I've seen this too on iOS mostly when dealing with the main queue and displaying alerts using a GDC dispatch
In addition to that, I've also see this one that's really odd. It can take about 10 - 15 seconds before the keyboard displays in the following case:
- Run your iOS app from Xcode on an iPad plugged in to your Mac.
- In your first UIViewController have an editable UITextField and make it become the firstResponser on the VDL, VWA or VDA.
- Log when your call to makeFirstResponder is issued.
- Log when the keyboard appears on the screen.
Only when the iPad is plugged in your Mac that is running Xcode and when the app is launched from Xcode does this delay happen.
If you launch an app of this type from outside Xcode, directly off the device, the delay doesn't happen.
I thought I was the only one who ran into this and then found it mentioned on stackOverflow that it's a known problem.
