如何在objective-c中使UIImage为NULL

问题描述

I have used the code :
UIImage *selectedImage;

then,

for (int j = 1 ; j <=b ; j++){
        id subView = [self.view viewWithTag:j];

        if ([subView isKindOfClass:[UIImageView class]]){
            ((UIImageView *)subView).image = selectedImage;

then how to make the UIImage as null value.

解决方案

Instead of making UIImage NULL set the Image as Empty Image

[UIImage imageNamed:@""]
