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 miniXcode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 NSPhotoLibraryUsageDescriptionPrivacy - 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//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);
