下面是.m文件

里面引入了很多库文件，也不是所用项目都会用到的，用不到的注掉就好。

#import        //位置权限
#import          //通讯录权限

#import "AppDelegate.h"

#define kAPPName [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleName"]

}

最后有些时会遇到不弹出权限提示，或需要在提示框增加详细描述的时候，需要手动在info.plist加一些字段。

NSLocationWhenInUseUsageDescription    位置权限 使用期间 状态

NSLocationAlwaysUsageDescription    位置权限 始终 状态

下面这些我并没有都试，所以也不知道是否正确....

NSLocationUsageDescription    用于访问位置权限

NSCalendarsUsageDescription    用于访问日历权限

NSContactsUsageDescription    用于访问联络人

NSPhotoLibraryUsageDescription    用于访问相册

NSRemindersUsageDescription    用于访问提醒
