Question

i been cracking my head over this memory leak..

my datasource is mutabledictionary..that i load in the viewdidload. if i dont retain it. i dont have access it it in cellforrowatindexpath. but when i retain it.. it shows up as a memory leak in instruments. i have tried so many different variations.. doesnt seem to get it right.

here is the code the leak is in “dict” and “plistPath”

`
– (void)viewDidLoad {
[super viewDidLoad];

self.navigationController.navigationBarHidden = NO;

self.title = @"Messages & Lists";


NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

[plistPath release];
plistPath = [documentsDirectory stringByAppendingPathComponent:@"general.plist"];

NSFileManager *fileManager = [NSFileManager defaultManager];
[dict release];

if ( [fileManager fileExistsAtPath:plistPath] ) {

    dict = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath] ;


} else {
    dict = [NSMutableDictionary dictionaryWithCapacity:1];

    [dict setObject:@"NO" forKey:@"busyStatus"];
    [dict setObject:@"NO" forKey:@"replyToAll"];
    [dict setObject:@"NO" forKey:@"replyToList"];
    [dict setObject:@"NO" forKey:@"dontReplyToList"];

    [dict writeToFile:plistPath atomically:YES];


}

[tableData release];

tableData = [[NSMutableDictionary alloc] init];

[tableData setObject:[NSArray arrayWithObjects:@"Help",@"Set Default Message",@"Reply To All",[dict objectForKey:@"replyToAll"],nil] forKey:@"1"];
[tableData setObject:[NSArray arrayWithObjects:@"Reply to a List",[dict objectForKey:@"replyToList"],@"List of Contacts",nil] forKey:@"2"];
[tableData setObject:[NSArray arrayWithObjects:@"Don't reply to List",[dict objectForKey:@"dontReplyToList"],@"List of Contacts",nil] forKey:@"3"];


[dict retain];  
[plistPath retain];

}

`

there is no leak the first time the view loads. but if i got back. and then load the view again it leaks.

thanks in advance for anyone who can help me out.

You have to call [dict release] in your view controller’s dealloc method.
