In iPhone Apps, I want to take pictures from Camera & save into Photo Gallery by programmatically. Is it possible in iPhone Simulator?
so please tell me any link or materials you have.
Thanks in advance
You would use uiimagepickercontroller for this purpose. First of all, import the MobileCoreServices.framework. Then pull up the camera:
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
NSArray *media = [UIImagePickerController
availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeCamera];
if ([media containsObject:(NSString*)kUTTypeImage] == YES) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
//picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
[picker setMediaTypes:[NSArray arrayWithObject:(NSString *)kUTTypeImage]];
picker.delegate = self;
[self presentModalViewController:picker animated:YES];
//[picker release];
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Unsupported!"
message:#"Camera does not support photo capturing."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Unavailable!"
message:#"This device does not have a camera."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
Then, save the photo by implementing the uiimagepickercontrollerdelegate and a save function:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSLog(#"Media Info: %#", info);
NSString *mediaType = [info valueForKey:UIImagePickerControllerMediaType];
if([mediaType isEqualToString:(NSString*)kUTTypeImage]) {
UIImage *photoTaken = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
//Save Photo to library only if it wasnt already saved i.e. its just been taken
if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
UIImageWriteToSavedPhotosAlbum(photoTaken, self, #selector(image:didFinishSavingWithError:contextInfo:), nil);
}
}
[picker dismissModalViewControllerAnimated:YES];
[picker release];
}
- (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];
[alert release];
}
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissModalViewControllerAnimated:YES];
}
More info on image:didFinishSaving.... can be found here

Also have a look at this post
https://stackoverflow.com/questions/1282830/uiimagepickercontroller-uiimage-memory-and-more
it is not possible in simulator.You have to use the device.
I do hope you realize that the simulator does not have a camera..... So I guess thats not possible. You can definitely use a device.... You can make use of UIImagePickerController for capturing images.
There are 3 prerequesites needed to take a picture programmatically:
The device needs to have a camera check by
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
Camera controls need to be hidden (picker is a UIImagePickerController)
picker.showsCameraControls = NO;
use the takePicture from UIImagePickerController
[picker takePicture];
Side note because it did bug me for a few minutes, the takePicture method also dismisses the view.

In my iPhone app,a user can record the video.I want to set the maximum allowed time of recording is to 30seconds.How to do that,any ideas ?
using this code
-(BOOL)startCameraControllerFromViewController:(UIViewController*)controller
usingDelegate:(id )delegate {
if (([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil)) {
return NO;
}
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
cameraUI.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:NO];
if (CFStringCompare ((__bridge_retained CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) {
NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
NSLog(#"movie path %#",moviePath);
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath)) {
UISaveVideoAtPathToSavedPhotosAlbum(moviePath, self,
#selector(video:didFinishSavingWithError:contextInfo:), nil);
}
}
}
-(void)video:(NSString*)videoPath didFinishSavingWithError:(NSError*)error contextInfo: (void*)contextInfo {
if (error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Video Saving Failed"
delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Video Saved" message:#"Saved To Photo Album"
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
}
}
You need to set the videoMaxiumDuration property on UIImagePickerController after configuring it for video recording.
The value is an NSTimeInterval which is specified in seconds, so you'll want to set it to 300 seconds if you want 5 mins of video.
My app crashes when I try to take more than one picture using UIMagePickerController. So, first time I take a picture everything is fine, second time around the app crashes without any error messages. I do get this the first time around:
2013-01-11 16:36:24.178 DoodleStash[26778:907] Received memory warning.
Here's the code I am using to take a photo:
- (IBAction)takePhoto:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
[self presentViewController:imagePicker animated:YES completion:nil];
self.isNewDoodle = TRUE;
}}
And here's what I use to save the photo
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
[self dismissViewControllerAnimated:YES completion:nil];
if ([mediaType isEqualToString:(NSString *) kUTTypeImage]) {
self.doodleImage = [info objectForKey:UIImagePickerControllerOriginalImage];
// Check to make sure the image is new
if (self.isNewDoodle == TRUE) {
UIImageWriteToSavedPhotosAlbum(self.doodleImage, self, #selector(image:finishedSavingWithError:contextInfo:), nil);
}
[self performSegueWithIdentifier:#"confirmUploadSegue" sender:self];
}}
Really appreciate any help on this. Complete code is here https://gist.github.com/4515007
This is not a crash, but rather a memory warning (the app is killed by the system in low memory condition). It is hard to tell why your app is using too much memory without seeing all the code. You should use profiler to investigate.
In the code given, you could decrease memory usage by only performing the segue after writing the image (in image:finishedSavingWithError:contextInfo:) and zeroing doodleImage after it's no longer needed (possibly in prepareForSegue:sender:). The latter is particulatrly important if you reuse TakePhoto controller (because the second time you use it, you are still holding a reference to previously taken image, effectively doubling memory uage).
First of all for camera open try below lines:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
[self presentViewController:imagePicker animated:YES completion:nil];
Try this in for save image after camera click:
**UPDATED ANSWER**
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
if (self.isNewDoodle == TRUE)
{
UIImageWriteToSavedPhotosAlbum(image, self, #selector(image:finishedSavingWithError:contextInfo:), nil);}
[self performSegueWithIdentifier:#"confirmUploadSegue" sender:self];
}
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)image:(NSString*)videoPath didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo
{
if (error)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Photo Saving Failed" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles: nil, nil];
[alert show];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Photo Saved" message:#"Saved To Photo Album" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles: nil];
[alert show];
}
}
Try now this & check.
I am getting an error / crash on iPad only when using the following code, iPhone works fine.
It is basically when trying to load the gallery to pick an image.
The debug error is;

Could anyone be so kind as to help with the code above ? I am guessing an if/else statement but have not the first idea of what it would be and where to place it.
Thanks in advance,

EDIT - Ok I now have it working the load from gallery now loads 'Photos' in a small window, where I can select, however there is no 'Select' or 'Choose' button, if I click the photo, there is no tick, to say it is selected, however it does select it, but to dismiss I click outside the window... So it works, but I am guessing I have missed something out, here is the code;

{
[popoverController release];

}

popoverController = popover;

The error is very clear:
On iPad, UIImagePickerController must be presented via UIPopoverController'
You need to put the image picker in a popover controller when run on the iPad. This is true when the sourceType is for the photo library. The camera based image picker can be shown as a full screen modal view controller.
This isn't an issue on the iPhone because the iPhone doesn't support the UIPopoverController.
The sample app PrintPhoto demonstrates how to show the image picker in a popover. Specifically, see PrintPhotoViewController.m.
Do something like this:
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
//present as a pop over vc
} else {
//present as a modal vc
}
To present a popover you might use this method
- (void)presentPopoverFromRect:(CGRect)rect inView:(UIView *)view permittedArrowDirections:(UIPopoverArrowDirection)arrowDirections animated:(BOOL)animated
You can read the documentation at this link link
I am currently developing an iPhone app that makes use of a UIImagePickerController with a custom overlay to take photos.
Unfortunately I do not have direct access to an iPhone 4S but several testers have reported that the camera picker is drawing a green border around faces exactly like this: http://cdn.iphonehacks.com/wp-content/uploads/2012/03/camera_faces.jpg
Due to the nature of this app this is not desirable.
A thorough search of the UIImagePickerController docs didn't turn up anything and similarly everything I could find on here relating to face detection was providing instructions in how to use a CIDetector or similar.
How can I disable face detection in my UIImagePickerController?
Here is my initialisation code for the UIImagePickerController:
UIImagePickerController *cameraPicker = [[UIImagePickerController alloc] init];
[cameraPicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[cameraPicker setCameraDevice:UIImagePickerControllerCameraDeviceRear];
if ([UIImagePickerController isFlashAvailableForCameraDevice:cameraPicker.cameraDevice]){
[cameraPicker setCameraFlashMode:UIImagePickerControllerCameraFlashModeOn];
}
[cameraPicker setShowsCameraControls:NO];
[cameraPicker setCameraOverlayView:cameraOverlayView];
cameraPicker.delegate = self;
[self presentModalViewController:cameraPicker animated:YES];
Try This -->
Lets Say We have one UIViewController named as - RecordVideoViewController

Implement This code it, i hope this will help you .
Check out this post. There are some hints here, but still can't find much info outside of Apple's docs on this API.
Proper usage of CIDetectorTracking
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
UINavigationController *HomeNav = [[UINavigationController alloc] initWithRootViewController:[[HomeController alloc] init]];
[HomeNav.navigationBar setTintColor:[UIColor clearColor]];
CustomTabBar *tabBar = [[CustomTabBar alloc] init];
tabBar.buttonImages = [NSArray arrayWithObjects:#"t1.png" , nil];
tabBar.hightLightButtonImages = [NSArray arrayWithObjects:#"th1.png", nil];
tabBar.viewControllers = [NSArray arrayWithObjects:HomeNav , nil];
self.tabBarController = tabBar;
[tabBar release];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
in HomeController view, there is one button
if tap the button I call `AViewController.
-(IBAction)tapButtonA:(id)sender;
{
[self.navigationController pushViewController:AViewController animated:YES];
}
there is also a button on the view of AViewController.
if I tap the button, I call UIImagePickercontroller
-(IBAction)tapButtonB:(id)sender;
{
UIImagePickerController *picker=[[UIImagePickerController alloc]init];
picker.delegate=self;
picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
picker.allowsImageEditing = YES;
[self presentModalViewController: picker animated:NO];
}
If I tap the cancel button of the UIImagePickerController
-(void)imagePickerControllerDidCancel:(UIImagePickerController*)picker{
[self.presentingViewController dismissModalViewControllerAnimated:YES];
}
the UIImagePicker will dismiss, but after 1,2 seconds the app crashes and displays
Welcome any comment
Following code is solve your problem,

This code may helping to solveing your problem
I think you want:
-(void) imagePickerControllerDidCancel:(UIImagePickerController*)picker {
[picker.presentingViewController dismissModalViewControllerAnimated:YES];
}
try this
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissModalViewControllerAnimated:YES];
}
