如何编写MKMapKitView的代码，当用户单击图钉时，该视图显示另一个容器视图？ [关闭]

Question

我想要ios应用程序的这种类型的输出。 我不知道该怎么做。 如果有人知道该怎么做，请告诉我。

编辑

我已经按照答案更新了代码，但仍然无法正常工作。 我无法理解UIView的显示方式以及它的大小是多少？

#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;
}

您必须创建一个自定义视图，才能在mapview上进行自定义标注。您必须创建一个包含自定义视图的类，该类将在点击时显示。 这是github上的示例代码。
