iOS复制目录包括子目录 [英] iOS copy directories including subdirectories

问题描述

我使用iOS文件夹名为temp，分配的子目录包含远程url下载的文件。现在我需要将temp目录及其所有内容复制到main文件夹（覆盖以前创建的现有文件夹）。我知道如何处理文件，但如何复制整个目录？谢谢

I am working with iOS document folder called "temp" that allocates subdirectories that contain files dowloaded from remote url. Now I need to copy "temp" directory and all its contents to "main" folder (overwrite existing that was previously created). I know how to handle files but how to copy whole directory? Thank you

推荐答案

您可以使用相同的 NSFileManager 和爱目录以及。例如：

You can use the same NSFileManager methods that you know and love for directories as well. For example:

if ([[NSFileManager defaultManager] fileExistsAtPath:pathToTempDirectoryInMain]) {
    [[NSFileManager defaultManager] removeItemAtPath:pathToTempDirectoryInMain error:nil];
}
NSError *copyError = nil;
if (![[NSFileManager defaultManager] copyItemAtPath:pathToTempDirectory toPath:pathToTempDirectoryInMain error:&copyError]) {
    NSLog(@"Error copying files: %@", [copyError localizedDescription]);
}
