IOS Cllocationmanager Targeting

This article reprinted to Http://www.tuicool.com/articles/7JBRZn

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!

<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=;     [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) { Span class= "indent" >  NSLog (@ "Access Denied"); }  if ([Error Code]==kclerrorlocationunknown) {  NSLog (@ "Cannot get location information"); }}      

Using corelocation positioning in iOS8

1, before the use of corelocation need to call the following function "IOS8 dedicated": iOS8 some changes to the location, including the method of locating authorization, Cllocationmanager added 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=;  if (iosversion>=8) { [Locationmanager requestwheninuseauthorization];  Allow access to location data in the course of the program (iOS8 positioning required) } [Locationmanager startupdatinglocation];  Turn on positioning           

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!
