This example will show delegate methods for UITableView Controller.
1. This delegate method is used for creating number of sections in UITableView.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {// Return the number of sections.
return 1;
}
2. This delegate method is used for set number of rows in section in UITableView.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {// Return the number of rows in the section.
return 20;
}
3. This delegate method is
used for creating or modifying UITableView cell, this method is also
used for set customized cell for a UITableView.
// Customize the appearance of table view cells.- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UISecondViewTVCell *secondCell = (UISecondViewTVCell *)[tableView dequeueReusableCellWithIdentifier:@"myidentifier"];
if(secondCell == nil){
UIViewController *mycontroller = [[UIViewController alloc]initWithNibName:@"SecondViewTVCell" bundle:nil];
calanderCell = (UISecondViewTVCell *)mycontroller.view;
[mycontroller release];
}
secondCell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return secondCell;
}
4. This delegate method is used for creating customized header for a UITableView.
-(UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
viewHeader.backgroundColor = [UIColor colorWithRed:(112.0/255.0) green:(0.0/255.0) blue:(11.0/255.0) alpha:1.0];
UILabel *lblName = [[UILabel alloc]initWithFrame:CGRectMake(87, 5, 50, 21)];
lblName.backgroundColor = [UIColor clearColor];
lblName.textColor = [UIColor whiteColor];
lblName.text = @"Name";
[self.viewHeader addSubview:lblName];
UILabel *lblDate = [[UILabel alloc]initWithFrame:CGRectMake(241, 5, 50, 21)];
lblDate.backgroundColor = [UIColor clearColor];
lblDate.textColor = [UIColor whiteColor];
lblDate.text = @"Date";
[self.viewHeader addSubview:lblDate];
return viewHeader;
}
5. This delegate method is used for getting the selected row index of UITableView.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {UIViewController *secondView = [[UIViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
[self.navigationController pushViewController:secondView animated:YES];
}
6. This delegate method is used for creating customized header for a UITableView.
-(UIView *) tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{if (tableView.tag == 2) {
UIImageView *imgViewFooter = [[UIImageView alloc] initWithFrame:CGRectMake(0 ,200 , 225, 34)];
imgViewFooter.image = [UIImage imageNamed:@"twitterFooter.png"];
return imgViewFooter;
}
