我想找到近似形状的总数.

在图像中,有6个没有近似多边形.我试过以下方法

    for (NSInteger i = 0; i < [arrLinesInfo count]; i++) {

              NSDictionary *dictLineInfo = [arrLinesInfo objectAtIndex:i];

              startPoint = CGPointMake([[dictLineInfo valueForKey:@"line_start_point_x"] doubleValue], [[dictLineInfo valueForKey:@"line_start_point_y"] doubleValue]);
              endPoint = CGPointMake([[dictLineInfo valueForKey:@"line_end_point_x"] doubleValue], [[dictLineInfo valueForKey:@"line_end_point_y"] doubleValue]);

              [self isCircularRoute:startPoint withEndPoint:endPoint];
            }


            -(void) isCircularRoute:(CGPoint) lineStartPoint withEndPoint:(CGPoint) lineEndPoint 
            {
                NSPredicate *pre= [NSPredicate predicateWithFormat:[NSString stringWithFormat:@"
    (self.line_end_point_x == '%f' && self.line_end_point_y == '%f') OR 
        (self.line_start_point_x == '%f' && self.line_start_point_y == '%f') OR 
        (self.line_end_point_x == '%f' && self.line_end_point_y == '%f') OR
         (self.line_start_point_x == '%f' && self.line_start_point_y == '%f')", …

我需要拉伸图像右侧和左侧中心半圆保持原样。还需要在中心半圆

我试过切片概念，也试过下面的代码

UIImage *image = self.imgBGBottom.image;
CGFloat capWidth =  floorf(image.size.width / 2) - 50;
CGFloat capHeight =  0;
UIImage *capImage = [image resizableImageWithCapInsets:
                     UIEdgeInsetsMake(capHeight, capWidth, capHeight, capWidth)];

[self.imgBGBottom setImage:capImage];

但它对我不起作用

请帮我。提前致谢。

我已经做了大量的研发工作来过私人生日facebook,但却无法过私人生日.

我已经在代码中给了生日许可.还试图从用户的帐户删除应用程序,但没有运气.

if((FBSDKAccessToken.currentAccessToken()) != nil){
    FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, birthday, name, first_name, last_name, picture.type(large), email, gender"]).startWithCompletionHandler({ (connection, result, error) -> Void in
         if (error == nil){
             Print("Success")
         }else{
             Print("Failed")
         }
  })    
}else{
    Print("Device token is Nil")
}

请帮帮我,我的错误在哪里.
