是否有一个类/方法来处理拖动视图？
我发现了 有用的教程开始了解 Cocoa 如何处理触摸事件。我使用它作为基础来创建自定义脚本，我试图使 UIView 可拖动，与本机地图应用程序非常相似。
- 我编写了一个自定义脚本，使用 TouchesBegan 方法将会 捕获输入开始的位置并 将其与中心点进行比较 UIView 使用一些条件 声明。
- TouchesMoved 方法会做一些事情 进一步的条件语句 判断是否触摸启动 点和视图的中心将 积极或消极地移动。
- 我也捕捉到了观点 边界，这样就不会走得太远 出去。
它缺乏其他应用程序（例如地图）或滚动 UITable 中的精美外观，例如用户松开手指后的缓动效果，以及到达边界时的可怕的捕捉效果。
有没有一种方法可以像这样获取视图并使其可拖动？如果没有的话我会继续完善我的剧本。
非常感谢！
I found a useful tutorial to get started in understanding how to Cocoa handles touch events. I've used this as a base to create a custom script, I'm trying to make a UIView draggable, very similar to the native Maps application.
- I've written a custom script, using
the touchesBegan method it will
capture where the input began and
compare it to the centre point of the
UIView using some conditional
statements. - The touchesMoved method will do some
further conditional statements to
determine whether the touch start
point and the center of the view will
move positively or negative. - I've also captured the views
boundaries so it doesn't go too far
out.
it's lacking the polished finished found in other applications such as Maps, or scrolling a UITable, such as the ease effect after the user has released their fingers, and the snapping effect when it reaches the boundaries is horrible.
Is there a method that takes a view and makes it draggable like this? If not I'll continue to refine my script.
Many thanks!
