我拍摄了 1 张高质量图像并将其存储到

 UIImage *image = [[UIImage alloc] initWithData:imageData];
 NSArray *docDirs = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSAllDomainsMask, YES);
 NSString *docDir = [docDirs objectAtIndex:0];
 BOOL success = [UIImagePNGRepresentation(image) writeToFile:[docDir stringByAppendingPathComponent:@"test11.png"] atomically:YES];

我可以从 xcode Organizer 中看到的某个位置，图像分辨率非常高。 尺寸：2592 × 1936 ... 大小 6.1MB

我的问题是如何在 iPhone 库中存储高质量图像。我严格不允许存储压缩图像。我必须仅存储高清高质量图像。

请不要使用scaleAndRotateImage函数回复，因为它会压缩图像。

原文

I have taken 1 high quality image and stored it to some place

 UIImage *image = [[UIImage alloc] initWithData:imageData];
 NSArray *docDirs = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSAllDomainsMask, YES);
 NSString *docDir = [docDirs objectAtIndex:0];
 BOOL success = [UIImagePNGRepresentation(image) writeToFile:[docDir stringByAppendingPathComponent:@"test11.png"] atomically:YES];

I can see from xcode organizer the image resolution is very high quality.
Dimension: 2592 × 1936 ... size 6.1MB

My problem is how can I store high quality image in iphone Library. I am strictly not allowed to store compressed image. I have to store only HD high quality image.

Please do not reply with scaleAndRotateImage functions because it will compress image.
