?case PHAuthorizationStatusAuthorized:? ? ? ?
?NSLog(@"Authorized");? ? ? ? ? ? ?
?break;?

NSLog(@"Authorized");?
?}else{? ? ? ??
NSLog(@"Denied or Restricted");?

相機和麥克風權(quán)限
導入頭文件@import AVFoundation;
檢查是否有相機或麥克風權(quán)限
AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];//相機權(quán)限
AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];//麥克風權(quán)限
switch (AVstatus) {??

if (granted) {? ??
? NSLog(@"Authorized");?
?}else{? ??
? NSLog(@"Denied or Restricted");?
?}}];
定位權(quán)限
導入頭文件@import CoreLocation;
由于iOS8.0之后定位方法的改變，需要在info.plist中進行配置；
檢查是否有定位權(quán)限
BOOL isLocation = [CLLocationManager locationServicesEnabled];
if (!isLocation) {?
?NSLog(@"not turn on the location");
}
CLAuthorizationStatus CLstatus = [CLLocationManager authorizationStatus];
switch (CLstatus) {??
case kCLAuthorizationStatusAuthorizedAlways: ? ? ??
NSLog(@"Always Authorized");? ? ? ? ? ? ?
?break;??
case kCLAuthorizationStatusAuthorizedWhenInUse:? ? ? ?
?NSLog(@"AuthorizedWhenInUse");? ? ? ? ? ? ?
?break;?
?case kCLAuthorizationStatusDenied:? ? ? ??
NSLog(@"Denied");? ? ? ? ? ?
?? break;? ?
?case kCLAuthorizationStatusNotDetermined:? ? ??
? NSLog(@"not Determined");? ? ? ? ??
? ? break;? ?
?case kCLAuthorizationStatusRestricted:? ? ??
? NSLog(@"Restricted");? ? ? ? ? ? ?
?break;??
? default:? ? ? ? ??
? ? break;}
獲取定位權(quán)限
CLLocationManager *manager = [[CLLocationManager alloc] init];
[manager requestAlwaysAuthorization];//一直獲取定位信息
[manager requestWhenInUseAuthorization];//使用的時候獲取定位信息
在代理方法中查看權(quán)限是否改變
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{?
switch (status) {
? case kCLAuthorizationStatusAuthorizedAlways:? ? ??
? NSLog(@"Always Authorized");? ? ? ? ? ? ?
?break;? ??
case kCLAuthorizationStatusAuthorizedWhenInUse:? ? ? ?
?NSLog(@"AuthorizedWhenInUse");? ? ? ? ? ??
? break;? ?
?case kCLAuthorizationStatusDenied:? ? ? ? ? ? ?
?NSLog(@"Denied");? ? ? ? ? ? ?
?break;? ?
?case kCLAuthorizationStatusNotDetermined:? ? ??
? NSLog(@"not Determined");? ? ? ? ? ? ?
?break;? ?
?case kCLAuthorizationStatusRestricted:? ? ??
? NSLog(@"Restricted");? ? ? ? ? ??
? break;? ??
default:? ? ??
? break;?
?}}
推送權(quán)限
檢查是否有通訊權(quán)限
UIUserNotificationSettings *settings = [[UIApplication sharedApplication] currentUserNotificationSettings];
switch (settings.types) {?
?case UIUserNotificationTypeNone:? ? ? ?
?NSLog(@"None");? ? ? ? ? ??
? break;? ??
case UIUserNotificationTypeAlert:? ? ??
? NSLog(@"Alert Notification");? ? ? ? ? ??
? break;?
?case UIUserNotificationTypeBadge:? ? ?
?? NSLog(@"Badge Notification");? ? ? ? ? ?
?? break;? ??
case UIUserNotificationTypeSound:? ? ??
? NSLog(@"sound Notification'");? ? ? ? ? ??
? break;??
? default:? ? ? ? ? ? ?
?break;
}
獲取推送權(quán)限
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];
通訊錄權(quán)限
導入頭文件 @import AddressBook;
檢查是否有通訊錄權(quán)限
ABAuthorizationStatus ABstatus = ABAddressBookGetAuthorizationStatus();
switch (ABstatus) {??
?case kABAuthorizationStatusAuthorized:? ? ? ? ? ??
? NSLog(@"Authorized");? ? ? ? ? ??
? break;? ? case kABAuthorizationStatusDenied:? ? ??
? NSLog(@"Denied'");? ? ? ? ? ??
? break;? ??
?case kABAuthorizationStatusNotDetermined:? ? ? ?
?NSLog(@"not Determined");? ? ? ? ? ?
?? break;? ?
?case kABAuthorizationStatusRestricted:? ? ? ?
?NSLog(@"Restricted");? ? ? ? ? ??
? break;? ?
?default:? ? ? ? ? ?
?? break;}
獲取通訊錄權(quán)限
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {?
?if (granted) {? ? ? ?
?NSLog(@"Authorized");? ? ? ?
?CFRelease(addressBook);?
?}else{? ? ? ??
NSLog(@"Denied or Restricted");?
?}
});
日歷、備忘錄權(quán)限
導入頭文件
檢查是否有日歷或者備忘錄權(quán)限
typedef NS_ENUM(NSUInteger, EKEntityType) {
EKEntityTypeEvent,//日歷
EKEntityTypeReminder //備忘
};
EKAuthorizationStatus EKstatus = [EKEventStore? authorizationStatusForEntityType:EKEntityTypeEvent];
switch (EKstatus) {??
case EKAuthorizationStatusAuthorized:? ? ? ?
?NSLog(@"Authorized");? ? ? ? ??
? ? break;??
? case EKAuthorizationStatusDenied:? ? ? ??
NSLog(@"Denied'");? ? ? ? ? ?
?? break;??
? case EKAuthorizationStatusNotDetermined:? ? ? ?
?NSLog(@"not Determined");? ? ? ? ? ??
? break; ??
case EKAuthorizationStatusRestricted:? ? ? ?
?NSLog(@"Restricted");? ? ? ? ? ? ?
?break;??
?default:? ? ??
? break;
}
獲取日歷或備忘錄權(quán)限
EKEventStore *store = [[EKEventStore alloc]init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError * _Nullable error) {?
?if (granted) {? ? ? ?
?NSLog(@"Authorized");?
?}else{? ? ? ??
NSLog(@"Denied or Restricted");??
}
}];
最后一點
素有獲取權(quán)限的方法，多用于用戶第一次操作應(yīng)用，iOS 8.0之后，將這些設(shè)置都整合在一起，并且可以開啟或關(guān)閉相應(yīng)的權(quán)限。所有的權(quán)限都可以通過下面的方法打開：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
