You need enable cell codes for if indexPath.row == videoName.count {} to have cell's settings symmetrically
if indexPath.row == videoName.count {
....
// Enable cell code
if dataVideoName.contains(cell.video_name.text!)
{
cell.img.alpha = 1
cell.btn_add.alpha = 1
cell.viewer.alpha = 1
cell.video_name.alpha = 1
cell.artist_name.alpha = 1
cell.userInteractionEnabled = true
}
} else {
....
// Disable cell code
if dataVideoName.contains(cell.video_name.text!)
{
cell.img.alpha = 0.50
cell.btn_add.alpha = 0.50
cell.viewer.alpha = 0.50
cell.video_name.alpha = 0.50
cell.artist_name.alpha = 0.50
cell.userInteractionEnabled = false
}
}
