从库中选择的图像可以存储在数组中吗? [英] Can the selected images from library be stored in an array?

问题描述

我在相机和库上构建了一个示例项目.现在，我的问题是我可以将从库中选择的图像存储到数组中吗?我正在使用此代码.

I have built a sample project on camera and library. Now, my question is can I store the images that I am selecting from library into an array? I am using this code.

UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
[self.arrImages addObject:chosenImage];

现在通过放置断点，我开始知道，即使在我多次选择图像之后，我的数组中也始终存储 1object.

Now by placing breakpoints, I came to know that, in my array always 1object is storing even after I chosen images for more than one times.

谁能告诉我我该怎么做?

Can anyone give my any idea how can I do it?

非常感谢任何帮助.

推荐答案

试试这个.

-(void)viewDidLoad {

//declare before NSMutableArray *_mutableArray;
_mutableArray = [[NSMutableArray alloc] init];
}

....

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
 //dismiss UIImagePickerController
[picker dismissViewControllerAnimated:YES completion:Nil];

//take image from anywhere
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

//store image into NSMutableArray
[_mutableArray addObject:image];


}
