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 ;)

I want to make an overlay on camera of my iphone app.I have followed this tutorial
But it teaches about capturing the image,I need to implement it on recording the video.
In the tutorial it is simply
- (void)takePicture
{
[picker takePicture];
}
But I am not able to implement it on recording the video,Please help me with an example if you can
Now without overlay I am using this coding for recording the video[I wish to implement it with the above tutorial]
-(void)ViewDidLoad

}
}

{
self.videoURL=[[info objectForKey:UIImagePickerControllerMediaURL] path];
self.videoData=[NSData dataWithContentsOfURL:[info objectForKey:UIImagePickerControllerMediaURL]];
[self dismissModalViewControllerAnimated:YES];
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType compare:(NSString*)kUTTypeMovie] == NSOrderedSame) {
NSURL *mediaUrl = [info objectForKey:UIImagePickerControllerMediaURL];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:mediaUrl];
moviePlayer.shouldAutoplay=NO;
UIImage *thumbnail = [moviePlayer thumbnailImageAtTime:0.0 timeOption:MPMovieTimeOptionNearestKeyFrame];

}
UIImagePickerController already has API for recording video. You can call
– startVideoCapture
– stopVideoCapture
to record video. Check the API

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;

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
- (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];
}
Hi I receive memory warning whenever I am using camera.
The error is like this:

How can i handle this?please help after taking picture i crop the image and save in application like this:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
iRolegameAppDelegate *appDelegate = (iRolegameAppDelegate *)[[UIApplication sharedApplication]delegate];
if(appDelegate.sound == 1)
{

}
[picker dismissModalViewControllerAnimated:YES];
imageView.image = image;
CGSize size = [imageView.image size];
CGRect cropRect = CGRectMake(0.0, 0.0, size.width, size.height);
NSValue *cropRectValue = [editingInfo objectForKey:#"UIImagePickerControllerCropRect"];
cropRect = [cropRectValue CGRectValue];
appDelegate.slectedimage = image;
imageView.hidden = YES;
if( [appDelegate.Name length] != 0 && max_att == 15)
{
btnNotDone.hidden = YES;
btnDone.enabled = YES;
}
//IMAGE SAVE IN DOCUMENTS//////
[UIImagePNGRepresentation(image) writeToFile:[self findUniqueSavePath] atomically:YES];
// Show the current contents of the documents folder
CFShow([[NSFileManager defaultManager] directoryContentsAtPath:[NSHomeDirectory() stringByAppendingString:#"/Documents"]]);
}
Please help me. I want to remove all warnings.
You're leaking the UIImagePickerController. Autorelease it on creation or release it after dismissModalViewControllerAnimated.
You may still get memory warnings, photos can be enormous, especially on the iPhone 4 and at a certain point you have two of them in memory: the UIImage and the autoreleased PNG.
P.S. you don't seem to be using size and cropRect so you could delete them.
Release your alert view. In general release any object you alloc. In case you have a retain property then assign a auto release object to it.
When you get a memory warning your view controller method - (void)didReceiveMemoryWarning is called. Here you will have to release any unwanted objects which you have cached. Typically that would be some images, views in stack etc.
Also check if you are having appropriate dealloc for objects in your modal view controller.
Are you implementing -imagePickerController:didFinishPickingMediaWithInfo:? The method you've implemented has been deprecated. You should use the other method even for images. What are you doing with the recorded videos?
On a side note, the following code –
#try
{
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
#catch (NSException * e)
{
UIAlertView *av = [[UIAlertView alloc] initWithTitle:#"ALERT"
message:#"Please try again"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"ok", nil];
[av show];
}
should be
if ( [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ) {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
} else {
UIAlertView *av = [[UIAlertView alloc] initWithTitle:#"ALERT"
message:#"Camera isn't available"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"ok", nil];
[av show];
[av release]
}
Now smarter thing would be to disable button 2 which would be
if ( ![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ) {
button2.enabled = N0;
}
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.

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.
