存儲圖像EXIF mata數據dictonary

Question

我想存儲圖像的EXIF數據在DictRequest。

我該怎麼做？請幫我

下面是代碼：

ALAssetRepresentation *rep = [temp defaultRepresentation]; 

StrPath = [StrPath stringByAppendingFormat:@"%d.%@",(int)timeInterval,strImageType]; 

UIImage *image = [UIImage imageWithCGImage:[rep fullResolutionImage]]; 
NSLog(@"Image width %f Image height %f",image.size.width,image.size.height); 

NSData *dataObj = nil; 
dataObj = UIImageJPEGRepresentation(image, 1.0); 

NSLog(@"Length of data %d",[dataObj length]); 
NS tring* StrFileData = [Base64 encode:dataObj]; 
NSString* strFileHash = [dataObj md5Test]; 

//---------------------------------------------------- 
NSMutableDictionary *DictRequest = [[NSMutableDictionary alloc]init]; 
[DictRequest setObject:srtprefSessionId forKey:@"SessionId"]; 
[DictRequest setObject:StrPath forKey:@"Path"]; 
[DictRequest setValue:[NSNumber numberWithBool:isTrash] forKey:@"UploadDirectlyToTrashbin"]; 
[DictRequest setObject:StrFileData forKey:@"FileData"]; 
[DictRequest setObject:strFileHash forKey:@"FileHash"]; 
[DictRequest setObject:result forKey:@"DateCreated"];

您可以[rep metadata]訪問圖像的元數據。該詞典應包含EXIF數據。通過UIImage對象無法訪問EXIF數據。
