Can we change the app icon (icon which you see on the home screen) on the fly or based on the setting.
Usually this icon is pre set before publishing the app on app store. As user installs the app it comes on the home screen.
We can change the icon later any point?
I don't think the app icon can be changed on the fly. The configuration for the icon is static and part of the build settings.
No. Jailbreaking your phone seems to be the only option. Also, this has been asked many times before:

On my react-native app I implemented dark mode, but this only is managed locally on my app using redux. On my iOS Splashscreen I implemented dark mode too.
The problem is, when I switch to dark mode locally(redux), the design on my app changes, everything is ok, but not the Splashscreen. I realized that only when I change the Appearance settings (Settings -> Developer -> Dark Appearance) to dark Mode, Splashscreen mode changes too.
I know that I can base it on user preferences to change to dark or light mode the app, but I need to control this locally and the dark mode apply on my app and Splashscreen also. Is this possible?
So, I guess, I need to change somehow the "Dark Appearance" programmatically. How can I get this?
You can try using react-native-appearance-control. Combine this with the Appearance API in react-native, and you can implement a dark mode toggle that the user can interact with.

How to get rid of this default white launch screen in ios? I have deployed my app in App store , this screen is still showing in live version . I want to start my app with my custom splash screen.
How to solve this? anybody can help please.
Thank you in advance.
In iOS content displayed on Splash screen is loaded from LaunchScreen.xib file.
To view this file:
Open your project in xcode.
On the left menu, expand your project node and then expand your project framework node.
There you will find LaunchScreen.xib file, open that.
Once you open it, you will find configuration settings on right bar where you set the attributes of the content to be displayed, but before that make sure that you have placed your necessary image files on image assets, in order to be accessible from the configurations settings.
You can use react-native-splash-screen in order to hide the default splash screen configured in ios/YourAppName/Base.lproj/LaunchScreen.xib.
This default splash screen will still be seen very briefly so you can get rid of the text in it and change the colour if needed (in your favorite IDE) to have a nice transition to the next screen (your custom react-native splash screen).
About a week ago xcode showed me some error and when I clicked to solve the problem, xcode added this picture:
My questions are: What is it good for? Why do I need it?
Thank you.
Yes you must include one.
From Apple's Interface Guidelines
To enhance the user’s experience at app launch, you must provide at least one launch image. A launch image looks very similar to the first screen your app displays. iOS displays this image instantly when the user starts your app and until the app is fully ready to use. As soon as your app is ready for use, your app displays its first screen, replacing the launch placeholder image.
Without this default image (or a LaunchScreen storyboard), your app would not take all the available screen space on iPhones with 4" displays (iPhone 5, 5s, SE). This is the default image that those iPhones would use.
Of course you can (should!) change it with the one you designed.
Runtime, leading to the top and bottom of applications were empty out a lot , because the application is based on a 320x480 size to run.
Small problem here, I'm building an app for ios, and I've added and icon to my project 57x57, and 114x114, but when I run my app on the device, icon is very dim, when original is very bright. How can I fix it? Does it matter if I build my app in debug mode or release?
iOS adds a gloss/shine effect to your app icon that can sometimes reduce the saturation of your image. Add the UIPrerenderedIcon flag to your info.plist file as described here to disable this.
EDITED to add iOS5 details
On iOS 5 there is a new key for specifying icons: CFBundleIcons is the raw name and it displays as 'Icon files (iOS5)' in the plist editor. To turn off the icon shine effect on iOS 5 devices you need to set the UIPrerenderedIcon flag on the Primary Icon as shown below.
To cover all cases (iOS3 - iOS5) you need to specify UIPrerenderedIcon in both places.
This is probably due to physical differences between your desktop monitor and iOS screen. Only thing you can do is redesign the icon and check the colors on an iOS device.
Check the brightness setting of your device's display. Perhaps it's not "up" as much as you think.
Or, you can disable the "shine" effect that iOS applies to your icon by adding the "Icon already includes gloss effects" boolean to your Info.plist file. That might help.
I want my app to have:
Menubar extra icon (by the clock)
App Menubar ("File, Edit, View, Etc")
I do not want my app to have:
Dock Icon
Is this possible? I am deploying for 10.6 and 10.7 via the Mac App Store if that matters.
Setting LSUIElement in the info.plist file removes the dock icon, but it also removes the menubar.
NSApplication's setActivationPolicy might be what you are after.
[NSApp setActivationPolicy:NSApplicationActivationPolicyAccessory];
Please note the discussion:
Currently, NSApplicationActivationPolicyNone and
NSApplicationActivationPolicyAccessory may be changed to
NSApplicationActivationPolicyRegular, but other modifications are not
supported.Needs links to running application
As per NSApplicationActivationPolicyAccessory's documentation you may need to programmatically ensure that the menu bar appears.
You could create two "separate" applications. One that has a dock icon and menu items,the other one has just the icon by the clock.
When you click on the icon by the clock it launches the dock application. When you close the dock application the 'background' application stays running.
If that model will work for you then that's the way to go. But I would weigh that effort against what File-Edit-View will do for you.
