使用Obj-C重命名现有文件 [英] Renaming an existing file with Obj-C

问题描述

我已经看过几次这个问题，但是到目前为止，使用任何后期解决方案都无法成功.我想做的是在应用程序的本地存储中重命名文件(这也是Obj-c的新功能).我可以检索旧路径并创建新路径，但是要真正更改文件名，我必须写些什么?

I've seen this question asked a few times but I have been unable thus far to achieve success using any of the post solutions. What I am trying to do is rename a file in the local storage of an app (also kind of new to Obj-c). I am able to retrieve the old path and create the new path, but what would I have to write in order to actually change the files name?

到目前为止，我有:

- (void) setPDFName:(NSString*)name{
    NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                   NSUserDomainMask, YES);
    NSString* initPath = [NSString stringWithFormat:@"%@/%@",[dirPaths objectAtIndex:0], @"newPDF.pdf"];
    NSString *newPath = [[NSString stringWithFormat:@"%@/%@",
                          [initPath stringByDeletingLastPathComponent], name]
                         stringByAppendingPathExtension:[initPath pathExtension]];
}

推荐答案

NSError *error = nil;
[[NSFileManager defaultManager] moveItemAtPath:initPath toPath:newPath error:&error];
