Solved:
Hi,

Can you please help me in this, I have following condition

1) Declared an array in .h file.
2) Created property and synthesized it
3) In viewWillAppear allocated memory to it

pickerList = [[NSMutableArray alloc] init];

4) Read data from database and stored objects in this array

if (sqlite3_prepare(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {

    while (sqlite3_step(compiledStatement) == SQLITE_ROW) {

        NSMutableArray *tempRowArray=[[NSMutableArray alloc] init];
        [tempRowArray addObject:[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)]];
        [pickerList addObject:tempRowArray];
        [tempRowArray release];
    }
}

picker list is shown as memory leak out there
and application eventually crashes after some time please help me get rid of it

5) I have released pickerList in dealloc() and set it to nil in viewDidUnload

Answer 1

Every time the view appears you allocate pickerList. Allocate it in viewDidLoad and then release it in viewDidUnload.
