ios7 =< System Version < ios8 下 button.superview.superview .superview 是获取按钮所在的cell
app

NSLog(@"2: cell ---- %@", button.superview.superview.superview);spa

ios7 =< System Version < ios8 下 button.superview.superview 是获取的不是cell对象
内存

NSLog(@"2: cell ---- %@", button.superview.superview);io

ios8 > System Version || ios7 < System Version :ios7

ios8 > System Version || ios7 < System Version 下button.superview.superview.superview 获取的是UITableViewWrapperView对象, 因此点击不一样cell 但获取的内存相等, 这里就会出问题ios8

NSLog(@"2: cell ---- %@", button.superview.superview.superview
