奇怪的地方是对象的地址不同

2015-09-19 13:31:15.309 test[80165:2126493] -[TestObj dealloc] TestObj 0x7fff59b500f8

求高人解释

NSLog (@"%s %@ %p", __PRETTY_FUNCTION__, self.class, &self );
改为
NSLog (@"%s %@ %p", __PRETTY_FUNCTION__, self.class, self );

给你写个例子，再不明白就没办法了···google 关键词：指针的指针··

TestObj *obj = [TestObj new];

NSLog (@"obj->%p",obj );
NSLog (@"&obj->%p",&obj );

TestObj *obj2 = obj;
NSLog (@"obj2->%p",obj2 );
NSLog (@"&obj2->%p",&obj2 );
