ScrollView setcontentoffset问题

Question

我正在添加页面（视图）以滚动视图，而视图在屏幕外像这样

-(void)loadScrollView:(NSInteger)CurrentPage
{
    int pageNo=objGameData.CurrentPageNo-1;
    [self.EDDescriptionScrollView setContentOffset:CGPointMake((pageNo*EDDescriptionScrollView.frame.size.width)+80, EDDescriptionScrollView.frame.size.height)];

    self.EDDescriptionScrollView.contentSize=CGSizeMake(EDDescriptionScrollView.frame.size.width*objGameData.CurrentPageNo,EDDescriptionScrollView.frame.size.height);




    edView=[[EDView alloc]initWithFrame:CGRectMake((CurrentPage-1)*EDDescriptionScrollView.frame.size.width, 0, EDDescriptionScrollView.frame.size.width, EDDescriptionScrollView.frame.size.height)];

    [edView.EDMsgTextView setText:[NSString stringWithFormat:@"%@",[self.EDDescrptionArray objectAtIndex:(CurrentPage-1)]]];
    edView.EDMsgTextView.delegate=self;
    edView.backgroundColor=[UIColor clearColor];
    edView.CorrectWordLbl.text=self.CurrentWord;
    edView.TotalPointsLost.text=[NSString stringWithFormat:@"Points : %d",objGameData.CurrentPointsLostEarned];
    edView.tag=pageNo;
    [self.EDDescriptionScrollView addSubview:edView];
}

现在，当我在屏幕上移动EDDescriptionScrollView的超级视图并想要跳转到除最后一个页面之外的某个页面时，我只是做了

 [self.EDDescriptionScrollView setContentOffset:CGPointMake((pageNo*EDDescriptionScrollView.frame.size.width)+80, EDDescriptionScrollView.frame.size.height)];

将滚动视图带到页面但内容仅在我触摸屏幕时显示。 我正在做的任何事都是错的？ 我也试过调用layoutsubview，问题仍然存在。

Answer 1

尝试拨打[self.EDDescriptionScrollView layoutIfNeeded]

Answer 2

[self.EDDescriptionScrollView setContentOffset:CGPointMake((pageNo*EDDescriptionScrollView.frame.size.width)+80, EDDescriptionScrollView.frame.size.height)]; “pageNo”应为“pageNo - 1”
