plist檔案是標準的xml檔案，在cocoa中可以很簡單地使用。這裡介紹一下使用方法：
以下**在mac和iphone中均適用。
寫入plist檔案：
nsmutabledictionary
* dict
=[ [
nsmutabledictionary
alloc
]initwithcontentsoffile
:@"/sample.plist"
];
[ dict
setobject
:@"yes"
forkey
:@"restartspringboard"
];
[ dict
writetofile
:@"/sample.plist"
atomically
:yes
];
讀取plist檔案：
nsmutabledictionary
* dict
=[ [
nsmutabledictionary
alloc
]initwithcontentsoffile
:@"/sample.plist"
];
nsstring
*object
=[ dict
objectforkey
:@"restartspringboard"
];
//讀plist 檔案 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"]];
//從nsmutabledictionary 中構建 plist 檔案
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"]];
