※ 引述《denru01 (阿儒)》之銘言：
: [cell.contentView addSubview:textField];
查到的addSubView，他會做retain的動作，而在removeFromSuperview時會做release。
addSubview:
Adds a view to the receiver’s subviews so it’s displayed above its siblings.
- (void)addSubview:(UIView *)view
Discussion
This method also sets the receiver as the next responder of view. The
receiver retains view. If you use removeFromSuperview to remove view from the
view hierarchy, view is released. If you want to keep using view after
removing it from the view hierarchy (if, for example, you are swapping
through a number of views), you must retain it before invoking
removeFromSuperview.

1F：→ atst2:波我剛回頭看了一下,你應該不是因為textField crash 08/05 10:13
2F：→ atst2:而是因為cell 08/05 10:13
3F：→ atst2:把cell的autorelease拿掉吧 08/05 10:13
4F：→ atst2:更正,上面當我沒說,沒看到if....= = 08/05 10:14
5F：推 denru01:因為我只要一加[textField release]就會crash 08/05 11:21
6F：→ denru01:錯誤訊息又說似乎是送信息給已被釋放的物件 08/05 11:22
7F：→ atst2:@property(nonatomic, assign) ---會不會是這個問題? 08/05 12:01
8F：→ atst2:TextField release時，應該會同時release delegate, 08/05 12:02
9F：→ atst2:因此有可能造成release兩次. 08/05 12:02
10F：→ atst2:你可以做個實驗，將delegate設成別人,而非self. 08/05 12:03
11F：→ atst2:看是不是還會有問題?(記得設完後不要做release動作) 08/05 12:04
12F：→ zonble:setDelegate 是不會 retain 的 08/05 15:11
