自定义MKA注释按钮 [英] Custom MKAnnotation button

问题描述

我想使用MKAnnotation生成自定义注释.

I'd like to generate a custom annotation using MKAnnotation.

annotationView?.image = UIImage(named: "annotation)") // this is to set the annotation image
annotationView?.leftCalloutAccessoryView = UIImageView(image: UIImage(named: "mySymbol")) // this is to add a icon left to the annotation UI

上面的几行工作正常，但是...现在，我想像上面的图片一样在注释"中添加自定义按钮.

The few lines above are working quiet well but ... now I'd like to add a custom button to the Annotation like in the image above.

到目前为止，使用默认选项是可行的:

Using the default one is working so far :

annotationView?.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)

...但是不使用自定义按钮(只是不显示UI元素，仍然没有):

... but using a custom one is not (Just not showing a UI element, there is still NOTHING):

let myButton = UIButton(type: .custom)
myButton.setImage(UIImage(named: "myButton"), for: .normal)
annotationView?.rightCalloutAccessoryView = myButton

---

我不知道如何继续...我希望有人能够解决这个小问题.

I have no clue how to go on... I hope somebody is able to fix this small problem.

提前感谢，乔纳斯

推荐答案

我是提问者:-)

我自己找到了一个解决方案，没有创建一个完整的新视图-就像@Sh_Khan提到的那样-因为这仍然没有必要.

I found a solution on my own without creating a complete new view - like @Sh_Khan mentioned - because this is still not necessary.

这是我想出的:

let button = UIButton()
button.setImage(UIImage(named :"myIcon")?.withRenderingMode(.alwaysTemplate), for: .normal)
button.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
annotationView?.rightCalloutAccessoryView = button
