iPhone Crash Log: Failed to Resume in Time

Question

I am looking at my crash logs and noticed "failed to resume in time"

Application Specific Information:
com.myApp.MyApp failed to resume in time 
elapsed total CPU time (seconds): 0.680 (user 0.350, system 0.330), 7% CPU 
elapsed application CPU time (seconds): 0.130, 1% CPU

How can I resume in time?

Answer 1

I think that error means that you're doing something on the main thread that takes too long. The phone becomes unresponsive and the OS kills your app.

Try to use asynchronous APIs if possible, or run the long-running task in a background thread.
