我正在尝试使用Xcode 4.3中的pdf工具包读取pdf应用程序,但它给了我以下错误

ld: duplicate symbol _OBJC_METACLASS_$_OverlayManager in /Users/dt4it/Library/Developer/Xcode/DerivedData/MyPdf4-bmkjglhhvneluqcbwpceiqjvdcmq/Build/Intermediates/MyPdf4.build/Debug-iphonesimulator/MyPdf4.build/Objects-normal/i386/OverlayManager-D0866CFD31A05E68.o and /Users/dt4it/Library/Developer/Xcode/DerivedData/MyPdf4-bmkjglhhvneluqcbwpceiqjvdcmq/Build/Intermediates/MyPdf4.build/Debug-iphonesimulator/MyPdf4.build/Objects-normal/i386/OverlayManager-B31AE7412100AF6D.o for architecture i386
Command /Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

有什么帮助吗？

我想转换整数0和1BOOLEAN YES和NO

我的代码:

    NSNumber *num = 0;
    BOOL myBool = [num boolValue];
    NSLog(@"bool is: %@",myBool);

它给出了输出 (null)

可能有什么不对？

我怎么能叫applicationDidEnterBackground,在AppDelegate从viewController？

我想在应用程序的后台运行一个功能,而无需按下主页按钮.

我正在创建Android应用程序,在用户设置的时间内进行通知,当我设置时间时,此时,App会给出以下异常

在该类的AlarmReceiver.java类中

 TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

我花了很长时间尝试它,直到现在我无法达成解决方案.希望有人能帮助我.提前致谢.

我正在使用标记拖动在谷歌地图v2中绘制折线,这是我的代码

int startDraw = 1;
Polyline polyline;
List<LatLng> lineCordinates = new ArrayList<LatLng>();
List<Polyline> polylines = new ArrayList<Polyline>();

@Override
public void onMarkerDrag(Marker marker) {
    // startDraw == 0 --> stop draw
    // startDraw == 1 --> start draw

if (startDraw == 1) {

    Integer markerId = markerMapHash.get(marker);

    if (markerId == null) {
        markerId = 1;
    }

    if (markerId == 1) {
        lineCordinates.add(marker.getPosition());

    }


    for (int i = 0; i < lineCordinates.size(); i++) {

        polyline = myMap.addPolyline(new PolylineOptions()
        .addAll(lineCordinates)
        .width(lineWidth)
        .color(lineColor));

        polylines.add(polyline); …

我创建了一个Android应用程序,使用谷歌地图API V2显示谷歌地图,它在我的手机上与我很好.但是,当我将此应用程序的apk上传到(Google Play商店)时,它不会显示我的地图.

谁能告诉我为什么？以及如何解决这个问题？
