GPS标签重叠在artoolkit中ios

我正在使用ARToolkit sdk用于基于位置的AR，用于在相机上显示geolocation点。我已经为ios实现了这个sdk，并且我有一个问题，即两个gps点在同一方向上彼此重叠。如何解决这个问题，请帮助我。GPS标签重叠在artoolkit中ios

我在AugmentedRealityController.m类的updateLocations方法中有一些小的变化。根据距离我正在调整屏幕上的标签高度，但问题没有解决，如何使两个重叠标记之间的差距。

if ([item distanceFromOrigin]>= 50 && [item distanceFromOrigin]<= 100) { 
       scaleFactor = 1.2; 
       loc.y = loc.y - 20;    
      } 
      else if ([item distanceFromOrigin]>= 100 && [item distanceFromOrigin]<= 150) { 
       scaleFactor = 0.8; 
       loc.y = loc.y - 50; 

      } 
      else if ([item distanceFromOrigin]>= 150 && [item distanceFromOrigin]<= 200) { 
       scaleFactor = 0.6; 
       loc.y = loc.y - 80; 
      } 
      else if ([item distanceFromOrigin]>= 200 && [item distanceFromOrigin]<= 300) { 
       scaleFactor = 0.6; 
       loc.y = loc.y - 100; 

      } 
      else if ([item distanceFromOrigin]>= 300 && [item distanceFromOrigin]<= 400) { 
       scaleFactor = 0.6; 
       loc.y = loc.y - 120; 
      } 
      else if ([item distanceFromOrigin]>= 400 && [item distanceFromOrigin]<= 500) { 
       scaleFactor = 0.5; 
      } 
      else if ([item distanceFromOrigin]>= 500 && [item distanceFromOrigin]<= 600) { 
       scaleFactor = 0.5; 
      } 
      else if ([item distanceFromOrigin]> 500) 
      { 
       scaleFactor = 0.5; 
      } 
      [markerView setFrame:CGRectMake(loc.x - width/2.0, loc.y -[item radialDistance]/100, width, height)]; 
      //   [markerView setFrame:CGRectMake(loc.x - width/2.0, loc.y, width, height)]; 
      [markerView setNeedsDisplay]; 
}

如果有人对如何解决此问题有所了解，请帮助我。

我通过对代码进行一些更改，解决了标注冲突的问题。

1）在AugmentedRealityViewController有updateLocations方法，进入if条件和

if (!([markerView superview])) { 
[[self displayView] insertSubview:markerView atIndex:1]; 
[self listSubviewsOfView:markerView]; // retrive the subviews from the markerview which is display on the camera screen... 
}

这个条件updatelocation方法和我称之为listSubviewsOfView方法，即用于从superViewsubview retriving。

(void)listSubviewsOfView:(UIView *)view { 

// Get the subviews of the view 
NSArray *subviews = [view subviews]; 

// Return if there are no subviews 
if ([subviews count] == 0) return; 

for (UIView subview in subviews) { 
if ([subview isKindOfClass:[UIImageView class]]) { 

UIImageView *myLabel = (UIImageView *)subview; 
myLabel.clipsToBounds = YES; 
if (myLabel.tag == 1) 
{ 
numberOfImageView++; 
CGRect rect = myLabel.frame; 
rect.origin.y = 0+numberOfImageView50; 
myLabel.frame = rect; 
} 

} 
// List the subviews of subview 
[self listSubviewsOfView:subview]; 
} 
} 

//there is variable numberOfImageView. declare in .h file 
int numberOfImageView; 

//and do one thing in else condition of the updateLocation Method , set the "numberOfImageView" to zero. 
else 
if ([markerView superview]) 
{ 

    [markerView removeFromSuperview]; 
    numberOfImageView =0; 
}

然后编译并运行

这段代码会调整图像，但是当你触摸图像时它将不会被触摸。 – user3249432 2014-12-20 09:02:30

在你AugmentedRealityViewController的更新位置的方法做一些改动就可以计算出两个标记视图之间的差异，然后设置标志的值y位置。

for (ARGeoCoordinate *item in [self coordinates]) { 
UIView *markerView = [item displayView]; 
if ([self shouldDisplayCoordinate:item]) { 
CGPoint loc = [self pointForCoordinate:item]; 
      CGFloat scaleFactor = SCALE_FACTOR; 

      if ([self scaleViewsBasedOnDistance]) 
       scaleFactor = scaleFactor - [self minimumScaleFactor]*([item radialDistance]/[self maximumScaleDistance]); 

      float width = [markerView bounds].size.width * scaleFactor; 
      float height = [markerView bounds].size.height * scaleFactor; 
if ([item distanceFromOrigin]>0) { 
      float difference = [item distanceFromOrigin]-prevLoc; 

     if ((difference>0 &&difference<200) || (difference < 0 && difference>(-200))) { 
          [markerView setFrame:CGRectMake(loc.x - width/2.0, loc.y-difference, width, height)]; 

     } 
    prevLoc = [item distanceFromOrigin]; 
     } 
} 
else if ([markerView superview]) 
{ 
    [markerView removeFromSuperview]; 
} 
}

prevLoc是float类型变量，在.h文件中声明并在init方法中初始化为零。

它会管理标记为了定位。
