plist文件是标准的xml文件，在cocoa中可以很简单地使用。这里介绍一下使用方法：

以下代码在Mac和iPhone中均适用。

写入plist文件：

1.  NSMutableDictionary \* dict = \[ \[ NSMutableDictionary alloc \] initWithContentsOfFile :@"/Sample.plist" \] ;
2.  \[ dict setObject : @"Yes" forKey : @"RestartSpringBoard" \] ;
3.  \[ dict writeToFile : @"/Sample.plist" atomically : YES \] ;

读取plist文件：

1.  NSMutableDictionary \* dict = \[ \[ NSMutableDictionary alloc \] initWithContentsOfFile :@"/Sample.plist" \] ;
2.  NSString \* object = \[ dict objectForKey : @"RestartSpringBoard" \] ;

//读plist 文件

到 NSMutableDictionary 中  
  
dictplist = \[\[NSMutableDictionary alloc \] initWithContentsOfURL:\[NSURL fileURLWithPath:path\]\];  
  
\[dictplist setObject:@"testOne" forKey:@"key1"\];  
  
NSLog(\[dictplist objectForKey:@"key1"\]);  
  
NSArray \*array = \[\[NSArray alloc\] initWithObjects:@"item1",@"item2",@"item3",nil\];  
\[dictplist setObject:array forKey:@"arrayitemtest"\];  
  
\[dictplist writeToFile:plistPath atomically:YES\];  
  
NSString \*name = \[dictplist objectForKey:@"name" \];  
NSLog(name);  
  
arraylist = \[\[NSMutableArray alloc\] initWithArray:\[dictplist objectForKey:@"arrayitemtest"\]\];  
  
  
//从NSMutableDictionary 中构建 plist 文件  
  
NSArray \*array = \[\[NSArray alloc\] initWithObjects:@"item1",@"item2",@"item3",nil\];  
dictplist = \[\[NSMutableDictionary alloc \] init\];  
\[dictplist setObject:@"nameOne" forKey:@"name"\];  
  
\[dictplist setObject:array forKey:@"item"\];  
  
\[dictplist writeToFile:plistPath atomically:YES\];  
//arraylist = \[\[NSMutableArray alloc\] init\];  
//\[arraylist addObject:\[dictplist objectForKey:@"name"\]\];  
  
arraylist = \[\[NSMutableArray alloc\] initWithArray:\[dictplist objectForKey:@"item"\]\];
