从同一个类的另一个方法中检索一个NSMutableArray

Question

我是iphone的新手，我有一个小疑问，就是我在下面的课程中有一个方法

-(void)bookNamesWhichAreInDownloadedQueue:(NSMutableArray *)receivedBookNamesWhichAreInDownloadedQueue{
    NSLog(@"receivedBookNamesWhichAreInDownloadedQueue is %@",receivedBookNamesWhichAreInDownloadedQueue);
    bookNamesWhichAreInDownloadedQueue = receivedBookNamesWhichAreInDownloadedQueue;
    NSLog(@"bookNamesWhichAreInDownloadedQueue is %@",bookNamesWhichAreInDownloadedQueue);
}

这里bookNamesWhichAreInDownloadedQueue是一个NSMutableArray，它包含一些数据。我想用同一个类中的另一个方法检索这个数据的方式是怎么回事。如果有人知道这个请帮帮我

Answer 1

创建一个返回NSMutableArray：

的方法

-(NSMutableArray*)bookNamesWhichAreInDownloadedQueue:(NSMutableArray *)receivedBookNamesWhichAreInDownloadedQueue{
    NSLog(@"receivedBookNamesWhichAreInDownloadedQueue is %@",receivedBookNamesWhichAreInDownloadedQueue);
    bookNamesWhichAreInDownloadedQueue = [[NSMutableArray alloc] initWithArray:receivedBookNamesWhichAreInDownloadedQueue];
    NSLog(@"bookNamesWhichAreInDownloadedQueue is %@",bookNamesWhichAreInDownloadedQueue);
    return bookNamesWhichAreInDownloadedQueue;
}

现在，您可以从要重试NSMutableArray !!

的方法中调用此方法

一切顺利!!!
