【问题描述】：

我有一个 UITextView，其中我看不到长按文本放大镜。有没有办法强制那个放大镜出现？

【参考方案1】：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer 

    BOOL isAtLeastOneGestureInlineTextView = [self isInlineTextView:gestureRecognizer.view] || [self isInlineTextView:otherGestureRecognizer.view];
    if ((gestureRecognizer == [self longPressGesture]) && !isAtLeastOneGestureInlineTextView) 
        return NO;
    

    if (gestureRecognizer == [self panGesture]) 
        return NO;
    

    return YES;


- (BOOL)isInlineTextView:(UIView *)view 
    return [view isKindOfClass:[SFGInlineTextView class]];

显然有这个禁用长按的检查。为了保留以前的实现，我检查了手势不是所需的textView。
