How to open camera while I click the UIButton in iPhone? - iphone

I am trying to open the camera when I click the UIbutton in iPhone app. I want to store the captured image in a location that I specify.

You need to use something like this
- (IBAction)selectPhotos
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
imageView.image = image;
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
- (IBAction)saveImage:(id)sender {
if(imageView.image) {
[self showProgressIndicator:#"Saving"];
UIImageWriteToSavedPhotosAlbum(imageView.image, self, #selector(finishUIImageWriteToSavedPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
}
}

use [picker dismissViewControllerAnimated:YES completion:nil];
instead of [[picker parentViewController] dismissModalViewControllerAnimated:YES];

- (IBAction) useCamera: (id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker
animated:YES];
newMedia = YES;
}
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self.popoverController dismissPopoverAnimated:true];
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:YES];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
if (newMedia)
UIImageWriteToSavedPhotosAlbum(image, self,
#selector(image:finishedSavingWithError:contextInfo:),nil);
}
}
-(void)image:(UIImage *)image
finishedSavingWithError:(NSError *)error
contextInfo:(void *)contextInfo
{
if (error)
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle: #"Save failed"
message: #"Failed to save image"
delegate: self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissModalViewControllerAnimated:YES];
}

Iphone: Image picker is not working

I am implementing for imagePicker demo but it is not working.
When i click to pick image button ,nothing is happen. My code is as follow:
-(IBAction)pick:(id)sender
{
ipc=[[UIImagePickerController alloc]init];
ipc.delegate=self;
ipc.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
NSLog(#" %#",ipc.sourceType);
[ipc presentModalViewController:self animated:YES];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[[picker parentViewController]dismissModalViewControllerAnimated:YES];
[picker release];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
img.image=[info objectForKey:UIImagePickerControllerOriginalImage];
[[picker parentViewController]dismissModalViewControllerAnimated:YES];
[picker release];
}
please change ur code
[ipc presentModalViewController:self animated:YES];
to
[self presentModalViewController:ipc animated:YES];
The problem is you are trying to present the Modal view using:
[ipc presentModalViewController:self animated:YES];
Instead you should use:
[self presentModalViewController:ipc animated:YES];
How about this:
-(IBAction)pick:(id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker
animated:YES];
newMedia = YES;
}
-(void) imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self.popoverController dismissPopoverAnimated:YES];
NSString *mediaType = [info
objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
UIImage *image = [info
objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
if (newMedia)
UIImageWriteToSavedPhotosAlbum(image,
self,
#selector(image:finishedSavingWithError:contextInfo:),
nil);
}
else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie])
{
// Code here to support video if enabled
}
}

iPhone camera not showing up

I am having awkward problem in using the ios camera from a action sheet: When the user touches the "picture button" an action sheet shows up with two options (to use a photo from the photo library or to take a picture with the camera).
Whatever option I choose, nothing happens, but when I select the media type again, it works.
Bellow is my code:
- (IBAction)selectMediaType: (id)sender {
[appDelegate hideTabBar];
UIActionSheet *action = [[UIActionSheet alloc]
initWithTitle: nil
delegate:self
cancelButtonTitle:#"Fechar"
destructiveButtonTitle: nil
otherButtonTitles:#"Galeria", #"Tirar Foto", nil];
[action showFromTabBar: appDelegate.tabController.tabBar];
}
- (void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
NSArray *mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];
imagePicker.delegate = self;
imagePicker.hidesBottomBarWhenPushed = YES;
imagePicker.mediaTypes = mediaTypes;
imagePicker.allowsEditing = NO;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imagePicker animated:YES];
imagePicker.hidesBottomBarWhenPushed = YES;
} else if (buttonIndex == 1) {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
NSArray *mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];
imagePicker.delegate = self;
imagePicker.mediaTypes = mediaTypes;
imagePicker.allowsEditing = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
[self presentModalViewController:imagePicker animated:YES];
} else {
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#""
message:#"Your device does not support this feature!"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[alert show];
[alert release];
}
} else {
[appDelegate showTabBar];
}
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *image;
NSURL *mediaURL;
mediaURL = (NSURL *) [info valueForKey:UIImagePickerControllerMediaURL];
if (mediaURL == nil) {
image = (UIImage *) [info valueForKey:UIImagePickerControllerOriginalImage];
}
imageView.image = image;
[picker dismissModalViewControllerAnimated:YES];
[appDelegate showTabBar];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissModalViewControllerAnimated:YES];
[appDelegate showTabBar];
}
Could anyone help me with this?
Thanks.
I got it.
Basically it was a memory leak issue: I was switching views adding subviews in the super view (not in the current view) but I was not removing the old one from the super view, so I got a memory leak ;)

Capture Video as well as Images in iPhone

I am using ImagePickerController for Video Capturing. I need to save the capturing video as image also.
So I selected AVCaptureSession for capturing Images. I'm not able to run AVCaptureSession as well as ImagePickerController. So I need to give the ImagePickerController as input to the AVCaptureSession.
But I don't know how to do that. Please Help me.. and suggest me for the right way.
I found only these two. Hope its helps.

UIImagePickerController: Getting image capture from video
I was having same issue.. I did work on image and video and used below code for image capturing:
- (void) snapImage: (id) sendern
{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
ipc.delegate = self;
ipc.allowsImageEditing = YES;
[self presentModalViewController:ipc animated:YES];
}
And for video recording i used below code:
- (void) recordVideo: (id) sender
{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
ipc.delegate = self;
ipc.allowsEditing = YES;
ipc.videoQuality = UIImagePickerControllerQualityTypeMedium;
ipc.videoMaximumDuration = 30.0f; // 30 seconds
ipc.mediaTypes = [NSArray arrayWithObject:#"public.movie"];
// ipc.mediaTypes = [NSArray arrayWithObjects:#"public.movie", #"public.image", nil];
[self presentModalViewController:ipc animated:YES];
}
Hope will help you both code snippets.
- (IBAction) useCamera: (id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker
animated:YES];
newMedia = YES;
}
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self.popoverController dismissPopoverAnimated:true];
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:YES];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
if (newMedia)
UIImageWriteToSavedPhotosAlbum(image, self,
#selector(image:finishedSavingWithError:contextInfo:),nil);
}
}
-(void)image:(UIImage *)image
finishedSavingWithError:(NSError *)error
contextInfo:(void *)contextInfo
{
if (error)
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle: #"Save failed"
message: #"Failed to save image"
delegate: self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
The Apple docs and sample code related to AVFoundation has several mistakes. See iOS 4: Take photos with live preview using AVFoundation for code that actually captures images from a live preview.

Can't display UIImage from UIImagePickerController when using IBAction

I 'm new to xcode. I try to select an image from the UIImagePickerController and
then display this image pressing a button. But the simulator crashes.
In the .h I use
UIImage *dispimage; //in order to make a global image
-(IBAction) open;
-(IBAction) print;
In the .m I have
- (void)viewDidLoad {
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
dispimage = [info objectForKey:UIImagePickerControllerOriginalImage];
[self dismissModalViewControllerAnimated:YES];
}
-(IBAction) open{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
};
-(IBAction) print{
imageView.image=dispimage;
};
When the button "print" is pressed, the sdk crashes. :(
Any help would be appreciated
Thanks in advance

how to show video or movie file into UIImagePickerController?

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.
-(IBAction) selectImageSelected : (id)sender
{
actionSheet = [[UIActionSheet alloc] initWithTitle:#"Select Image"
delegate:self
cancelButtonTitle:#"Cancel"

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"];
