无法为cashape图层设置图像

Question

1.i已经创建了CAshapelayer并且还在CAshapelayer中成功插入了一个标签，但现在我正在尝试在图层中设置图像，但它无法正常工作。

1. 帮助我为此图层制作放大动画。

        CAShapeLayer *circleLayer = [CAShapeLayer layer];
    [circleLayer setPath:[[UIBezierPath bezierPathWithOvalInRect:CGRectMake(50, 250, 100, 100)] CGPath]];
   circleLayer.contents = (id)[[UIImage imageNamed:@"001-forward.png"] CGImage];
   circleLayer.contentsGravity=kCAGravityResize;
     //  circleLayer.masksToBounds = YES;
   [circleLayer setStrokeColor:[[UIColor brownColor] CGColor]];
   [circleLayer setFillColor:[[UIColor clearColor] CGColor]];
   
    [[self.view layer] addSublayer:circleLayer];
   CATextLayer *label = [[CATextLayer alloc] init];
   [label setFont:@"Helvetica-Bold"];
   [label setFontSize:15];
   [label setFrame:CGRectMake(50,300, 100, 50)];
   [label setString:@"GM"];
   [label setAlignmentMode:kCAAlignmentCenter];
   [label setForegroundColor:[[UIColor greenColor] CGColor]];
   
   [circleLayer addSublayer:label];
   

Answer 1

这里的主要问题是您无法添加UIImage作为CAShape Layer的内容，正如您在UIImage as CAShapeLayer contents所见，所以我修改了您的代码，将Image添加到{ {1}}并将该图层添加到circleLayer

CALayer

Answer 2

试试这个

CAShapeLayer *circleLayer = [CAShapeLayer layer];
[circleLayer setPath:[[UIBezierPath bezierPathWithOvalInRect:CGRectMake(50, 250, 100, 100)] CGPath]];
circleLayer.bounds = [[UIBezierPath bezierPathWithOvalInRect:CGRectMake(50, 250, 100, 100)] bounds];
circleLayer.masksToBounds = YES;
[circleLayer setStrokeColor:[[UIColor brownColor] CGColor]];
//Use .png if you store your image outside of .xcassets
circleLayer.fillColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"001-forward.png"]].CGColor;

[[self.view layer] addSublayer:circleLayer];
