i have a table.. where i try to show this image in every row.

But when i do
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"BlueLong.png"]];
the outcome is this..

The first row is correct.. but after that its like the upper side of the image gets cutted..?
how can i fix this?
Ty already!
21 and 15 is the center of the Image with the size 42×31 Pixels
EDIT: This should work
