在UITextView中成功滑动？ [英] Successful Swipe in UITextView?

问题描述

有没有人能够在UITableView上实现成功的滑动手势？默认情况下，由于控件的滚动特性，这是不可能的。我已经尝试了子类化UITextView并在实例方法中实现了滑动功能，但没有骰子。

Has anyone been able to implement a successful swipe gesture on a UITableView? By default this is not possible due to the scrolling nature of the control. I've tried subclassing UITextView and implementing the swipe function in the instance methods, but no dice.

我的UITextView已禁用滚动 - 除非有另一种方法来实现多行文本？

My UITextView has scrolling disabled - Unless there is another way to implement multiline text?

我应该说的是输入多行文字[/编辑]

What I should say is input multiline text[/Edit]

推荐答案

我发现，更好的解决方案是简单地将触摸传递回superview：

An even better solution, I have found, is to simply pass touches back to the superview:

@interface SwipeableTextView : UITextView {
}

@end

@implementation SwipeableTextView

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];

    [self.superview touchesBegan:touches withEvent:event];

}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesMoved:touches withEvent:event];

    [self.superview touchesMoved:touches withEvent:event];
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesEnded:touches withEvent:event];

    [self.superview touchesEnded:touches withEvent:event];
} 

@end
