TableView titleForHeaderInSection

Question

我的应用程序在4.3.1模拟器和5.0模拟器中显示了这一点.

这是代码:

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
   return @""; 
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    return [[Singleton sharedInstance] getTitleSectionView:segmentedControl.selectedSegmentIndex inDay:section];
}
-(UIView *)getTitleSectionView:(int)week inDay:(int)day;
{
UILabel *lab=[[[UILabel alloc]init]autorelease];
lab.frame=CGRectMake(5, 0,320,20);
lab.text=[[Singleton sharedInstance] getTitleSection:week inDay:day];
lab.backgroundColor=[UIColor clearColor];
lab.textColor=[UIColor whiteColor];
lab.font = [UIFont fontWithName:@"Arial" size:14];

UIImageView * imv = [[[UIImageView alloc]initWithFrame:CGRectMake(0,0, 320, 20)]autorelease];
imv.image=[UIImage imageNamed:@"section-header-bg.png"];

UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)]autorelease];
[view addSubview:imv];
[view addSubview:lab];

    Week *currentWeek = nil;
    if(week)    
        currentWeek = nechetNedel;
    else        
        currentWeek = chetNedel;

    NSMutableArray *dayArray = [currentWeek.days objectAtIndex:day];
    if([dayArray count] >0)
        return view;
    return nil;
}

可能是什么问题,为什么5.0节模拟器中出现了多行？我试图删除该方法,- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section但它没有帮助.我删除了这个方法(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section,线条消失了

Answer 1

您应该为空部分返回nil

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section;

和

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section;

应该返回0

然后它会工作.它是iOS 5.x问题(或功能)
