Camera(相机)常见属性检测

1.判断相机是否可用

  • (BOOL) isCameravail{
    return [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
    }
    2.赏光灯是否可用
  • (BOOL) isCameraFlashavail{
    //前置摄像头
    return [UIImagePickerController isFlashAvailableForCameraDevice:
    UIImagePickerControllerCameraDeviceFront];
    //后置摄像头
    return [UIImagePickerController isFlashAvailableForCameraDevice:UIImagePickerControllerCameraDeviceRear];
    }
    3.摄像头是否可用
  • (BOOL) isCameraavail{
    //前置摄像头
    return [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront];
    //后置摄像头
    return [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear];
    }
    4.判断当前的摄像头支持媒体类型照片OR录像
    //拍照
    if([self cameraSupportMedia:(_bridge NSString*) KUTTypeImage]){

}
//录像
if([self cameraSupportMedia:(_bridge NSString*) KUTTypeMovie]){

}

  • (BOOL) cameraSupportMedia: (NSString )paraMediaType{
    NSArray
    avaiableMedia = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
    for (NSString *item in avaiableMedia) {
    if ([item isEqualToString:paraMediaType]) {
    return true;
    }
    }

    return false;
    }
