Not calling UIImagePickerControl's methods by using AVCaptureSession in iPhone - iphone

I have used AVCaptureSession for capture photo in iPhone application. As well as I want to take an image from PhotosLibrary too.
I've implemented UIImagePickerController control and its all methods.
I can open library, But I can't get photo which I've selected. As well as not calling PickerView's methods. No response from those methods.
Is there any different way to implement UIImagePickerController control with AVCaptureSession for photos library?
Please tell me solution.
Or suggest me alternative solution instead of Overlay as I want both functionality with dynamic controls.
Thanks in advance.

For open photo library use this:
-(IBAction)pickphoto:(id)sender
{
[self startMediaBrowserFromViewController: self usingDelegate: self];
}
- (BOOL) startMediaBrowserFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate{
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
mediaUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie,kUTTypeImage, nil];
mediaUI.allowsEditing = YES;
mediaUI.delegate = delegate;
[controller presentModalViewController: mediaUI animated: YES];
return YES;
}
- (void) imagePickerController: (UIImagePickerController *) picker
didFinishPickingMediaWithInfo: (NSDictionary *) info
{
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
thumbnail = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
[self dismissModalViewControllerAnimated:YES];
}
And for capture a Image use this:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
[self presentViewController:imagePicker animated:YES completion:nil];

How to open full screen camera in Xcode

I am developing an app in which i need to keep open full screen camera open and also add a button on it(bottom right). I googled but couldn't find any healthy solution. Thanks in advance. Have a good day.
Edited
- (void) showCameraUI {
[self startCameraControllerFromViewController: self
usingDelegate: self];
}
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
NSLog(#"Start Camera Controller method...");
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
// Displays a control that allows the user to choose picture or
// movie capture, if both are available:
cameraUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeCamera];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}
P.S: I also added UINavigationControllerDelegate,UIImagePickerControllerDelegate as protocol in header file, but its not still opening camera and show me default view of project.
you can simply capture image Using camera like bellow, i am using this bellow method in my code:-
-(void)btnCemeraOpen
{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissModalViewControllerAnimated:YES];
yourImageView.image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
if(yourImageView==nil)
{
}
else
{
//DO logic
}
return;
}

iOS - How to store capture image and display it in your app

i am creating an application which capture an image form iphone camera and display it in the created application i read some articles in ios developer library and written this code in .m file
- (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;
// Displays a control that allows the user to choose picture or
// movie capture, if both are available:
cameraUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeCamera];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}
also created a button that is linked with this code,
It call this function but the control does not passes to the above function
- (IBAction) showCameraUI {
[self startCameraControllerFromViewController: self
usingDelegate: self];
}
And i also have no idea that this code will work or not
Do some one have any better idea.
Thanks,
Arun.
First assign delegate to it's source file
Then when you pressed your button implement this method open camera controller in your app
First of all create PopOverController for iPad because we cannot directly open ImagePicker Controller
EDIT: Added UIPopOverController
- (IBAction) showCameraUI {
BOOL hasCamera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
UIImagePickerController* picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = hasCamera ? UIImagePickerControllerSourceTypeCamera : UIImagePickerControllerSourceTypePhotoLibrary;
if (self.popoverController != nil) {
[self.popoverController dismissPopoverAnimated:YES];
self.popoverController=nil;
}
self.popoverController = [[UIPopoverController alloc] initWithContentViewController:picker];
CGRect popoverRect = [self.view convertRect:[yourBtn frame]
fromView:[yourBtn superview]];
popoverRect.size.width = MIN(popoverRect.size.width, 100) ;
popoverRect.origin.x = popoverRect.origin.x;
[self.popoverController
presentPopoverFromRect:popoverRect
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
And implement this delegate method for get the captured image
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissModalViewControllerAnimated:YES];
UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage];
UIImage *yourImageView = image;
if (popoverController != nil) {
[popoverController dismissPopoverAnimated:YES];
self.popoverController=nil;
}
}
Implement this method if user cancel the controller
- (void)imagePickerControllerDidCancel:(UIImagePickerController*)picker
{
[picker dismissModalViewControllerAnimated:YES];
if (popoverController != nil) {
[popoverController dismissPopoverAnimated:YES];
self.popoverController=nil;
}
}
- (void)pickerDone:(id)sender
{
if (popoverController != nil) {
[popoverController dismissPopoverAnimated:YES];
self.popoverController=nil;
}
}
You can use delegate: UIImagePickerControllerDelegate
Use bellow:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)mediaAndInfo
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

Trimming the video captured by the iphone camera programmatically?

I need to capture video for 5 minutes using iphone and then trim the captured video and save it in binary data format. If any body has done it ever, please help me to do so.
like that image http://www.askdavetaylor.com/3-blog-pics/apple-iphone-video-editing-4.png
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>) delegate {
NSLog(#"Camera Working");
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
cameraUI = [[UIImagePickerController alloc] init];
cameraUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
// Displays a control that allows the user to choose picture or
// movie capture, if both are available: video and image capturing
//cameraUI.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
cameraUI.videoMaximumDuration = 300; // 5x60 sec
cameraUI.allowsEditing = YES;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}

Set an image from camera roll to UIImageView

I've implemented a PickerController to have a user select an image, but I want the image the user selects to be displayed on the UIImageView I have.
I use the following to go to the camera roll:
- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];
[self presentModalViewController: picker animated: YES];
[self presentModalViewController: picker animated: YES];
}
Which brings up the camera roll in which a user can click on a photo. However, after the click, it returns to the main view, which is obvious... But how can I assign an action to the button, or image the user selects. Something like UIOKButton?
Something like:
if ([UIImagePickerController presentModalViewController:nil image:nil] == UIOKButton ) {
NSArray *images = [UIImagePickerController images];
for(UIImage* pickerImage in [UIImagePickerController images])
{
myUIImage.image setImage pickerImage;
//^in the view
}
I'm not exactly sure how to go about doing this.
All responses are appreciated.
Thanks!
- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];
[self presentModalViewController: picker animated: YES];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// Dismiss the picker
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
// Get the image from the result
UIImage* image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
myUIImage.image = image;
}
Use the delegate method: – imagePickerController:didFinishPickingMediaWithInfo:.

What function should I implement to return a selected picture from gallery? iphone sdk

What function should I implement to return a selected picture from gallery?
Use UIImagePickerController. In this example, I'm using the built-in image cropper as well.
- (void) showImage {
UIImagePickerController *imagePickerController = [[[UIImagePickerController alloc] init] autorelease];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
imagePickerController.delegate = self;
imagePickerController.allowsEditing = YES;
imagePickerController.mediaTypes = [NSArray arrayWithObject: (NSString *) kUTTypeImage];
[self presentModalViewController: imagePickerController animated: YES];
}
- (void) imagePickerController: (UIImagePickerController *) picker didFinishPickingMediaWithInfo: (NSDictionary *) info {
UIImage *image = [info objectForKey: UIImagePickerControllerEditedImage];
self.editedImage = image;
[self dismissModalViewControllerAnimated: YES];
}
- (void) imagePickerControllerDidCancel: (UIImagePickerController *) picker {
[self dismissModalViewControllerAnimated: YES];
}
This will allow the user to pick an image. If you don't want the cropping, set imagePickerController.allowsEditing = NO and use the key UIImagePickerControllerOriginalImage to get the resulting image back.
