需要准备工作按照下图引进类库
需要添加
添加的两个字符串为:nslocationwheninuseusagedescription / nslocationalwaysusagedescription
默认定位设置:
设置工作准备完毕上代码:

建一个类:
//.h
#import <foundation/foundation.h>
@interface mypoint : nsobject<mkannotation>
//实现mkannotion协议必须要定义这个属性
@property (nonatomic,readonly)cllocationcoordinate2d coordinate;
//标题
@property (nonatomic,copy)nsstring *title;
//初始化方法
- (id)initwithcoordinate:(cllocationcoordinate2d)c andtitle:(nsstring *)t;
//.m
@implementation mypoint
- (id)initwithcoordinate:(cllocationcoordinate2d)c andtitle:(nsstring *)t{
if (self = [super init]) {
_coordinate = c;
_title = t;
return self;
最终效果:
