人脸识别，从iOS7开始，系统就集成了！方法也比较简单！dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{    CIImage *image = [CIImage imageWithCGImage:self.imageView.image.CGImage];
    CIDetector *detector = [CIDetector detectorOfType:CIDetectorTypeFace
                                              context:nil
                                              options:@{CIDetectorAccuracy: CIDetectorAccuracyHigh}];
    
    NSDictionary *options = @{
                              CIDetectorSmile: @(YES),
                              CIDetectorEyeBlink: @(YES),
                              };
    
    NSArray *features = [detector featuresInImage:image options:options];
    
    NSMutableString *resultStr = @"DETECTED FACES:\n\n".mutableCopy;
    
    for(CIFaceFeature *feature in features)
    {
        [resultStr appendFormat:@"bounds:%@\n", NSStringFromCGRect(feature.bounds)];
        [resultStr appendFormat:@"hasSmile: %@\n\n", feature.hasSmile ? @"YES" : @"NO"];
        //        NSLog(@"faceAngle: %@", feature.hasFaceAngle ? @(feature.faceAngle) : @"NONE");
        //        NSLog(@"leftEyeClosed: %@", feature.leftEyeClosed ? @"YES" : @"NO");
        //        NSLog(@"rightEyeClosed: %@", feature.rightEyeClosed ? @"YES" : @"NO");
    }
    
    dispatch_async(dispatch_get_main_queue(), ^{
        
        self.textView.text = resultStr;
    });
});
