我试图使用此代码获取节标题视图:

[tableView headerViewForSection:indexPath.section];

但是这段代码总是让我失败.你能给我一些例子来从表视图中获取节头视图吗？这是我的viewForHeader实现:

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

  DynamicHeader *headerView = [[DynamicHeader alloc] init];
        headerView.frame = CGRectMake(0, 0, 320, 40);
        UILabel *headerLbl = [[UILabel alloc] init];
        headerLbl.frame = CGRectMake(10, 10, 300, 20);
        if(((SectionViewController *)sharedInstance.currentViewController).currentSectionType == 25)
        {
            UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"minus.png"]];
            imgView.frame = CGRectMake(285, 14.5, 16, 13);
            [headerView addSubview:imgView];
            UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:sharedInstance action:@selector(headerTap:)];
            [headerView addGestureRecognizer:recognizer];
            headerView.tableView = tableView;
            headerView.heightForRows = 95;
            headerView.isOpen = YES;
        }
 headerLbl.text = [[[[[((SectionViewController *)sharedInstance.currentViewController).responseDictionary valueForKey:DATA_PARAMETER] valueForKey:SECTION_TABLE_PARAMETER] objectAtIndex:section] …

如何使用SLRequest将UIImage附加到Facebook上的帖子.这是我的代码:

SLRequest *facebookRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                                 requestMethod:SLRequestMethodPOST
                                                                      URL:[NSURL   URLWithString:@"https://graph.facebook.com/me/feed"]
                                                               parameters:[NSDictionary dictionaryWithObject:post forKey:@"message"]];

我知道有必要在参数中指定图片,但我不知道它要做什么.

我正在尝试实现iOS 6日历中的事件表.

我有UITableView 500行(事件).当我开始滚动动画是顺利的.

但是在两百行开始滞后之后.在原生iOS 6日历事件列表中,所有工作都顺利进行

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    double begin = CFAbsoluteTimeGetCurrent();
    if(!self.isNoResults)
    {
        NSString *cellIdentifier = [NSString stringWithFormat: @"Cell %i %i", indexPath.row, indexPath.section];
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
        UIImageView *circleImgView;
        NSString *startTimeStr;
        NSDateFormatter *formatter;
        UILabel *timeLbl;
        UILabel *titleLbl;
        UILabel *endsLbl;
        UIImageView *eventTypeImgView;
        if(cell == nil)
        {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
            circleImgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"newMesIcon.png"]];
            circleImgView.frame = CGRectMake(14, 19, 12, 12);
            [cell.contentView addSubview:circleImgView];



            timeLbl = [[UILabel alloc] init];
            [timeLbl setBackgroundColor:[UIColor clearColor]]; …

我如何在静态方法中设置委托和dataSource .

+(void)method
{
    UITableView *tv = [[UITableView alloc] init];
    tv.delegate = self;   // Warning: incompatible pointer type
    tv.dataSource = self; // Warning: incompatible pointer type
}
