不知道你做错了什么,但这里是一些示例代码,可以帮助(从post上我的博客):
#define SectionHeaderHeight 40
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
if ([self tableView:tableView titleForHeaderInSection:section] != nil) {
return SectionHeaderHeight;
}
else {
// If no section header title, no section header needed
return 0;
}
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
NSString *sectionTitle = [self tableView:tableView titleForHeaderInSection:section];
if (sectionTitle == nil) {
return nil;
}
// Create label with section title
UILabel *label = [[[UILabel alloc] init] autorelease];
label.frame = CGRectMake(20, 6, 300, 30);
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor colorWithHue:(136.0/360.0) // Slightly bluish green
saturation:1.0
brightness:0.60
alpha:1.0];
label.shadowColor = [UIColor whiteColor];
label.shadowOffset = CGSizeMake(0.0, 1.0);
label.font = [UIFont boldSystemFontOfSize:16];
label.text = sectionTitle;
// Create header view and add label as a subview
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, SectionHeaderHeight)];
[view autorelease];
[view addSubview:label];
return view;
}
这不起作用,因为您还没有初始化标签。你需要`[[UILabel alloc] initWithFrame:someFrame]`。然后,你可以设置它的`text`属性。 – 2009-12-13 19:58:22
