IOS UIS滚动视图不允许在触摸屏幕时关闭键盘

Question

我构建了一个应用程序，当填充文本视图时，键盘会弹出并允许您键入。如果我决定不想让键盘向上，我可以点击背景视图控制器，它就会掉下来。现在，我添加了一个滚动视图。一切都很好，但当我在文本视图外触摸时，我无法进行连接并使键盘脱落。（我无法在Xcode中制作自定义视图控制器）

有人有什么修复方法吗？

提前谢谢！

尝试UITapGestureRecognizer:

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapScrollView:)];
[scrollView addGestureRecognizer:singleTap];

行动：

- (void)tapScrollView:(UITapGestureRecognizer *)gesture { 
    [self.actionField resignFirstResponder];
    [self.impactField resignFirstResponder];
    [self.resultField resignFirstResponder];
}
