我怎么打算释放从类方法返回的数组？ [英] How am I meant to release an array returned from a class method?

问题描述

我有一段代码，它调用返回 NSMutableArray 的方法：

I have a section of my code which calls a method returning an NSMutableArray like so:

+(NSMutableArray *)method {

NSMutableArray *rgb = [[NSMutableArray alloc] initWithObjects:....., nil];

    return rgb;

}

在 return 之后放置 [rgb release]; 似乎不起作用。将它放在 return 之前会使我的应用程序崩溃。同时插入 autorelease 会使我的应用程序崩溃。建议？

It gives me a leak every time it's called. Putting [rgb release]; after return doesn't appear to work. Putting it before return makes my app crash. Also putting in an autorelease makes my app crash. Suggestions?

推荐答案

+(NSMutableArray *)method {
    NSMutableArray *rgb = [[NSMutableArray alloc] initWithObjects:....., nil];
    return [rgb autorelease];
}

或者：

+(NSMutableArray *)method {
    NSMutableArray *rgb = [NSMutableArray arrayWithObjects:....., nil];
    return rgb;
}

如果这仍然崩溃，那么问题很可能在这个方法之外，不在内。

IF this still crashes, then the problem is most likely outside of that method, not within.
