ios7 :

ios7 下 button.superview.superview .superview 是擷取按鈕所在的cell

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

 2014-10-07 10:23:55.583 NeiHanShe[1407:60b] 2: cell ---- <RadioCell:0x155849d0; baseClass = UITableViewCell; frame = (0 0; 320 70); autoresize = W; layer = <CALayer: 0x1552af80>>

ios7 下 button.superview.superview 是擷取的不是cell對象

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

 2014-10-07 10:22:37.993 NeiHanShe[1396:60b] 2: cell ---- <UITableViewCellScrollView:0x17d2d2e0; frame = (0 0; 320 70); autoresize = W+H; gestureRecognizers = <NSArray: 0x17d2d200>; layer = <CALayer: 

 ios8 :

 ios8下button.superview.superview.superview 擷取的是UITableViewWrapperView對象, 所以點擊不同cell 但擷取的記憶體相等, 這裡就會出問題

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

 2014-10-07 10:27:07.903 NeiHanShe[2791:1186272] 2: cell ---- <UITableViewWrapperView:0x1663bbf0; frame = (0 0; 320 528); gestureRecognizers = <NSArray: 0x1663bb10>; layer = <CALayer: 0x1663bbc0>; contentOffset: {0, 0}; contentSize: {320, 528}>

 2014-10-07 10:27:09.617 NeiHanShe[2791:1186272] 2: cell ---- <UITableViewWrapperView:0x1663bbf0; frame = (0 0; 320 528); gestureRecognizers = <NSArray: 0x1663bb10>; layer = <CALayer: 0x1663bbc0>; contentOffset: {0, 0}; contentSize: {320, 528}>

ios8 下 button.superview.superview 才是擷取按鈕所在的cell

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

 2014-10-07 10:20:50.813 NeiHanShe[2775:1184682] 2: cell ---- <RadioCell:0x16ed6a30; baseClass = UITableViewCell; frame = (0 0; 320 70); autoresize = W; layer = <CALayer: 0x16ea5fc0>> 

 2014-10-07 10:20:52.321 NeiHanShe[2775:1184682] 2: cell ---- <RadioCell:0x16ed6b44; baseClass = UITableViewCell; frame = (0 0; 320 70); autoresize = W; layer = <CALayer: 0x16ea5fc0>>

iOS7與iOS8，從蘋果新更新的iOS712可以看出蘋果的注重點已經不在ios7上面了，iO

iPhone4已經4年了 該是壽終正寢了
 
Ios8 系統介面圖片與ios7有什不同？

差不多，新增了一些內建軟體
