Question

这应该是如此简单，但我正在努力解决它。我想要做的就是将NSURL文件从其位置复制到我的应用程序文档目录。我不想重命名该文件，并希望保留相同的名称。请注意，此文件来自电子邮件附件。

这是我到目前为止的代码

-(BOOL)application:(UIApplication *)application
           openURL:(NSURL *)url
 sourceApplication:(NSString *)sourceApplication
        annotation:(id)annotation {
    if (url != nil && [url isFileURL])
    {
        NSLog(@"url: %@ ...", url);

        NSFileManager *fileManager = [NSFileManager defaultManager];
        NSError *error;

        NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask ,YES);
        NSString* documentsPath = [paths objectAtIndex:0];

        //Not sure what to do here. I could parse URL and get the last string out of it
// which is the file name but I am not sure that's easiest way to do things.
        //[fileManager copyItemAtURL:url toURL:backupDir error:&error];

        NSLog(@"Email Copy Error: %@ ...", error);

    }
    return YES;
}

我认为你已经走在了正确的道路上（！）。创建目标路径来自目标目录和url的最后一个路径组件：

NSString *destPath = [documentsPath stringByAppendingPathComponent:[url lastPathComponent]];

并将文件从源复制到目标：

[fileManager copyItemAtPath:[url path] toPath:destPath error:&error];

NSFileManager将NSURL复制到应用程序文档目录
