Xcode 将UIView更改为UIScrollView后，触摸移动不再触发？

我有一个有很多东西的UIView。我还有一个触摸屏的实现，如下所示：

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"move");
}

#import "AppScrollView.h"

@implementation AppScrollView

- (id)initWithFrame:(CGRect)frame
{
    return [super initWithFrame:frame];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AppScrollView touchesEnded:withEvent:");

    // If not dragging, send event to next responder
    if (!self.dragging)
        [[self.nextResponder nextResponder] touchesEnded:touches withEvent:event];
    else
        [super touchesEnded: touches withEvent: event];

}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AppScrollView touchesMoved:withEvent:");

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

@end

我最近想让视图滚动，所以我只是打开UIView，在Interface Builder中将其对象类更改为UIScrollView。但是，现在，即使我触摸屏幕，也不会调用“touchesMoved”方法

有人能帮我重新开始工作吗？我不知道我是怎么打破它的

编辑：我试着跟随，但我可能做错了什么。从阅读其他帖子来看，UIScrollView似乎无法接受触摸事件本身，它们需要发送到响应者链上？我将非常感谢任何能帮助我解决这个问题的人。。。当我意识到UIScrolView扼杀了我的触摸检测时，我的应用程序正准备提交！（我刚刚将我的应用程序UIView更改为UIScrollView，以允许与iPhone 4兼容）。

我刚刚查看了您的编辑，我想我可以看到问题所在。关于类似的问题，请参见

您的

UIScrollView

子类将如下所示：

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"move");
}

#import "AppScrollView.h"

@implementation AppScrollView

- (id)initWithFrame:(CGRect)frame
{
    return [super initWithFrame:frame];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AppScrollView touchesEnded:withEvent:");

    // If not dragging, send event to next responder
    if (!self.dragging)
        [[self.nextResponder nextResponder] touchesEnded:touches withEvent:event];
    else
        [super touchesEnded: touches withEvent: event];

}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AppScrollView touchesMoved:withEvent:");

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

@end

2013-06-11 10:45:21.625 Test[54090:c07] AppScrollView touchesMoved:withEvent:
2013-06-11 10:45:21.625 Test[54090:c07] SomeClass touchesMoved:withEvent:
2013-06-11 10:45:21.642 Test[54090:c07] AppScrollView touchesMoved:withEvent:
2013-06-11 10:45:21.642 Test[54090:c07] SomeClass touchesMoved:withEvent:
2013-06-11 10:45:21.655 Test[54090:c07] AppScrollView touchesEnded:withEvent:
2013-06-11 10:45:21.656 Test[54090:c07] SomeClass touchesEnded:withEvent:

包含

AppScrollView

对象的类应采用

UIScrollViewDelegate

协议并实现以下方法：

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"SomeClass touchesMoved:withEvent:");
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"SomeClass touchesEnded:withEvent:");
}

然后，记录的输出将如下所示：

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"move");
}

#import "AppScrollView.h"

@implementation AppScrollView

- (id)initWithFrame:(CGRect)frame
{
    return [super initWithFrame:frame];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AppScrollView touchesEnded:withEvent:");

    // If not dragging, send event to next responder
    if (!self.dragging)
        [[self.nextResponder nextResponder] touchesEnded:touches withEvent:event];
    else
        [super touchesEnded: touches withEvent: event];

}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AppScrollView touchesMoved:withEvent:");

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

@end

你的问题看起来很像。也许其中一个建议对你有用？谢谢你的链接。他们建议设置mainScroller.delaysContentTouches=NO；和_mainScroller.canCancelContentTouches=NO；我已经做了这两件事，我的触摸仍然没有被检测到。非常感谢你的回复。。。今天下班后我会试试看，然后回来汇报！嗯。它起作用了。虽然只有一个nextResponder调用，但它不起作用。知道为什么吗？
