在iOS上写一个文件 [英] Write a file on iOS

问题描述

如何在iOS上编写文件？我正在尝试使用以下代码，但我做错了：

How do I write a file on iOS? I'm trying to do it with the following code but I'm doing something wrong:

char *saves = "abcd";
NSData *data = [[NSData alloc] initWithBytes:saves length:4]; 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *appFile = [documentsDirectory stringByAppendingPathComponent:@"MyFile"];
[data writeToFile:appFile atomically:YES];

我已经在资源上创建了MyFile.txt。

I have created MyFile.txt on resources.

推荐答案

你的代码在我的结尾工作，我刚刚测试过。你在哪里检查你的变化？使用文档目录路径。获取路径 -

Your code is working at my end, i have just tested it. Where are you checking your changes? Use Documents directory path. To get path -

NSLog(@"%@",documentsDirectory);

并从控制台复制路径，然后打开查找器，然后按Cmd + shift + g并粘贴路径，然后打开你的文件

and copy path from console and then open finder and press Cmd+shift+g and paste path here and then open your file
