iPhone (iOS 7) App Icon Strange Behaviour - ios

I am facing the problem with the App Icon on the iOS 7 Device, the Problem is : I am getting a black border on the top corner of the icon. The Icon size & Name i used is:
Size : 120 X 120 pixels
Name : Icon-60#2x.png
(Sorry, I can't post the screen shot/Image here as i need 10 reputation points to post an image. Hope you guys understands)
Please help me.
Thanks in Advance !
EDIT:

iOS HIG guidelines suggest,
Avoid transparency. An app icon should be opaque. If the icon’s boundaries are smaller than the recommended sizes—or you use transparency to create “see-through” areas—the resulting icon can appear to float on a black background, which tends to look especially unattractive on the beautiful wallpapers that users choose.
Check if there is any transparency present in the icon, if yes, please remove it.
You should avoid rounded corner icon, because Apple applies masks to your icon image for this. Provide a sqaure-ish icon of dimensions 120x120 pixels.
Hope that helps!

For iPhone and iPod touch, both of these sizes are required:
120 x 120 pixels
60 x 60 pixels (standard resolution)
Reference by apple doc

I've faced same issue like this. I'd provided image with rounded corner. When I provide flat image with this size, I'll see correct icon. Seems to be silly. But It has work.

Please try these steps
STEP 1:Remove the transparency of app icon.
STEP 2:Add square images. Images with rounded corners also make this issue

Why huge icon 512 x 512 still rendering as pixelate on iPhone?

I'm on Swift 4.2 - I have an icon 512 x 512 with resolution 300 ppi.
I imported into my asset folder, moved it to the 2x section, and select preserve vector data
In the phone, I notice it rendering as wrinkle/pixelate in a very weird way.
When I zoom I see this 👇🏼
Am I do anything wrong? Please advise.
Are you sure it is pixelated? Maybe I don't have eagle eyes but I feel right when seeing the icon on the iPhone. If you take simulator screenshot then zoom out, eventually all icons will look pixelated like that. It's worth to mention that Preserve vector data should go with a PDF and Single Scale, otherwise it doesn't do anything. If this is PNG, then you should have #1x, #2x and #3x image.
Please make sure about below points.
1) Add a PDF image to the asset catalog and be sure to tick Preserve Vector Data as before:
2) When adding the image view or button to the Storyboard make sure to tick Adjusts Image Size:
3) If adding the image view in code:
imageView.adjustsImageSizeForAccessibilityContentSizeCategory = true

What is appropriate size of icon for 3D Touch shortcut item on home screen?

I couldn't find it on Icon and Image Sizes.
But I mean, what is the size of following icons?
Below mentioned article, there is a note:
Once you download this, you will see that there is a recommended size:
104x104 for 3x
70x70 for 2x
Since Apple will automatically size and re-colour the icons, it's better to use a PDF, which has the added benefit of looking sharper and a reduced risk of causing clipped edges if margins aren't used.
Here's a comparison of PDF vs PNG (exact same icon, originally and SVG exported from Sketch):
The size is also the same.

iOS: How to set the proper image scale for a bar button item

I'm trying to add my own image as a bar button item, but I don't know how to get the image to scale properly. Apple's Human Interface guidelines recommends that my image be 44x44 px, but when I use a 44x44 px image, it is too large for the toolbar, as you can see:
When I use a smaller version of the image, it looks pixellated on the Retina display. What am I supposed to do here?
In images.xcassets, you can add the images as 1x, 2x and 3x. Xcode will use the appropriate image size depending on the device.
You need to follow apple guidelines for designing you can find it from this link https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/LayoutandAppearance.html#//apple_ref/doc/uid/TP40006556-CH54-SW1
You can find the attached screenshot image for correct sizing for the UIBarButtonItem image size as par the apple guidelines you have to use 44X44 for ratina (#2x) and 22X22 for normal (#1x) for UIBarButtonItem
width 22 pixels X height 22 pixels - ideal for left or right BarButtonItem.
You can resize any image to custom sizes using online tools, one such I used is

iphone ios 7 homescreen mask isn't applied correctly to my icon

My problem is that my application's icon seems to be resized to fit the rounded-corner mask applied when displayed on the home screen.
EDIT: Here's the image:
My image follows the guidelines in these locations (mainly that it is 120x120, and doesn't have pre-rounded corners):

https://developer.apple.com/library/ios/documentation/iphone/conceptual/iphoneosprogrammingguide/App-RelatedResources/App-RelatedResources.html#//apple_ref/doc/uid/TP40007072-CH6-SW4
I've tried:
1) Using an image catalog
2) Searching for the issue on this site. I looked through the first 5 paginations sorted by newest and can't find anyone who's had the issue...
3) Making sure that the image is specified in the info.plist
4) Checking the troubleshooting app icon issues on the apple developer site.
The icon always ends up drawn with the black edges.
Is there a way to programmatically make sure the mask is applied correctly?
Has someone else encountered the same issue?
It sounds like you might have the wrong DPI set in the icon PNG—if it’s something other than 72 (the screen’s nominal DPI in points), the system may be trying to scale it to match.
It looks like the DPI was correct. The problem was that there was a transparent background layer, wider than the image that Android Studio seemed to have added when it was run through that deployment process. The layer went unnoticed in preview because it doesn't highlight the transparency. Noticed it when I opened it in GIMP.
So it was a silly oversight on my part.

How big should a UIBarButtonItem image be?

I'm looking to create my own custom Sort By Date and Sort By Number buttons that I plan on placing in the navigation bar as the right button.
How big should my image be to appropriately fill the space -- the UIBarItem documentation page doesn't list anything about the size the image should be.
As of iOS 11, the Human Interface Guidelines suggest glyphs be about 25×25 points in toolbars and navigation bars, up to a maximum of about 28 points. (And the HIG should definitely be in your bookmarks if you're working on iOS apps!)
That would translate to images 25px square for older devices like iPad 2 / Mini, 50px square for most current devices like iPhone 8 or iPad, and 75px square for Retina HD devices (the iPhone 6/7/8 Plus, or iPhone X). Asset catalogs will help immensely in keeping the different asset sizes organized (and Xcode can even generate them from vector sources these days).
The Human Interface Guidelines tells you this since iOS7:
Regardless of the icon’s visual style, create a toolbar or navigation
bar icon in the following sizes:
About 44 x 44 pixels
About 22 x 22 pixels (standard resolution)
Here is a great matrix of all needed sizes for resources for all platforms
Yes, Apple suggest to use images with 22px, 44px and 66px size for UIBarButtonItems, but if you use preinstalled icons like Bookmark icon, it's sized by 25px 50px and 75px for 1x, 2x and 3x respectively.
Here are 2 icons in UIToolbar. On the right is Apple's system bookmark icon and on the left my custom icon.
Here my custom icon sized 22px-44px-66px:
And here 25px-50px-75px:
So, if you use custom and system icons in one toolbar, I would suggest to use 25px-50px-75px scaling, or your custom icons will be smaller. In fact I always use 25px-50px-75px scaling, it looks better on toolbars, as for me.
Easy: Include your images in Assets.xcassets.
How?
Clic on Assets.xcassets
Clic + icon and then click "New Image Set"
Drag and drop your image to 3x slot
Rename the image set
In the BarButton you can use this name under "Image" field
