自定義谷歌地圖標記圖標圖像在swift ios

Question

我轉換自定義視圖加載從xib到UIImage顯示爲標記icon.it完成，但問題是，當這樣做for循環顯示100個標記UI卡住是因爲加載xib自定義視圖？

下面

是函數調用在循環

func generateSpot(Prop: Property) -> Spot { 

    let latStr = Prop.propLat 
    let langStr = Prop.propLang as NSString 
    let langDbl : Double = Double(langStr.floatValue) 
    let latDbl : Double = Double(latStr.floatValue) 

    let marker:GMSMarker = GMSMarker() 
    marker.position = CLLocationCoordinate2DMake(langDbl,latDbl) 
    marker.appearAnimation = kGMSMarkerAnimationPop 
    marker.title = Prop.propBuildingName as String 
    marker.snippet = Prop.propCode as String 
    marker.infoWindowAnchor = CGPointMake(0.44, 0.45) 

    let sizeVar:CGSize = CGSize(width: 41, height: 37) 

    let customeMarker :CustomMarker = NSBundle.mainBundle().loadNibNamed("CustomView", owner: self.view, options: nil).first! as! CustomMarker 

    customeMarker.frame = CGRectMake(customeMarker.frame.minX,customeMarker.frame.minY,customeMarker.frame.width,customeMarker.frame.height) 
    customeMarker.mappedNumbers.layer.masksToBounds = true 
    customeMarker.mappedNumbers.layer.cornerRadius = 8 
    customeMarker.mappedNumbers.text = Prop.propSequence as String 

    if Prop.propStatus == self.constants!.status.STATUS_COMPLETED_XML 
    { 
     customeMarker.mappedNumbers.backgroundColor = self.utility!.uicolorFromHex(0x70b420) 
     customeMarker.arrowImage.tintColor = self.utility!.uicolorFromHex(0x70b420) 
    } 

    if Prop.propStatus == self.constants!.status.STATUS_DRAFT_XML 
    { 
     customeMarker.mappedNumbers.backgroundColor = self.utility!.uicolorFromHex(0xd2cb46) 
     customeMarker.arrowImage.tintColor = self.utility!.uicolorFromHex(0x70b420) 


    } 
    if Prop.propStatus == self.constants!.status.STATUS_PENDING_XML 
    { 
     customeMarker.mappedNumbers.backgroundColor = self.utility!.uicolorFromHex(0xd44646) 
     customeMarker.arrowImage.tintColor = self.utility!.uicolorFromHex(0xd44646) 


    } 


    UIGraphicsBeginImageContextWithOptions(sizeVar, false, 0) 
    customeMarker.drawViewHierarchyInRect(customeMarker.bounds, afterScreenUpdates: true) 

    let newImage = UIGraphicsGetImageFromCurrentImageContext() 
    UIGraphicsEndImageContext() 
    marker.icon = newImage 
    marker.map = self.googleMapView 
    let spotObje:Spot = Spot() 
    spotObje.location = marker.position 
    spotObje.marker = marker 
    return spotObje 
}

解決 更換

customeMarker.drawViewHierarchyInRect(customeMarker.bounds, afterScreenUpdates: true) 

與

customeMarker.layer.renderInContext(UIGraphicsGetCurrentContext()!) 

參考：drawViewHierarchyInRect:afterScreenUpdates: delays other animations
