使用 CAShapeLayer 填充颜色问题

Question

我想用文字 inside.Unable 画一个圆来显示 text.Any 帮助？

下图为参考。对于预期的行为。

以下代码供参考：

UILabel *lblTitle = [[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)];
lblTitle.text = @"Me";
lblTitle.textColor = [UIColor blackColor];

lblTitle.font = [UIFont fontWithName:@"HelveticaNeueLight" size:10.0] ;

lblTitle.textAlignment = NSTextAlignmentCenter;
[view addSubview:lblTitle];

CAShapeLayer *circleLayer = [CAShapeLayer layer];
circleLayer.path = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(0, 0, 40, 40)].CGPath;
circleLayer.fillColor = [UIColor clearColor].CGColor;
circleLayer.fillColor = [UIColor colorWithRed:56.0/255.0 green:212.0/255.0 blue:203.0/255.0 alpha:1.0f].CGColor;
circleLayer.strokeColor = [UIColor blackColor].CGColor;
circleLayer.lineWidth = 1;
[lblTitle.layer addSublayer:circleLayer];

Answer 1

您可以设置 UILabel 的 cornerRadius，如@Sujay 所说：

UILabel *lblTitle = [[UILabel alloc]initWithFrame:CGRectMake(100, 80, 40, 40)];
lblTitle.text = @"Me";
lblTitle.textColor = [UIColor blackColor];

lblTitle.layer.borderWidth = 1;
lblTitle.layer.borderColor = [UIColor blackColor].CGColor;
lblTitle.layer.cornerRadius = lblTitle.bounds.size.height / 2;
lblTitle.layer.masksToBounds = YES;
lblTitle.backgroundColor = [UIColor colorWithRed:56.0/255.0 green:212.0/255.0 blue:203.0/255.0 alpha:1.0f];

lblTitle.font = [UIFont fontWithName:@"HelveticaNeueLight" size:10.0] ;

lblTitle.textAlignment = NSTextAlignmentCenter;
[self.view addSubview:lblTitle];
