一：指南针
#import <CoreLocation/CoreLocation.h>
CLLocationManager *locManger = [[CLLocationManager alloc] init];
locManger.delegate = self;
locManger.headingFilter = 0.1;// 最小变化度数
[locManger startUpdatingHeading];// 开始更新方向
// 代理方法
- (void)locationManager:(CLLocationManager*)manager didUpdateHeading:(CLHeading*)newHeading {
if(newHeading.magneticHeading == 0) {// 0度表示北方，180度表示南方
NSLog(@"北方");
} else if(newHeading.magneticHeading == 180) {
NSLog(@"南方");
}}
二：GPS
#import <CoreLocation/CoreLocation.h>
CLLocationManager *locManger = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;// 设置委托
[self.locationManager setDesiredAccuracy:CLLocationDistanceMax];// 设置精度为最优
[self.locationManager setDistanceFilter:(100.0)];// 设置更新的最小距离100米
[self.locationManager startUpdatingLocation];// 开始更新位置信息
回调方法
- (void)locationManager:(CLLocationManager*)manager
didUpdateLocations:(NSArray*)locations {
CLLocation *nowLocation = [locations lastObject];// 获取当前位置
CLLocationDegrees longitutude = newLocation.coordinate.longitude;// 获取经度
CLLocationDegrees latitude = newLocation.coordinate.latitude;// 获取纬度
}
// 计算距离
-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
double distance = [newLocation distanceFromLocation:oldLocation]; NSLog(@"distance = %lf", distance);
}
三：加速计
1.获得加速计对象
UIAccelerometer*accelerometer = [UIAccelerometersharedAccelerometer];
accelerometer.delegate=self;// 设置委托
// 设置更新间隔时间
accelerometer.updateInterval=1.0f/30.0f;
2.回调方法
- (void)accelerometer:(UIAccelerometer*)accelerometer didAccelerate:(UIAcceleration*)acceleration {
self.xLabel.text= [NSString stringWithFormat:@"%f",acceleration.x];// 获得x轴原始数据
self.yLabel= [NSString stringWithFormat:@"%f",acceleration.y];// 获得y轴原始数据
self.zLabel= [NSString stringWithFormat:@"%f",acceleration.z];// 获得z轴原始数据
}
四：摇一摇
// 在Controller中重写此方法，就可以获取摇一摇事件
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent*)event {
if (motion == UIEventSubtypeMotionShake) {
// 检测到了，手机摇一摇
}}
