I'm trying to customize the logo on the signIn page using the following:
AWSMobileClient.sharedInstance()
.showSignIn(navigationController: self.navigationController!,
signInUIOptions: SignInUIOptions(
canCancel: false,
logoImage: UIImage(named: "MyCustomLogo"),
backgroundColor: UIColor.black)) { (result,
err) in
//handle results and errors
}
However, the default logo still appears but the background does turn black. I have MyCustomLogo in the project but it just does not take. I'm fairly new to Apple development so I'm sure I'm missing something simple or maybe I'm not. I just need help please :)
I am able to add a custom logo to my Amplify Drop-In UI using the iOS SDK. You have to be sure to add your logo assets in the Assets.xcassets folder for your project to know where to look and override. Also, I presume you named your logo MyCustomLogo as you show in your code block above. You don't need to specify .png.

I use privacy-screen plugin to hide content when app is in the background, but it shows just gray background. I need to set splashScreen instead. Any suggestions?
I tried splashScreen plugin, but it is not working for me.
I don't know if it's the best way but I think that using Capacitor appStateChange from #capacitor/app (documentation) you could show and hide a screen with your logo when app is in background or foreground.
import { App } from '#capacitor/app';
App.addListener('appStateChange', ({ isActive }) => {
console.log('App state changed. Is active?', isActive);
if(!isActive) showLogoScreen();
else hideLogoScreen();
});
I hope it helps :)
For iOS, I did it simply in native code: just find the "applicationWillResignActive" method in AppDelegate and insert a view on top of the window.
For Android, sadly I couldn't find a better solution. The "gray background" you described is likely the implementation of Hide screen in 'Recent Apps List', but allow screenshots
I am trying to use iOS image picker plugin in my Flutter using MethodChannel.
But I found that if I open and close the image picker(My Image Picker button), ImageCache is reset to zero.
So NetworkImage gets loading again like it has never been downloaded before.
On the other hand, Flutter's image picker(Flutter Image Picker button) doesn't reset ImageCache to zero so it is fine.
Why is this happening? Did I miss something?
I have tried overriding ImageCache size like below but the problem is not solved:
overriding image cache in Flutter
Please help me...
my app home tab
my app image tab
flutter image picker
I recommend to use flutter package to make developer easier to code and even the package also use MethodChannel, inside code is also coded pretty well such as error handler etc. It is also works for IOS and Android, which is this is the function of Flutter that make developer easier to deploy IOS and Android apps.

How to load icon based on the json response
This is not supported by Font Awesome Flutter.
There is another package to help you with that: Icons Helper
However, if you try right now, you will see that Icons Helper refers to an adobe icon that does not exist anymore. It has been removed from the package in the master on Git but not yet on PubDev.
You could also just integrate icons_helper.dart in your project and maintain the map you need in your app.
I am working on a MacOS application where the app should show the application icons. For some app it works, for some apps it don't.
One the app for which I do not get the application icon image is the Notes.app.
let icon = NSWorkspace.shared.icon(forFile: "/Applications/Notes.app")
For Numbers.app, for example, it is loading the app icon as expected.
What is the reason behind?
I have figured out that icons are only appearing for those applications where the application has an associated filetype. Applications which do not have associations does not return the icon.
There must be a was to open an .icns file. The path to it is clearly accessible and the content of the icon file should be too.
Ok. I have figured out that some Applications are located under /System/Applications, but appears under /Applications too. This is causing the problem above.
I will like to know how to take a screenshot of the iOS host app with the use of a share/action extension.
My use case is as follows:
use the Safari browser to access a webpage (https such as gmail)
tap on the Share button and select the extension
the extension will take a screenshot of the current webpage
An working example for this use case is the Awesome Screenshot iOS app.
I had tried the following methods
reload the baseURI (loadRequest) on a UIWebView/WKWebkit (would not be able to access https contents such as Gmail). So not doing any reload (Awesome Screenshot is not doing a reload btw)
Used the ExtensionPreprocessingJS to obtain the DOM contents through the arguments.completionFunction function. I could not extract the document.body here although i could get the source etc. loadHTMLString with the baseURI will mess up the presentation layer.
Used html2canvas in the ExtensionPreprocessingJS to obtain an image and appended it to the host app's webpage as a child but do not know how to extract it. Also, the image got lost for some webpages such as Gmail.
Mobile Safari does not have the visibleContentsAsDataURL method.
I think a viable approach will be to use the html2canvas in the ExtensionPreprocessingJS but how do I save this image somehow?
Edit: So the below works in the Simulator but does not work on the device. I'm presently looking for a solution as well.
Here's a solution that I think the Awesome Screenshot app uses:
func captureScreen() -> UIImage
{
// Get the "screenshot" view.
let view = UIScreen.mainScreen().snapshotViewAfterScreenUpdates(false)
// Add the screenshot view as a subview of the ShareViewController's view.
self.view.addSubview(view);
// Now screenshot *this* view.
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, false, 0);
self.view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
let image: UIImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
// Finally, remove the subview.
view.removeFromSuperview()
return image
}
