How to set Apple's 6Plus mobile phone into categories such as photography, food, shopping and tools?

For the 3D Touch function, of course, your own application must be the first to support this function. As long as you press the application icon on the screen hard, you can see additional function options, just like the option function of right-clicking the computer.

It is worth noting that when I first got the iPhone6S, I was used to tapping the screen, so pressure sensing may take a little time to get used to it. If there is no pop-up function option after pressing the icon on the screen, it means that the pressing force is not enough.

Of course, for 3D Touch on iPhone6S, there are setting options in the system. You can open the settings application on the iPhone first. Next, in the settings list, click the General bar. In the general list, locate the accessibility column, and then click Enter. Then in the auxiliary function, click the option in the column of 3D Touch to see its setting interface. Here you can see that there is a setting option for 3D touch sensitivity, which has three levels: weak, medium and strong.

At this time, you can find the appropriate pressing force according to the pictures provided below. Everyone has different degrees of light and heavy pressing, and its sensitivity can be adjusted here.
