我正在访问 OS X 通讯簿,如下所示:

if let book = ABAddressBook.sharedAddressBook() { 
    let people = book.people() as [ABPerson]
    for person in people {
        // Now I want to get the person's image to some variable
        ABPersonCopyImageData(person) // compile error
    }
}

Xcode 说“ABPerson”不能转换为“ABPerson”。

那有什么问题?

在此先感谢,金
