I am using UIimagepickercontroller to browse or take a photo and display it on a subview.
-(IBAction) getPhoto:(id) sender {
secondView1 = [[secondView alloc]
initWithNibName:#"secondView"
bundle:nil];
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if((UIButton *) sender == choosePhotoBtn) {
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
} else {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
[self presentModalViewController:picker animated:YES];
[self.view addSubview:secondView1.view];
}
This works fine for SourceTypeSavedPhotoAlbum, but if I use camera, the secondview1.view does not show. Instead it only shows the original view.
This is my delegate method:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
secondView1.imageView.image = [info
objectForKey:#"UIImagePickerControllerOriginalImage"];
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
[picker release];
}
Thank you for any help!
I finally found out that I should do:
secondView1 = [[secondView alloc]
initWithNibName:#"secondView"
bundle:nil];
self.view addSubview:secondView1.view];
in the delegate function.
(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
...
}
Otherwise, the addsubview could be called before the image picker finishes picking an image. Now understand better about how the code flows and the delegate functions.

Is there a way to decrease the memory when using the code below for the UIImagePickerController? The strange thing is that the memory is not coming above 26MB but it still shows the received memory warning. After taking a picture the app crashes. Memory warning only shows when choosing the camera, when choosing the library it's just fine.

I am writing an iOS app where, in a view there is a button. Clicking on that button gets an action sheet which has options to pick image from camera or gallery. After the image is picked, it should be passed on to another view by manually calling a segue. The image picker appears and the prepare for segue code is executed, but the segue doesnt appear. There are no errors and I have checked all identifiers etc. Here is the code:
-(IBAction)showButtonClicked:(id)sender {
UIActionSheet *photoActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Take Photo", #"Choose from Library", nil];
photoActionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
[photoActionSheet showInView:self.tabBarController.tabBar];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
switch (buttonIndex) {
case 0:
{
[self dismissModalViewControllerAnimated:YES];
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
break;
}
case 1:
{
[self dismissModalViewControllerAnimated:YES];
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
break;
}
default:
break;
}
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

photoDetails.imageView.image = self.buttonImage1;
}
}
- (void) imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
self.buttonImage1 = image;
//FostoPhotoDetailsViewController *photoDetails = [[FostoPhotoDetailsViewController alloc] init];
//photoDetails.imageView.image = image;
[self dismissModalViewControllerAnimated:NO];
NSLog(#"Test");
[self performSegueWithIdentifier:#"goToPhotoDetails" sender:self];
}
Sounds like you are executing a segue with style push without being inside a UINavigationController.
When you call performSegueWithIdentifier:sender: it first correctly calls prepareForSegue:sender: then it tries to retrieve the current navigation controller and push the destination controller doing something like
[self.navigationController pushViewController:destinationController animated:YES];
But since you are not inside a UINavigationController the property navigationController is set to nil, causing the above call to fail silently.
Either change the display style of your segue to something other than push (for instance modal) or embed you controller in a UINavigationController.
I have an app which has a toolbar at the bottom with one of the options as Upload. On clicking on it, a PopOverController occurs which displays the list of photos to choose from.
After choosing a photo, I want to display a view (inside the PopOverController itself)which contains the photo alongwith the button called as Upload. On choosing my photo, currently my PopOverController is not getting dismissed. I have used the following lines of code :
-(IBAction)photolibrarypressed:(id)sender{
NSLog(#"hi");
UIImagePickerController *picker= [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
self.popoverController = popover;
popoverController.delegate = self;
[popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
imageView = [[UIImageView alloc] initWithFrame:[window bounds]];
[window addSubview:imageView];
imageView.hidden = YES;
[window makeKeyAndVisible];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
imageView.image = image;
NSLog(#"hellow");
[self dismissModalViewControllerAnimated:YES];
// need to show the upload image button now
upload.hidden = NO;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissModalViewControllerAnimated:YES];
exit(0);
}
Can Someone help me to sort out the issue ??
Instead of calling
[self dismissModalViewControllerAnimated:YES];
call the same cancel method as int eh cancel method to handle dismissing it's modal view
[picker dismissModalViewControllerAnimated:YES]; // Dismisses modalView
I have an application that allows the user to select a photo from their camera roll, and display it in a UIImageView. But, after they tap on which image they would like to display, the camera roll's view does not disappear. So, I figured that I would need to simply call [sender resignFirstResponder];. But, this did not do the trick. I've been trying multiple things and doing searching around, but to no avail. I'm very new to Objective-C, so any help is much appreciated. Here is the code I'm working with:
(imgPicker is the UIImagePickerController.)
- (IBAction)grabImage(id)sender {
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
_popover = [[UIPopoverController alloc] initWithContentViewController:imgPicker];
[_popover presentPopoverFromRect:self.imageView.bounds inView:self.imageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
else {
[self presentModalViewController:imgPicker animated:YES];
}
[self.imgPicker resignFirstResponder];
}
And this may or may not be relevant to the issue:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo {
if (imageView.image == nil) {
imageView.image = img;
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
return;
}
if (imageView2.image == nil) {
imageView2.image = img;
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
return;
}
}
You need just this line to dismiss modal picker in your delegate method:
[picker dismissModalViewControllerAnimated:YES];
resignFirstResponder in this case is useless
Try
[self dismissModalViewControllerAnimated:YES];
As you want to dismiss only picker view and not parent view of picker
you just have to use:
[picker dismissModalViewControllerAnimated:YES];
and you are done.
I'm able to call the modal view controller for the image picker, pick the image, and crop it, but when I tap 'done' it doesn't do anything, it just hangs with the done button grayed out.
There are no errors, but the function is called.
- (void)viewDidLoad
{
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo {
userImage.image = img;
uploadButton.hidden = NO;
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
NSLog(#"called");
}
- (IBAction)getImage:(id)sender {
[self presentModalViewController:self.imgPicker animated:YES];
}
Replace
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
with:
[self dismissModalViewControllerAnimated:YES];
