度數轉換數據加速度計

Question

我想轉換度數據加速度。 但我不知道代碼（目標c）非常好。有人幫我意識到這一點？ 我需要看看度數而不是加速度計數據！ 我這樣：

#import "APLGraphViewController.h" 
#import "APLGraphView.h" 
#import "APLAppDelegate.h" 
#import "math.h" 
@interface APLGraphViewController() 
@property (weak, nonatomic) IBOutlet UILabel *xLabel; 
@property (weak, nonatomic) IBOutlet UILabel *yLabel; 
@property (weak, nonatomic) IBOutlet UILabel *zLabel; 
@property (weak, nonatomic) IBOutlet UISlider *updateIntervalSlider; 
@end 
@implementation APLGraphViewController 
#pragma mark - View lifecycle 
-(void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    self.updateIntervalSlider.value = 0.0f; 
} 
- (void)viewWillAppear:(BOOL)animated 
{ 
    [super viewWillAppear:animated]; 
    [self startUpdatesWithSliderValue:(int)(self.updateIntervalSlider.value * 100)]; 
} 
- (void)viewDidDisappear:(BOOL)animated 
{ 
    [super viewDidDisappear:animated]; 
    [self stopUpdates]; 
} 
#pragma mark - Responding to events 
- (IBAction)takeSliderValueFrom:(UISlider *)sender 
{ 
    [self startUpdatesWithSliderValue:(int)(sender.value * 100)]; 
} 
- (void)setLabelValueX:(double)x y:(double)y z:(double)z 
{ 
    self.xLabel.text = [NSString stringWithFormat:@"x: %f", x]; 
    self.yLabel.text = [NSString stringWithFormat:@"y: %f", y]; 
    self.zLabel.text = [NSString stringWithFormat:@"z: %f", z]; 
} 
- (void)setLabelValueRoll:(double)roll pitch:(double)pitch yaw:(double)yaw 
{ 
    self.xLabel.text = [NSString stringWithFormat:@"roll: %f", roll]; 
    self.yLabel.text = [NSString stringWithFormat:@"pitch: %f", pitch]; 
    self.zLabel.text = [NSString stringWithFormat:@"yaw: %f", yaw]; 
} 
#pragma mark - Update methods stub implementations 
- (void)startUpdatesWithSliderValue:(int)sliderValue 
{ 
    return; 
} 
- (void)stopUpdates 
{ 
    return; 
} 
@end 

我怎樣才能獲得學位？

謝謝

加速度計測量線性加速度，而不是角度旋轉。這聽起來像你想要陀螺儀數據（偏航，俯仰和滾轉）而不是加速計數據。查看CMDeviceMotion類的文檔。它提供了沿着3個軸的旋轉速率。
