iOS 8定位补充
iOS 8定位需要修改2个地方
1.info.plist文件中添加NSLocationAlwaysUsageDescription:描述信息
从iOS 8开始,用户定位分两种情况
总是使用用户位置:NSLocationAlwaysUsageDescription
使用应用时定位:NSLocationWhenInUseDescription
2.在CLLocationManager中调用
- (void)requestAlwaysAuthorization
- (void)requestWhenInUseAuthorization
#import "ViewController.h" #import <CoreLocation/CoreLocation.h> @interface ViewController () <CLLocationManagerDelegate> @property(nonatomic,strong)CLLocationManager *mgr; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; [self.mgr startUpdatingLocation]; // 如果是iOS8,需要请求授权方式(进行判断,否则在iOS7会崩溃,需要先在info.plist中配置) // 1.通过判断系统判断来确定是否需要请求requestAlwaysAuthorization授权 // if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) { // [self.mgr requestAlwaysAuthorization]; // } // 2.通过判断是否有该方法来判断是否需要请求requestAlwaysAuthorization授权 if ([self.mgr respondsToSelector:@selector(requestAlwaysAuthorization)]) { [self.mgr requestAlwaysAuthorization]; } } - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations { NSLog(@"获取到用户的位置"); } - (CLLocationManager *)mgr { if (_mgr == nil) { _mgr = [[CLLocationManager alloc] init]; _mgr.delegate = self; } return _mgr; } @end
