Tips for iOS Simulators

1. During Project Creation, IOS simulators often encounter slow operations. For example, if a uialertview pops up and is pushed to a viewcontroller, the process is very slow and the xcode console prints the following sentence:

Simulator slow-motion animations are now on

I thought it was a simulated death. Later I found that this was not the case. I accidentally triggered an action.

Select the IOS simulator, and press the Shift key three times in a row to restore the original speed, and the console output:

Simulator slow-motion animations are now off

In fact, after selecting the IOS simulator, in the menu bar in the upper left corner, "debug" contains an option to "switch to slow Animation". You can also click this option to switch.

2. After selecting the IOS simulator, in the menu bar in the upper left corner, you can select the IOS simulator devices in the "hardware" option, such as the iPad simulator and iPhone 5 simulator, as well as left and right rotation, back to the home page, lock and so on.
