while (sqlite3_step(statement) == SQLITE_ROW) {
    NSString* delID = [NSString stringWithUTF8String:(const char *) sqlite3_column_text(statement, 0)];
    NSString* name =[NSString stringWithUTF8String:(const char *) sqlite3_column_text(statement, 1)]; 


    NSMutableDictionary *dict=[NSMutableDictionary dictionary];
    [dict setObject:delID forKey:@"delID"];
    [dict setObject:name forKey:@"name"];
    [self.arr addObject:dict];

It never crash for first row but on second row indexPath.row==1 it always crash please see the screen shot below. Thanks for help

Here is I am filling self.arr again

if ([datePicker1.CurrentDate length]) {

UIButton *btn=(UIButton*)[self.view viewWithTag:btnTag];
[btn setTitle:datePicker1.CurrentDate forState:UIControlStateNormal];
}

if ([self.searchDel.arrSelectDelAdd count ]) 
{
    [self.arr addObject:self.searchDel.arrSelectDelAdd];



    [self.tblDelivery reloadData];

}

}

Sorry to bother all of you Actually the problem is that I am adding second or another object like

[self.arr addObject:self.searchDel.arrSelectDelAdd]; //Incorrect, that is adding NSArray type not dictionary

then getting values in cellForRowAtIndexPath

NSDictionary *dict=[arr objectAtIndex:indexPath.row];//here dict will contain NSSArray type not dict type object its causing to crash app.

cell.lblID.text=(NSString*)[dict objectForKey:@"delID"];// at this line.
cell.lblName.text=(NSString*)[dict objectForKey:@"name"];


[self.arr addObjectsFromArray:self.searchDel.arrSelectDelAdd]; // correct, thats the solution giving contents of NSSArray and now working my code
