I have this method for when the user opens their camera roll. I have the allows editing set to YES but when on the editing screen the square crop box only appears on iphone and not iPad. What am I missing?
- (void)useCameraRoll
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum])
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = #[(NSString *) kUTTypeImage];
imagePicker.allowsEditing = YES;
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone)
{
[self presentViewController:imagePicker animated:YES completion:nil];
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
[self setModalPresentationStyle:UIModalPresentationFormSheet];
[self.navigationController presentViewController:imagePicker animated:YES completion:nil];
});
}
}
}
And delegate method
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = info[UIImagePickerControllerMediaType];
[self dismissViewControllerAnimated:YES completion:nil];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
theCustomImage = info[UIImagePickerControllerEditedImage];
[self roundedCorners];
[self placeImage:theCustomImage];
customImage = true;
UIImageWriteToSavedPhotosAlbum(theCustomImage, self, #selector(image:finishedSavingWithError:contextInfo:), nil);
}
}

Works Fine Try
I have trouble figuring out, how to capture photo and record video on same view because methods used for both are same.
I tried it but still not clear whether code is correct or not.
I shall be thankful if someone would just review the code and tell me it's correct or not.
Below is the code :
- (IBAction)CaptureRubbish:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)RecordRubbish:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
[self presentViewController:picker animated:YES completion:NULL];
}
}
- (void)videoPlayBackDidFinish:(NSNotification *)notification {
[[NSNotificationCenter defaultCenter]removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
// Stop the video player and remove it from view
[self.videoController stop];
[self.videoController.view removeFromSuperview];
self.videoController = nil;
// Display a message
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"Video Playback" message:#"Just finished the video playback. The video is now removed." preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okayAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:okayAction];
[self presentViewController:alertController animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self->ImageVIew.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
self.videoURL = info[UIImagePickerControllerMediaURL];
[picker dismissViewControllerAnimated:YES completion:NULL];
self.videoController = [[MPMoviePlayerController alloc] init];
[self.videoController setContentURL:self.videoURL];
[self.videoController.view setFrame:CGRectMake (0, 0, self.view.frame.size.width, 460)];
[self.view addSubview:self.videoController.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.videoController];
[self.videoController play];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
if (info[UIImagePickerControllerMediaType] == (NSString *) kUTTypeImage) {

}

I Would create a app with camera but when i write this code in ImageViewController.m

-(BOOL) launchCameraControllerFromViewController: (UIViewController*) controller usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>)

It says you have not method at all. Try changing to this (note the braces after method name and after all code):
-(BOOL) launchCameraControllerFromViewController: (UIViewController*) controller usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>) delegate{
BOOL truefalse = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]; //variable to check whether there is a camera available
//if there is a camera, the delegate passed exists, and the controller passed exists, proceed on, otherwise don't go any further
if (!truefalse || (delegate == nil) || (controller == nil)) {
NSLog(#"no can do, delegate/camera/view controller doesn't exist!");
return NO;
}
UIImagePickerController *cameraController = [[UIImagePickerController alloc] init];
cameraController.sourceType = UIImagePickerControllerSourceTypeCamera;
cameraController.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
cameraController.allowsEditing = NO;
cameraController.delegate = delegate;
}
Can You Try this.

I am trying to push a view controller (for extra editing) from UIImagePickerController after user has selected an image.
It is successfully pushed.
But when that view controller is popped and user return to the editing screen, the editing screen is no longer interactable. Does anyone know what is the problem.
-(void)didTapBtn:(id)sender
{
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
self.picker.delegate = self;
self.picker.allowsEditing = YES;
[self presentViewController:self.picker animated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
if (image == nil) {
image = [info objectForKey:UIImagePickerControllerOriginalImage];
}
if (image == nil) {
return;
}
self.test = [[BTTestViewController alloc] init];
self.test.delegate = self;
[self.picker pushViewController:self.test animated:YES];
}
//Called by BTTestViewController
-(void)didCancel
{
[self.picker popViewControllerAnimated:YES];
}
try this one it work in my application:
UIImagePickerController *imagePicker;//put it in .h file
put it in .m file
imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"STEP-BY-STEP-STORY!" message: #"Camera is not available" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *pickedImage = [info objectForKey:UIImagePickerControllerEditedImage];
imageData.image =[self resizeImage:imageData.image width:200 height:200];
[picker dismissViewControllerAnimated:YES completion:nil];
iphone_filtersViewController *nav=[[iphone_filtersViewController alloc]initWithNibName:#"iphone_filtersViewController" bundle:nil];
[self.navigationController pushViewController:nav animated:YES];
}

{
// release Picker
[picker dismissViewControllerAnimated:YES completion:nil];
}
// iphone_filtersViewController method

}
may be it will help.
I've 2 UIButtons, I want both buttons to pick an image, button1 is setting an image to imageview1 and button2 to imageView2. I now created button1 which picks an image and set imageView1 to that image, but if I'm creating button2, I don't now what I have to do in:
- (IBAction)chooseImage1:(id)sender {
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePicker animated:YES completion:nil];
}
- (IBAction)chooseImage2:(id)sender {
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePicker animated:YES completion:nil];
}
UIImage *image;
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *mediaURL;
mediaURL = (NSURL *)[info valueForKey:UIImagePickerControllerMediaURL];
image = (UIImage *)[info valueForKey:UIImagePickerControllerOriginalImage];
imageView1.image=image;
[picker dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];
}
Create an index in your .h file. Something like
NSUInteger *selectedImageIndex;
And in your .m file :
- (void)showImagePicker:(UIImagePickerControllerSourceType)source{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = source;
ipc.allowsEditing = YES;
ipc.delegate = self;
[self presentModalViewController:ipc animated:YES];
}
- (IBAction)chooseImage1:(id)sender {
selectedImageIndex = 1;
[self showImagePicker:UIImagePickerControllerSourceTypePhotoLibrary];
}
- (IBAction)chooseImage2:(id)sender {
selectedImageIndex = 2;
[self showImagePicker:UIImagePickerControllerSourceTypePhotoLibrary];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *img = [info objectForKey:#"UIImagePickerControllerEditedImage"];
if (!img)
img = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
if (selectedImageIndex == 1)
imageView1.image=img;
else
imageView2.image = img;
[picker dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];
}
But then again, this is just one way to do it.
