Assign string value as a image name

Question

I have a string variable(imageStr) in which I have name of an image I am fetching from sqlite database. How can I assign that string variable as an image name to a imageview?

Code:

UIImageView *imageHolder = [[UIImageView alloc] initWithFrame:CGRectMake(150, 11, 50, 25)];
UIImage *image = [UIImage imageNamed:imageStr];
imageHolder.image=image;
NSLog(@"image in mediView:%@",imageHolder.image);

In the log I am getting NULL value. If I print just "imageStr" then it is giving me string value.

it works if you have same image name in imageStr with image extemsion like [UIImage imageNamed:@"openTree.png"] — Anurag Soni, Aug 27 '13 at 13:00

Please, in order to get useful answers, edit your question and show us what are you getting when you print "imageStr" — LuisEspinoza, Aug 27 '13 at 22:22
Are you have image (*.png or *.jpg) with same name as saved in imageStr-variable? If imageStr have a difference in name, your image will be a nil. — frankWhite, Aug 27 '13 at 12:54

NSLog(@"image in mediView:%@",imageHolder.image);

The above line of code is trying to print a UIImage, which makes no sense because neither UIImageView or UIImage have knowledge of what the name of the image is. What you need to do is subclass UIImageView and add a property that saves this information.

Update: Shan's link above is pretty helpful.
