带有 UIImagePickers 的多个 UIImageViews

Question

我有 3 个 UIImageViews 我想为其加载图像。 对于 1 张图像，这不是问题，但如何缩放到 3 张？ 下面的代码就是我现在所拥有的。

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

}


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];    
UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage];
[my_image_1 setImage:image forState:UIControlStateNormal];

}

Answer 1

你看过this或this吗？他们似乎指向这个resource。

根据您的评论，我建议您在您的班级中声明一个 ivar imageViewToSet 并在问题中更改您的方法，如下所示，

-(IBAction) getPhoto:(id) sender {
    // Add code to identify the sender(button) via tags or outlets and set imageViewToSet to the mapped imageView through a switch or if statement.
    UIImagePickerController * picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    [self presentModalViewController:picker animated:YES];
}


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissModalViewControllerAnimated:YES];    
    imageViewToSet.image = [info objectForKey:UIImagePickerControllerOriginalImage];
}
