Issue with dismissModalViewController - iphone

I've got a problem when i dismiss a modal view:
I've got a tabBar with five tabs.
I'm on the fourth tab and i display a modal view.
When i dismiss it. I go on the first tab but i would like to stay on the fourth.
To show the modal I call this method, in the parent controller:
[self presentModalViewController:controller animated:YES];
To hide the modal I call this method, in the parent controller:
[self dismissModalViewControllerAnimated:YES];
I already try to call self.tabBarController/self.navigationController methods instead of self method but it's the same issue.
Someone has an idea?
EDIT:
I call the methods in the fourth tab's controller.
This is the context:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.allowsEditing = NO;
imgPicker.delegate = self;
switch (buttonIndex) {
case 0: {
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:kMobiglissFromPicker];
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imgPicker animated:YES];
break;
}
case 1: {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:kMobiglissFromPicker];
imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:imgPicker animated:YES];
}
break;
}
}
}
- (void)imagePickerController:(UIImagePickerController *)imgPicker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *origin = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
UIImage *photo = [origin thumbnailImage:280
transparentBorder:0.0
cornerRadius:0.0
interpolationQuality:kCGInterpolationHigh];
[icon replaceImageWithImage:photo];
[serverProxy updateProfileAvatar:photo];
[self dismissModalViewControllerAnimated:YES];
imgPicker.delegate = nil;
}
- (IBAction)editAvatar:(id)sender {
NSString *camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ? [WPLanguage get:#"SignupPhotosheetCamera"] : nil;
UIActionSheet *photoSheet = [[UIActionSheet alloc] initWithTitle:[WPLanguage get:#"SignupPhotosheetTitle"]
delegate:self
cancelButtonTitle:[WPLanguage get:#"CANCEL"]
destructiveButtonTitle:nil
otherButtonTitles:[WPLanguage get:#"SignupPhotosheetGallery"], camera, nil];
[photoSheet showInView:self.view];
}

Just a guess (you need to add more details): Does your viewController, which implements the UITabBarDelegate, set the selected item on viewWillAppear: (or one of the other methods called?

Viewcontroller not appearing since iOS7

Edit - I solved this myself - see the notes at the bottom
When using iOS7 on Xcode 5, I am using an option to take an image from a camera, or from the photo library, once the image is chosen (or a new picture taken) the view should flip over to the next screen.
This does not happen on the iPhone running iOS7, it works fine on the iPad, but the method is slightly different, but it does appear to be iPhone only problem on iOS7.
here is the code used, for example, on the choose image from library function;
-(void) choosePic {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]) {
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
cameraUI.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeSavedPhotosAlbum];
cameraUI.allowsEditing = NO;
cameraUI.delegate = self;
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
_popover = [[UIPopoverController alloc] initWithContentViewController:cameraUI];
[_popover presentPopoverFromRect:btnLibrary.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
else
[self presentModalViewController: cameraUI animated: YES];
}
}
Also, the code once picker is finished;
- (void) imagePickerController: (UIImagePickerController *) picker didFinishPickingMediaWithInfo: (NSDictionary *) info {
//Disable buttons
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[self disableButtons];
//Get image
self.originalImage = (UIImage *) [info objectForKey: UIImagePickerControllerOriginalImage];
//Dismiss
if(_popover)
{
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
[_popover dismissPopoverAnimated:YES];
_popover = nil;
}
}
else
[picker dismissModalViewControllerAnimated: YES];
//Next
[self performSelector: #selector(nextScreen) withObject:nil afterDelay:0.5];
}
I fixed this by switching out;
[picker dismissModalViewControllerAnimated: YES];
With
[picker dismissViewControllerAnimated:NO completion:nil];
First you need to make sure that logic reaches the correct place it's intended to, try setting a breakpoint or NSLog before the iPhone's specific line, try this (You also missed curled braces, added them here) :
-(void) choosePic {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]) {
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
cameraUI.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeSavedPhotosAlbum];
cameraUI.allowsEditing = NO;
cameraUI.delegate = self;
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
_popover = [[UIPopoverController alloc] initWithContentViewController:cameraUI];
[_popover presentPopoverFromRect:btnLibrary.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}else{
NSLog(#"Checkpoint !");
[self presentModalViewController: cameraUI animated: YES];
}
} }

IOS UIImagePicker in a UIView subview

I am trying to display a UIImagePicker from a programatically generated UIView that's added as a subview of the original view controller. The image picker comes up and so does the camera but the functionality breaks and nothing navigates properly. How do I properly load an image picker from a UIView and not a UIControlView?
code that breaks:
- (void)captureImage:(id)sender
{
[[[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:#"Close"
destructiveButtonTitle:nil
otherButtonTitles:#"Take photo", #"Camera Roll", nil]
showInView:self];
}
//UIImagePicker specific methods
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex)
{
case 0:
[self takePhoto];
break;
case 1:
[self fromCameraRoll];
break;
}
}
-(void)takePhoto
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES)
{
// Create image picker controller
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
// Set source to the camera
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
// Delegate is self
imagePicker.delegate = self;
// Show image picker
[self addSubview:imagePicker.view];
}
}
-(void)fromCameraRoll
{
UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self addSubview:imgPicker.view];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Access the uncropped image from info dictionary
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
//do something with the image
//add code to pick images here and store them in the preview
[picker dismissModalViewControllerAnimated:NO];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissModalViewControllerAnimated:NO];
}
UIImagePickerController is view controller class, you better present your image picker to your parent view controller by a delegate call or something like with an overlay subview to achieve your goal.
UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
CustomOverlayView *overlayview = [[CustomOverlayView alloc] init];
imgPicker.cameraOverlayView = overlayview;
[self presentModelViewController:imgPicker animated:YES];
add another delegate in your overlay class to dismiss your camera picker controller view
[imgPicker dismissModelViewControllerAnimated:YES];

Selecting image on iPad

I'm trying to write code to select an image from the photo library on an iPad. The code that I'm using is below (taken from Apple's website), but it keeps giving me an error saying that On iPad, UIImagePickerController must be presented via UIPopoverController. I've tried changing this line: UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init]; to use a UIPopoverController, but obviously I'm doing something wrong because its not working.
- (BOOL) selectImage: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
// Displays saved pictures and movies, if both are available, from the
// Camera Roll album.
mediaUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeSavedPhotosAlbum];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
mediaUI.allowsEditing = NO;
mediaUI.delegate = delegate;
[controller presentModalViewController: mediaUI animated: YES];
return YES; }
The Apple Developer page also says: "On iPad, you can alternatively present the browser interface using a popover as described in initWithContentViewController: and “Presenting and Dismissing the Popover” in UIPopoverController Class Reference." I've read it but I still can't get it to work. Any help would be appreciated.
Something like this should work:
// create an image picker controller
UIImagePickerController *imagePickerController = [[[UIImagePickerController alloc] init] autorelease];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
imagePickerController.delegate = self;
// present it in a popover
self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:imagePickerController] autorelease];
self.popoverController.delegate = self;
// I was presenting the popover from a button, but you would set the rect to whatever is appropriate for your app
[self.popoverController presentPopoverFromRect:((UIButton *)sender).bounds inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Declare an ivar such as:
UIPopoverController *imagePopover;
Then:
imagePopover = [[UIPopoverController alloc] initWithContentViewController:mediaUI];
[imagePopover setDelegate:self];
[imagePopover presentPopoverFromRect:someRect
inView:someView
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
in place of
[controller presentModal...];
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[popover presentPopoverFromRect:CGRectMake(0.0, 0.0, 400.0, 400.0)
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];

I went through a lot of pain coming up with a solution which works on both iPad and iPhone, this is the final code which some of it comes from comments of other people:
the code has some bugs but it's a very good place to start :)
it covers permissions needed as well as how to manage viewcontrollers popoing up on ipad.
requires following imports :
#import <AVFoundation/AVFoundation.h>
#import <AssetsLibrary/AssetsLibrary.h>
and add this delegates :
UIActionSheetDelegate, UIImagePickerControllerDelegate
definitions :
__weak IBOutlet UIButton *attachButton;
UIImage *image;
button's action :
- (IBAction)doAttach:(id)sender {
UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:#"Select image from" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"From library",#"From camera", nil] ;
[action showInView:self.view];

how to take picture from camera using iphone app

I have implemented picture taking while pressing UI Button butwhen ever i pressed the button got app crashed.
Here is the source code.
.h file
#interface Camera : UIViewController
<UIImagePickerControllerDelegate>
{
UIImagePickerController *mPicture;
}
#property (nonatomic, retain) UIImagePickerController *mPicture;
.m file
#implementaion Camera
#synthesize mPicture;
-(void)pictureButtonPushed
{
UIImagePickerControllerSourceType mType = UIImagePickerControllerSourceTypeCamera;
if ([UIImagePickerController isSourceTypeAvailable:mType])
{
mPicture.sourceType = mType;
[self presentModalViewController:mPicture animated:YES];
}
}
Thanks in advance

Use this image object where ever you want to use.

I want to add transition effect with every image of the slide show which i created so how i will add?

Here is few code related to my slide show,What i want is to add transition effect on each img.Img will be picked from library and add the transition effect on that img so when we play the slide the image with specific transition should be played means when 1 transition will disapear with their trans. effect another will appear with their transition effect..

UIView has a class method by which you can transition from one view to another with a transition. Use it like this:
[UIView transitionFromView:currentView toView:newView duration:1.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil];
For more information refer to Apple's UIView documentation.
