在UIScrollView中滾動文本

Question

我有一個控制器視圖，其中包括（圖像和文本）。

這兩個組件位於UIScrollView ，圖像為UIImageView ，文本為UITextView （已啟用滾動）。 當我嘗試滾動整個屏幕時，文本不會隨之滾動，因為它具有自己的滾動。

我需要的是使用整個屏幕滾動條滾動文本。 （將文本的滾動與整個文本的滾動合並）。

我應該將文本的類型更改為label而不是textview還是要怎么做？

謝謝，

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];

}

如果在加載時分配了UITextView文本，則只需在viewWillAppear:方法中添加此代碼。

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);

對於前

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.

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);
