How to pass two images picked from UIImagePickerController to another ViewController - ios

Question

I have two images in one view controller which have been picked with UIImagePickerController:
ChoosePhotosViewController.h
#interface PickPhotosViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
#property (strong, nonatomic) IBOutlet UIImageView *pickedImage1; // image 1
#property (strong, nonatomic) IBOutlet UIImag8eView *pickedImage2; // image 2
- (IBAction)pickImage1:(id)sender; // button that picks up the first image
- (IBAction)pickImage2:(id)sender; // button that picks up the seconds image
- (IBAction)nextButton:(id)sender;
in implementation file - ChoosePhotosViewController.m
#implementation PickPhotosViewController
#synthesize pickedImage1, pickedImage2;
for each button I wrote a code which invokes action sheet with a list of actions:
-(IBAction)pickImage1:(id)sender {
[[NSUserDefaults standardUserDefaults] setInteger:CurrentImageCategoryImage1 forKey:#"currentImageCategory"];
[[NSUserDefaults standardUserDefaults] synchronize];
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Choose image one" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Choose existing photo", #"Take new photo", nil];
[actionSheet showInView:self.view];
}
There are two actions - take photo from camera air upload from library:
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
else if (buttonIndex == 1) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
}
The similar algorithm for the second button. Then in UIImagePickerController method I wrote;
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary*)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
if([[NSUserDefaults standardUserDefaults] integerForKey:#"currentImageCategory"] ==CurrentImageCategoryImage1)
{
self.pickedImage1.image = chosenImage;
}
else if([[NSUserDefaults standardUserDefaults] integerForKey:#"currentImageCategory"] ==CurrentImageCategoryImage2)
{
self.pickedImage2.image = chosenImage;
}
}
Then I need to display these two images in the next viewController when I click button “next”. I work with storyboards, that is why I wrote prepareForSegue method:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#“next"]) {
TypeTextViewController *transferedImage = [segue destinationViewController];
transferedImage.imageWithText1 = pickedImage1;
}
}
where imageWithText1 is a UIImageView and declared in TypeTextViewController.h, but When I click button images don’t appear in the TypeTextViewController.
Where is a problem?

Answer 1

You want to create NSMutableArray and then this two Images add into this Array.And then you have to pass this NSMutableArray to Another View Controller.
Hope this is helpfull.

Answer 2

I dont think you can pass a UIImageView from one VC to another VC. I think we can only pass UIImage and not UIImageView. Try this.. But im not sure.
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#“next"])
{
TypeTextViewController *transferedImage = [segue destinationViewController];
transferedImage.imageWithText1.image = pickedImage1.image;
}
}

// pass Image one view to other view:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
[self dismissViewControllerAnimated:YES completion:^
{
color_ViewController*secondview=[[UIStoryboard storyboardWithName:#"Main" bundle:nil]instantiateViewControllerWithIdentifier:#"color_ViewController"];
secondview.b_image=image;
[[NSUserDefaults standardUserDefaults ]setInteger:1 forKey:#"123"];
[[self navigationController] pushViewController:secondview animated:YES];
}];
}
