iphone - 在圆圈上移动标签

Question

我有一个会翻的圈子，我怎么给他贴一些会跟着他翻的标签？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形图像的 UIView 上，或者如果您不使用 IB，只需将标签添加到圆形，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"];
