具有contentMode UIViewContentModeScaleAspectFit的UIImageView的UILabel

Question

I need to set a label that has a custom background color on top of a UIImageView. The problem is that I want it's width to be the exact size as the image from the image view is. This is the code so far:

UIImageView *pictureV = [[UIImageView alloc] initWithFrame:CGRectMake(pictureX, 0, pictureSize.width, pictureSize.height)];
pictureV.image = self.picture.image;
pictureV.contentMode = UIViewContentModeScaleAspectFit;

And the label:

UILabel *lblName = [[UILabel alloc]init];
lblName.backgroundColor=[UIColor colorWithRed:0.5 green:0.5 blue:0.5 alpha:0.6];
lblName.frame = CGRectMake(pictureV.bounds.origin.x, pictureV.bounds.origin.y + pictureV.bounds.size.height - 30, self.picture.image.size.width, 30);
[lblName setText:self.pictureNote.text];
[lblName setTextAlignment:UITextAlignmentCenter];
[lblName setTextColor:[UIColor whiteColor]];
[pictureV addSubview:lblName]

When setting the contentMode as UIViewContentModeScaleAspectFit, some images are smaller than my UIImageView and I can't seem to make the label's width the same size.

If you use UIViewContentModeScaleAspectFit, the image will not take the full size of UIImage View. Instead of this set your pictureV's contentMode property to UIViewContentModeScaleToFill , then the image will take the whole size of your imageView
