目前App的地图功能越来越普遍了，导航也是斯通见惯了，基于这一块的可通用性，我简单封装了一下导航的功能。效果如下(点图可以下载该APP)。

点击导航，显示你手机上安装的地图列表

功能实现，分两步
1. 获取地图列表
- (NSArray *)getInstalledMapAppWithEndLocation:(CLLocationCoordinate2D)endLocation
2. 进行导航
- (void)gotoNavigateWithLongitude:(double)longitude latitude:(double)latitude placeName:(NSString *)placeName
具体代码如下
#import
// 地图（定位／导航）
#import
#import
#import
@interface MapNavigationTool : NSObject
/**
导航
@param longitude 经度
@param latitude 纬度
@param placeName 地点名称
*/
- (void)gotoNavigateWithLongitude:(double)longitude latitude:(double)latitude placeName:(NSString *)placeName;
@end
#import "MapNavigationTool.h"
#import "CustomActionSheet.h"
#import "JZLocationConverter.h"
@interface MapNavigationTool()
@property(strong,nonatomic)NSString *placeName;
/**
用于存储当前手机中可用的地图
*/
@property(strong,nonatomic)NSArray *maps;
/**
要导航位置的坐标
*/
@property(assign,nonatomic)CLLocationCoordinate2D locationCoordinate2D;
@end
@implementation MapNavigationTool
/**
导航
@param longitude 经度
@param latitude 纬度
*/
- (void)gotoNavigateWithLongitude:(double)longitude latitude:(double)latitude placeName:(NSString *)placeName{
self.placeName = placeName;
self.locationCoordinate2D = CLLocationCoordinate2DMake(latitude,longitude);
self.maps = [self getInstalledMapAppWithEndLocation:self.locationCoordinate2D];
NSMutableArray *titlesArr = [NSMutableArray array];
for (int i = 0; i < self.maps.count; i++) {
NSDictionary *dict = [self.maps objectAtIndex:i];
NSString *temp = [dict objectForKey:@"title"];
[titlesArr addObject:temp];
}
CustomActionSheet *mySheet = [[CustomActionSheet alloc] initWithTitle:nil otherButtonTitles:titlesArr];
mySheet.delegate = self;
[mySheet show];
}
/**

即：再Info.plist 文件中添加元素

常见错误
- -canOpenURL: failed for URL: "iosamap://" - error: "This app is not allowed to query for scheme iosamap"
权限问题，iOS9以后苹果自带的地图以外，使用其他地图需要添加白名单
即：在Info.plist 文件中添加元素
LSApplicationQueriesSchemes Array 数组类型
NSString iosamap
NSString comgooglemaps
NSString baidumap
NSString qqmap

- -canOpenURL: failed for URL: "comgooglemaps://" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"
因为你手机上没有安装该应用。
