How to scroll in iOS Simulator on mac book air?

问题:

I have a scroll view and and an embed UIImageView. Code is right but I can not scroll in the Simulator likely because I have a trackpad, not a mouse. Or can I?

回答1:

You can click the trackpad and drag (as other folks have said), or if you have "Three finger drag" enabled in Trackpad preferences, you can scroll with three fingers.

Here's a guide to all of the gestures in the simulator: iOS Simulator User Guide

You need to enable 3 finger drag:

1. From the Apple menu, choose System Preferences.
2. Click the Accessibility icon
3. Choose Mouse & Trackpad from the options on the left
4. Click Trackpad Options
5. Place a checkmark next to "Enable dragging"
6. From the related pop-up menu, choose “three finger drag” so there's a checkmark next to it
7. Click OK
