如何制作iOS目录? [英] How to make a directory iOS?

问题描述

好吧

因此，我有一个需要更新的Cydia应用程序.我知道Cydia应用程序没有文档文件夹，因此您必须创建一个.这是我之前在iOS 4(在iOS 5中不起作用)上的制作方法:

So I have a Cydia app that I need to update. I am aware with Cydia apps that they don't have a Documents folder, so you have to make one. And here's how I made it before in iOS 4 (which doesn't work on iOS 5):

mkdir("/var/mobile/Library/APPNAME", 0755);
mkdir("/var/mobile/Library/APPNAME/Documents", 0755);

NSString *foofile = @"/var/mobile/Library/APPNAME/Documents/database.db";
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];

if (fileExists == TRUE) {
    NSLog(@"already exists");
} else {
    NSLog(@"doesn't exists");
    NSFileManager *fileManager = [[NSFileManager defaultManager]autorelease];
    NSError *error;
    NSString *documentDBFolderPath = @"/var/mobile/Library/APPNAME/Documents/database.db";

    NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"database.db"];
    [fileManager copyItemAtPath:resourceDBFolderPath toPath:documentDBFolderPath error:&error];

}

我还提供了将数据库文件复制到该文件夹​​的代码.那是行不通的(即使当我通过SSH手动创建文件夹时).

I also included code that copies the database file to that folder, too. That doesn't work (even when I create the folder manually via SSH).

请帮助！谢谢.

推荐答案

这是我创建目录的方法

-(void)createDirectory:(NSString *)directoryName atFilePath:(NSString *)filePath
{
    NSString *filePathAndDirectory = [filePath stringByAppendingPathComponent:directoryName];
    NSError *error;

    if (![[NSFileManager defaultManager] createDirectoryAtPath:filePathAndDirectory
                                   withIntermediateDirectories:NO
                                                    attributes:nil
                                                         error:&error])
    {
        NSLog(@"Create directory error: %@", error);
    }
}
