联网权限
#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTCellularData.h>
应用启动后，检测应用中是否有联网权限
CTCellularData *cellularData = [[CTCellularData alloc]init];
cellularData.cellularDataRestrictionDidUpdateNotifier = ^(CTCellularDataRestrictedState state){
//获取联网状态
switch (state) {
case kCTCellularDataRestricted:
NSLog(@"Restricrted");
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView*alert = [[UIAlertViewalloc]initWithTitle:@"已为“XXX”关闭蜂窝移动数据"
message:@"您可以在系统“设置”中为此应用打开蜂窝移动数据。"
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alertshow];
[alertrelease];
});
break;
case kCTCellularDataNotRestricted:
NSLog(@"Not Restricted");
break;
case kCTCellularDataRestrictedStateUnknown:
NSLog(@"Unknown");
break;
default:
break; };};
查询应用是否有联网功能
CTCellularData *cellularData = [[CTCellularData alloc]init];
CTCellularDataRestrictedState state = cellularData.restrictedState;
switch (state) {
case kCTCellularDataRestricted:
NSLog(@"Restricrted");
break;
case kCTCellularDataNotRestricted:
NSLog(@"Not Restricted");
break;
case kCTCellularDataRestrictedStateUnknown:
NSLog(@"Unknown");
break;
default:
break;}
相册权限--iOS 9.0之前
导入头文件@import AssetsLibrary;
检查是否有相册权限
PHAuthorizationStatus photoAuthorStatus = [PHPhotoLibrary authorizationStatus];
switch (photoAuthorStatus) {
case PHAuthorizationStatusAuthorized:
NSLog(@"Authorized");
break;
case PHAuthorizationStatusDenied:
NSLog(@"Denied");
break; case PHAuthorizationStatusNotDetermined:
NSLog(@"not Determined");
break;
case PHAuthorizationStatusRestricted:
NSLog(@"Restricted");
break;
default:
break;}
获取相册权限
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
if (status == PHAuthorizationStatusAuthorized) {
NSLog(@"Authorized");
}else{
NSLog(@"Denied or Restricted");
} }];
相机和麦克风权限
导入头文件@import AVFoundation;
检查是否有相机或麦克风权限
AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];//相机权限
AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];//麦克风权限
switch (AVstatus) {
case AVAuthorizationStatusAuthorized:
NSLog(@"Authorized");
break;
case AVAuthorizationStatusDenied:
NSLog(@"Denied");
break;
case AVAuthorizationStatusNotDetermined:
NSLog(@"not Determined");
break; case AVAuthorizationStatusRestricted:
NSLog(@"Restricted");
break;
default:
break;}
获取相机或麦克风权限
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {//相机权限
if (granted) {
NSLog(@"Authorized");
}else{
NSLog(@"Denied or Restricted");
}}];
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {//麦克风权限
if (granted) {
NSLog(@"Authorized");
}else{
NSLog(@"Denied or Restricted");
}}];
定位权限
导入头文件@import CoreLocation;
由于iOS8.0之后定位方法的改变，需要在info.plist中进行配置；
检查是否有定位权限
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;}
获取定位权限
CLLocationManager *manager = [[CLLocationManager alloc] init];
[manager requestAlwaysAuthorization];//一直获取定位信息
[manager requestWhenInUseAuthorization];//使用的时候获取定位信息
在代理方法中查看权限是否改变
- (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;
}}
推送权限
检查是否有通讯权限
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;
}
获取推送权限
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];
通讯录权限
导入头文件 @import AddressBook;
检查是否有通讯录权限
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;}
获取通讯录权限
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
if (granted) {
NSLog(@"Authorized");
CFRelease(addressBook);
}else{
NSLog(@"Denied or Restricted");
}
});
日历、备忘录权限
导入头文件
检查是否有日历或者备忘录权限
typedef NS_ENUM(NSUInteger, EKEntityType) {
EKEntityTypeEvent,//日历
EKEntityTypeReminder //备忘
};
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;
}
获取日历或备忘录权限
EKEventStore *store = [[EKEventStore alloc]init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError * _Nullable error) {
if (granted) {
NSLog(@"Authorized");
}else{
NSLog(@"Denied or Restricted");
}
}];
最后一点
素有获取权限的方法，多用于用户第一次操作应用，iOS 8.0之后，将这些设置都整合在一起，并且可以开启或关闭相应的权限。所有的权限都可以通过下面的方法打开：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
