问题描述

我正在开发一个应用程序.为此，我尝试使用以下代码更新plist文件.

I am developing one application.In that i am trying to update the plist file using below code.

 plist_path=[[NSBundle mainBundle]pathForResource:@"Configurationfile" ofType:@"plist"];
 config_dict=[[NSMutableDictionary alloc]initWithContentsOfFile:plist_path];
[config_dict setValue:textField.text forKey:@"ServerURL"];
NSLog(@"%@",config_dict);
[config_dict writeToFile:plist_path atomically:YES];

但是它不起作用.但是NSlog显示字典中每个键的正确值.请帮助我如何更新plist文件.

But it's not working.But NSlog showing the correct values for every key in the dictionary.Please help me how to update the plist file.

推荐答案

您无法更新应用捆绑包中的文件.而是将文件复制到工作目录并在那里进行更新.

You cannot update the files within the app bundle. Instead copy the files to a working directory and update them there.
