In iOS7, why selected cell's background color is always gray?

问题

set cell.selectionStyle = UITableViewCellSelectionStyleBlue, or even manually set Blue in storyboard, but neither of them works.

if using setSelectedBackgroundView:, it may work.

But I really want to know why method of `[cell setSelectionStyle:] not work any more in iOS 7? Is it deprecated in iOS 7? If so, why no any waring in Xcode when typing?

回答1:

The method is not deprecated, and it still works—try setting a cell’s selectionStyle to UITableViewCellSelectionStyleNone, for instance. In iOS 7, though, the previous default—UITableViewCellSelectionStyleBlue—now looks like the new default, i.e. gray.
