所以这个对你来说应该很简单。 我很难保存编辑UIImage(只是水平翻转)到同一个文件。相反,它会创建一个新的。将编辑好的UIImage文件保存到同一个文件
代码:
// Get current photo
id<MWPhoto> currentPhoto = [self photoAtIndex:_currentPageIndex];
// Get current image object from photo
UIImage *currentImage = [self imageForPhoto:(currentPhoto)];
// Mirror it
currentImage = [UIImage imageWithCGImage:currentImage.CGImage
scale:currentImage.scale
orientation:UIImageOrientationUpMirrored];
// Get NSData from image
NSData *imageData = UIImageJPEGRepresentation(currentImage, 1);
// Create ALAsssetsLibrary to save data to photos
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeImageDataToSavedPhotosAlbum:imageData metadata:nil completionBlock:^(NSURL *assetURL, NSError *error) {
if (error != nil) {
NSLog(@"There was an error saving image");
} else {
NSLog(@"Image should be saved");
}
}];
任何想法,我做错了什么?
与UIImageWriteToSavedPhotosAlbum(currentImage, nil, nil, nil);
,但还是一样也试过。
