the terminal give me following messages:

your code looks fine. ensure locationmanager retained/strongly-held.

test region code using iphone simulator. on 'debug' menu chose location 'location' submenu. changing different locations exercise code.

i tested code using iphone simulator , choosing locations submenu. entered code's lat/long numbers 'custom location'. here output:

2013-05-15 07:42:50.885 location[69277:c07] {(     (identifier home) <+37.26917400,-119.30660700> radius 100.00m )} 2013-05-15 07:42:50.932 location[69277:c07] started monitoring test region 2013-05-15 07:44:01.103 location[69277:c07] entered region - test 2013-05-15 07:44:59.573 location[69277:c07] entered region - test 

the 'entered region' output occurred when chose 'custom location'. changes made code were: 1) commented out 'mapview' lines , 2) declared viewcontroller interface shown below. had used class extension.

@interface viewcontroller : uiviewcontroller   <cllocationmanagerdelegate>  {   cllocationmanager *locationmanager;   clregion *testregion; } @end 

ensure location services enabled app.
