone 6+
but the viewController is smaller than the screen in iPhone 5 with iOS7
app supports different orientations, i tried and canceled orientations but didn't work. i rested the simulator content, didn't work. I tried to change the initial view controller, didn't work. I cleaned the project, didn't work
To run your application in fullscreen in iPhone5 you must provide Launch Image for iPhone5 with resolution 640x1136.
If you are not including Launch Image of the size iPhone5 require then app will run in the centre of the screen, showing black area at top and bottom.
You can also refer here for more information.
Make sure there is a Default-568#2x.png in the supporting files

iPhone and iPad image size

I tried to develop universal app, and I displayed image with size 768*1024 on iPhone 4 and I displayed the same size on iPad screen and I get good resolution for both is this normal? the same image I can use in iPhone and iPad or this happened only on simulator? whats the best size for iPhone 4 and iPad?
I appreciate any help.
Thanks.
In the iOS Human Interface Guidelines image sizes are dealt with. The launch images cover the whole screen and thus give the best resolution for the devices.
