assign delegate中文 在 [心得] delegate你必須知道的事情- 精華區MacDev 的推薦與評價
blog圖文版: https://goo.gl/010l5
當你開始寫iOS程式不久,應該開始面對到很多的delegate,
不管是用別人的library或是自己寫library,可能都逃不了delegate。
為了怕有些人不知道什麼是delegate,在這邊簡單的介紹一下,
delegate中文叫做委託,通常會用在class內部把一些事件處理"委託"給別人去完成。
舉個例子,XML Parser可能他知道怎麼parse xml,
但是parse到的東西要怎麼處理xml parser可能不知道。
所以NSXMLParser就提供了一個NSXMLParserDelegate給client去實作,
當parse到某個element的時候,就callback delegate所定義的message,
讓他client自己去決定怎麼去處理這個element。
好吧,我承認我解釋的很模糊,不過我這篇本來就不是要你搞懂什麼是delegate,
而是針對使用或是設計delegate的時候,可能會要注意的事情。
在我們的class中設計delegate的時候,我們通常會有幾個注意事項。
假設我的class叫做MyClass,
那我們可能會有定義一個MyClassDelegate這個protocol當作我的delegate protocol。
而MyClass中我們可能是這樣寫。
@protocolMyClassDelegate <NSObject>
- (void) myClassOnSomeEvent:(MyClass)myClass
@end
@interface MyClass
{
id<MyClassDelegate> _delegate;
}
@property (nonatomic, assign) delegate;
@end
上面的code我們注意到我們定義的delegate此property是定義為
@property (assign)
為什麼我們不用retain而要用assign呢?
原因就是在於iOS的reference counting的環境中,
我們必須解決circular count的問題。
讓我們來寫寫我們平常都怎麼用delegate的,下面的code我想大家應該不陌生
- (void)someAction
{
myClass = [MyClass new];
myClass.delegate = self;
....
}
這邊很快的就出現circular reference了
假設上面的code是寫在一個myViewController的物件當中,
之後一旦myViewController的reference count變成1的時候,
myViewController跟myClass這兩個兄弟兩只剩下互相retain,那就變成了孤島,
也就因此造成了memory leak!!!
也因為這樣,iOS官方文件才會要建議我們所以的delegate都要用assign property。
也就是所謂"weak reference"的property,
他的特色就是雖然會持有對方的reference,但是不會增加retain count。
如此下來,當myViewController的retain count變成0,則會dealloc。
同時在dealloc中,也一併把myClass release,則myClass也跟著被release。
- (void)dealloc
{
[myClass release];
[super dealloc];
}
事情就結束了嗎? 還沒有唷...
這邊還有一個大家常常忘記的重點,那就是上面的dealloc這樣寫會有潛在危險。
應該要改成這樣
- (void)dealloc
{
myClass.delegate = nil;
[myClass release];
[super dealloc];
}
你可能會很納悶,myClass不是馬上就會被release了嗎?
幹嘛要先把他的delegate設成nil?
那是因為我們假設myClass會馬上會被dealloc,
但是現實狀況這個是不一定的,
有可能裡面內部有建個NSURLConnection,
或是正在做某件事情而讓其他物件也retain myClass。
如果myClass沒有馬上dealloc,
那他的myClass.delegate不就正指向一個不合法的位置了嗎?
(此種pointer稱作dangling pointer)
解決方法是在MyViewController的dealloc中,在release myClass之前,
要先把原本指向自己的delegate改設成nil,這樣才可以避免crash發生。
在我之前寫的project,很大一部份的crash都是這樣造成的,
因為這個問題通常不是每次都發生,但是發生的時候確很難在重新複製,
所以不可不慎啊。
但是很興奮的是到了iOS5中的Automatic Reference Counting這個問題可以有所改善。
在ARC中提出了一個新的weak reference的概念來取代原本的assign,
weak reference指到的物件若是已經因retain count歸零而dealloc了,
則此weak reference也自動設成nil。
而原本舊的這種assign的作法,在ARC中叫做__unsafe_unretained,
這只是為了相容iOS4以下的版本。
回顧重點:
如果你是寫library給別人用的,記得把你的delegate設成assign property,
這樣才不會造成circular reference
當你是要始用別人的library,記得在你自己dealloc的時候,把delegate設成nil,
以避免crash的事情發生。
