iOS中 百度地图详解 韩俊强的博文

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:

指示根视图:

    [[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//设置需要的属性

#import <MapKit/MapKit.h>
#import "Mypoint.h"

    //放大到标注的位置
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(location, 0.01, 0.01);
    [self.mapView setRegion:region];
}

建一个类:

//.h
#import <Foundation/Foundation.h>
#import <MapKit/MapKit.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;

@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
