iOS get current position latitude and longitude degree

Recently in doing a bus query project, you need to locate the current location in order to conduct a nearby site query, and you share how to obtain their current position latitude and longitude

First add the Corelocation.framework library:

Reference header file and declare cllocationmanagerdelegate agent:

Next, declare the variables you want to use:

@property (Strong, nonatomic) Cllocationmanager *locmanager;
@property (Strong, nonatomic) cllocation *checkinlocation;
@property (Strong, nonatomic) NSString *currentlatitude; Latitude
@property (Strong, nonatomic) NSString *currentlongitude;//Longitude

In Viewdidload, the user is determined whether the location service is enabled, and the system prompts for a positioning operation when the application is first entered. Then start locating the current location:

if ([Cllocationmanager locationservicesenabled]) {
        Self.locmanager = [[Cllocationmanager alloc] init];
        Self.locManager.delegate = self;
    } else{
        Uialertview *alert = [[Uialertview alloc] initwithtitle:@ ' warning ' message:@ ' unable to locate operation ' delegate:self cancelbuttontitle:@ "Determine" otherbuttontitles:nil, nil];
        [Alert show];
    }
    [Self.locmanager startupdatinglocation];

Invoke the Proxy method to update the current location:

-(void) Locationmanager: (Cllocationmanager *) Manager didupdatelocations: (Nsarray *) locations{
    self.checkinlocation = [Locations lastobject];
    Cllocationcoordinate2d cool = self.checkinLocation.coordinate;
    Self.currentlatitude  = [NSString stringwithformat:@ "%.4f", cool.latitude];
    Self.currentlongitude = [NSString stringwithformat:@ "%.4f", cool.longitude];
    
    NSLog (@ "%@,%@", self.currentlatitude,self.currentlongitude);
}

Run the program, the console also output the current position of latitude and longitude (cover the address, bad writing you can not find me):

Blog for the first time, I hope to be helpful to everyone, there are errors and deficiencies in the hope that we can make suggestions, learning the way to share with you, I was inspirational to become Mars Ape Man.
