Question

我制作了一个UIScrollView，我正在添加子视图。

但是当我水平滚动时，它会在scollview上传递一些物体。

我的代码是

#pragma mark - profileDataParsingFinish
-(void)profileDataParsingFinish:(MainUserDAO *)mainUserDAO
{

    NSLog(@"Profile Data Parsing Finish ...  ");

    currentDao=mainUserDAO;

    [headerScroll setContentSize:CGSizeMake(3200.0f, 110.0)];
    NSString *newStr = [mainUserDAO.statusThumb substringWithRange:NSMakeRange(1, [mainUserDAO.statusThumb length]-1)];
    NSURL *imageURL=[[NSURL alloc] initWithString:[NSString stringWithFormat:@"%@%@",serverPart,newStr]];

    if([mainUserDAO.CityName isEqualToString:@"(null)"]){
    }
    else 

    [livesTitle setText:mainUserDAO.CityName];
    [javaTitle setText:mainUserDAO.JobTitle];

    if([currentDao.maritialStatusPrivacyId isEqualToString:@"1"]){
        [maritialIcon setHidden:YES];
        [maritialLabel setHidden:YES];

    }
    else if([currentDao.maritialStatusPrivacyId isEqualToString:@"2"]){
    /*
        <MaritalStatus><MaritalStatusID>1</MaritalStatusID><Title>Single</Title></MaritalStatus><MaritalStatus><MaritalStatusID>2</MaritalStatusID><Title>Engaged</Title></MaritalStatus><MaritalStatus><MaritalStatusID>3</MaritalStatusID><Title>In a relation</Title></MaritalStatus><MaritalStatus><MaritalStatusID>4</MaritalStatusID><Title>Married</Title></MaritalStatus><MaritalStatus><MaritalStatusID>5</MaritalStatusID><Title>Divorced</Title></MaritalStatus><MaritalStatus><MaritalStatusID>6</MaritalStatusID><Title>Widowed</Title></MaritalStatus><MaritalStatus><MaritalStatusID>7</MaritalStatusID><Title>Not interested</Title></MaritalStatus></ArrayOfMaritalStatus>
     */
        if([currentDao.maritialStatusId isEqualToString:@"1"]){
            [maritialLabel setText:@"Single"];
        }
        else
            if([currentDao.maritialStatusId isEqualToString:@"2"]){

    int imagex=650;

        friendThumb.imageView.layer.borderWidth=0.8f;
        friendThumb.imageView.layer.borderColor=[[UIColor whiteColor] CGColor];
        [headerScroll addSubview:friendThumb];


        favTite.center = friendThumb.center;
        CGRect f = favTite.frame;
        f.origin.y = imagey-20; // new y
        favTite.frame = f;



        FavouritImageDownloader *favdownloader=[[FavouritImageDownloader alloc]init];
        [favdownloader startDownloading:currentDao.friendThumb withButton:friendThumb];
        [friendThumb addTarget:self action:@selector(showFriendDetail) forControlEvents:UIControlEventTouchUpInside];
    }

    ...............................// More Code here, I can't paste due to limit of Stack characters

    [self.headerScroll scrollRectToVisible:CGRectMake(321,
                                                      self.headerScroll.frame.origin.y,
                                                      self.headerScroll.frame.size.width,
                                                      self.headerScroll.frame.size.height) animated:YES];
}

当我滚动时，它省略了一些组件。

那么如何才能滚动到特定位置，它必须滚动。

有两种scrollview方法可以帮助您滚动到特定点或框架。

[scrollview scrollRectToVisible:<#CGRect#>YOURRECT animated:YESORNO];

[scrollview setContentOffset:<#(CGPoint)#>YOURPOINT];

希望这有帮助。

UIScrollView向上滚动到特定页面？
