阅读更多关于 UITableViewCell checkmark change on select

问题 Am I correct in thinking that to change the checkmark for "on" to "off", I must change the CellAccessoryType between none and checkmark on the didSelectRowAtIndexPath ? Because I have done this but I have noticed the behaviour is not perfectly identical to like the checkmark cells on the auto lock settings on the iphone.
