iOS 把图片保存到相册,并获取图片文件名的实例

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {  UIImageWriteToSavedPhotosAlbum(image,self,@selector(image:didFinishSavingWithError:contextInfo:),NULL); }}- (void)image:(UIImage*)image didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo{ if (error) {  DLog(@"图片保存失败！"); }else{  DLog(@"图片保存成功！"); }}此方法可以把其他来源的图片也可保存到相册 //当image从相机中获取的时候存入相册中 //保存方法1//  UIImageWriteToSavedPhotosAlbum(img.image,self,@selector(image:didFinishSavingWithError:contextInfo:),NULL);//   imageData = nil;    WEAKSELF  //保存方法2同时获取保存的相片文件名  __blockALAssetsLibrary *lib = [[ALAssetsLibraryalloc] init];  [lib writeImageToSavedPhotosAlbum:img.image.CGImagemetadata:nilcompletionBlock:^(NSURL *assetURL,NSError *error) {      ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *imageAsset)   {    ALAssetRepresentation *imageRep = [imageAssetdefaultRepresentation];    weakSelf.imageName = [NSStringstringWithFormat:@"%@",[imageRepfilename]];    NSLog(@"[imageRep filename 1] : %@", [imageRepfilename]);    DBLog(@"self.addressImageName照相0 = %@",weakSelf.imageName);    commitBlock(img.image,UIImageJPEGRepresentation(img.image,0.5),self.imageName);   };   ALAssetsLibrary* assetslibrary = [[ALAssetsLibraryalloc] init];   [assetslibrary assetForURL:assetURLresultBlock:resultblock failureBlock:nil];      NSLog(@"assetURL = %@, error = %@", assetURL, error);   lib = nil;     }];   }];
