SOS, i need help. I did image uploading on to Amazon S3, and it's working fine, but when I rewrite this code for uploading video it's somethink wrong. Is uploading MOV file, but when i try to play it on browser from url, it's telling me: The image https... cannot be displayed because it contains error.
Here is my code:
- (BOOL) startMediaBrowserFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate{
// Get image picker
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
mediaUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
mediaUI.allowsEditing = YES;
mediaUI.delegate = delegate;
// Display movie files
[controller presentModalViewController:mediaUI animated:YES ];
- (void) imagePickerController: (UIImagePickerController *) picker didFinishPickingMediaWithInfo: (NSDictionary *) info {
[self dismissModalViewControllerAnimated:YES];
UIImage *image = (UIImage*) [info objectForKey:UIImagePickerControllerOriginalImage];
fileName = "anyName.MOV";
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
#try {
S3PutObjectRequest *por = [[S3PutObjectRequest alloc] initWithKey:fileName inBucket:MY_BUCKET];
por.contentType = #"movie/mov";
por.cannedACL = [S3CannedACL publicRead];
por.data = imageData;
[s3 putObject:por];
}
#catch (AmazonClientException *exception) {
NSLog(#"exception %#", exception);
}
}
Pleas point me on my mistake.
Many thanks!!!
Sorted. Problem was with Image object. So I just did get video URL by :
NSURL *image = [info objectForKey:UIImagePickerControllerMediaURL];
Instead
UIImage *image = (UIImage*) [info objectForKey:UIImagePickerControllerOriginalImage];
And then pass NSData from url, so I did replace line
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
to:
NSData *imageData = [NSData dataWithContentsOfURL:image];
And tataaaaaaaa, problem sorted.

I've been searching this forum up and down but I couldn't find what I really need. I want to get raw image data from the camera. Up till now I tried to get the data out of the imageDataSampleBuffer from that method captureStillImageAsynchronouslyFromConnection:completionHandler: and to write it to an NSData object, but that didn't work.
Maybe I'm on the wrong track or maybe I'm just doing it wrong.
What I don't want is for the image to be compressed in any way.
The easy way is to use jpegStillImageNSDataRepresentation: from AVCaptureStillImageOutput, but like I said I don't want it to be compressed.
Thanks!
This is how i do it:
1: I first open the camera using:
- (void)openCamera
{
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
(NSString *) kUTTypeMovie, nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker animated:YES];
}
else {
lblError.text = NSLocalizedStringFromTable(#"noCameraFound", #"Errors", #"");
}
}
When the picture is taken this method gets called:
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// Save and get the path of the image
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
if([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
// Save the image
image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
[library writeImageToSavedPhotosAlbum:[image CGImage] orientation:(ALAssetOrientation)[image imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){
if(!error) {
//Save path and location to database
NSString *pathLocation = [[NSString alloc] initWithFormat:#"%#", assetURL];
} else {
NSLog(#"CameraViewController: Error on saving image : %# {imagePickerController}", error);
}
}];
}
[imagePicker dismissModalViewControllerAnimated:YES];
}
Then with that path i get the picture from the library in FULL resolution (using the "1"):
-(void)preparePicture: (NSString *) filePathPicture{
ALAssetsLibraryAssetForURLResultBlock resultBlock = ^(ALAsset *myasset)
{
if(myasset != nil){
ALAssetRepresentation *assetRep = [myasset defaultRepresentation];
CGImageRef imageRef = [assetRep fullResolutionImage];
if (imageRef) {
NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithCGImage:imageRef], 1);
}
}else {
//error
}
};
ALAssetsLibraryAccessFailureBlock failureBlock = ^(NSError *error)
{
NSString *errorString = [NSString stringWithFormat:#"can't get image, %#",[error localizedDescription]];
NSLog(#"%#", errorString);
};
if(filePathPicture && [filePathPicture length])
{
NSURL *assetUrl = [NSURL URLWithString:filePathPicture];
ALAssetsLibrary *assetslibrary = [[ALAssetsLibrary alloc] init];
[assetslibrary assetForURL:assetUrl
resultBlock:resultBlock
failureBlock:failureBlock];
}
}
Hope this helps you a bit further :-).
I'm using an imagePickerController to replace my existing images inside my view. The function works within the same IB-file. However I'd like to load the chosen image in another IB-File as well. I think that the solution is to give a name to the image when saved. After it is saved I'd like to call the image (by name) from my memory within my other IB-file.
Here's a snippit of code I'm using within the photopicker IB-file
-(IBAction)setPhoto{
image1.image = fotoView.image;
}
-(IBAction)getCameraPicture:(id)sender
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsImageEditing = YES;
picker.sourceType = (sender == takePictureButton) ? UIImagePickerControllerSourceTypeCamera :
UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController: picker animated:YES];
[picker release];
}
-(IBAction)selectExitingPicture
{
if([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController *picker= [[UIImagePickerController alloc]init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
[picker release];
}
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage : (UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
[picker dismissModalViewControllerAnimated:YES];
fotoView.image = image;
NSData* imdata = UIImagePNGRepresentation ( image );
UIImage* im8 = [UIImage imageWithData:imdata];
UIImageWriteToSavedPhotosAlbum(im8, nil, nil, nil);
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *) picker
{
[picker dismissModalViewControllerAnimated:YES];
}
within my other class I'd like to call this image by means of:
if (#some condition){
UIImage *img = [UIImage imageNamed:#"Name of the image.png"];
[image1 setImage:img];
}
Help is greatly appreciated
Method for image picking and saving it to the directory:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo {
[picker dismissModalViewControllerAnimated:YES];
NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *pngFilePath = [NSString stringWithFormat:#"%#/MyName.png",docDir];
NSData *data = [NSData dataWithData:UIImagePNGRepresentation(image)];
[data writeToFile:pngFilePath atomically:YES];
}
Lateron you can call it by using:
NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *pngFilePath = [NSString stringWithFormat:#"%#/MyName.png",docDir];
UIImage *image = [[UIImage alloc] initWithContentsOfFile:pngFilePath];
I am working to capture an image that is returned in 4.0 using
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
// MediaType can be kUTTypeImage or kUTTypeMovie. If it's a movie then you
// can get the URL to the actual file itself. This example only looks for images.
//
NSString* mediaType = [info objectForKey:UIImagePickerControllerMediaType];
// NSString* videoUrl = [info objectForKey:UIImagePickerControllerMediaURL];
// Try getting the edited image first. If it doesn't exist then you get the
// original image.
//
if (CFStringCompare((CFStringRef) mediaType, kUTTypeImage, 0) == kCFCompareEqualTo) {
UIImage* picture = [info objectForKey:UIImagePickerControllerEditedImage];
if (!picture)
picture = [info objectForKey:UIImagePickerControllerOriginalImage];
// **picture is always nil
// info dictionary count = 1
}
}
What is happening is that the info dictionary always returns with a single entry:
{
UIImagePickerControllerMediaType =
"public.image";
which is great, but there is never an image.
I was using a great example from this forum to do this, and I am pretty sure the calls are correct, but never an image.
Thanks in advance!
I know this is many months later, but I struggled with this for hours, and found this same question all over this site and iphonedevsdk.com, but never with a working answer.
To summarize, if the image was picked from the camera roll/photo library it worked fine, but if the image was a new photo take with the camera it never worked. Well, here's how to make it work for both:
You have to dismiss and release the UIImagePickerController before you try to do anything with the info dictionary. To be super-clear:
This DOES NOT work:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
// No good with the edited image (if you allowed editing)
myUIImageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
// AND no good with the original image
myUIImageView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
// AND no doing some other kind of assignment
UIImage *myImage = [info objectForKey:UIImagePickerControllerEditedImage];
[picker dismissModalViewControllerAnimated:YES];
[picker release];
}
In all of those cases the image will be nil.
However, via the magic of releasing the UIImagePickerController first...
This DOES work:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
[picker release];
// Edited image works great (if you allowed editing)
myUIImageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
// AND the original image works great
myUIImageView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
// AND do whatever you want with it, (NSDictionary *)info is fine now
UIImage *myImage = [info objectForKey:UIImagePickerControllerEditedImage];
}
Crazy simple, but that's all there is to it.
whilst Matthew Frederick's answer is most popular and has long been the appropriate response, as of iOS 5.0, apple made available dismissViewControllerAnimated:completion:, to replace the now deprecated (as of iOS 6.0) dismissViewControllerAnimated:.
performing the image info dictionary retrieval in the completion block should hopefully make more sense to all.
to take his example from above, it would now look like:
- (void) imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:^{
// Edited image works great (if you allowed editing)
myUIImageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
// AND the original image works great
myUIImageView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
// AND do whatever you want with it, (NSDictionary *)info is fine now
UIImage *myImage = [info objectForKey:UIImagePickerControllerEditedImage];
}];
}
I've tried all above, but no luck on iPad 6.0/6.1 simulator, however i've found that info contains "UIImagePickerControllerReferenceURL" key and here is my code:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:NULL];
UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage];
if(NULL == image){
[MyImageLoader loadImageFromAssertByUrl:[info objectForKey:#"UIImagePickerControllerReferenceURL"]
completion:^(UIImage* img){
//img not null here
}];
}else{
//image not null here
}
}
and code for loadImageFromAssertByUrl is:
+(void) loadImageFromAssertByUrl:(NSURL *)url completion:(void (^)(UIImage*)) completion{
ALAssetsLibrary *assetLibrary=[[ALAssetsLibrary alloc] init];
[assetLibrary assetForURL:url resultBlock:^(ALAsset *asset) {
ALAssetRepresentation *rep = [asset defaultRepresentation];
Byte *buffer = (Byte*)malloc(rep.size);
NSUInteger buffered = [rep getBytes:buffer fromOffset:0.0 length:rep.size error:nil];
NSData *data = [NSData dataWithBytesNoCopy:buffer length:buffered freeWhenDone:YES];
UIImage* img = [UIImage imageWithData:data];
completion(img);
} failureBlock:^(NSError *err) {
NSLog(#"Error: %#",[err localizedDescription]);
}];
}
There's also a known bug with some versions of XCode and Mountain Lion. Check your console for this message:
2013-01-17 21:36:34.946 3sure-ios[5341:1803] Named service 'com.apple.PersistentURLTranslator.Gatekeeper' not found. assetsd is down or misconfigured. Things will not work the way you expect them to.
It probably won't work if that message appears. Check your app at the actual iOS device.
Nevetheless, restarting both simulator and XCode seems to fix the issue.
I had the same symptoms, but in my case it turned out I had a category on something in the UIImagePickerController hierarchy that overrode "uuid" or "setUUID"? I guess CoreData needs these methods or it gets very, very confused, and the asset library is all CoreData stuff.
use
[[UIImagePickerController alloc] init];
instead of
[[UIImagePickerController alloc] initWithNibName:(NSString *) bundle:(NSBundle *)];
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:NULL];
//Image picker for nil value
UIImage* selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
NSLog(#"my Info :: %#", info);
if(NULL == selectedImage){
UIImage * selectedImage = [PhotoViewController loadImageFromAssertByUrl:[info objectForKey:#"UIImagePickerControllerReferenceURL"]
completion:^(UIImage * selectedImage){
//img not null here
NSLog(#"img2 ::: %#", selectedImage);
uploadImg.image = selectedImage;
[self.view addSubview:PermissionView];
}];
}else{
//image not null here
NSLog(#"Up IMG00 :: %#", uploadImg.image);
NSLog(#"Sel IMG00 :: %#", selectedImage);
uploadImg.image = [selectedImage retain];
NSLog(#"Up IMG22 :: %#", uploadImg.image);
NSLog(#"Sel IMG22 :: %#", selectedImage);
}
}
+(UIImage *) loadImageFromAssertByUrl:(NSURL *)url completion:(void (^)(UIImage*)) completion{
__block UIImage* img;
ALAssetsLibrary *assetLibrary=[[ALAssetsLibrary alloc] init];
[assetLibrary assetForURL:url resultBlock:^(ALAsset *asset) {
ALAssetRepresentation *rep = [asset defaultRepresentation];
Byte *buffer = (Byte*)malloc(rep.size);
NSUInteger buffered = [rep getBytes:buffer fromOffset:0.0 length:rep.size error:nil];
NSData *data = [NSData dataWithBytesNoCopy:buffer length:buffered freeWhenDone:YES];
img = [UIImage imageWithData:data];
completion(img);
NSLog(#"img ::: %#", img);
} failureBlock:^(NSError *err) {
NSLog(#"Error: %#",[err localizedDescription]);
}];
return img;
}
Following Steps needs to be followed:
1) Make UIActionSheet
2) On selection necessary source type - load resrouces
3) didFinishPickingMediaWithInfo - set image from image Dictionary recieved
- (IBAction)actionButtonUpload:(id)sender {
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self
cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Camera",#"Photo Library", nil];
[actionSheet showInView:self.view];
}
#pragma mark -- UIActionSheet Delegate
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
UIAlertView *alert;
switch (buttonIndex) {
case 0:
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {

} else {
alert = [[UIAlertView alloc]initWithTitle:#"Alumnikonnect" message:#"Camera is not available, please select a different media" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}
break;

I am using UIImagePickerController that gives user to be able select an existing photo or use the camera to take an image at that time. And i can show that image in my application with UIImageView.
Now i want to use this ability for movies also. But i couldn't find any way to show the selected movie as an image in my app, just like the Photos app. as you know you can see photos and movies in the same list.

The -thumbnailImageAtTime:timeOption: method of MPMoviePlayerController looks like it might help you get an image to display.
To have the picker view with only movie files
replace
imagePicker.mediaTypes =[UIImagePickerController availableMediaTypesForSourceType:imagePicker.sourceType];
with
picker.mediaTypes = [NSArray arrayWithObject:#"public.movie"];
How can I save an image (like using UIImageWriteToSavedPhotosAlbum() method) with a filename of my choice to the private/var folder?
Kenny, you had the answer! For illustration I always think code is more helpful.
//I do this in the didFinishPickingImage:(UIImage *)img method
NSData* imageData = UIImageJPEGRepresentation(img, 1.0);
//save to the default 100Apple(Camera Roll) folder.
[imageData writeToFile:#"/private/var/mobile/Media/DCIM/100APPLE/customImageFilename.jpg" atomically:NO];
UIImageWriteToSavedPhotosAlbum() is only used for saving to the photos camera roll. To save to a custom folder, you need to convert the UIImage into NSData with UIImageJPEGRepresentation() or UIImagePNGRepresentation(), then save this NSData to anywhere you like.
You can use below code, without use of ALAssetsLibrary...
NSString *fileName;
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:^{
if( [picker sourceType] == UIImagePickerControllerSourceTypeCamera )
{
UIImageWriteToSavedPhotosAlbum(image,nil, nil, nil);
[self performSelector:#selector(GetImageName) withObject:nil afterDelay:0.5];
}
else
{
NSURL *refURL = [info valueForKey:UIImagePickerControllerReferenceURL];
PHFetchResult *result = [PHAsset fetchAssetsWithALAssetURLs:#[refURL] options:nil];
fileName = [[result firstObject] filename];
}
}];
-(void)GetImageName
{
NSString *str =#"";
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.sortDescriptors = #[[NSSortDescriptor sortDescriptorWithKey:#"creationDate" ascending:YES]];
PHFetchResult *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
if (fetchResult != nil && fetchResult.count > 0) {
str = [[fetchResult lastObject] filename];
}
fileName = str;
}
