Cancel button not working in UIImagePickerView - ios

Question

I am use UIImagePickerView in my code in which three buttons are there. One to take photo, second to choose photo and third to cancel. The code as below:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Select the operation to proceed?"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Take Photo", #"Select Photo", nil];
[actionSheet showInView:self.view];
When I click on the Cancel button it does not work.
I am using UIImagePickerViewDelegate method as below.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
#try {
//set selected image in imageview by imagepickerview
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
imgProfilePic.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:nil];
}
#catch (NSException *exception) {
NSLog(#"%#",exception.description);
}
}
//- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
//{
// NSLog(#"####");
// [picker dismissViewControllerAnimated:YES completion:NULL];
//}
Please check my code for UIImagePickerView and provide me guidance for correct code.
#pragma mark - Actionssheet delegate method for Image
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
#try {
if(buttonIndex != 3)
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
if(buttonIndex == 0)
{
NSLog(#"Choose Photo from Camera");
//simulator has no camera so app will crash, below call just provide the alert that device has no camera.
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Device has no camera"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[myAlertView show];
}
else
{
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
}
if(buttonIndex == 1)
{
NSLog(#"Choose Photo from Gallary");
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
// if (buttonIndex == 3)
// {
// NSLog(#"###");
// }
//
// else
// {
// NSLog(#"Cancel the tab");
// [picker dismissViewControllerAnimated:YES completion:NULL];
//
// }
[self presentViewController:picker animated:YES completion:nil];
}
}
#catch (NSException *exception) {
NSLog(#"%#",exception.description);
}
}

I think you are new for the stackOverflow and iOS application Development. That UIActionsheet and UIImagePickerController both are different things. So if you are create a actiohsheet like:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Select the operation to proceed?"delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil otherButtonTitles:#"Take Photo", #"Select Photo", nil];
[actionSheet showInView:self.view];
Now you can called its button method like following:
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex==0)
{
// take photo selected
}
else if (buttonIndex==1)
{
// select photo selected
}
else
{
// cancel button selected
}
}
You can also use UIAlertController that is the replacement of UIAlert and UIActionSheet from iOS8 so you can use like following:
UIAlertController* AlertSheet = [UIAlertController alertControllerWithTitle:#"New ActionSheet" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:#"Action" style:UIAlertActionStyleDefault //
handler:^(UIAlertAction * action) {
NSLog(#"Action");
}];
[AlertSheet addAction:defaultAction];
UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
}];
[AlertSheet addAction:cancleAction];
[self presentViewController:AlertSheet animated:YES completion:nil];

You can try this code its work for me
UIAlertController* alert = [UIAlertController
alertControllerWithTitle:nil // Must be "nil", otherwise a blank title area will appear above our two buttons
message:nil
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* button0 = [UIAlertAction
actionWithTitle:#"Cancel"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action)
{
// UIAlertController will automatically dismiss the view
}];
UIAlertAction* button1 = [UIAlertAction
actionWithTitle:#"Take photo"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
// The user tapped on "Take a photo"
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL]; }];
UIAlertAction* button2 = [UIAlertAction
actionWithTitle:#"Choose Existing"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
// The user tapped on "Choose existing"
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}];
[alert addAction:button0];
[alert addAction:button1];
[alert addAction:button2];
[self presentViewController:alert animated:YES completion:nil];

UIActionSheet is deprecated since iSO 8. You should use UIAlertController
UIAlertController* alert = [UIAlertController
alertControllerWithTitle:nil // Must be "nil", otherwise a blank title area will appear above our two buttons
message:nil
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* button0 = [UIAlertAction
actionWithTitle:#"Cancel"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action)
{
// UIAlertController will automatically dismiss the view
}];
UIAlertAction* button1 = [UIAlertAction
actionWithTitle:#"Take photo"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
// The user tapped on "Take a photo"
UIImagePickerController *imagePickerController= [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:YES completion:^{}];
}];
UIAlertAction* button2 = [UIAlertAction
actionWithTitle:#"Select Photo"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
// The user tapped on "Select Photo"
UIImagePickerController *imagePickerController= [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:YES completion:^{}];
}];
[alert addAction:button0];
[alert addAction:button1];
[alert addAction:button2];
[self presentViewController:alert animated:YES completion:nil];
