iOS8 positioning problems (recommended for Cllocationmanager and Mkmapview use)

1. add key nslocationwheninuseusagedescription in Info.plist, nslocationalwaysusagedescription.

2.CLLocationManager Remember to define a member variable, or attribute, otherwise cause the system prompt to open the position prompt box

3. Directly on the code

#pragma mark-cllocationmanagerdelegate

-(void) startlocation{

self. Locationmanager = [[cllocationmanager alloc] init];

self. Locationmanager . Delegate = Self ;

}

-(void) Locationmanager: ( Cllocationmanager *) Manager didchangeauthorizationstatus: (clauthorizationstatus) status{

Switch (status) {

case kclauthorizationstatusnotdetermined:

if([self. Locationmanager respondstoselector:@selector(requestalwaysauthorization)]) {

[self. Locationmanager requestwheninuseauthorization];

}

break;

case kclauthorizationstatusdenied:

[uialertview bk_alertviewwithtitle:@ " please set the - Privacy -Location- enabled service! " ];

break;

case kclauthorizationstatusrestricted:

[uialertview bk_alertviewwithtitle:@ " positioning Service is not available! "];

default:

break;

}

}

4. Use Mkmapview positioning directly after opening.
