我是 iPhone 新手，我有一个小疑问，我在下面的类中有一个方法
-(void)bookNamesWhichAreInDownloadedQueue:(NSMutableArray *)receivedBookNamesWhichAreInDownloadedQueue{
NSLog(@"receivedBookNamesWhichAreInDownloadedQueue is %@",receivedBookNamesWhichAreInDownloadedQueue);
bookNamesWhichAreInDownloadedQueue = receivedBookNamesWhichAreInDownloadedQueue;
NSLog(@"bookNamesWhichAreInDownloadedQueue is %@",bookNamesWhichAreInDownloadedQueue);
}
这里的 bookNamesWhichAreInDownloadedQueue 是一个 NSMutableArray，它包含一些数据。我想在同一个类的另一个方法中使用该数据检索这个数组，这是怎么可能的。如果有人知道这一点，请帮助我
创建一个返回的方法NSMutableArray:
-(NSMutableArray*)bookNamesWhichAreInDownloadedQueue:(NSMutableArray *)receivedBookNamesWhichAreInDownloadedQueue{
NSLog(@"receivedBookNamesWhichAreInDownloadedQueue is %@",receivedBookNamesWhichAreInDownloadedQueue);
bookNamesWhichAreInDownloadedQueue = [[NSMutableArray alloc] initWithArray:receivedBookNamesWhichAreInDownloadedQueue];
NSLog(@"bookNamesWhichAreInDownloadedQueue is %@",bookNamesWhichAreInDownloadedQueue);
return bookNamesWhichAreInDownloadedQueue;
}
现在您可以从要检索的方法中调用此方法NSMutableArray!!
一切顺利！！！
