Question

我想采用CALAYER数组： -

CALayer *layer3 = [CALayer layer];
    [layer3 setBounds:CGRectMake(0.0f, 0.0f, 10.0f, 10.0f)];
    [layer3 setCornerRadius:5.0f];
    [layer3 setMasksToBounds:YES];
    [layer3 setBackgroundColor:[[UIColor redColor] CGColor]];

    // Center the layer in the view.
    [layer3 setPosition:CGPointMake(x,y)];
[[self.Image layer3] addSublayer:layer3];

通过上述方式，我在图像中创造了一个点。但我想在图像中画出10点。我想拍摄CALAyer的照片。请帮帮我。我怎样才能拿出CALAYER阵列。

提前致谢

    NSMutableArray *Arr=[[NSMutableArray alloc] init];
    CALayer *layer1 = [CALayer layer];
        [layer1 setBounds:CGRectMake(0.0f, 0.0f, 10.0f, 10.0f)];
        [layer1 setCornerRadius:5.0f];
        [layer1 setMasksToBounds:YES];
        [layer1 setBackgroundColor:[[UIColor redColor] CGColor]];
         [Arr addObject:layer1];
    CALayer *layer3 = [CALayer layer];
        [layer3 setBounds:CGRectMake(0.0f, 0.0f, 10.0f, 10.0f)];
        [layer3 setCornerRadius:5.0f];
        [layer3 setMasksToBounds:YES];
        [layer3 setBackgroundColor:[[UIColor redColor] CGColor]];
        [Arr addObject:layer3];
    CALayer *layer4 = [CALayer layer];
        [layer4 setBounds:CGRectMake(0.0f, 0.0f, 10.0f, 10.0f)];
        [layer4 setCornerRadius:5.0f];
        [layer4 setMasksToBounds:YES];
        [layer4 setBackgroundColor:[[UIColor redColor] CGColor]];
        // [Arr addObject:layer4]; Center the layer in the view.

现在从阵列中获取单个图层... 我希望它会帮助你尝试一次
