执行双指旋转的图像的最小尺寸是多少
我目前正在尝试在尺寸为 155*75 的图像上执行双指旋转并且其工作正常，但是当我尝试在 45*25 的图像上执行相同的操作时，它不起作用。所以我认为问题可能是由于小尺寸和宽度 那么图像要执行平滑的双指旋转的最小尺寸是多少呢？
I am currently try to perform double finger rotation on a image of size 155*75 and its working properly but when i try to perform the same operation on a image 45*25 its not working.So i think the problem may be due to small size and width So what is the minimum size for an image to perform smooth double finger rotation?

Apple 建议 iOS 设备屏幕上的手指宽度约为 44 点。基于此，要容纳其中两个，您需要 88 分。我会说88x88。
Apple suggest that a finger is approximately 44 points wide on an iOS device screen. Based on that, to fit two of them you'd need 88 points. I'd say 88x88.
是的，我同意Amorya。几个月前，我构建了一个带有多个按钮的应用程序，并且按钮的大小小于 30px。它变得很难触摸。
Yes, I'm agree with Amorya. Few month ago, I've build an app with several button and the buttons size were less than 30px. It became difficult to touch.
