blocks|key|1689120|text|这似乎是iOS+7.0的UITextView中的错误。similar+question有一个似乎有帮助的解决方法:先将文本视图的文本设置为nil，然后再将其设置为新的文本字符串。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1689121|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/18968687/774^0|C|A|1X|3|R|G|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]]|E|$]]|$1|F|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

This appears to be a bug in iOS 7.0's <code>UITextView</code>s. A <a href="https://stackoverflow.com/a/18968687/774">similar question</a> has a workaround which seems to help: set the text view's text to <code>nil</code> before setting it to the new text string.

blocks|key|1902613|text|在一个非常类似的问题中，将文本设置为nil对我不起作用，但将scrollEnabled设置为NO，就像建议的here一样，对我起到了作用。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1902614|编辑:此外，还有一个非常特殊的情况，它导致了问题:当一个框以一个链接开始，并且新文本被设置为空文本(@"“-不是nil!)这个框不知何故被“打破”了，从那时起，任何新的文本都变成了一个链接。我的解决方案是覆盖setText，首先将超级文本设置为@"x“，然后设置为实际的新文本。相反，将其设置为nil也不能解决此问题。|1902615|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/19344607/uitextview-link-detection-working-within-simulator-not-on-device^0|I|3|1A|2|1I|4|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@$9|U|A|V|1|W]]|E|$]]|$1|F|3|G|5|6|7|X|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

Setting the text to <code>nil</code> did not work for me in a very similar problem, but
setting scrollEnabled to <code>NO</code>, like suggested <a href="https://stackoverflow.com/questions/19344607/uitextview-link-detection-working-within-simulator-not-on-device">here</a>, did the trick for me.

Edit:
In addition there was still a very special case, that caused problems: When a box began with a link and the new text was set to empty text (@"" - not nil!) the box somehow "broke" and from then on any new text became a link. My solution was to override setText to set [super text] to @"x" first and then to the actual new text. Setting it to nil instead did not solve this problem either.

blocks|key|1902767|text|将Tint颜色更改为其他颜色实际上是可行的。但是，如果可选择启用，则色调也将是相同的颜色。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1902768|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Changing the Tint color to other color actually works.
However if selectable enable the tint will also be the same color.

blocks|key|1902927|text|建议的变通方法都不适用于我。因此，我决定创建一个新的UITextView，并在每次重用该单元时用旧的替换它。它的性能并不理想，但至少它可以工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1902928|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Non of the suggested workarounds work for me. So I decided to create a new UITextView and replace it with the old one, every time the cell is reused. It is not ideal for performance, but at least it works.

blocks|key|1903118|text|由于上面的任何解决方案对我都有效，我发现的一个变通方法是在应该更新每个单元格的文本时创建UITextView，而不是在可重用的单元格中重用。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1903119|您在UITableViewCellDataSource中的代码为：|1903120|-+(void)updateDescriptionWithText:(NSString+*)descriptionText

As any of the above solutions worked for me, a workaround I've found is to create your <code>UITextView</code> when you are supposed to update the text for each cell instead of reusing in the reusable cell.

Your code in the <code>UITableViewCellDataSource</code> would be :

<pre><code>- (void)updateDescriptionWithText:(NSString *)descriptionText
{
 UITextView *descriptionTV = [[UITextView alloc] initWithFrame:aFrame];
 [descriptionTV setScrollEnabled:NO]; 
 [descriptionTV setEditable:NO]; 
 [descriptionTV setDataDetectorTypes:UIDataDetectorTypeLink]; 
 if ([descriptionV respondsToSelector:@selector(setSelectable:)]) 
 [descriptionTV setSelectable:YES];
 [descriptionTV setText:descriptionText];
 [self addSubview:descriptionTV];
}
</code></pre>

And in the <code>UITableViewCell</code>:

<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 ***your init code***

 [cell updateDescriptionWithText:description];
} 
</code></pre>

Several suggestions here and through links provided did not help me with this bug.

I tried setting attributed text, setting text to nil, setting text to @"".

In the end forcing the text view in an out of editable mode did the trick. In prepare for reuse

<pre><code>- (void)prepareForReuse
{
 ...
 textView.editable = YES;
 textView.editable = NO;
 ...
}
</code></pre>

blocks|key|1903256|text|您可以使用NSAttributedString解决此问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1903257|cell.textview.attributedText+=+[[NSAttributedString+alloc]+initWithString:message.message];|code-block|syntax|javascript|1903258|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can fix this issue by using NSAttributedString.

<pre><code>cell.textview.attributedText = [[NSAttributedString alloc] initWithString:message.message];
</code></pre>

blocks|key|1903378|text|找到了一个更好的方法来解决这个问题。这需要在每次设置文本时执行额外的步骤。但这绝对解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1903379|_textView.selectable+=+NO;+//+set+it+to+NO+clears+all+possible+data+detection+work+so+far.
_textView.selectable+=+YES;+//+set+it+to+YES+so+that+actual+links+are+detected.|code-block|syntax|javascript|1903380|基本上，数据检测需要将selectable字段设置为YES才能工作。当您将其设置为NO时，它将被完全删除。|offset|length|style|CODE|1903381|注意:这只适用于ios7。|1903382|entityMap^0|0|0|B|A|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Found a better way to solve this problem. This requires an extra step every single time you set text. But this definitely fixes the problem. 

<pre><code>_textView.selectable = NO; // set it to NO clears all possible data detection work so far.
_textView.selectable = YES; // set it to YES so that actual links are detected.
</code></pre>

Basically data detection requires the <code>selectable</code> field to be set to YES to work. When you set it to NO, its completely removed.

Note: This is only for ios7.

blocks|key|1903489|text|这些答案对我都不起作用(iOS8，Swift)，唯一对我起作用的是首先将文本设置为nil，然后在新文本前面加上一个不可见的空白unicode字符(我选择了\u200B，它是零宽度空格字符，但任何字符都可以)：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1903490|textView.text+=+nil

None of these answers worked for me (iOS8, Swift), the only thing that worked for me was to first set the text to <code>nil</code> and then prepend the new text with a non-visibile whitespace unicode character (I chose <code>\u200B</code>, which is the ZERO WIDTH SPACE character but any character works):

<pre><code>textView.text = nil
textView.text = "​\u{200B}\(newText)"
</code></pre>

blocks|key|1903560|text|这个对我来说是可靠的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1903561|//+fix+url+detection+bug

cell.textView.dataDetectorTypes = UIDataDetectorTypeLink;

blocks|key|1903675|text|我也面临着这个问题，我发现解决这个问题的方法是按以下顺序设置textview属性，|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1903676|[textview+setDataDetectorTypes:UIDataDetectorTypeNone+];

[textView+setDataDetectorTypes:UIDataDetectorTypeLink];

I also face this problem and I found out to solve this is to set textview properties in the following order,

<pre><code>[textview setDataDetectorTypes:UIDataDetectorTypeNone ];
textView.editable = NO;
[textView setDataDetectorTypes:UIDataDetectorTypeLink];
textView.text=@"The text you need to show with link";
</code></pre>

Hope this help you.....

I have custom UITableViewCells that contain a UITextView. I have link detection in the UITextView turned on in Interface Builder. When I first load the table view, everything seems to be working, but as I scroll up and down the table view, the link detection gets messed up. Specifically, cells that just have regular text (which are presented normally initially) are being shown as links (all the text in the text view is coloured blue and is an active link), and the links point to objects that are in some of the other table view cells. For example a link might point to a website that was in a different table view cell, or launch an email to an address that was in a different table view cell.

It seems like when the table view cells are being reused, even though the text view text is being updated, the links are somehow getting saved.

This only happens in iOS 7, not iOS 6. It happens in the simulator and on my device.

Here is the code:

<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 NSString *sectionKey = [self.orderedSectionKeys objectAtIndex:indexPath.section];
 NSDictionary *infoDictionary = [[self.tableViewData objectForKey:sectionKey] objectAtIndex:indexPath.row];

 static NSString *cellIdentifier = @"InfoDefaultTableViewCell";
 InfoDefaultTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
 if (cell == nil) { 
 NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"InfoTableViewCells" owner:self options:nil];
 cell = [topLevelObjects objectAtIndex:0];
 }

 cell.bodyTextView.text = [infoDictionary objectForKey:@"description"];

 return cell;
}
</code></pre>

Does anyone know what is happening here, and how to solve it?

<hr>

I tried adding this code after setting the text view text, to try to reset the links:

<pre><code>cell.bodyTextView.dataDetectorTypes = UIDataDetectorTypeNone;
cell.bodyTextView.dataDetectorTypes = UIDataDetectorTypeAddress | UIDataDetectorTypeLink | UIDataDetectorTypePhoneNumber;
</code></pre>

but it didn't change the behaviour that I'm seeing.
