[Nguyễn Ngọc Anh Vũ]

Bug Report

To Do First

• Did you try latest release?
• Did you try master?
• Did you look for existing matching issues?

Platforms

iOS

Versions

• Android:
• iOS: Any iOS 14+
• react-native-camera: 4.2.1
• react-native: 0.63.3
• react: 16.13.1

Description/Current Behaviour

When used prop imageType on iOS for takePictureAsync, app crash.
The error doesn't show on React Native Debugger, but I found it in XCode Console:

Fatal Exception: NSInvalidArgumentException
-[__NSCFNumber isEqualToString:]: unrecognized selector sent to instance 0x90d1138348a582b1

I believe the error is around these lines in RNCamera.m, line 838-843

NSString *imageExtension = @".jpg";Í
if ([options[@"imageType"] isEqualToString:@"png"]) {
    imageType = RNCameraImageTypePNG;
    imageTypeIdentifier = kUTTypePNG;
    imageExtension = @".png";
}

Expected Behaviour

Take picture success, app doesn't crash

Steps to Reproduce

const response = await cameraRef.current.takePictureAsync({
  width: deviceWidth,
  fixOrientation: true,
  forceUpOrientation: true,
  orientation: RNCamera.Constants.Orientation.portrait,
  imageType: RNCamera.Constants.ImageType.jpeg,
});
