ios - 将相册中的图像分配给变量 Objective-c

Question

我正在使用以下代码从相册中获取图像:

-(IBAction) getPhoto:(id) sender {
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;

picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

[self presentViewController:picker animated:YES completion:nil];}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:nil];
imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];}

谁能帮我把这张图片赋值给一个变量？我想稍后使用 stackblur 对其进行模糊处理:

UIImage *newIma=[oldIma stackBlur:radius];

提前致谢!

Answer 1

在获取用户选择的图像时设置 UIImage。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:YES completion:nil];
    // Create the UIImage in your @implementation and set it here
    myImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    myImageView.image = myImage;
}
