iOS Question Camera Upload in Webview crashes app immediately

[Martin Larsen]

I have a webview where the user can upload an image. When you click the Choose button, IOS gives you 3 choices:

• Take Photo or Video
• Photo Library
• Browser

The latter two works fine, but if I choose to take a photo, the app crashes immediately with the following error:

SignalHandler 6
Error occurred on line: 127 (ImageSlider)
Signal - 6

    "0   result               SignalHandler + 120",

)

The line number, here 127 in ImageSlider, is probably not correct. Because if I disable the ImageSlider, the error just happens somewhere else in a completely different module.

Sometimes I see the camera app for half a second or so before the crash. Mostly the app just terminates.

Any help or hints would be appreciated!

Do you have a permission reason line like this in the Project Attributes Region?

#PlistExtra:<key>NSCameraUsageDescription</key><string>Allows you to take a photo or video.</string>

Doh!
Thanks, that did the trick

My next question is then: How can I detect if the user denies the permission? If she does, the app crashes the same way as before.

One of these threads will hopefully lead you to a way:

Check for notification permissions

Hi, Guy I have got a problem relating to checking for notification permissions - and would be grateful for some help. Basically, I have written some code based about previous post, see https://www.b4x.com/android/forum/threads/notification-allowed.111064/ which includes a response from Erel on...

Notification allowed

Hi is there a way to check if the user has enabled notifications or not and if not to be taken to the setting page to enable notification or to have another pop up.
