This is not realistic, and I think that the refresh does not "reset" the page duration counter, which I think should happen. I guess this could be done with a hard refresh (Ctrl-F5 in Windows, Option+R in MacOSX), but I don't know if it is

问题 I'm working on an Xcode 7 Playground that has many things running at once. Whenever I make an edit, it refreshes, restarts what was running and runs through the entire code again. That crashes my playground around every 15 minutes. Is there a way to prevent playgrounds from automatically running whenever I make an edit? 回答1: In the lower-left part of the Playground there's a right-facing blue arrow, looking like a "play" button. Do a long click on this button and you will get two options:
