返回Objective-C对象时的内存管理 [英] Memory management when returning an Objective-C object

问题描述

在Objective-C中，如果我有一个分配和初始化对象的方法，然后将其返回，那么在哪里/如何释放它?

In Objective-C, if I have a method in which I allocate and initialize an object, then return it, where/how do I release it?

例如，假设我有一个创建对象的方法:

for example, let's say I have a method where I create an object:

- (void)aMethod {
    UIView *aView = [self createObject];
}

- (UIView *)createObject {
    UIView *returnView = [[UIView alloc] initWithFrame:CGRectZero];
    return returnView;
}

何时释放该对象?还是我会自动释放它?

When do I release this object? Or would I just autorelease it?

推荐答案

- (void)aMethod {
    UIView *aView = [self createObject];
}

- (UIView *)createObject {
    UIView *returnView = [[UIView alloc] initWithFrame:CGRectZero];
    [returnView autorelease];
    return returnView;
}
