Avoid memory leak when using array element in iPhone app

Question

NSString *hostStr2 = [[NSString alloc] initWithFormat:@"http://%@/getplaylist.php?ip=%@",yourip,restip];
NSLog(@"XMLAppDelegate checkstatusthread call to php for status,playlist and nowplaying XML's %@" ,hostStr2);
NSData *dataURL2 =[NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr2 ]];  
[hostStr2 release];

NSString *playlistdata=[[NSString alloc] initWithData:dataURL2 encoding:NSASCIIStringEncoding];
NSArray *ipItemsArray;

// memory leak showing at below line    
ipItemsArray =[playlistdata componentsSeparatedByString:@"|^|"];

[playlistdata release];

What I am storing in ipItemsArray is a big XML data separated with a delimiter '|^|'. The problem is when i run this it is giving memory leaks in this array. Is there any other type of array that we can use or can someone better optimize this code so that i can get rid of the memory leaks happening.

最好将内存分配给该数组。然后在dealloc方法中释放它
