Description

The ShareSheet sample shows how to use standard actions in order take a picture with the Camera Application of your iOS or Android device, and share it with other services. The sample uses the TActionList component with two standard actions:

• TTakePhotoFromCameraAction to open the camera application on your iOS or Android device, take a picture and retrieve the taken image to display it on your FireMonkey form.
• TShowShareSheetAction to share the picture with other services (for example, in social networks, by email or Bluetooth).

Classes

TShareSheetForm is the main form that represents the main window of the sample. It contains the following components:

• A TActionList object with two standard actions.
  • A TTakePhotoFromCamera action.
  • A TShowShareSheet action.
• A TImage object.
• Two ToolBar objects:
  • A ToolBar called TopToolBar containing a TLabel object.
  • A ToolBar called BottomToolBar containing two Tbutton objects:
    • A Tbutton called btnTakePhoto.
    • A Tbutton called btnShare.

Implementation

• The sample uses TTakePhotoFromCameraAction to take photos from the camera device.
• The sample uses TImage to display and define 2D image components.
• The sample uses TShowShareSheetAction to share photos with other services.
• The sample uses two Tbuttons that are attached to both actions.

When you run the application, the sample shows a picture and two buttons labeled as Take Photo and Share. The TTakePhotoFromCamera action is attached to the Take Photo button, and the TShowShareSheet action is attached to the Share button.

• If you click the Take Photo button, the camera window is displayed and allows you to choose some camera properties (for example, the camera to be used (front or back)) and take a photo. Once the photo has been taken, the OnDidFinishTaking event assigns the image retrieved from the camera to the TImage component in order to display the photo on your FireMonkey form.
• If you click the Share button, the sharing sheet opens and allows you to share your picture with other services (for example, in social networks, by email or Bluetooth).
