IOS Cllocationmanager Targeting

In previous versions of IOS8, we had no problem using cllocationmanager positioning, and recently in the IOS8 system it was not possible to locate .... This is a big problem!

1, first define a global variable to record Cllocationmanager object, introduce corelocation.framework use #import <CoreLocation/CoreLocation.h>

@property (nonatomic, strong) Cllocationmanager  *locationmanager;

2. Initialize the Cllocationmanager and start positioning

Locationmanager=[[cllocationmanager alloc] init];    locationmanager.delegate=self;    Locationmanager.desiredaccuracy=kcllocationaccuracybest;    locationmanager.distancefilter=10;     [Locationmanager startupdatinglocation];//open position

3, the implementation of Cllocationmanagerdelegate agent method

#pragma Mark Cllocationmanagerdelegate
/**
* Get latitude and longitude
*/-(void) Locationmanager: (Cllocationmanager *) Manager didupdatelocations: (Nsarray *) locations{    cllocation * Currlocation=[locations Lastobject];    Location.strlatitude=[nsstring stringwithformat:@ "%f", currLocation.coordinate.latitude];    Location.strlongitude=[nsstring stringwithformat:@ "%f", currLocation.coordinate.longitude];    NSLog (@ "La---%f, lo---%f", currlocation.coordinate.latitude,currlocation.coordinate.longitude);} /** * location failed, callback this method */-(void) Locationmanager: (Cllocationmanager *) Manager didfailwitherror: (nserror *) error{    if ([ Error code]==kclerrordenied) {        NSLog (@ "Access Denied");    }    if ([Error Code]==kclerrorlocationunknown) {        NSLog (@ "Cannot get location information");}    }

Using corelocation positioning in iOS8

1, before using corelocation need to call the following function "IOS8 dedicated":
IOS8 has made some modifications to the positioning, including the method of locating authorization, Cllocationmanager adds the following two methods:
(1) Always allow access to location information

-(void) requestalwaysauthorization;

(2) Allow access to location data during use of the application

-(void) requestwheninuseauthorization;

   Examples are as follows:

Locationmanager=[[cllocationmanager alloc] init];    locationmanager.delegate=self;    Locationmanager.desiredaccuracy=kcllocationaccuracybest;    locationmanager.distancefilter=10;    if (iosversion>=8) {        [Locationmanager requestwheninuseauthorization];//allows access to location data in the course of the program (IOS8 location required)    }    [Locationmanager startupdatinglocation];//open position

2. Add the following configuration in the Info.plist file:
(1) nslocationalwaysusagedescription
(2) Nslocationwheninuseusagedescription

After this is added, the positioning function will be able to use the normal!
