ios - Why can't you set the cell.selectionStyle = UITableViewCellSelectionStyleBlue?

I have seen the following questions, but non explain that while you can simply set cell.SelectedStyle to UITableViewCellSelectionStyleGray or UITableViewCellSelectionStyleNone, you can't set it selectionStyle to UITableViewCellSelectionStyleBlue.

They just offer a hack without explaining. I simply want to know the why so that I can better understand objective-c

UITableViewCellSelectionStyleBlue is not working

ios7 UITableViewCell selectionStyle won't go back to blue

Cannot change UITableView blue highlight color

Your not going to like the answer then. As of iOS 7, setting

cell.selectionStyle = UITableViewCellselectionStyleBlue;

will now give you gray. Apple got rid of it in iOS 7, so now selectionStyleBlue no longer exists as blue.. it is gray.

Here is the quote from Apple's Documentation of the UITableViewCell Class Reference:

  • Blue

The cell has a default background color when selected.

In iOS 7, the selection color is no longer blue. Use UITableViewCellSelectionStyleDefault instead.

Available in iOS 2.0 and later.

Of course, as I'm sure you have found, you can create a UIView and set it as the background to simulate a blue selection.

Here is a link for that approach: UITableView cell blue highlight on selection

Edit:

Just to be clear. UITableViewCellSelectionStyleBlue makes the selection style gray.

There is no default method of UITableViewCell that makes selection style a blue color.

In order to make selection style any color other than the default gray, you have to create a custom UIView like in the link I provided.
