I have a tableView, and I want to take a picture when clicking in one of the cells and upload it to a certain server.
I have managed to do this so far:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//do actions
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
// Set the image picker source to the camera:
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
// Hide the camera controls:
picker.showsCameraControls = YES;
picker.navigationBarHidden = NO;
// Make the view full screen:
picker.wantsFullScreenLayout = YES;
//picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform, CAMERA_TRANSFORM_X, CAMERA_TRANSFORM_Y);
// Now insert our overlay view (it has to be here cuz it's a modal view):
//picker.cameraOverlayView = overlayView;
matches *aMatch = [appDelegate.matches objectAtIndex:indexPath.row];
NSLog(#"%#", [NSString stringWithFormat:#"%d", aMatch.match_id]);
// Show the picker:
[self presentModalViewController:picker animated:YES];
[picker release];
}
It starts the camera and takes the picture, but I would like to get an "Upload" button when clicking in "use", can you help me? is it posible? (like the facebook app)
By the way, whe I click in use it comes back to the table view, but where is the image? is it saved in picker?
you get your image in the delegate method of image picker controller
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo
{
//write your code here to save image in ur UIImage object for e.g:-
UIImage *myImage = img;
// add upload button from here or else set it hidden property to false if u have previously created upload button and had set ti to hidden
}
Maybe I didn't explain myself very good, but here is an example of what I was trying to do ( customize the look of the camera by adding an upload button): http://developer.apple.com/library/ios/#samplecode/PhotoPicker/Introduction/Intro.html%23//apple_ref/doc/uid/DTS40010196-Intro-DontLinkElementID_2
Thank you.

When i open Camera in my app it works fine, but when i navigate in my app and comes back to camera view and again try to open my camera in iPad, app crashes and gives me "Received memory warning". app working fine in iPhone and this issues is only coming in iPad.
My project was without ARC so i converted my project into ARC in the hope to get good results but still my app crashes on camera after little navigation.
can anybody tell me how to decrease memory space with iPad camera so that my apps stop receiving memory warning.
this is my code for camera
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
imagePicker=[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = NO;
//imagePicker.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:imagePicker animated:YES completion:nil];
}
This is where I get my Image
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[Array removeAllObjects];
[picker dismissViewControllerAnimated:YES completion:nil];
image = [info objectForKey:UIImagePickerControllerOriginalImage];
[array addObject:image];
image=nil;
}
and i have also try to use popOverview for camera but it also didn't work.
In my viewController where I'm calling UIImagePickerController I have used 5 animations, before i was calling animation in viewWillAppear, and app was crashing so i changed Animation calling to ViewDidLoad and camera starting working but only until I navigate to my last view and comes back to open camera again.
I am getting same problem so i do like this.
Set UIImagePickerController as static like this.
static UIImagePickerController *imagePicker;
When you get image in this deleget.
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
#autoreleasepool {// to release memory
// Probelm is you image size.
// When you get this image it is vary large.
// And i hope you are creating multiple copy's of this image.
// when you get image in
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
// In last set image as nil
image = nil;
}
}
Hope this will solve you problem.. :-)
Try to run your app without animation and then try, if it works then you need to improve your animations memory allocation, as animation needs a lot of memory.
Please try below code.try UIImagePickerController with in popover
if([UIImagePickerContrller isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *controller = [[UIImagePickerController alloc] init];
controller.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
controller.allowsEditing = YES;
controller.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
controller.delegate = self;
UIPopoverController *popController = [[UIPopoverController alloc] initWithContentViewController:controller];
popController.popoverContentSize = CGSizeMake(350.0f, 500);
[popController presentPopoverFromRect: self.button.frame inView:self.button.superview
permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES]
}
I'm relatively new to X Code
and
I m working on photo collage App , when i pick image from one picker then image picker is working properly but i want to pick different images from different imagepicker then image picker is not working properly
Anyone help me solve my problem. Here is my code
`

{
imagepicker=[[UIImagePickerController alloc]init];
imagepicker.delegate=self;
imagepicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imagepicker animated:YES];
button1.tag=100;
}

}
`
//Take two imageView in your .h file
UIImageView *imgViewForFirstPicker;
UIImageView *imgViewForSecondPicker;
// Alloc these images in view did load
imgViewForFirstPicker = [[UIImaeView allo] initWithFrame:(give your rect)];
// Similarly for second imageView and add to both in self.view

{
UIImagePickerController *imagepicker=[[UIImagePickerController alloc]init];
imagepicker.delegate=self;
imagepicker.tag=100;

}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage: (UIImage*)image editingInfo:(NSDictionary *)editingInfo
{
[picker dismissModalViewControllerAnimated:YES];
if(picker.tag == 100)
imgViewForFirstPicker.image=image;
else
imgViewForSecondPicker.image=image;
}
try this one hope it will help you
UIImagePickerController creates a pretty heavy object, So I don't think it is advisable to create multiple instances of it. May be this is what is causing the problem if you are doing the same.. It would be nice if you could share your code as well so we can have more insights into your problem
It is advisable to just use on image picker. From the code you provided you are trying to create two different imagepicker delegate methods, but in reality only one of them will be called both times.
You should create on instance of imagePicker and change its tag depending on which image you needed changed and then in the -didFinishPickingImage check if (picker.tag == SOME_TAG) then set appropriately.
I want to use UIImagePickerController takePicture method.
the problem his that the UIImagePickerController is not show in the screen and the user cannot press the Use button to accept the img.
Is there is any way to skip this screen and go straight to :
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
for saving the image?
The only way that I have found to do this is to use a custom overlay for UIImagePickerController. You can do that with code akin to that below:
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
//create custom overlay and allocate it as "customOverlayView"
picker.cameraOverlayView = customOverlayView;
//do any other setup desired for picker
[self presentViewController:picker animated:YES completion:nil];
[picker release];
Now once the takePicture method is called, the delegate didFinishPickingMediaWithInfo: will be called immediately like you desire.
I am using UIImagePickerController in an iOS app to save an image in context using UIGraphicsBeginImageContext/UIGraphicsBeginImageContextWithOptions.
I recently noticed that I picture I had saved and then displayed at a later date was highly pixelated; when I went back with the same code and imported the photo again, I got a great image. After playing with this for a while on my device, I figured out that the quality of the image saved depends on WHEN I pressed the 'Choose' button on the 'Move and Scale' screen.
If the image is a larger image and still loading when I press the button, the image is pixelated... if I wait until the image loads, it is fine. My question is, is there any way I can control when the user presses the 'Choose' button - is there any way to force them to wait until after the image is fully loaded? Or is there another way that would be better to approach this issue?
- (void)choosePhoto {
//NSLog(#"%s", __FUNCTION__);
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
//NSLog(#"%s", __FUNCTION__);
[self dismissModalViewControllerAnimated:YES];
UIImage *pickedImage = (UIImage*)[info objectForKey:#"UIImagePickerControllerEditedImage"];
[self setPersonImage:pickedImage];
}
- (void) setPersonImage:(UIImage *)pickedImage {
//NSLog(#"%s", __FUNCTION__);
NSManagedObjectContext *context = [[UIApplication sharedDelegate] managedObjectContext];
PersonImage *oldImage = person.image;
if (oldImage != nil) {
[context deleteObject:(NSManagedObject*)oldImage];
}
if (pickedImage != nil) {
// Create an image object for the new image.
PersonImage *newImageObject = [NSEntityDescription insertNewObjectForEntityForName:#"PersonImage" inManagedObjectContext:context];
[newImageObject setImage:pickedImage];
[person setImage:newImageObject];
}
else {
[person setImage:nil];
}
NSError *error;
if (![context save:&error]) {
exit(-1); // Fail
}
}
I suggest you implement your own Crop&Resize view controller.
set imagePicker.allowsEditing = NO.
create your view controller in - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info and pass selected image to your view controller.
push your view controller to image picker: [picker pushViewController:yourVC animated:YES]
The image captured by the iPhone 4 camera is ~5 MB in size and it takes a while to display/render it. One option is to compress the image using UIImageJPEGRepresentation().
If you do not want to compress the image, you can use UIWebView to display the images. The UIWebViewDelegate has a method - (void)webViewDidFinishLoad:(UIWebView *)webView, that hits after the rendering has been completed. You can enable the choose button in this method (which is disabled initially).
I'm new to iPhone and I'm using this code to select an image from the iPhone library and show it in imageView. The library is showing images, but when I'm selecting the image, it doesn't appear in the image view..
- (void)viewDidLoad {
[super viewDidLoad];
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
imageView.image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
}
Please can you tell me what's the problem with the code?
Try with:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *pickedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = pickedImage;
[self dismissModalViewControllerAnimated:YES];
}
UIImagePickerControllerOriginalImage is a string constant that could be different from #"UIImagePickerControllerOriginalImage" string.
Then, it's safe and more clear to former set the image view, and latter to dismiss the modal view controller.
Pay attention that you should invoke dismissModalViewControllerAnimated: on self because you are dismissing the modal view controller "owned" by self.
Bye!
I fixed my issue of "grey box appearing instead of an image in UIImageView".
I forgot to make the Background color of the UIIMageView to be CLEAR COLOR. THe problem was solved by setting background color to clearColor.
Was using XIB and you should also check if anything is laid out wrong in Interface builder in case you are using interface builder to create UI.
