从 UITextView 中删除/移除 NSTextAttachment

我有一个UITextView这将有图像的混合（如NSTextAttachment) 和字符串。这UITextView是不可选择的，所以我可以使用：

- (BOOL)textView:(UITextView *)textView shouldInteractWithTextAttachment:(NSTextAttachment *)textAttachment inRange:(NSRange)characterRange 

我该如何删除textAttachment在方法中？

您可以使用replaceCharactersInRange:withString: of NSMutableAttributedString删除附件（您将范围作为参数UITextViewDelegate方法）：

//Retrieve the attributed string
NSMutableAttributedString *mutableAttr = [[textView attributedText] mutableCopy];
//Remove the attachment
[mutableAttr replaceCharactersInRange:range withString:@""]; 
//Set the new attributed string
[textView setAttributedText:mutableAttr];
