ios - 如何为 MKMapKit View 编写代码当用户单击 pin 时，它会显示另一个容器 View ？
我想要 ios 应用程序的这种类型的输出。我不知道该怎么做。如果有人知道怎么做，请告诉我。

我已经根据答案更新了我的代码，但它仍然无法正常工作。我无法理解 UIView 的显示方式及其大小？
#import <UIKit/UIKit.h>
@interface MyView : UIView
@end
#import "MyView.h"
@implementation MyView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self)
{
// Initialization code
// initilize all your UIView components
UILabel *label1 = [[UILabel alloc]initWithFrame:CGRectMake(20,30, 200, 44)];
label1.text = @"i am label 1";
[self addSubview:label1]; //add label1 to your custom view
UILabel *label2 = [[UILabel alloc]initWithFrame:CGRectMake(20,80, 200, 44)];
label2.text = @"i am label 2";
[self addSubview:label2]; //add label2 to your custom view
}
return self;
}

最佳答案
您必须制作一个自定义 View 才能在 mapview 上制作自定义标注。您必须制作一个包含自定义 View 的类，该类将在 pin tapped 上。这是github上的示例代码。
