Question

我有一个转过来的圆圈，我怎么能给他贴上一些随身携带的标签呢？我的观点是圆圈和标签应该在同一个天使上。

Answer 1

使标签成为您用来呈现圆圈的UIView的子视图。在IB中，只需将标签拖到您用于圆圈图像的UIView上，或者如果您不使用IB，只需将标签添加到圆圈中，如下所示： [circleUIView addSubview:theUILabel];

Now changes into Canvas.m file's animateCicleAlongPath method.

Replace to image to label.

UILabel *label = [[UILabel alloc]init];
    [label setText:@"test"];
    [label setTextColor:[UIColor redColor]];
    //Set the frame of the view - which is used to position it when we add it to our current UIView
    label.frame = CGRectMake(1, 1, 20, 20);
    label.backgroundColor = [UIColor clearColor];
    [self addSubview:label];
    [label.layer addAnimation:pathAnimation forKey:@"moveTheSquare"];
