after setting the color give shadow radius,offset and opacity, convert the color to rgba and use this

  cell.layer.shadowColor = [UIColor colorWithRed:0.2471 green:0.3176 blue:0.7098 alpha:1.0].CGColor;
  cell.layer.shadowRadius=10;
  cell.layer.shadowOffset=CGSizeMake(1, 1);
  cell.layer.shadowOpacity=1;

if you want to use hex color only use this How can I create a UIColor from a hex string?

Answer 2

you need to set shadow first

cell.layer.shadowRadius=8;
cell.layer.shadowOffset=CGSizeMake(-1, -1);// this make top left shadow
cell.layer.shadowOpacity=1;
cell.layer.shadowColor = [UIColor colorWithRed:0.2471 green:0.3176 blue:0.7098 alpha:1.0].CGColor;
