objective-c - Objective-C：内存泄漏与自动释放的多重分配？

Question

如果我做以下事情，这会导致内存泄漏吗？

SomeClass* tmp;
NSDate* thetmpdate;

tmp = [[[SomeClass alloc] init] autorelease];
thetmpdate = [NSDate date];
// Do something long with tmp and date

tmp = [[[SomeClass alloc] init] autorelease];
thetmpdate = [NSDate date];
// Do something long with tmp and date

tmp = [[[SomeClass alloc] init] autorelease];
thetmpdate = [NSDate date];
// Do something long with tmp and date

Answer 1

不，您发布的代码没有泄漏。当自动释放池被刷新时，所有对象都将被自动释放，无论持有它们的指针的变量是否改变。
