UIViewController不响应触摸 [英] UIViewController not responding to touches

问题描述

嘿，我完全被这个iPhone问题困扰住了.

Hey all, I'm completely stumped with this iPhone problem.

这是我第一次以编程方式构建视图，没有任何笔尖.我可以使视图显示的一切都很好，但是该织补ViewController并没有像我在使用笔尖的程序中那样响应触摸.我应该补充一点，过去我是从基于视图的应用程序模板开始的，而这次我使用的是基于窗口的应用程序模板.

This is my first time building a view programmatically, without a nib. I can get the view displaying things just fine, but the darn ViewController isn't responding to touches the way it used to in programs where I used a nib. I should add that in the past, I started with the View-Based Application template, and this time I used the Window-Based Application template.

我的想法是，基于视图的模板具有神奇的作用，可以使iPhone知道将触摸事件发送到哪里，但是即使经过数小时的Google讨论，我也无法弄清楚那是什么.否则我可能会在一个完全错误的地方寻找东西，而我的麻烦完全与其他事情有关.有什么想法吗?

My thinking is that the View-Based template does something magical to let the iPhone know where to send the touch events, but I can't figure out what that would be even after several hours of bumbling around Google. Or I could be looking in an entirely wrong place and my troubles are related to something else entirely. Any thoughts?

推荐答案

基于视图的模板中没有神奇的东西.无法响应触摸的最可能原因是:

There's nothing magical in the view-based template. The most likely reasons for failure to respond to touches are:

• 您已经弄乱了 touchesBegan:withEvent:， userInteractionEnabled ， exclusiveTouch 或其他东西，以为您需要弄乱这些(通常您不会；默认设置通常是正确的)

• You've messed with touchesBegan:withEvent:, userInteractionEnabled, exclusiveTouch or something else, thinking you need to mess with these (generally you don't; the defaults are generally correct)

您创建了第二个UIWindow

You created a second UIWindow

您在视图上放置了一些内容(即使它是透明的)

You put something over the view (even if it's transparent)

将您的代码简化为仅以编程方式创建一个对触摸做出响应的视图，而没有其他任何事情.它应该只是几行代码.如果您无法正常工作，请发布代码，然后我们会看看发生了什么.

Simplify your code down to just creating a view programatically that responds to a touch and nothing else. It should be just a few lines of code. If you can't get that working, post the code and we'll look at what's going on.
