Chosen Image Is Not Showing - ios

Question

I have built an camera and library app where I am choosing image from my library and showing it to an imageView. But the problem that is happening is after choosing the image is not showing in imageView.
Here is my code.
#interface ViewController ()
{
BOOL isImageselected;
UIImageView *myImage;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Device has no camera"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[myAlertView show];
}
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)addPhotoButton:(id)sender {
[UIView animateWithDuration:0.3 animations:^{
// animation here
self.pickerView.frame = CGRectMake(0.0, 443.0, 320.0, 125.0);
}];
}
- (IBAction)cameraButton:(id)sender {
[UIView animateWithDuration:0.3 animations:^{
// animation here
self.pickerView.frame = CGRectMake(0.0, 568.0, 320.0, 125.0);
}];
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)uploadImageButton:(id)sender {
[UIView animateWithDuration:0.3 animations:^{
// animation here
self.pickerView.frame = CGRectMake(0.0, 568.0, 320.0, 125.0);
}];
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
myImage.image = chosenImage;
isImageselected = YES;
if (isImageselected == YES) {
myImage = [[UIImageView alloc]initWithFrame:CGRectMake(8.0, 8.0, 95.0, 95.0)];
self.addPhotoButton.frame = CGRectMake(106.0, 8.0, 95.0, 95.0);
}
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
#end
I think the problem is happening where I am creating the imageView dynamically but I am not getting the point what is wrong.

Answer 1

Problem is that you assigning image to UIImageView object myImage before creating myImage.
Try to place the line
myImage.image = chosenImage;
After this line:
myImage = [[UIImageView alloc]initWithFrame:CGRectMake(8.0, 8.0, 95.0, 95.0)];

Answer 2

This because after adding the selected photo to myImage you are re allocating myImage, this create new object of myImage. Try this
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
isImageselected = YES;
if (isImageselected == YES) {
myImage = [[UIImageView alloc]initWithFrame:CGRectMake(8.0, 8.0, 95.0, 95.0)];
....
myImage.image = chosenImage; }

Answer 3

You cant not assign object before creating it, so just change your code a little bit like
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
isImageselected = YES;
if (isImageselected == YES) {
myImage = [[UIImageView alloc]initWithFrame:CGRectMake(8.0, 8.0, 95.0, 95.0)];
[self.view addSubView:myImage];
self.addPhotoButton.frame = CGRectMake(106.0, 8.0, 95.0, 95.0);
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
myImage.image = chosenImage;
}
[picker dismissViewControllerAnimated:YES completion:NULL];
}
