1. 麦克风权限
- 单存检测是否有麦克风权限，并不会弹出是否允许弹出权限提示框
#import <AVFoundation/AVFoundation.h>
/**
判断当前是有语音权限,但是不会弹出是否允许弹出权限
（需要在info中配置）Privacy - Microphone Usage Description 允许**访问您的语音，来用于**功能？
@return YES:有权限，NO:没权限
*/
- (BOOL)JX_Device_Permission_AudioAuth {
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
if (authStatus == AVAuthorizationStatusDenied || authStatus == AVAuthorizationStatusRestricted) {
return NO;
}
return YES;
}
- 检测是否有权限，如果没有授权过，会弹出是否允许提示框
#import <AVFoundation/AVFoundation.h>
/**
判断当前是有语音权限,会弹出是否允许弹出权限
（需要在info中配置）Privacy - Microphone Usage Description 允许**访问您的语音，来用于**功能？
*/
- (void)JX_Device_Permission_Check_AudioAuth {
AVAudioSession *session = [AVAudioSession sharedInstance];
if ([session respondsToSelector:@selector(requestRecordPermission:)]){
[session performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {
// do something
}];
}
}
2. 访问相册权限
- 检测是否有访问相册权限，并不会弹出是否允许访问相册权限提示框
#import <Photos/Photos.h>
#import <AssetsLibrary/AssetsLibrary.h>
/**
判断相册权限开关,但是不会弹出是否允许弹出权限
(需要在info中配置)Privacy - Photo Library Additions Usage Description 允许**访问您的相册,来用于**功能
@return YES:有权限，NO:没权限
*/
- (BOOL)JX_Device_Permission_PhotoLibraryAuth {
if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
PHAuthorizationStatus authStatus = [PHPhotoLibrary authorizationStatus];
if(authStatus == PHAuthorizationStatusDenied || authStatus == PHAuthorizationStatusRestricted) {
return NO;
}
} else if ([[UIDevice currentDevice].systemVersion floatValue] >= 6.0 && [[UIDevice currentDevice].systemVersion floatValue] < 8.0) {
ALAuthorizationStatus authStatus = [ALAssetsLibrary authorizationStatus];
if(authStatus == ALAuthorizationStatusDenied || authStatus == ALAuthorizationStatusRestricted) {
return NO;
}
}
return YES;
}
- 检测是否有权限，如果没有授权过，会弹出是否允许提示框
#import <Photos/Photos.h>
/**
判断相册权限开关,会弹出是否允许弹出权限
(需要在info中配置)Privacy - Photo Library Additions Usage Description 允许**访问您的相册,来用于**功能
*/
- (void)JX_Device_Permission_Check_PhotoLibraryAuth{
BOOL auth = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary];
if (!auth) return;
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) { //弹出访问权限提示框
if (status == PHAuthorizationStatusAuthorized) { // 有权限
dispatch_async(dispatch_get_main_queue(),^{
// do something
// 一般操作
self.imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:self.imagePickerController animated:YES completion:nil];
});
} else {
dispatch_async(dispatch_get_main_queue(),^{ // 无权限
// do something
});
}
}];
}
3. 访问相机权限
- 检测是否有相机拍照权限，并不会弹出是否允许提示框
#import <AVFoundation/AVFoundation.h>
/**
判断相机权限开关,但是不会弹出是否允许弹出权限
(需要在info中配置)Privacy - Camera Usage Description 允许**访问您的相机,来用于**功能
@return YES:有权限，NO:没权限
*/
- (BOOL)JX_Device_Permission_CameraAuth {
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
if (authStatus == AVAuthorizationStatusDenied || authStatus == AVAuthorizationStatusRestricted) {
return NO;
}
return YES;
}
- 检测是否有过授权，如果没有授权过，会弹出是否允许提示框
#import <AVFoundation/AVFoundation.h>
/**
判断相机权限开关,会弹出是否允许弹出权限
(需要在info中配置)Privacy - Camera Usage Description 允许**访问您的相机,来用于**功能
*/
- (void)JX_Device_Permission_Check_CameraAuth {
BOOL auth = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
if (!auth) permission(NO);
NSString *mediaType = AVMediaTypeVideo;//读取媒体类型
[AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) {
dispatch_async(dispatch_get_main_queue(),^{
if (granted) { // 授权成功
// do something
// 一般会做的操作，跳转到系统的相机
self.imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:self.imagePickerController animated:YES completion:nil];
} else { // 拒绝授权
// do something
}
});
}];
}
4. 推送权限(远程、本地)
- 检测是否有推送权限，并不会弹出是否允许提示框
/**
推送权限开关
@return YES:有权限，NO:没权限
*/
- (BOOL)JX_Device_Permission_NotificationAuth {
if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0f) {
UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
if (UIUserNotificationTypeNone == setting.types) {
return NO;
}
} else {
UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if(UIRemoteNotificationTypeNone == type){
return NO;
}
}
return YES;
}
- 检测是否有过授权，如果没有授权过，会弹出是否允许提示框
说明：这里仅仅是检测是否授权过，弹出提示框操作。至于远程注册一些流程请参见另一篇博客。iOS 通知详解(远程通知、本地通知)
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif
/**
判断通知权限开关,会弹出是否允许弹出权限(远程、本地)
*/
- (void)JX_Device_Permission_Check_NotificationAuth {
if ([[UIDevice currentDevice].systemVersion floatValue] >= 10.0) {
[[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
dispatch_async(dispatch_get_main_queue(), ^{
// do something
// 对granted 进行判断，是否允许权限
});
}];
} else if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];
BOOL auth = [self JX_Device_Permission_NotificationAuth];
// 对auth 进行判断，是否允许权限
}
}
