My app icon is showing with white borders, how do I remove it?
this is happening only when I try to build the application for ios, on the android system this does not happen
I tried modifying the alpha channel but it didn't work.

It looks like your image has some white (or transparant) color on the edges. If that's the case I would open the image in a image program, zoom in, find these spots and fill them with the background color.

I use react-native-perspective-image-cropper package to crop image dynamically, and it’s work absolutely fine. But sometime when the cropping area overlay are outside of the image and I try to crop the image then it add the white background to replace the outside of the image area.
in Android it not add any white background but in IOS I face this issue.
You need to make sure that the coordinates aren't bigger than the height/width of the image. It doesn't make sense to crop outside of the image itself.
I want to use a background image for a kivy button. I have used the following builder string:
<MenuScreen>:
BoxLayout:
Button:
background_normal: './Pictures/my_background.png'
The image is displayed, however, it is much darker than expected and partially inverted. What do I have to do in order to display my original image without changes?
The resulting button
Original image
I think your problem is that the two colors in your image are grey and transparent (the white appearing areas are actually transparent in your image). In a Button, the background_normal image is multiplied by the background_color which is also a shade of grey by default. So what you end up with is the background grey showing through your transparent areas (white areas above) and your grey appearing everywhere else. So there is not much contrast. See the Button Docs for more information.
You can modify your image (using something like Gimp) to replace the transparent areas with a white color, and perhaps change the grey colors in your image with black. The distortion of the image is due to Kivy fitting your image to the button size.
Here is your image edited as I described. You should be able to click on it and download it.
Well, the title says most of it. I've tried with icon sets of 75/50/25 px and 72/48/24 px, as stated by different guides, but when I run the app in Xcode, the icons appear as (appropriately sized) blue squares. The icons are all black and white .png files, with negative images for the selected images. Any suggestions would be appreciated.
This might not fix your issue, and also may seem very obvious. But I'll put it here just in case it helps anyone.
First of all, I'm going to point out scenarios to check that can get you in this state that may or may not apply to everyone:
The asset's render type is set to Template Image
You are changing the tabBar.tintColor
If either of these are true and you are getting a solid colored square as your icon, the first thing I would check is the actual image you are using. It is probably an image/icon sitting on a white background or something like that rather than a transparent background.
If you are using a .png, .pdf, or .svg icon and want to tint the icon, you will need a transparent background. Transparency doesn't exist for .jpegs so they just won't work for tinting the icons.
This is because changing the tint will tint the whole image. If there isn't transparency, Xcode will have no idea what is icon and what is background. So a 40x40 icon just becomes a colored square.
Another benefit of using a transparent background will be now instead of having multiple images for selected/unselected states, you can just set the desired colors for .selected and .normal states and use one image.
Okay, the solution is NOT to set the image to render as image, but to use an alpha 0 background instead of a white background on the icon image.
Another tip. Don't name your image assets the same name as iOS System icons/glyphs. I had a download icon labeled download(.png). After renaming the issue disappeared. Very inconsistent behavior.
I'm working on a iOS application. My app icons has transparent background but when app installed on iPhone it shows white background.
Here is my app icon you can see the white borders:
How I can fit this icon?
You shouldn't have transparent background for app icons.
I suggest you to read the guidelines about icons. Explanation from these guidelines about transparency :
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 dark background, which tends to look especially
unattractive on the beautiful wallpapers that users choose.
Pre-rendered icons on iOS
By default, iOS will modify the icon graphic you supply to add rounded corners, a drop shadow, and a reflective shine. The graphics here shows the before (left) and after (right) effects of this transformation. Apple recommends that your icon graphic have 90-degree corners, does not apply any shine or gloss, and does not use any alpha transparency.
You cannot prevent the rounded corners or drop shadow from being applied. But you can override the reflective shine by providing a "prerendered" icon and making a change in the tiapp.xml file. You might do so to apply your own shine effects. To prevent the default shine from being applied, update the following key in the tiapp.xml to have the value true.
<prerendered-icon>true</prerendered-icon>
Please read more from appc Doc http://docs.appcelerator.com/platform/latest/#!/guide/Icons_and_Splash_Screens-section-29004897_IconsandSplashScreens-Pre-renderediconsoniOS
That is expected. You can see this Apple Documentation that explains how you should design your icon to avoid this white background

I have some colored images and same colored text on an iPhone App screen. The images show as expected, but when I use the same RGB color code on the text, it appears different on the finished app (mostly, a little darker). Why is xcode changing the color I tell it to use? How to get the text color to exactly match the color codes in the images.
Update: Here's a screenshot. I use the color picker from inside XCode, to pick the color from the image, so it shouldn't matter which color space I'm using (I'm using the same for both text and image), it still looks different.
It's very popular problem about different colors...
1) Try to use Digital color (native mac application)
2) Try to off text shadow, if you use it from your label.
3) And, all of its, is not a wright way to resolve this problem, if you want to color like on image you should correct them manually in you code or in interface builder.
