I am developing a chat app. In my app when I click attachement button, two options should come.
1) images/videos captured by the device camera(not capturing image at that time. Fetch images taken by the camera that is stored in the device)
2) images/videos downloaded from the web or other medias
Is there any way to fetch images/videos according to the above given criteria preferably using assets library
class YourController : UIViewController,UINavigationControllerDelegate, UIImagePickerControllerDelegate, UIActionSheetDelegate,UIPopoverPresentationControllerDelegate
{
override func viewDidLoad() {
super.viewDidLoad()
}
func takePhotoByGalleryOrCamera(){
//MAark Take picture from gallery and camera
//image picker controller to use take image
// uialert controller to make action
let imageController = UIImagePickerController()
imageController.editing = false
imageController.delegate = self;
let alert = UIAlertController(title: "", message: "Profile Image Selctor", preferredStyle: UIAlertControllerStyle.ActionSheet)
let libButton = UIAlertAction(title: "Select photo from library", style: UIAlertActionStyle.Default) { (alert) -> Void in
imageController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
self.presentViewController(imageController, animated: true, completion: nil)
}
if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
let cameraButton = UIAlertAction(title: "Take a picture", style: UIAlertActionStyle.Default) { (alert) -> Void in
print("Take Photo")
imageController.sourceType = UIImagePickerControllerSourceType.Camera
self.presentViewController(imageController, animated: true, completion: nil)
}
alert.addAction(cameraButton)
} else {
print("Camera not available")
}
let cancelButton = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) { (alert) -> Void in
print("Cancel Pressed")
}
alert.addAction(libButton)
alert.addAction(cancelButton)
if UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Pad {
alert.modalPresentationStyle = UIModalPresentationStyle.Popover;
// alert.transitioningDelegate = self;
alert.popoverPresentationController!.sourceView = self.view;
alert.popoverPresentationController!.sourceRect = CGRectMake(0, SizeUtil.screenHeight(), SizeUtil.screenWidth(), SizeUtil.screenHeight()*0.4)
alert.popoverPresentationController!.delegate = self;
self.presentViewController(alert, animated: true, completion: nil)
} else {
self.presentViewController(alert, animated: true, completion: nil)
}
}
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return UIModalPresentationStyle.Popover
}
//image picker Delegate
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
self.dismissViewControllerAnimated(true, completion: nil)
let header = profileTableView.headerViewForSection(0) as! ProfileHeaderView
header.btnImage.setImage(image, forState: UIControlState.Normal)
_userProfileImage = image
}
}
