objective c - Xcode Instruments shows my main.m file is using 80% of running time -

i started using instruments in xcode. tried tutorials , great. having problem main.m file , can't solve it. run time profiler , shows main.m file using 82% of running time? when click check going on there statement colored reddish , marked 100%:

homecoming uiapplicationmain(argc, argv, nil, nsstringfromclass([uvodappdelegate class]));

i post pic, don't have plenty reputation.

anyone idea?

judging images provided, normal have high cpu utilization in main line.

this line creates application object singleton , starts main event loop.

if in application implement illustration compute intensive function show in profiler stats.
