遍历一个目录下的所有文件
首先我们获取用户文档目录路径
1 let manager = FileManager.default 2 let urlForDocument = manager.urls(for: .documentDirectory, in:.userDomainMask) 3 let url = urlForDocument[0] as URL 4 print("---------->(url)")
打印结果：
---------->file:///Users/huanggang/Library/Developer/CoreSimulator/Devices/7B9AE7A4-4838-495B-964D-560DF760F7E1/data/Containers/Data/Application/70D8DA8D-4FEF-4715-B82E-0F40C1BC1B78/Documents/
深度遍历，会递归遍历子文件夹
1 let enumeratorAtPath = manager.enumerator(atPath: url.path) 2 enumeratorAtPath?.skipDescendants() //跳过递归到最近获得的子目录 3 print("enumeratorAtPath: (enumeratorAtPath?.allObjects)")
打印结果：
enumeratorAtPath: Optional([])
