UIImagePickerController is a view controller that is used for choosing items from the user’s media library(like- images, videos)
It is managing the user interface when we choose the picture or video from the library.
Now, we are going to use UIImagePickerController in a project.
First, we create an instance for ImagePickerController and add protocols for adopting a protocol to properly use UIImagePickerController
Now, we will create the action for the Add Image Button and here we call UIImagePickerController
We need to set whether the image picker wants to allow editing or not and also need to set source type.
You can set the source type .photoLibarary or .savedPhotosAlbum.
The basic difference between photoLibrary and savedPhotosAlbum is .photoLibrary gives access to users of any photos available on the device, with albums, and camera roll.
The .savedPhotosAlbum save images locally on your device but has no access to albums or any of the other views.
Now, we need to implement the delegate method “imagePickerController:didFinishPickingMediaWithInfo:” .
At last, we will dismiss the view controller that was presented before
The UIImagePickerController makes it easy for users to select images from their device and keeps the user experience consistent with the other apps that also use it.
