iOS获取照片EXIF信息

废话不多说，直接上代码。

let options = PHImageRequestOptions()
options.version = PHImageRequestOptionsVersion.current;
options.deliveryMode = PHImageRequestOptionsDeliveryMode.highQualityFormat;
options.isSynchronous = true;
let phImageManager = PHImageManager.default()
phImageManager.requestImageData(for: photoAsset,
                                options: options,
                                resultHandler:{
                                    (data: Data?, 
                                     dataUti: String?, 
                                     orientaion: UIImageOrientation, 
                                     info: [AnyHashable : Any]?) in
                                    let imageData: NSData = data! as NSData
                                    if let imageSource = CGImageSourceCreateWithData(imageData, nil) {
                                        let imageProperties = CGImageSourceCopyPropertiesAtIndex(imageSource, 0, nil)! as NSDictionary
                                        print(imageProperties)
                                    }                                    
                                })
