需要准備工作按照下圖引進類庫

需要添加

添加的兩個字符串為:NSLocationWhenInUseUsageDescription / NSLocationAlwaysUsageDescription

 

默認定位設置:

 

設置工作准備完畢上代碼:

指示根視圖:

 

    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:23/255.0 green:180/255.0 blue:237/255.0 alpha:1]];
    self.window.rootViewController = [MapViewController new];

 

MapViewController.m//設置需要的屬性

建一個類:

 

//.h
#import 
#import 
@interface Mypoint : NSObject
//實現MKAnnotion協議必須要定義這個屬性
@property (nonatomic,readonly)CLLocationCoordinate2D coordinate;
//標題
@property (nonatomic,copy)NSString *title;

//初始化方法
- (id)initWithCoordinate:(CLLocationCoordinate2D)c andTitle:(NSString *)t;

@end

//.m
#import Mypoint.h

@implementation Mypoint
//初始化方法
- (id)initWithCoordinate:(CLLocationCoordinate2D)c andTitle:(NSString *)t{
    if (self = [super init]) {
        _coordinate = c;
        _title = t;
    }
    return self;
}
@end
