我在我的应用程序目录的 Documents 文件夹中创建了一个文件夹。
我想通过代码重命名该文件夹，但无法理解如何操作。
请帮帮我。

你有没有尝试过？
NString *newDirectoryName = @"<new folder name>";
NSString *oldPath = @"<path to the old folder>";
NSString *newPath = [[oldPath stringByDeletingLastPathComponent] stringByAppendingPathComponent:newDirectoryName];
NSError *error = nil;
[[NSFileManager defaultManager] moveItemAtPath:oldPath toPath:newPath error:&error];
if (error) {
NSLog(@"%@",error.localizedDescription);
// handle error
}

NSString *oldDirectoryPath = @"Type your old directory Path";
NSArray *tempArrayForContentsOfDirectory =[[NSFileManager defaultManager] contentsOfDirectoryAtPath:oldDirectoryPath error:nil];
NSString *newDirectoryPath = [[oldDirectoryPath stringByDeletingLastPathComponent]stringByAppendingPathComponent:newDirectoryname];
[[NSFileManager defaultManager] createDirectoryAtPath:newDirectoryPath attributes:nil];
for (int i = 0; i < [tempArrayForContentsOfDirectory count]; i++)
{
NSString *newFilePath = [newDirectoryPath stringByAppendingPathComponent:[tempArrayForContentsOfDirectory objectAtIndex:i]];
NSString *oldFilePath = [oldDirectoryPath stringByAppendingPathComponent:[tempArrayForContentsOfDirectory objectAtIndex:i]];
NSError *error = nil;
[[NSFileManager defaultManager] moveItemAtPath:oldFilePath toPath:newFilePath error:&error];
if (error) {
// handle error
}
}

使用 moveItemAtPath 应该可以。有时该目录实际上并没有“重命名”，而是真正移动到了另一个地方。在这种情况下，还需要创建目标路径目录结构。这是我正在使用的代码片段，效果很好：
-(BOOL)renameDir:(NSString *)dirPath asDir:(NSString *)newDirPath cleanExisting:(BOOL)clean
{
NSError *error = nil;
NSFileManager *fm = [NSFileManager defaultManager];
if (clean && [fm fileExistsAtPath:newDirPath])
{
[fm removeItemAtPath:newDirPath error:&error];
if (error != nil)
{
NSLog(@"Error while renameDir %@ as %@ :\n%@",dirPath,newDirPath,error);
return NO;
}
}
//Make sure container directories exist
NSString *newDirContainer = [newDirPath stringByDeletingLastPathComponent];
if (![fm fileExistsAtPath:newDirContainer])
{
[fm createDirectoryAtPath:newDirContainer withIntermediateDirectories:YES attributes:nil error:&error];
}
if (error==nil)
{
[fm moveItemAtPath:dirPath toPath:newDirPath error:&error];
}
if (error!=nil)
{
NSLog(@"error while moveItemAtPath : %@",error);
}
return (error==nil);
}

这总是有效的
NSLog (@"Copying download file from %@ to %@", aPath, bPath);
if ([[NSFileManager defaultManager] fileExistsAtPath: bPath]) {
[[NSFileManager defaultManager] removeItemAtPath: bPath
error: &error];
}
if (![[NSFileManager defaultManager] copyItemAtPath: aPath
toPath: bPath
error: &error]){}
if ([[NSFileManager defaultManager] removeItemAtPath: aPath
error: &error]) {}

这是重命名、删除和创建文件的好文章。
// For error information
NSError *error;
// Create file manager
NSFileManager *fileMgr = [NSFileManager defaultManager];
// Point to Document directory
NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
// Rename the file, by moving the file
NSString *filePath2 = [documentsDirectory stringByAppendingPathComponent:@"file2.txt"];
// Attempt the move
if ([fileMgr moveItemAtPath:filePath toPath:filePath2 error:&error] != YES)
NSLog(@"Unable to move file: %@", [error localizedDescription]);
// Show contents of Documents directory
NSLog(@"Documents directory: %@",
[fileMgr contentsOfDirectoryAtPath:documentsDirectory error:&error]);
