尝试在 MKAnnotation 中添加 UIImage

发布于 2024-11-03 02:01:07 字数 456 浏览 3 评论 0原文

我尝试在 MKAnnotation 中使用 UIImage：

UIView *leftCAV = [[UIView alloc] initWithFrame:CGRectMake(0,0,32,32)];
    leftCAV.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"..."]];
pin.leftCalloutAccessoryView = leftCAV;

代码已运行，但没有透明背景

请参阅：

有想法吗？

谢谢：）

I try to have a UIImage in a MKAnnotation:

UIView *leftCAV = [[UIView alloc] initWithFrame:CGRectMake(0,0,32,32)];
    leftCAV.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"..."]];
pin.leftCalloutAccessoryView = leftCAV;

The code is run, but I don't have a transparent background

See that:

有什么理由不只使用 imageView 吗？

UIImageView *iconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Location.png"]];
annotationView.leftCalloutAccessoryView = iconView;

Any reason not just using an imageView?

UIImageView *iconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Location.png"]];
annotationView.leftCalloutAccessoryView = iconView;

你尝试过吗：

leftCAV.backgroundColor = [UIColor clearColor];

？

我假设你的图像是 32x32。它有透明背景吗？（我无法判断我在您提供的链接中看到的内容是否是您想要的。该网站上发生的事情太多了！:-)

Did you try:

leftCAV.backgroundColor = [UIColor clearColor];

I'll assume your image is 32x32. Does it have a transparent background? (I could not tell if what I was looking at at the link you provided was what you intended. There's too much going on on that site! :-)
