Objective-C:内存是否泄漏,多次分配自动释放？

Question

如果我做了以下事情,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.刷新自动释放池时,无论是否更改保持其指针的变量,都将自动释放所有对象.
