A while ago I was experimenting, trying to see if i could get navigation items to animate and scroll between each other.
I don't know if this is related but suddenly without touching the simulator options I'm getting this message Simulator slow-motion animations are now on and moving between views is very slow, like 3 seconds. This occurs with all animation effects.
Any idea what I need to do to stop this ?
The shortcut as of Xcode 6 is Command ⌘+T. This toggles it between on and off, so to turn it off just punch that combination.
Just figured this out:
You can toggle slow-motion animations on and off by pressing Shift three times in succession while the iOS Simulator is in focus.
because there's no home button in the iPad simulator since iOS 5.0, we need a key combination (shift+command+h), which may activate slow motion. This glitch keeps happening to me, and quite annoying.
In the simulator at the top bar, go to Debug
Slow Animations and check it off or on.
Nothing to it.
I ran into this same problem, and it seems that now the shortcut is ⌘+T to toggle it on any app that you're running. If you're on the home screen it should toggle all of the base OS animation speeds.
One reason this keeps happening to me is I use a VNC viewer to remotely work on my Mac mini, and it defaults to sending repeated keypresses whenever any key (including shift) is held down.
So even though "I" am not pressing shift multiple times, if I use the physical keyboard to enter text, then just holding shift down long enough to type a few letters results in the Mac seeing it multiple times and toggling the slow animations.
One work around is to not use the physical keyboard, but instead always "type" using the mouse to select letters on the simulators pop-up keyboard.
When simulator is open, simulator window show 6 commands including file, edit, hardware, debug, window and help.
Just click on Debug and the first position is stop animation window + T command is use for it.
If the slow animation is checked then simply unchecked it.
I couldn't fix it with triple shift, or triple home.
Could not fix via Debug->Toggle Slow Animation either.
Instead, you can reset the whole damn thing: iOS Simulator -> Reset Content and Settings.
Note that I had 2 problems.. slow motion inside the app (which was toggled by the debug->toggle menu) and slow motion when I switch between apps, aka "everything". I was only able to fix the global slow mo by resetting.
On 5.1 it can be toggled by hitting Shift twice, just like we do double-click on mouse.
