how do I set a UICollectionViewCell to be used as a button , that also repeats itself when the function is done.
I want to use the cell as a button to add images from my photo library.
The code extract is the function of the barbutton item I used to add images.
- (IBAction)buttonTapped:(id)sender {
_picker = [[UIImagePickerController alloc] init];
_picker.delegate = self;
_picker.allowsEditing = NO;
_picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:_picker animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
[_images addObject:image];
[self saveNewImageToDb:image];
[self dismissViewControllerAnimated:_picker completion:^{
[_collectionView reloadData];
}];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:_picker completion:nil];
}
You can implement this function :
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
// something you do as function "buttonTapped"
}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"Selected cell = %d",indexPath.item);
_picker = [[UIImagePickerController alloc] init];
_picker.delegate = self;
_picker.allowsEditing = NO;
_picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:_picker animated:YES completion:nil];
}

Want to add the camera capture images added in array and load that array in collection view display the all the images
///here i get the capture image in picker
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// in this part how can add the camera capture image in array
// and load that array value in collection view..
}
help me how to achieve this...
I have not tested what I am about to write, but you could try this:
-(void)viewDidLoad {
//declare before NSMutableArray *_mutableArray;
_mutableArray = [[NSMutableArray alloc] init];
}
...
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
//dismiss UIImagePickerController
[picker dismissViewControllerAnimated:YES completion:Nil];
//take image from info
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
//store image into NSMutableArray
[_mutableArray addObject:image];
//reload collectionView
[self.collectionView reloadData];
}
and in collectionView cellForItemAtIndexPath
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
//this is a custom CollectionViewCell
CollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"Cell" forIndexPath:indexPath];
cell.imageA.image = [_mutableArray objectAtIndex:indexPath.row];
return cell;
}
I have two UI Buttons in my view controller, and an imageview. One button has the user pick a picture from the photo library and add it to the UIImage. The other has the user take a new picture and show it in the UIimage.
The libraryButton and actions all work, however when I add the cameraButton code I get an error since I'm using the same "startcameracontrollerfromviewcontroller" My question is can I simply change this to startcameracontrolfromviewcontroller? or is there something else I would have to change.
#pragma mark - Button Actions
- (IBAction)libraryButton:(id)sender {
[self startCameraControllerFromViewController:self usingDelegate:self];
}
#pragma mark - UIImagePickerControllerDelegate methods
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera] == NO) || (delegate == nil) || (controller == nil))
return NO;
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
cameraUI.delegate = delegate;
[controller presentViewController:cameraUI animated:YES completion:nil];
return YES;
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage * image = info[UIImagePickerControllerOriginalImage];
_imageView.image = image;
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:nil];
}
#pragma mark - Camera Button
- (IBAction)cameraButton:(id)sender {
[self startCameraControllerFromViewController:self usingDelegate:self];
}
#pragma mark - Camera Delegate methods
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera] == NO) || (delegate == nil) || (controller == nil))
return NO;
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
cameraUI.delegate = delegate;
[controller presentViewController:cameraUI animated:YES completion:nil];
return YES;
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage * image = info[UIImagePickerControllerOriginalImage];
_imageView.image = image;
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:nil];
}
#end
You can call the same method from each IBAction passing it a different value that will be used to determine the image pickers source type - (for this example I'm not passing in the presenting view controller or delegate, but this could be easily adapted to implement)
- (IBAction)libraryButton:(id)sender {
[self showImagePickerForSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}
- (IBAction)cameraButton:(id)sender {
[self showImagePickerForSourceType:UIImagePickerControllerSourceTypeCamera];
}
- (void)showImagePickerForSourceType:(UIImagePickerControllerSourceType)sourceType {
// start config here....
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
// set the source type here
imagePickerController.sourceType = sourceType;
// do any extra setting up... present controller...
}
I suggest looking at this sample code provided by Apple - Using UIImagePickerController to Select Pictures and Take Photos
please help to push added photo in the frame of UIImageView. The photo doesn't fit in the frame. I have made all the same like in the "IOS Programming: The Big Nerd Ranch Guide" chapter 12 "Camera". Before adding photo: https://www.dropbox.com/s/o0uypvspuhvlkm2/Screen%20Shot%202013-10-27%20at%205.08.39%20PM.jpg After adding: https://www.dropbox.com/s/u6qffb1l941cb0v/Screen%20Shot%202013-10-27%20at%205.09.02%20PM.jpg I've tried setContentMode for UIImageView – doesn't works. This is my code:
#pragma mark UIActionSheetDelegate
- (IBAction)displayActionSheet:(id)sender
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Take photo", #"Choose photo from gallery", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex) {
case 0:
[self takePhoto];
break;
case 1:
[self choosePhoto];
break;
}
}
#pragma mark UIImagePickerControllerDelegate
- (void)takePhoto {
UIImagePickerController *pickerControllerTakePhoto = [[UIImagePickerController alloc] init];
[pickerControllerTakePhoto setSourceType:UIImagePickerControllerSourceTypeCamera];
[pickerControllerTakePhoto setDelegate:self];
[self presentViewController:pickerControllerTakePhoto animated:YES completion:nil];
}
- (void)choosePhoto {
UIImagePickerController *pickerControllerChoosePhoto = [[UIImagePickerController alloc] init];
[pickerControllerChoosePhoto setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[pickerControllerChoosePhoto setDelegate:self];
[self presentViewController:pickerControllerChoosePhoto animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *myPhoto = [info objectForKey:UIImagePickerControllerOriginalImage];
[photoView setImage:myPhoto];
[self dismissViewControllerAnimated:YES completion:NULL];
}
My 'plus' or 'add' button calls action sheet with dialog, so I choose the photo from gallery and result is like on second screenshot.
Set the image views properties:
imageView.clipsToBounds = YES;
imageView.contentMode = UIViewContentModeScaleAspectFill;
Both can be set in Interface Builder.
So I've found the line of code that disturbed me, this all because of my custom cells which I put in order to my tableview:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
if (indexPath.row == 0) {
photoView = (UIImageView *)[photoCell viewWithTag:1]; // this is the first custom cell in my tableview and this line which I put on the model of the book isn't needed
cell = photoCell;

I'm trying to implement MWPhotoBrowser in my project. I've added all the delegates, but it still will not display the photo.
Here's my didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"MWPhotoBrowserSegue" sender:self]
}
This is my segue method:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue identifier] isEqualToString:#"MWPhotoBorwserSegue"])
{
photoBrowser = [[MWPhotoBrowser alloc]initWithDelegate:self];
UINavigationController * nc = [[UINavigationController alloc]initWithRootViewController:photoBrowser];
nc.modalTransitionStyle = UIModalTransitionStyleCrossDisolve;
[photos addObject:[MWPhoto photoWithImage:[UIImage imageNamed:#"picasa.jpg"]];
[photoBrowser setCurrentPhotoIndex:0];
[self.navigationController presentViewController:nc animated:YES completion:nil];
}
}
The #ofPhotosInBrowser:
-(NSUInteger)numberOfPhotosInPhotoBrowser:(MWPhotoBrowser *)photoBrowser
{
return self.photos.count;
}
photoAtIndex:
- (MWPhoto *)photoBrowser:(MWPhotoBrowser *)photoBrowser photoAtIndex:(NSUInteger)index {
if (index < self.photos.count)
return [self.photos objectAtIndex:index];
return nil;
}
Here's what I get after the didSelectRowAtIndexPath: is called:
Edit for Solution:
MWPhotoBrowser will not display a photo unless you put self.title in the initWithStyle: method. I also forgot to add the viewWillDisappear and viewWillAppear
I think u need to call reload data on it. Check Mwphotobrowser.h for proper way to do it.
try this [[NSOperationQueue mainQueue] addOperationWithBlock:^{
[self presentViewController:yourNewNavigationController animated:YES completion:nil];
}];
-(IBAction)TakePhoto {
picker = [[UIImagePickerController alloc]init];
picker.delegate = self;
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
[self presentedViewController:picker animated:YES completion:nil];
}
- (IBAction)ChooseExisting {
picker2 = [[UIImagePickerController alloc]init];
picker2.delegate = self;
[picker2 setSourceType:UIImagePickerControllerSourceTypeCamera];
[self presentedViewController:picker2 animated:YES completion:nil];
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
image = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageview setImage:image];
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:NULL];
When I try to run this app I the
[self presentedViewController:picker animated:YES completion:nil];
Gets highlighted in red saying No visible #interface for ViewController Declares the sector presentedviewcontroller:animated :completion :
My .h file is
#interface ViewController : UIViewController <UIImagePickerControllerDelegate,
UINavigationControllerDelegate> {
UIImagePickerController *picker;
UIImagePickerController *picker2;
UIImage *image;
IBOutlet UIImageView *imageview;
}
- (IBAction)TakePhoto;
- (IBAction)ChooseExisting;
You have a typo: presentedViewController instead of presentViewController on the line
[self presentedViewController:picker animated:YES completion:nil];
(in more than one place)
