I have an app with which I want to choose photo or video from photo galley and upload them to server. This works fine for ios 4. The code is as follows:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
image_selected = FALSE;
video_selected = FALSE;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage,(NSString *)kUTTypeMovie, nil];
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
image_selected = TRUE;
imageFrame = [info objectForKey:UIImagePickerControllerOriginalImage];
NSLog(#"image1 has %#", imageFrame);
[image setImage:imageFrame];
}else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
video_selected = TRUE;
videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSLog(#"video has %#", videoURL);
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc]initWithContentURL:videoURL];
videoFrame = [[mp thumbnailImageAtTime:0.0 timeOption:MPMovieTimeOptionNearestKeyFrame]retain];
[image setImage:videoFrame];
[mp release];
}
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
However this does not work in ios 5 (simulator or device). The application freezes as and when the choose button in photo library is selected.
Any help in this regard is much needed.

This code is working fine on ios 10 but it crashes on ios 11 when I present picker
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
pickerController.delegate = self;
pickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
pickerController.showsCameraControls = YES;
pickerController.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie]; // kUTTypeMovie is actually an NSString.

hello I need to build app that record video from iPhone camera.
I search in the net and not found notting that works in iOS 9.
I get this code from this git project :
https://github.com/versluis/Video-Recorder
This code open camera but not allow Me to take a video.
- (IBAction)recordButton:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *picker = [[UIImagePickerController alloc]init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
picker.allowsEditing = NO;
NSArray *mediaTypes = [[NSArray alloc]initWithObjects:(NSString *)kUTTypeMovie, nil];
picker.mediaTypes = mediaTypes;
[self presentViewController:picker animated:YES completion:nil];
} else {
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil message:#"I'm afraid there's no camera on this device!" delegate:nil cancelButtonTitle:#"Dang!" otherButtonTitles:nil, nil];
[alertView show];
}
}
- (IBAction)playbackButton:(id)sender {
// pick a video from the documents directory
NSURL *video = [self grabFileURL:#"video.mov"];
// create a movie player view controller
MPMoviePlayerViewController * controller = [[MPMoviePlayerViewController alloc]initWithContentURL:video];
[controller.moviePlayer prepareToPlay];
[controller.moviePlayer play];
// and present it
[self presentMoviePlayerViewControllerAnimated:controller];
}
#pragma mark - Delegate Methods
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
// user hit cancel
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// grab our movie URL
NSURL *chosenMovie = [info objectForKey:UIImagePickerControllerMediaURL];
// save it to the documents directory
NSURL *fileURL = [self grabFileURL:#"video.mov"];
NSData *movieData = [NSData dataWithContentsOfURL:chosenMovie];
[movieData writeToURL:fileURL atomically:YES];
// save it to the Camera Roll
UISaveVideoAtPathToSavedPhotosAlbum([chosenMovie path], nil, nil, nil);
// and dismiss the picker
[self dismissViewControllerAnimated:YES completion:nil];
}
- (NSURL*)grabFileURL:(NSString *)fileName {
// find Documents directory
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
// append a file name to it
documentsURL = [documentsURL URLByAppendingPathComponent:fileName];
return documentsURL;
}
Ray gave pretty good tutorial about this. Hope it helped.
I'm trying to build an app in which I'm able to capture image with camera and save to gallery. But I'm unable to get the file name of image. If I select image from camera roll, then I'm able to get file name of selected image.But when I capture image with camera in my app, It returns file name "null". Here is my code to save and select image from gallery using UIImagePickerController
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *chosenImage = [self scaleAndRotateImage:[info valueForKey:UIImagePickerControllerOriginalImage]];
NSString *mediaType = info[UIImagePickerControllerMediaType];
self.userProfileImage.image = chosenImage;
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
UIImage *image = info[UIImagePickerControllerOriginalImage];
if (newMedia)
UIImageWriteToSavedPhotosAlbum(image,
self,
#selector(image:finishedSavingWithError:contextInfo:),
nil);
}
imageRotation=[NSString stringWithFormat:#"%f %f %f",acos (self.userProfileImage.transform.a), asin (self.userProfileImage.transform.b), atan2(self.userProfileImage.transform.b, self.userProfileImage.transform.a)];
CGFloat angle = [(NSNumber *)[self.userProfileImage valueForKeyPath:#"layer.transform.rotation.z"] floatValue];
NSLog(#"%f", angle);
NSURL *referenceURL = [info objectForKey:UIImagePickerControllerReferenceURL];
ALAssetsLibrary *assetLibrary = [ALAssetsLibrary new];
[assetLibrary assetForURL:referenceURL
resultBlock:^(ALAsset *asset) {
ALAssetRepresentation *assetRep = [asset defaultRepresentation];
fileName = [assetRep filename];
NSLog(#"File name = %#", fileName);
}
failureBlock:^(NSError *error) {
NSLog(#"%#", error);
}];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[picker dismissViewControllerAnimated:YES completion:nil];
imageChanged=TRUE;
}
And this code to save captured image
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
UIAlertView *alert;
//NSLog(#"Image:%#", image);
if (error) {
alert = [[UIAlertView alloc] initWithTitle:#"Error!"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
I'm stuck at the point that how can I get file name of captured image.
What wrong I'm doing in my code ? Please suggest me any correction or solution. Any help would be appreciated . Thanks in advance

how to get path of picture taken by camera ios swift
The image you have taken is not saved and has not any name yet. You need to save the image before you can get the path for the image. That´s why it returns nil.
I stored images in an NSMutableArray, and now I'm trying to get them to show up in viewDidLoad. I tried calling initWithContentsOfFile, but that doesn't seem to work. This is how the code looks:
imageView.image = [[UIImage alloc] initWithContentsOfFile:[self.array objectAtIndex:0]];
I'm not sure what I should use instead of initWithContentsOfFile to have the saved images load, I'm not even sure if I can save images in a plist through user defaults. I've been researching it for awhile now to no avail. Any help is much appreciated, thanks!
EDIT: Here is additional code:
- (IBAction)grabImage {
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
_popover = [[UIPopoverController alloc] initWithContentViewController:imgPicker];
[_popover presentPopoverFromRect:self.imageView.bounds inView:self.imageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
else {
[self presentModalViewController:imgPicker animated:YES];
}
[self.imgPicker resignFirstResponder];
}
// Sets the image in the UIImageView
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo {
if (imageView.image == nil) {
imageView.image = img;
[self.array addObject:imageView.image];
[picker dismissModalViewControllerAnimated:YES];
[self.popover dismissPopoverAnimated:YES];
return;
}
if (imageView2.image == nil) {
imageView2.image = img;
NSLog(#"The image is a %#", imageView);
[self.array addObject:imageView2.image];
[picker dismissModalViewControllerAnimated:YES];
[self.popover dismissPopoverAnimated:YES];
return;
}
if (imageView3.image == nil) {
imageView3.image = img;
[self.array addObject:imageView3.image];
[picker dismissModalViewControllerAnimated:YES];
[self.popover dismissPopoverAnimated:YES];
return;
}
}
- (void)applicationDidEnterBackground:(UIApplication*)application {
NSLog(#"Image on didenterbackground: %#", imageView);
[self.array addObject:imageView.image];
[self.array addObject:imageView2.image];
[self.array addObject:imageView3.image];
[self.user setObject:self.array forKey:#"images"];
[user synchronize];
}
- (void)viewDidLoad
{
self.user = [NSUserDefaults standardUserDefaults];
NSLog(#"It is %#", self.user);
self.array = [[self.user objectForKey:#"images"]mutableCopy];
imageView.image = [[UIImage alloc] initWithContentsOfFile:[self.array objectAtIndex:0]];
imageView2.image = [[UIImage alloc] initWithContentsOfFile:[self.array objectAtIndex:1]];
imageView3.image = [[UIImage alloc] initWithContentsOfFile:[self.array objectAtIndex:2]];
UIApplication *app = [UIApplication sharedApplication];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(applicationDidEnterBackground:)
name:UIApplicationDidEnterBackgroundNotification
object:app];
backToGalleryButton.hidden = YES;
tapToDeleteLabel.hidden = YES;
deleteButton1.hidden = YES;
[super viewDidLoad];
}
EDIT: This is how I'm tagging the images and deleting them based upon their tags:
- (IBAction)deleteButtonPressed:(id)sender {
NSLog(#"Sender is %#", sender);
UIAlertView *deleteAlertView = [[UIAlertView alloc] initWithTitle:#"Delete"
message:#"Are you sure you want to delete this photo?"
delegate:self
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes", nil];
[deleteAlertView show];
int imageIndex = ((UIButton *)sender).tag;
deleteAlertView.tag = imageIndex;
}
- (UIImageView *)viewForTag:(NSInteger)tag {
UIImageView *found = nil;
for (UIImageView *view in self.array) {
if (tag == view.tag) {
found = view;
break;
}
}
return found;
}
- (void)alertView: (UIAlertView *) alertView
clickedButtonAtIndex: (NSInteger) buttonIndex
{
if (buttonIndex != [alertView cancelButtonIndex]) {
NSLog(#"User Clicked Yes. Deleting index %d of %d", alertView.tag, [array count]);
NSLog(#"The tag is %i", alertView.tag);
UIImageView *view = [self viewForTag:alertView.tag];
if (view) {
[self.array removeObject:view];
}
NSLog(#"After deleting item, array count = %d", [array count]);
NSLog(#"Returned view is :%#, in view: %#", [self.view viewWithTag:alertView.tag], self.view);
((UIImageView *)[self.view viewWithTag:alertView.tag]).image =nil;
}
[self.user setObject:self.array forKey:#"images"];
}
The problem is that you can't store images in a property list, which is what you're trying to do when you save it in the user defaults. You need to use an archiver to convert the image to an NSData object which you can store.
It looks like you're not passing a valid image path to the initializer method. Make sure the path is correct, and that it includes the image extension.
Really, though, you shouldn't be calling initWithContentsOfFile: in this case, because UIImageView's image property retains the image when you set it. That will usually lead to a memory leak (unless you're using automatic reference counting). Use one of the static initializers instead, such as imageNamed:, which has the added bonuses of using the system cache and also automatically loading the correct version of the image based on the characteristics of the device (for instance, it will load a higher resolution variant of the image if the device has a retina display).
Hi i want the images what ever saved in photo library.Using assert library can i get complete images stored in photo library.If yes,can anyone please tell me the code for that.Thanks in advance.
Super easy to do!
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[imagePicker setDelegate:self];
[self presentModalViewController:imagePicker animated:YES];
and
- (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];
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
[customImageView setImage:image];
customImageView.contentMode = UIViewContentModeScaleAspectFill;
}
got this code from stackoverflow, didn't save the URL, sorry.
