Answer 1

使用UITextInput

的方法时遇到了同样的问题

replaceRange：（UITextRange *）range withText：（NSString *）text;

我无法找到最佳解决方案，但我通过避免使用特殊字符来修复崩溃

在replaceRange方法的第二个参数

ps：此问题仅发生在iOS 11

中

Answer 2

我可以通过一个示例应用程序在iOS 13.0 beta 4中重现它，该示例应用程序显示一个UITextView以及带有链接的特殊属性字符串。点按或拖动链接时会崩溃。

NSMutableAttributedString *aString = [[NSMutableAttributedString alloc] initWithString:@""];

NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = [[UIImage imageNamed:@"weblink"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
attachment.bounds = CGRectMake(0, 0, 15, 15);
[aString appendAttributedString:[NSAttributedString attributedStringWithAttachment:attachment]];

[aString appendAttributedString:[[NSAttributedString alloc] initWithString:@"  More Information"]];
[aString addAttribute:NSLinkAttributeName value:[NSURL URLWithString:@"https://www.apple.com"] range:NSMakeRange(0, aString.length)];

self.textView.attributedText = aString;

在Feedback Assistant上归档为FB6738178。
