objective c - Appending some data to a plist -

i'm creating app allows log board game plays. i'm storing logs in plist , i'm trying figure out how append plist. think understand logic i'm having trouble putting code.

my plist looks so:

right i'm trying believe overwrite plist file instead of appending

//get path root directory nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory,nsuserdomainmask, yes);  nslog(@"paths: %@",paths);  //get path documents directory nsstring *documentspath = [paths objectatindex:0]; nslog(@"documentspath: %@",documentspath);  //get path logs.plist file nsstring *plistpath = [documentspath stringbyappendingpathcomponent:@"logs.plist"];   //create dictionary values nsdictionary *plistdict = [nsdictionary dictionarywithobjects:[nsarray arraywithobjects:mylogtitle, name, players, mynotes, nil] forkeys:[nsarray arraywithobjects:@"log title",@"name",@"players","notes", nil]];  //write out data  [plistdict writetofile:plistpath atomically:yes]; 

any appreciated.

try this

nsstring *path = [[nsbundle mainbundle] pathforresource: @"data" oftype: @"plist"];  nsdictionary *dict = [nsdictionary dictionarywithcontentsoffile: path]; nslog(@"dictbeforeappending..%@",dict);  //getting previous array..... nsmutablearray *prevarray = [[nsmutablearray alloc]init]; prevarray = [[dict valueforkey:@"root"] valueforkey:@"logs"]; nslog(@"prevarray..%@",prevarray);  // add new stuff old stuff.....  nsmutablearray *players =[[nsmutablearray alloc]initwithobjects:@"newplayer1",@"newplayer2",@"newplayer3", nil];//1 nsdictionary *newobject = [nsdictionary dictionarywithobjects:[nsarray arraywithobjects:@"logtiltle2", @"krish", players, @"it more fun", nil] forkeys:[nsarray arraywithobjects:@"log title",@"name",@"players",@"notes", nil]];//2  nsmutablearray *newarray = [[nsmutablearray alloc]init]; [newarray addobject:newobject]; (int i=0;i<[prevarray count];i++){     [newarray addobject:[prevarray objectatindex:i]]; }  //set values plist...... nsmutabledictionary *allitemsdict = [[nsmutabledictionary alloc]init]; nsmutablearray *logs = [[nsmutablearray alloc]initwitharray:newarray]; [allitemsdict setobject:logs forkey:@"logs"];  nsmutabledictionary *root = [[nsmutabledictionary alloc]init]; [root setobject:allitemsdict forkey:@"root"];  // now, write plist: [root writetofile:path atomically:yes];  nsdictionary *dictafterappending = [nsdictionary dictionarywithcontentsoffile: path]; nslog(@"dictafterappending..%@",dictafterappending); 

if stuck @ anywhere please let me know dude...
