ios 判断用户是否开启权限---并跳转设置

ios 判断用户是否开启权限---并跳转“系统设置”

1.判断访问相册或相机权限是否开启

2.检测是否开启定位

后面将持续更新

只有在应用请求过位置权限或者通知权限的时候，才会跳进自己app里面的设置呢。不然直接跳到系统设置界面

//打开app定位设置

NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];

if([[UIApplication sharedApplication] canOpenURL:settingsURL]) {

[[UIApplication sharedApplication] openURL:settingsURL];

}

工具/原料

Mac / Mac mini
Xcode

方法/步骤

1. =====判断访问相册或相机权限是否开启====

//在info.plist 里面设置

NSCameraUsageDescription

Privacy - Camera Usage Description App需要您的同意,才能访问相机

NSPhotoLibraryUsageDescription

Privacy - Photo Library Usage Description   App需要您的同意,才能访问相册

科普：

//=================相册=======================

//相册权限判断需要引入框架

#import <Photos/PHPhotoLibrary.h> //相册

===PHAuthorizationStatus===相册权限状态判断

在8.0系统以后，新加入了Photos.framework框架，我们可以利用框架中的PHAuthorizationStatus进行相册权限状态判断。

==判断是否开启相册权限的4中状态

typedef NS_ENUM(NSInteger,PHAuthorizationStatus) {

//==1. 用户还没有关于这个应用程序做出了选择

PHAuthorizationStatusNotDetermined = 0,

//==2. 这个应用程序未被授权访问图片数据。用户不能更改该应用程序的状态,可能是由于活动的限制,如家长控制到位。

PHAuthorizationStatusRestricted,

//==3. 用户已经明确否认了这个应用程序访问图片数据

PHAuthorizationStatusDenied,

//==4. 用户授权此应用程序访问图片数据

PHAuthorizationStatusAuthorized

}PHOTOS_AVAILABLE_IOS_TVOS(8_0, 10_0);

//========================相机=====================

//相册权限判断需要引入框架

#import <AVFoundation/AVCaptureDevice.h>#import <AVFoundation/AVMediaFormat.h>

//=======AVAuthorizationStatus====

==判断是否开启相机权限的4中状态

typedef NS_ENUM(NSInteger, AVAuthorizationStatus) {



//1. 表明用户尚未选择关于客户端是否可以访问硬件

AVAuthorizationStatusNotDetermined = 0,



  //2. 客户端未被授权访问硬件的媒体类型。用户不能改变客户机的状态,可能由于活跃的限制,如家长控制

AVAuthorizationStatusRestricted,



//3. 明确拒绝用户访问硬件支持的媒体类型的客户

AVAuthorizationStatusDenied,



//4. 客户端授权访问硬件支持的媒体类型

AVAuthorizationStatusAuthorized

} NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;

=================使用====================

//选择从相册获取图片

//判断状态如果已经授权则从相册选取相片

如果没有授权则跳转到授权设置界面

//选择从相机获取图片

//判断状态如果已经授权则打开摄像头

如果没有授权则跳转到授权设置界面

//引入下面的框架

//相册权限判断需要引入框架

#import <Photos/PHPhotoLibrary.h> //相册

//相册权限判断需要引入框架

#import <AVFoundation/AVCaptureDevice.h>#import <AVFoundation/AVMediaFormat.h>

【注意】控制器要遵循的协议

遵循协议 <CLLocationManagerDelegate>

//=========CLAuthorizationStatus=========

kCLAuthorizationStatusNotDetermined = 0,

//定位服务授权状态是受限制的。可能是由于活动限制定位服务，用户不能改变。这个状态可能不是用户拒绝的定位服务

kCLAuthorizationStatusRestricted,

//定位服务授权状态已经被用户明确禁止，或者在设置里的定位服务中关闭

kCLAuthorizationStatusDenied,

//定位服务授权状态已经被用户允许在任何状态下获取位置信息。包括监测区域、访问区域、或者在有显著的位置变化的时候

kCLAuthorizationStatusAuthorizedAlways NS_ENUM_AVAILABLE(10_12, 8_0),

//定位服务授权状态仅被允许在使用应用程序的时候

kCLAuthorizationStatusAuthorizedWhenInUse NS_ENUM_AVAILABLE(NA, 8_0),
