使用协议方法实现百度地图SDK的调用

使用协议方法实现百度地图的调用
首先导入百度SDK，百度SDK可以手动导入，也可以使用cocoaPods进行导入
创建一个协议方法，

#import <UIKit/UIKit.h>

@protocol IMapView <NSObject>

-(instancetype)initWithFrame:(CGRect)frame;

-(UIView *)getView;

@end

创建对象并继承自IMapView代理

#import <Foundation/Foundation.h>
#import "IMapView.h"
@interface BaiduMapView : NSObject<IMapView>

@end


#import "BaiduMapView.h"
#import <BaiduMapAPI_Map/BMKMapView.h>

@interface BaiduMapView()

@property (nonatomic,strong)BMKMapView *mapView;

@end

@implementation BaiduMapView

-(instancetype)initWithFrame:(CGRect)frame {
    self = [super init];
    if (self) {
        _mapView = [[BMKMapView alloc]initWithFrame:frame];
        _mapView.showsUserLocation = YES;
    }
    return self;
}

-(UIView *)getView {
    return _mapView;
    
}

@end

上面的方法主要是实现百度地图的展示功能

再创建一个协议方法

#import <Foundation/Foundation.h>
#import "IMapView.h"
@protocol IMapFactory <NSObject>

-(id<IMapView>)getMapView:(CGRect)frame;

@end

创建一个对象并继承自IMapFactory

#import <Foundation/Foundation.h>
#import "IMapFactory.h"
@interface BaiduMapFactory : NSObject<IMapFactory>

@end


#import "BaiduMapFactory.h"
#import <BaiduMapKit/BaiduMapAPI_Base/BMKMapManager.h>
#import "BaiduMapView.h"
@interface BaiduMapFactory()

@property (nonatomic,strong)BMKMapManager *mapManager;

@end

@implementation BaiduMapFactory

-(instancetype)init {
    self = [super init];
    if (self) {
        _mapManager = [[BMKMapManager alloc]init];
        // 如果要关注网络及授权验证事件，请设定     generalDelegate参数
        BOOL ret = [_mapManager start:@"EKwKtqQTUuFEOCdRXGDCjXRAl5vV9M3B"  generalDelegate:nil];
        if (!ret) {
            NSLog(@"manager start failed!");
        }
    }
    return self;
}

- (id<IMapView>)getMapView:(CGRect)frame {
    return [[BaiduMapView alloc]initWithFrame:frame];
}

之后再ViewController中实现暂时方法

#import "ViewController.h"
#import "BaiduMapFactory.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    id<IMapFactory> mapFactory = [[BaiduMapFactory alloc]init];
    
    id<IMapView> mapView = [mapFactory getMapView:self.view.frame];
    
    [self.view addSubview:[mapView getView]];
    // Do any additional setup after loading the view, typically from a nib.
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


@end

这样就实现了使用协议完成百度地图集成的方法，是不是很简单
