Does -setNeedsLayout get called even for dequeued reusable cells? If so, the cell will already have the label added to the content view, and you will draw it twice, making it blurry. You can inefficiently solve this by removing all of the content view's subviews before you add your subview:

for (UIView *subview in [[self contentView] subviews]) {
     [subview removeFromSuperview];
}

A better solution would be to provide properties on your cell subclass to let you modify the content of a reused cell as-needed, rather than rebuilding its view hierarchy from scratch.
