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.

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.
Just wondering if anybody could help me out identifying and creating an iOS option such as this (http://imgur.com/QSfYavr) when a user clicks on a button, it gives the option to use a camera or choose a picture from photo library. I have researched UIIMAGEPICKER however don't think that is what I am after.
I am using latest Xcode + developing for iOS 7 also.
Thanks.
You can use the following code:
// Set these delegates in the header file
<UIImagePickerControllerDelegate, UINavigationControllerDelegate,UIActionSheetDelegate>
// On Button Action
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Select Face for Perform Dance step"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Camera", #"Select from Library", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
[actionSheet showInView:self.view];
// Action sheet delegate
#pragma mark -
#pragma mark UIActionSheetDelegate
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
int i = buttonIndex;
switch(i)
{
case 0:
{
UIImagePickerController * picker = [[[UIImagePickerController alloc] init] autorelease];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:^{}];
}
break;
case 1:
{
UIImagePickerController * picker = [[[UIImagePickerController alloc] init] autorelease];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:^{}];
}
default:
// Do Nothing.........
break;
}
}
At last handle camera and select from gallery actions:
#pragma mark -
#pragma - mark Selecting Image from Camera and Library
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Picking Image from Camera/ Library
[picker dismissViewControllerAnimated:YES completion:^{}];
self.selectedImage = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
if (!self.selectedImage)
{
return;
}
// Adjusting Image Orientation
NSData *data = UIImagePNGRepresentation(selectedImage);
UIImage *tmp = [UIImage imageWithData:data];
UIImage *fixed = [UIImage imageWithCGImage:tmp.CGImage
scale:selectedImage.scale
orientation:self.selectedImage.imageOrientation];
self.selectedImage = fixed;
}
This code will work on all iOS SDKs 5.x, 6.x, 7.x.
Enjoy. :)
Its UIActionSheet for iOS7, if you updating your app for iOS7 looks for all iOS versions prior to iOS7, here's one already made, you can check it, https://github.com/ianb821/IBActionSheet
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.
[picker dismissModalViewControllerAnimated:YES];
I am have an app that calls UIImagePickerController, and you take video using the controller. After you take the video, I want the video to be saved into the camera roll after clicking use in the UIImagePickerController.
Can you help me?
Oh, and UIImagePickerController comes with the option to switch to video, default photo. I want this to be only video, not photo.
My current code is :
picker.sourceType=UIImagePickerControllerCameraCaptureModeVideo;
picker.mediaTypes=[UIImagePickerController availableMediaTypesForSourceType:picker.sourceType];
Once you have implemented the following delegate method, pressing the 'Use' button will save your recorded video to the camera roll.
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
NSURL *recordedVideoURL= [info objectForKey:UIImagePickerControllerMediaURL];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:recordedVideoURL]) {
[library writeVideoAtPathToSavedPhotosAlbum:recordedVideoURL
completionBlock:^(NSURL *assetURL, NSError *error){}
];
}
[library release];
}
Use the following to set the capture mode to video :
imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
Here is the complete code that I use to launch the image picker for video recording :
UIImagePickerController * imagePickerController = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
imagePickerController.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.showsCameraControls = YES;
imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
imagePickerController.delegate = self;
imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront;
[self presentModalViewController:imagePickerController animated:YES];
}
I was trying to save the video using the absoluteURL of the URL but it didn't work
NSURL *mediaURL = [info objectForKey: UIImagePickerControllerMediaURL];
UISaveVideoAtPathToSavedPhotosAlbum(mediaURL.absoluteString, self, #selector(video:didFinishSavingWithError:contextInfo:), nil);
It finally worked using the path property:
UISaveVideoAtPathToSavedPhotosAlbum([mediaURL path], self, #selector(video:didFinishSavingWithError:contextInfo:), nil);
Hope it helps anyone.
From the UIImagePickerControllerDelegate class reference:
To save a still image to the user’s Camera Roll album, call the
UIImageWriteToSavedPhotosAlbum function from within the body of the
imagePickerController:didFinishPickingMediaWithInfo: method. To save a
movie to the user’s Camera Roll album, instead call the
UISaveVideoAtPathToSavedPhotosAlbum function. These functions,
described in UIKit Function Reference, save the image or movie only;
they do not save metadata.
Your UIImagePickerControllerDelegate may look something like this...
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = [info objectForKey:#"mediaType"];
if (![mediaType isEqualToString:kUTTypeMovie])
return;
NSURL *mediaURL = [info objectForKey:#"mediaURL"];
UISaveVideoAtPathToSavedPhotosAlbum(mediaURL.absoluteString, self, #selector(video:didFinishSavingWithError:contextInfo:), NULL);
}
- (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo: (void *)contextInfo
{
if (!videoPath && error)
{
NSLog(#"Error saving video to saved photos roll: %#, %#", error, [error userInfo]);
// Handle error;
return;
}
// Video was saved properly. UI may need to be updated here.
}
Notice that I've implemented the completion selector for UISaveVideoToSavedPhotosAlbum(). If it were to fail for any reason, the error would be reported here and you can then handle it appropriately.
Alright, this problem is rather bizarre, and I'm 99% positive at this point it's not a retain/release error. Basically I'm using UIImagePickerController to grab an image from either the library or the camera, but the resulting image causes some... strange things to happen. Though it's laggy to pull the image up in a detail view controller containing a UIImageView, the real problem is that if I repetitively pull up the view controller and dismiss it, eventually parts of the image will have disappeared!!! More disturbingly, if I attempt to pull it up again after this has happened, the whole image will have turned black, and other UIViews throughout both my App AND the iPhone itself will either flicker wildly or have turned black!!!! For example, both the iPhone wallpaper and the initial "slide to unlock" panel turn black and flicker, respectively... It makes no difference whether the photo came from the library or the camera. The problem is entirely averted (no lag, no blackness) if I do something like this:
//UIImage* image = (UIImage*)[info objectForKey:UIImagePickerControllerOriginalImage];
UIImage* image = [[UIImage alloc] initWithData:
[NSData dataWithContentsOfURL:
[NSURL URLWithString:
#"http://wild-facts.com/wp-content/uploads/2010/07/Diving_emperor_penguin.jpg"]]];
Thus I can't imagine the problem having to do with anything other than the UIImagePickerController. Note that I'm still creating and dismissing it-- I'm just not grabbing the image out of it.
At first I thought the image was simply being overreleased, and the disappearing black chunks were parts of memory being overwritten. However, changing the image's retain count makes no difference. Then I thought, maybe the image is too large and somehow not getting properly released when I dismiss the UIImageView! Yet downloading a several MB image from the internet will not replicate the error. Then I thought, maybe the UIImagePickerController is disposing of the image, regardless of retain count! But copying the image failed as well. Furthermore, how could any of these things effect views that exist as deep as the iOS level?! I've researched, experimented, and Googled and no one has encountered this problem except for me... yet I'm not doing particularly strange! Is this an Apple issue? Did I forget something obvious? I've scanned up and down the documentation and guides to no avail, but perhaps I missed something.
None of this has worked:
Incrementing the retain count
Using [image copy]
None of this has replicated the problem with the downloaded image:
Decrementing the retain count
Downloading an image of size greater than 1 MB with large dimensions
I'm using the latest Verizon iPhone with iOS 4.2.8 (base SDK "overriden" to 4.3, whatever that means). 4.2.8 is the latest possible one for Verizon, though 4.3 is available for iPhones using AT&T.
Here's the code in glorious detail. I'm not yet checking for device compatibility, but it shouldn't matter concerning this. Perhaps I forgot some setting with the UIImagePickerController?
Quick Overview: I display an action sheet, then based on the user's input, display the image picker. I save the image as a transformable attribute on a Core Data object (delivery) using a custom transformer. I later hand the image to a detail view controller to display to the user.

If there's anything I can do to make this post more legible, please let me know. I'll add things that don't work/replicate the problem to the appropriate list. Thanks for taking the time to read this!
I just figured out the problem, had to do with excessive memory use. Thanks goes to this amazing post: https://stackoverflow.com/questions/1282830/uiimagepickercontroller-uiimage-memory-and-more Basically, before ever displaying the image, I divide each dimension by 4, resulting in a total 1/16th of the memory I was using before. Here's the method I used (as per the awesome post):
+ (UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize;
{
UIGraphicsBeginImageContext(newSize);
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
In the method call, I pass in CGSizeMake(image.size.width/4, image.size.height/4)
Hope this was helpful!
