Question

我有一个控制器视图，包括（图像和文本）。

这两个组件位于UIScrollView，图像为UIImageView，文本为UITextView（已启用滚动）。当我试图滚动整个屏幕时，文本不会随之滚动，因为它有自己的滚动。

我需要的是用整个屏幕滚动条滚动文本。（将文本的滚动条与整个滚动条合并）。

我应该将文本类型更改为标签而不是textview，或者我该怎么做？

谢谢，

Answer 1

使用此方法：

- (void)textViewDidBeginEditing:(UITextView *)textView
{
    if(textView==your_textview)
    {
        [yourscroolview setContentOffset:CGPointMake(0,textView.center.y-180) animated:YES];
    }


}
- (void)textViewDidEndEditing:(UITextView *)textView
{
    [yourscroolview resignFirstResponder];
    [yourscroolview setContentOffset:CGPointMake(0,0) animated:YES];

}

只需在viewWillAppear:方法中添加此代码即可在加载时指定UITextView的文字。

yourTextView.frame = CGRectMake(yourTextView.frame.origin.x, yourTextView.frame.origin.y, yourTextView.frame.size.width, yourTextView.contentSize.height);
yourTextView.text=@"Your Text";
float fscrview = yourTextView.frame.origin.y + yourTextView.frame.size.height + 20;
yourScrollView.contentSize=CGSizeMake(320, fscrview);

对于前。

yourTextView.delegate = self;
yourTextView.userInteractionEnabled = NO;
yourTextView.backgroundColor = [UIColor clearColor];
yourTextView.font = [UIFont fontWithName:@"Helvetica" size:12.0];
yourTextView.textColor = [UIColor whiteColor];
yourTextView.text = @"Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.<br />\r\nLorem ipsum dolor sit amet, consetetur sadipscing elitr.<br />\r\nLorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr. Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.<br />\r\nLorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr. Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.Lorem ipsum dolor sit amet, consetetur sadipscing elitr.";
yourTextView.frame = CGRectMake(yourTextView.frame.origin.x, yourTextView.frame.origin.y, yourTextView.frame.size.width, yourTextView.contentSize.height);
float fscrview = yourTextView.frame.origin.y + yourTextView.frame.size.height + 20;
yourScrollView.contentSize=CGSizeMake(320, fscrview);
