使用cocos2d（2.0）自定義UIKit繪圖？

Question

我試圖在我要構建的游戲中在我的cocos層上使用自定義UiView。 當我說自定義UIView時，我想在UIView的繪制區域中編寫並使用自己的繪制代碼來創建視圖（使用貝塞爾曲線路徑）。 雖然我知道如何將UiView添加到屏幕上，如下所示：

  [[[CCDirector sharedDirector] view] addSubview:myView];

我的drawRect方法中的繪圖代碼似乎不起作用！

這是我如何設置cocos2d：

- (void)setupCocos2D {
       director = (CCDirectorIOS*) [CCDirector sharedDirector];
       CCGLView *glView = [CCGLView viewWithFrame:[[UIScreen mainScreen] bounds]
                     pixelFormat:kEAGLColorFormatRGB565 //kEAGLColorFormatRGBA8
                     depthFormat:0  //GL_DEPTH_COMPONENT24_OES
              preserveBackbuffer:NO
                    sharegroup:nil
                   multiSampling:YES
                 numberOfSamples:1024];
      [director setView:glView];
      [glView setMultipleTouchEnabled:NO];
      [director enableRetinaDisplay:NO];
      director.wantsFullScreenLayout = YES;
      [director setDisplayStats:YES];
      [director setDepthTest:YES];

      [director setAnimationInterval:1.0/60];

 }

以下是myView的draw rect方法中的自定義繪圖代碼：

  - (void)drawRect:(CGRect)rect
  {     //// General Declarations
       CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
       UIGraphicsBeginImageContext(self.bounds.size);
       context = UIGraphicsGetCurrentContext();


      //// Color Declarations
      UIColor* defaultMidGreen_COLOR = [UIColor colorWithRed: 0.231 green: 0.392 blue:  0.392 alpha: 1];
      UIColor* panelGradient_COLOR = [UIColor colorWithRed: 0.231 green: 0.392 blue: 0.392 alpha: 1];
      UIColor* default_0Opacity_COLOR = [UIColor colorWithRed: 0.231 green: 0.392 blue: 0.392 alpha: 0];
      UIColor* defaultDarkGreen_60Opacity_COLOR = [UIColor colorWithRed: 0.231 green: 0.392 blue: 0.392 alpha: 0.6];
      UIColor* iconPlayer_Fill_COLOR = [UIColor colorWithRed: 0.4 green: 0.8 blue: 0.769 alpha: 1];

      //// Gradient Declarations
     NSArray* bottom_GRADIENTColors = [NSArray arrayWithObjects:
                                  (id)panelGradient_COLOR.CGColor,
                                  (id)[UIColor colorWithRed: 0.231 green: 0.392 blue: 0.392 alpha: 0.5].CGColor,
                                  (id)default_0Opacity_COLOR.CGColor, nil];
    CGFloat bottom_GRADIENTLocations[] = {0, 0.55, 1};
    CGGradientRef bottom_GRADIENT = CGGradientCreateWithColors(colorSpace, (CFArrayRef)bottom_GRADIENTColors, bottom_GRADIENTLocations);


{
    //// panelComponent-BottomSolid Drawing
    solidPaths = [[UIBezierPath alloc] init];
    [solidPaths moveToPoint: CGPointMake(0, 110)];
    [solidPaths addLineToPoint: CGPointMake(540, 110)];
    [solidPaths addLineToPoint: CGPointMake(540, 60)];
    [solidPaths addLineToPoint: CGPointMake(0, 60)];
    [solidPaths addLineToPoint: CGPointMake(0, 110)];
    [solidPaths closePath];
    [defaultMidGreen_COLOR setFill];
    [solidPaths fill];




    //// panelComponent-BottomGradient Drawing
    gradientPaths = [[UIBezierPath alloc] init];
    [gradientPaths moveToPoint: CGPointMake(0, 2)];
    [gradientPaths addLineToPoint: CGPointMake(539, 2)];
    [gradientPaths addLineToPoint: CGPointMake(539, 60)];
    [gradientPaths addLineToPoint: CGPointMake(0, 60)];
    [gradientPaths addLineToPoint: CGPointMake(0, 2)];
    [gradientPaths closePath];
    CGContextSaveGState(context);
    [gradientPaths addClip];




    outline = [[UIBezierPath alloc ]init];
    [outline moveToPoint: CGPointMake(1, 109)];
    [outline addLineToPoint: CGPointMake(539, 109)];
    [outline addLineToPoint: CGPointMake(539, 0)];
    [outline addLineToPoint: CGPointMake(1, 0)];
    [outline addLineToPoint: CGPointMake(1, 109)];
    [outline closePath];
    [defaultDarkGreen_60Opacity_COLOR setFill];

    [iconPlayer_Fill_COLOR setStroke];
    outline.lineWidth = 1;



     gripLines = [[UIBezierPath alloc] init];
    [gripLines moveToPoint: CGPointMake(200, 3)];
    [gripLines addLineToPoint: CGPointMake(200, 2)];
    [gripLines addLineToPoint: CGPointMake(340, 2)];
    [gripLines addLineToPoint: CGPointMake(340, 3)];
    [gripLines addLineToPoint: CGPointMake(200, 3)];
    [gripLines closePath];
    [iconPlayer_Fill_COLOR setFill];
    [gripLines fill];

}

[solidPaths stroke];
[gripLines stroke];

[outline stroke];

//// Cleanup
UIGraphicsEndImageContext();
CGGradientRelease(bottom_GRADIENT);
CGColorSpaceRelease(colorSpace);

}

附加信息：

• 如果我嘗試在draw rect中設置backgroundColor屬性，則它不起作用。 但是，如果我使用顏色初始化對象（在init方法中），則同樣有效
• 我認為這與嘗試使用的圖形上下文有關，並且我正在使用的一個與cocos2D正在使用的一個之間存在沖突！ 雖然不確定！

任何幫助表示贊賞！

因此，經過幾個小時的環顧后，我得到了這個工作。

使用錯誤的上下文來得出我的觀點。

只需刪除此行。

 UIGraphicsBeginImageContext(self.bounds.size);
