picture taken with camera doesn't resize in uiimageview

Question

My code

- (IBAction)takePhoto:(UIButton *)sender {
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
    UIImagePickerController *picker = [UIImagePickerController new];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

    [self presentViewController:picker animated:YES completion:nil];
}else{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"ERROR!" message:@"Device has no camera!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
}
}

and the delegate

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.userImage.image = chosenImage;

[picker dismissViewControllerAnimated:YES completion:NULL];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

[picker dismissViewControllerAnimated:YES completion:NULL];

}

Well, thats pretty simple and basic. My problem is that after assigning my image to the UIImageView I have (which has a pinned/fixed width and height) instead of resizing itself to the size of the uiimageview it stretches throughout my whole view, working more as a background that an image placed where it should be. Again, the width and height of my uiimageview has been pinned. Can anybody help? thanks

The contentMode of your UIImageView should be UIViewContentModeScaleAspectFit , instead of UIViewContentModeCenter as it seems to be.

If you need to change the content mode on the fly, just add this line:

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.userImage.image = chosenImage;

    // Add this line
    self.userImage.contentMode = UIViewContentModeScaleAspectFit;

    [picker dismissViewControllerAnimated:YES completion:NULL];
}
