if ([cllocationmanagerlocationservicesenabled]) {

self. Locationmanager = [[cllocationmanageralloc]init];

Self. Locationmanager. delegate =self;

self. Locationmanager . Desiredaccuracy =kcllocationaccuracybest;

self. Locationmanager. Distancefilter =Kdistancefilter;

self. Locationmanager. Headingfilter =Kheadingfilter;

self. Locationmanager . pauseslocationupdatesautomatically =YES;

self. Locationmanager . Activitytype =clactivitytypefitness;

}

Desiredaccuracy: To achieve the positioning accuracy, as far as possible to meet the accuracy of the set, but can not be guaranteed in the actual process to achieve.

Distancefilter: Below the horizontal distance is filtered out without generating an update event.
