的iOS MapBox RMShape

Question

我是新來使用RMPolylines和RMShapes和我認爲我正確地執行這個代碼，但沒有什麼是地圖上顯示了：

RMMapBoxSource *tilesource = [[RMMapBoxSource alloc] initWithMapID:kMapID]; 

[mapView setTileSource:tilesource]; 

NSArray *locations = [NSArray arrayWithObjects:[[CLLocation alloc] initWithLatitude:-33.981595 longitude:151.072900],[[CLLocation alloc] initWithLatitude:-33.981560 longitude:151.073544],[[CLLocation alloc] initWithLatitude:-33.981560 longitude:151.073845],[[CLLocation alloc] initWithLatitude:-33.981666 longitude:151.074016], nil]; 

RMAnnotation *annoation43 = [[RMAnnotation alloc] initWithMapView:mapView coordinate:((CLLocation *)[locations objectAtIndex:0]).coordinate andTitle:@"Hola biatches!"]; 

annoation43.userInfo = locations; 
[annoation43 setBoundingBoxFromLocations:locations]; 
[mapView addAnnotation:annoation43]; 

-(RMMapLayer *)mapView:(RMMapView *)mapViewer layerForAnnotation:(RMAnnotation *)annotation 
{ 
    if (annotation.isUserLocationAnnotation) 
     return nil; 

    RMShape *shape = [[RMShape alloc] initWithView:mapView]; 

    shape.lineColor = [UIColor orangeColor]; 
    shape.lineWidth = 5.0; 

    for (CLLocation *location in (NSArray *)annotation.userInfo) 
     [shape addLineToCoordinate:location.coordinate]; 

    return shape; 
    NSLog(@"It is working Dora!"); 
} 

因此，我認爲我做錯了這裏，但我無法挑選 - 如果需要更多代碼或信息，請告訴我。

Answer 1

好吧現在已經修好了，好像是一個簡單的問題，但是如果你知道詳細的原因，我很樂意聽到它！

添加以下內容：

mapView.delegate = self; 

我以爲我已經設置委託，但顯然不是！

首先，您的NSLog()因爲return而不會運行，但那是次要的。

我看到你基本上跟着shape example。我不確定什麼是錯的。愚蠢的問題，但是屏幕上的形狀？即您的地圖視圖顯示此形狀覆蓋的區域？
