7^F推leondemon:看起來跟string的類別無關直接貼完整code或是找人debug05/27 19:53

8^F→leondemon:先clean再run analyze 找看看是不是中間有nil的物件產生05/27 19:56

9^F→leondemon:自己用NSLog去trace一下每行的物件是否存在值是否正常05/27 19:57

10^F推leondemon:如果沒發生run-time error但是你assign的值卻不正常05/27 19:59

11^F→leondemon:通常都是Null Object Design Pattern的關係...05/27 20:00

12^F→leondemon:因為你可以對nil object傳送message所以你可能會誤認bug05/27 20:02

4^F推leondemon:http://tinyurl.com/44nbzuw 這本很適合入門者...05/06 00:56

5^F→leondemon:當初我也是念完Obj-C就從這本開始下手 (iOS 2-iOS 3)05/06 00:57

6^F→leondemon:如果有英聽&GUI介面開發的底子 Standford的課程可以看看05/06 00:59

7^F→leondemon:不過像我完全沒程式底子的門外漢柳丁書大概是最好選擇05/06 01:00

1^F推leondemon:謝謝Z大！CALayer的delegate是否不能是UIView?04/13 23:03

2^F→leondemon:另外問一下為什麼要push/pop CGContextRef?04/13 23:03

10^F→leondemon:嗯因為我把delegate設為UIView App就會死當 =.=04/13 23:31

11^F→leondemon:目前好像別人也是遇到這個情形... Orz04/13 23:31

1^F推leondemon:謝謝Z大！但是我希望sibling之間不需要知道彼此存在04/13 22:08

2^F→leondemon:而又不需要superview去控管這些subviews04/13 22:09

3^F→leondemon:希望把所有responsibility都丟給原本top view本身...04/13 22:09

4^F→leondemon:原本是希望top view去觀察是否有sibling view變動...04/13 22:10

5^F→leondemon:但是似乎好像是沒有辦法 (還是我沒找到???)04/13 22:10
