UITextView文本内容不是从顶部开始 [英] UITextView text content doesn't start from the top

问题描述

我的JSON文件中有一个长文本，但是当我单击UITableViewCell中的链接转到我的UIViewController页面时，UITextView文本会加载字符串内容，但不会从头开始显示内容，因此我必须一直向上滚动.

I have a long text coming from my JSON file but when I click the link from my UITableViewCell to go to my UIViewController page, the UITextView text loads the string content but it does not show the content from the beginning and I have to scroll up all the time.

我需要做什么?

推荐答案

我遇到了同样的问题，结果我不得不在viewDidLayoutSubviews中设置内容偏移才能生效.我正在使用此代码显示归因于静态的文本.

I had the same problem, and turns out I had to set the content offset in viewDidLayoutSubviews for it to take effect. I'm using this code to display attributed static text.

- (void)viewDidLayoutSubviews {
    [self.yourTextView setContentOffset:CGPointZero animated:NO];
}

SWIFT 3:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    self.textView.setContentOffset(CGPoint.zero, animated: false)
}
