How to integrate social media for photo sharing on iOS? - iphone

I need to integrate social media for sharing a photo in my app. My app will have one UIImageView with some image and one button for sharing the image. As soon as I click on the button I should get the list of social networking apps installed on my iPhone and I should be able to share the image on selecting any one of them as shown in the figure below.

Try ShareKit (https://github.com/ShareKit)

No Camera found dialog when accessing Capacitor Camera Web Application on mobile

my goal is to access a web page, which uses the capacitor camera plugin, witha mobile device in order to take and upload photos.
I followed this tutorial on how to code a website with the camera functionality:
https://ionicframework.com/docs/angular/your-first-app
The web page is working but by accessing it with a mobile device (tried with IOS and Android) it shows this dialog:
If you click "Choose image" there will be functionality meaning it is possible to take photos or upload them.
Is there any way I can prevent the "No Camera Found" dialog or change the style of this dialog?
Thank you very much!

Register Tumblr app for iPhone app

I registered an app on the Tumblr developer website for my iPhone app. The app need to upload a photo to Tumblr with tags and caption and it's running normally. However, the photo after uploaded on Tumblr does not show my iPhone app name below the photo. It just shows the caption, tags under the photo. As Diptic (iPhone app) or Instagram, I see there is an app icon and a link to its app homepage under the uploaded photo.
I'm wondering is there anything wrong when I registered the app on Tumblr developer page or my iPhone app client missed something?
P/S: My iPhone app is using xAuth.
Thank you for reading my question. If you aren't clear anything, just let me know.
Regards,

Try to upload your app photo in 24 bit PNG format with 128x128 pixels.
You will see the app icon if you success. You can try to save this 128x128 PNG from different apps, or you can try to save PNG in 8 bit format.

Share to MyApp button in Photos

What does it take to add a menu option to the iPhone's Photos/Camera app similar to the "Share via Facebook" functionality, where a user can take a photo with Camera and push it to my app? And what provisions would I need to make in my ViewController to accomodate the pushed image data?
Thanks.
Simply put, you can't. Apple doesn't allow your app to add functionality to built-in iOS apps.
You will need to build into your app a camera feature that can access the users Photo Library and also add the sharing functionality that you are looking for.

Can I build a mobile website that has access to the iphone camera?

Does webkit have access to the camera API on the iphone? What about other phones? I want to build a mobile website that enables users to click on a button that opens the camera, ask if you want to take a new picture or user an existing one (assume the former), take a picture, confirm the picture is good, then be routed back to website where the new picture is uploaded. is this possible? many thanks!
At this time, this is not possible. You can, however, use a toolkit such as PhoneGap to acheive this.
