UITextView实现只允许链接交互不允许选择图片的方
检测链接
大家都知道,UITextVview可以用以下方法自动检测text中的链接:
let label = UITextView() label.dataDetectorTypes = .link label.isEditable = false
如果我们使用的attributedString后,会发现如果添加Attachment后,会触发一个选择(编辑的GR),如果我们只想要链接的gr,不想要选择的gr,可以遍历并禁用它。方法如下:

Objective-C
NSArray *textViewGestureRecognizers = self.captionTextView.gestureRecognizers; NSMutableArray *mutableArrayOfGestureRecognizers = [[NSMutableArray alloc] init]; for (UIGestureRecognizer *gestureRecognizer in textViewGestureRecognizers) { if (![gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) { [mutableArrayOfGestureRecognizers addObject:gestureRecognizer]; } else { UILongPressGestureRecognizer *longPressGestureRecognizer = (UILongPressGestureRecognizer *)gestureRecognizer; if (longPressGestureRecognizer.minimumPressDuration < 0.3) { [mutableArrayOfGestureRecognizers addObject:gestureRecognizer]; } } } self.captionTextView.gestureRecognizers = mutableArrayOfGestureRecognizers;
