读写plist文件

写入plist文件

NSString *plistPath = @"/private/var/mobile/Media/iTunes_Control/iTunes/Ringtones.plist";

            NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];

            [[dictionary objectForKey:@"Ringtones"] setObject:ringtones forKey:ringName];

            if (![dictionary writeToFile:plistPath atomically:YES]) {

                NSLog(@"The new ringtone write to file failured!");

            }

 

 

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"Setup" ofType:@"plist"];    //把Setup.plist文件放到项目中就ok了，文件名随意。

    NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:plistPath]; //根据plistPath内容，将Setup.plist内容读入到一个NSMutableDictionary中 //如果仅仅是读取<u><font color="\"red\"">plist</font></u>内容并显示的话，此处用NSDictionary即可。

     

    //将服务器信息填入视图

    serverIP    = [[dictionary objectForKey:@"ServerSetup"] objectForKey:@"Server"];  //读取"ServerSetup"层 的"Server"关键字下的内容

    serverPort  = [[dictionary objectForKey:@"ServerSetup"] objectForKey:@"Port"];

     

   //显示读取的内容。

    UIAlertView* alert =[[UIAlertView alloc] initWithTitle:@"IP地址" message:serverIP delegate:Nil cancelButtonTitle:@"OKey" otherButtonTitles:nil, nil];

    [alert show];

     

//将读取到的内容 放入变量中

    AccelemeterX = (int)[[dictionary objectForKey:@"Accelerometer"] objectForKey:@"X"];  

    AccelemeterY = (int)[[dictionary objectForKey:@"Accelerometer"] objectForKey:@"Y"];  

    AccelemeterZ = (int)[[dictionary objectForKey:@"Accelerometer"] objectForKey:@"Z"];  

    NSLog(@"x=%@,y=%@,z=%@",AccelemeterX,AccelemeterY,AccelemeterZ);

  

 

 

 

    //如下进行写<u><font color="\"red\"">plist</font></u>操作，注意写<u><font color="\"red\"">plist</font></u>操作，必须使用NSMutableDictionary才行

 NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"Setup" ofType:@"plist"];             //把Setup.plist文件放到项目中就ok了，文件名随意。

 NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];   //根据plistPath内容，此处必须使用NSMutableDictionary

    [[dictionary objectForKey:@"ServerSetup"] setValue:@"abc.abc.abc.abc" forKey:@"Server"];          //将<u><font color="\"red\"">plist</font></u>文件中“ServerSetup”下的“Server”关键字的内容改为“abc.abc.abc.abc”  

    [dictionary writeToFile:plistPath atomically:YES];    //要想将修改内容写入文件，必须执行这步，否则即使修改了也是没有落实到磁盘上的。
