需要準備工作按照下圖引進類庫
需要添加
添加的兩個字元串為:nslocationwheninuseusagedescription / nslocationalwaysusagedescription
預設定位設定:
設定工作準備完畢上代碼:

建一個類:
//.h
#import <foundation/foundation.h>
@interface mypoint : nsobject<mkannotation>
//實作mkannotion協定必須要定義這個屬性
@property (nonatomic,readonly)cllocationcoordinate2d coordinate;
//标題
@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;
