iPad app running in simulator using more than 100% of CPU?

I am running my app inside the simulator and when I initially run it and debug it etc there is no problem.

The concern comes when I leave it running in the simulator then I open the activity monitor and notice that the app is using about 104% of the CPU

Anyone have any ideas?

EDIT: This causes the fan to run FULL blast all the time until I quit my app.

Hardware Overview:

Model Name: MacBook Pro Model Identifier: MacBookPro6,2 Processor Name: Intel Core i7 P开发者_如何学运维rocessor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 8 GB

Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Serial Motion Sensor: State: Enabled

I think it's because your CPU is dual-core(probably quad-core or more). Which means full use of one core is 100%, and full use of both cores is 200%, etc. This happens in other applications as well.

I had a similar problem. The backboardd process was using > 80% CPU.

I had deleted an app in the iOS simulator and had left all the icons 'jiggling'. I simply 'pressed' the home button (⇧⌘H) in the simulator to stop the icons 'jiggling'.

The backboardd process then went back to nearly 0% CPU.
