@properties - 内存管理

Question

这段代码对于内存管理是否可以正常运行？

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

谢谢您的回答， 基督教

号作为属性描述符表示，它将保留对象时，它的分配。所以，当你分配它的时候，你将在你的对象中有两个保留，分配给self.object。所以，你必须发布它：

@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; 

祝你好运！
