小编Har*_*ari的帖子

我的地图中有两个叠加选项:MKCircleOverlay和MKPolygonOverlay.第一个是可变半径,通过UISlider控制.最后一个是根据角的数量和位置自定义.如果我改变非常快的圆的半径(减少UISlider的值)有时候我的叠加层会消失(圆圈),之后不能再绘制多边形了(当然也是圆圈).没有崩溃的应用程序.可能是什么？

这是我使用的一些代码:

- (IBAction) addCircle:(id)sender
{
slider.hidden = NO;
slider.transform = CGAffineTransformMakeRotation(M_PI*(-0.5));

_longPressRecognizer= [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
_longPressRecognizer.minimumPressDuration = 1.0; 

[mapview addGestureRecognizer:_longPressRecognizer];
[_longPressRecognizer release];
}

- (void)handleLongPress:(UIGestureRecognizer *)gestureRecognizer
{
if (gestureRecognizer.state != UIGestureRecognizerStateBegan)
    return;
CGPoint touchPoint = [gestureRecognizer locationInView:mapview];    
CLLocationCoordinate2D touchMapCoordinate = [mapview convertPoint:touchPoint toCoordinateFromView:mapview];

MKPointAnnotation *pa = [[MKPointAnnotation alloc] init];
pa.coordinate = touchMapCoordinate;
pa.title = @"Circle Based Search";

[mapview addAnnotation:pa];
[pa release];

tmC = touchMapCoordinate;
double radius = 1000.0;

self.circleOverlay = [MKCircle circleWithCenterCoordinate:tmC radius:radius];
[mapview removeOverlays:[mapview overlays]];
[mapview addOverlay:circleOverlay]; …

我是facebook graph api的新手,实际上我今天刚刚开始,所以我可能会使用一些帮助.

我的代码工作得很好,我写了一个简单的算法来列出喜欢某个帖子的人,但问题是这个.这是我从图api得到的JSON回复:

<br/>
{<br/>
            "likes": {<br/>
            "data": [<br/>
               {<br/>
                   "name": "NAME",<br/>
                   "id": "ID"<br/>
               },<br/>
               {<br/>
                   "name": "NAME",<br/>
                   "id": "ID"<br/>
               },<br/>
               {<br/>
                   "name": "NAME",<br/>
                   "id": "ID"<br/>
               },<br/>
               {<br/>
                   "name": "NAME",<br/>
                   "id": "ID"<br/>
               }<br/>
           ],<br/>
  "count": 22<br/>
},<br/>
"id": "POST ID",<br/>
"created_time": "DATE CREATED"<br/>
}<br/>

所以即使有COUNT:22喜欢,服务器只返回4个名字.是否有可能得到所有的名字？如果是这样,怎么样？

出于身份验证的目的,我将请求范围的支持bean注入另一个将存储已记录用户的会话范围bean.或者至少它应该...以下,一些代码:

请求scoped bean - 托管属性

@ManagedProperty(value="userLogin")

错误 无法为托管bean凭据设置属性userLogin

正如问题所示,我需要向上或向下舍入到最接近的20,除了0-14之外的数字,所有都必须舍入到20,因为不允许零值.表格不能用新值更新.现在我只管理了向上或向下舍入到最接近的100,如下所示:

 CASE WHEN ROUND(number,-2)=0 THEN CAST(ROUND(number,-2)+100 AS DECIMAL(18, 0)) 
      ELSE CAST(ROUND(number,-2) AS DECIMAL(18,0)) END AS [NUMBER]

我为我添加了一个MKCircle叠加层mapview,我想知道一个点(点击屏幕)是否在圆圈内.这是我的代码:

- (BOOL)pointInsideOverlay:(CLLocationCoordinate2D )tapPoint overlay:(id<MKOverlay>)overlay  {

   BOOL isInside = FALSE;
   MKPolygonView *polygonView = (MKPolygonView *)[self.mapView viewForOverlay:overlay];
   MKMapPoint mapPoint = MKMapPointForCoordinate(tapPoint);
   CGPoint polygonViewPoint = [polygonView pointForMapPoint:mapPoint];
   BOOL mapCoordinateIsInPolygon = CGPathContainsPoint(polygonView.path, NULL, polygonViewPoint, NO);

   if (mapCoordinateIsInPolygon) {
       isInside = TRUE;
   }
   return isInside;
}

viewForOverlay,pointForMapPoint&path已弃用.这是问题吗？

谢谢.

对于YouTube API，唯一的文档范围是http://gdata.youtube.com，它要求用户具有完全的读/写访问权限。是否有一个范围要求/授予只读权限，或者只是读取对Youtube Insight数据的权限？
