@properties - 內存管理

Question

這段代碼對於內存管理是否可以正常運行？

@property (nonatomic, retain) id object; 
... 
id anObject = [[Object alloc] init]; 
self.object = anObject; 
id otherObject = [[Object alloc] init]; 
self.object = otherObject; 

謝謝您的回答， 基督教

號作爲屬性描述符表示，它將保留對象時，它的分配。所以，當你分配它的時候，你將在你的對象中有兩個保留，分配給self.object。所以，你必須發佈它：

@property (nonatomic, retain) id object; 
... 
id anObject = [[Object alloc] init]; 
self.object = anObject; 
[anObject release]; 

id otherObject = [[Object alloc] init]; 
self.object = otherObject; 
[otherObject release]; 
... 
at dealloc: 
self.object = nil; 

祝你好運！
