要在您的应用程序库目录中创建一个新目录，请使用此...

// Generate the path to the new directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *newDirectory = [NSString stringWithFormat:@"%@/new", [paths objectAtIndex:0]];

// Check if the directory already exists
if (![[NSFileManager defaultManager] fileExistsAtPath:newDirectory]) {
    // Directory does not exist so create it
    [[NSFileManager defaultManager] createDirectoryAtPath:newDirectory withIntermediateDirectories:YES attributes:nil error:nil];
}
