本文介绍如何在iOS应用中利用UIImageWriteToSavedPhotosAlbum方法将图片保存到用户的相册，包括初始化数组存储图片、获取图片并加入数组、遍历数组并调用保存方法。

将图片保存在一个数组中，通过UIImageWriteToSavedPhotosAlbum进行保存

    //in the .h file put:

NSMutableArray *myPhotoArray;


///then in the .m

- (void) viewDidLoad {

 myPhotoArray = [[NSMutableArray alloc]init];



}

//However Your getting images

- (void) someOtherMethod { 

 UIImage *someImage = [your prefered method of using this];
[myPhotoArray addObject:someImage];

}

-(void) saveMePlease {

//Loop through the array here
for (int i=0:i<[myPhotoArray count]:i++){
         NSString *file = [myPhotoArray objectAtIndex:i];
         NSString *path = [get the path of the image like you would in DOCS FOLDER or whatever];
         NSString *imagePath = [path stringByAppendingString:file];
         UIImage *image = [[[UIImage alloc] initWithContentsOfFile:imagePath]autorelease];

         //Now it will do this for each photo in the array
         UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
        }
}
