GPS標籤重疊在artoolkit中ios

我正在使用ARToolkit sdk用於基於位置的AR，用於在相機上顯示geolocation點。我已經爲ios實現了這個sdk，並且我有一個問題，即兩個gps點在同一方向上彼此重疊。如何解決這個問題，請幫助我。GPS標籤重疊在artoolkit中ios

我在AugmentedRealityController.m類的updateLocations方法中有一些小的變化。根據距離我正在調整屏幕上的標籤高度，但問題沒有解決，如何使兩個重疊標記之間的差距。

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]; 
}

如果有人對如何解決此問題有所瞭解，請幫助我。

我通過對代碼進行一些更改，解決了標註衝突的問題。

1）在AugmentedRealityViewController有updateLocations方法，進入if條件和

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... 
}

這個條件updatelocation方法和我稱之爲listSubviewsOfView方法，即用於從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; 
}

然後編譯並運行

這段代碼會調整圖像，但是當你觸摸圖像時它將不會被觸摸。 – user3249432 2014-12-20 09:02:30

在你AugmentedRealityViewController的更新位置的方法做一些改動就可以計算出兩個標記視圖之間的差異，然後設置標誌的值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類型變量，在.h文件中聲明並在init方法中初始化爲零。

它會管理標記爲了定位。
