RMPolylineAnnotation未出現在地圖上（地圖框）

我正在嘗試將RMPolylineAnnotation添加到我的地圖框地圖中，但由於某種原因它沒有出現。我不確定是否缺少在繪圖過程中使用的調用或函數。我使用的是添加它的代碼如下：RMPolylineAnnotation未出現在地圖上（地圖框）

for (id key in dFeatures) 
     { 
      RMPolylineAnnotation *polylineAnnotation = [[RMPolylineAnnotation alloc] initWithMapView:self.rmMapView points:[dFeatures objectForKey:key]]; 
      [polylineAnnotation setLineWidth:10.0f]; 
      [polylineAnnotation setLineColor:[UIColor orangeColor]]; 

      [self.rmMapView addAnnotation:polylineAnnotation]; 
     }

dFeatures只是包含在我的RMPolylineAnnotations的初始化使用的點衆多陣列字典，見下圖：

(lldb) po dFeatures

這一切似乎加載正常，並顯示我有一個有效的RMPolylineAnnotation，如果我在它後面設置了一個斷點，但沒有顯示在地圖上。我已經注意到了這一點上來的，雖然LLDB：

2014-02-28 11:36:56.579 WildSheffield[7700:70b] -[<RMShape: 0xc13aee0> display]: Ignoring bogus layer size (397983.125000, 470151.031250)

我猜這是問題的原因，但我不明白爲什麼層走出過大，以致我的座標陣列都位置相當密切。

任何人都可以提供任何建議如何解決這個問題？我已經仔細閱讀了參考文檔，但似乎無法弄清楚我做錯了什麼。感謝

編輯1：

我注意到，當我放大到地圖我現在得到以下錯誤：

：CGContextPathContainsPoint：無效的上下文爲0x0。這是一個嚴重錯誤。此應用程序或其使用的庫正在使用無效的上下文，從而導致系統穩定性和可靠性的總體降級。此通知是禮貌性的：請修復此問題。這將成爲即將到來的更新中的致命錯誤。

這可能是問題的原因，但我不知道爲什麼它會發生，因爲我的路線肯定屬於地圖邊界等。有沒有我沒有添加的圖書館潛在？

編輯2：

我也注意到，雖然我設置我的rmMapView委託該功能不會被調用：

- (RMMapLayer *)mapView:(RMMapView *)mapView layerForAnnotation:(RMAnnotation *)annotation

是否RMPolylineAnnotation不能算作實際註釋（即如果它不調用這個方法？），for循環肯定會將它添加到RMMapView中的'_visibleAnnotations'數組中。

你能解決你的問題了嗎？ – P5ycH0

你是否設法解決這個問題？ – Joze

它在我看來就像是爲您的集合中的每個點添加一條折線實例，而不是包含所有這些點的一條折線。

沒有抱歉我應該更清楚一點，字典可以包含多個數組。我使用密鑰名稱來標識不同的數組，因此您可以看到該字典包含一個名爲'Blacka_trail_a'的密鑰條目，而[dFeatures objectForKey：key]訪問使用此密鑰名稱存儲的數組。這就是爲什麼我對發生的事情感到困惑，因爲我覺得其餘的代碼應該是正確的？ –

嗨，我已經更新了我原來的帖子，顯示縮放後顯示的錯誤，你知道我爲什麼現在會得到這個錯誤嗎？謝謝。 –

我想我可能會調用這個錯誤的地方，我目前有這個代碼在viewDidLoad運行，我猜它需要比這更晚調用。有關代碼放置位置的任何建議？ –

我有完全相同的錯誤，它是由我的代碼返回長度爲零的線（RMShape *）導致的（即P1和P2是相同的點）。看起來，這在層渲染代碼中造成了一些零問題。我的代碼大致如下，並通過添加if（）部分，沒有更多的錯誤:-)

RMShape *path = [[RMShape alloc] initWithView:mapView]; 
CLLocation * p1 = _currentWayPoint.coord; 
... 
CLLocation * p2 = bisectLocation; 

float bisectLength = [p1 distanceFromLocation:p2]; 
if (bisectLength == 0.0f) 
{ 
    NSLog(@"Ignoring invalid bisect length %f", bisectLength); 
    return nil; 
} 

[path moveToCoordinate:p1.coordinate]; 
[path addLineToCoordinate:p2.coordinate]; 
return path;
