如何修改tableview的group name

在tableview的datasource區段加入下面方法

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { NSString *sectionName;
switch (section) {
case 0: sectionName = NSLocalizedString(@"mySectionName", @"mySectionName");
break;
case 1: sectionName = NSLocalizedString(@"myOtherSectionName", @"myOtherSectionName"); break;
// ... default: sectionName = @"";
break; }
return sectionName;
}

另一種可以插入Label
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
//UIImage *myImage = [UIImage imageNamed:@"BUTTON.png"];
NSString *sectionName = nil;
switch (section) {
case 0: sectionName = [NSString stringWithFormat:@"Header Text 1"];
break;
case 1: sectionName = [NSString stringWithFormat:@"Header Text 2"];
break;
case 2: sectionName = [NSString stringWithFormat:@"Header Text 3"];
break;
}
UILabel *sectionHeader = [[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 40)] autorelease];
sectionHeader.backgroundColor = [UIColor clearColor];
sectionHeader.font = [UIFont boldSystemFontOfSize:18];
sectionHeader.textColor = [UIColor whiteColor];
sectionHeader.text = sectionName;
return sectionHeader;
}

如果上第二種方法，那要加入下面方法來控制section header的高度
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
if (section ==0) return 80.0f;
else
return 30.0f;
}
That's because the UITableView automatically sets the frame of the header view you provide to (0, y, table view width, header view height) y is the computed position of the view and header view height is the value returned by tableView:heightForHeaderInSection:
