iOS 調取本地地圖以及三方地圖

地圖在我們 App 開發中已經算是一項比較基本的功能了,但是有些時候不需要我們去集成地圖,而是通過調取本地地圖來實現定位,我上網查了下,完成的能跑通的調用本地地圖的 demo 少之又少,於是就試着自己總結了一下

首先,我們需要導入兩個系統庫文件分別是MapKit.framework,CoreLocation.framework,然後在 plist 文件裏添加如下字段

<key>LSApplicationQueriesSchemes</key>
	<array>
		<string>baidumap</string>
		<string>iosamap</string>
		<string>comgooglemaps</string>
	</array>

因爲我不需要從地圖在跳回到 App 所以URL Types 那也就沒做添加

下面是. m 實現的代碼

#import "ViewController.h"

@import CoreLocation;
@import MapKit;


@interface ViewController ()

@property (nonatomic, strong) UIButton *btnSheet;

@property (nonatomic, strong) NSString *urlScheme;
@property (nonatomic, strong) NSString *appName;
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    self.btnSheet = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    self.btnSheet.frame = CGRectMake(0, 0, 100, 50);
    self.btnSheet.center = self.view.center;
    [self.btnSheet setTitle:@"show sheet" forState:UIControlStateNormal];
    [self.btnSheet addTarget:self action:@selector(actionSheet) forControlEvents:UIControlEventTouchUpInside];
    
    [self.view addSubview:self.btnSheet];
    
    
    self.urlScheme = @"demoURI://";
    self.appName = @"demoURI";
    //目標的經緯度(由後臺返給我們)
    self.coordinate = CLLocationCoordinate2DMake(0,0);
}
