今天開(kāi)始總結(jié)一下地圖與定位。首先要使用定位就要引用框架CoreLocation.framework,在類文件中加入#import <CoreLocation/CoreLocation.h>,其次在IOS8中調(diào)用的時(shí)候要在Info.plist中加兩個(gè)Key,NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription,具體參考http://www.cnblogs.com/kenshincui/p/4125570.html

#import "ViewController.h" @interface ViewController ()<CLLocationManagerDelegate> @property(nonatomic,strong)CLLocationManager *locationManager; @end@implementation ViewController- (void)viewDidLoad {[super viewDidLoad];_locationManager=[[CLLocationManager alloc]init];//判斷定位服務(wù)是否可用BOOL enable= [CLLocationManager locationServicesEnabled];// //CLAuthorizationStatus // typedef NS_ENUM(int, CLAuthorizationStatus) { // //用戶尚未做出決定是否啟用定位服務(wù) // kCLAuthorizationStatusNotDetermined = 0, // //沒(méi)有獲得用戶授權(quán)使用定位服務(wù),可能用戶沒(méi)有自己禁止訪問(wèn)授權(quán) // kCLAuthorizationStatusRestricted, // //用戶已經(jīng)明確禁止應(yīng)用使用定位服務(wù)或者當(dāng)前系統(tǒng)定位服務(wù)處于關(guān)閉狀態(tài) // kCLAuthorizationStatusDenied, // //應(yīng)用獲得授權(quán)可以一直使用定位服務(wù)，即使應(yīng)用不在使用狀態(tài) // kCLAuthorizationStatusAuthorizedAlways NS_ENUM_AVAILABLE(NA, 8_0), // //使用此應(yīng)用過(guò)程中允許訪問(wèn)定位服務(wù) // kCLAuthorizationStatusAuthorizedWhenInUse NS_ENUM_AVAILABLE(NA, 8_0), // //已經(jīng)廢棄 // kCLAuthorizationStatusAuthorized NS_ENUM_DEPRECATED(10_6, NA, 2_0, 8_0, "Use kCLAuthorizationStatusAuthorizedAlways") = kCLAuthorizationStatusAuthorizedAlways //};if ([CLLocationManager authorizationStatus]<3&&enable) {//請(qǐng)求開(kāi)啟服務(wù)[_locationManager requestWhenInUseAuthorization];// [_locationManager requestAlwaysAuthorization];}else{ // _locationManager=[[CLLocationManager alloc]init];_locationManager.delegate=self;// kCLLocationAccuracyBestForNavigation //導(dǎo)航級(jí)別 // kCLLocationAccuracyBest;

?還有就是在模擬器中調(diào)試的問(wèn)題：可以選中模擬器的Debug——>Location 來(lái)定義經(jīng)緯度
