如何查看数组中存储的图像？

Question

I found a way to store images of UIImagePickerControllerSourceTypePhotoLibrary in an NSArray but I can not find a solution to view images in an UIImageView from the NSArray . Here is the link to store image:

Can the selected images from library be stored in an array?

Answer 1

You just need to iterate through that array...

for(UIImage *img in self.imageArray){
self.image = img;
}

Or imageView:

for(UIImageView *imgView in self.imageArray){
self.imageView = imgView;
}

Answer 2

Lets say you stored images in array :

NSArray *imageArray = @[image1, image2, image3]; //imageX are arbitrary name for images.

To view these images one by one, you need to load them and show in UIImageView:

//lets assume you have multiple buttons and all targeted to this method.
-(IBAction)buttonClicked:(UIButton *)sender{ 
    NSInteger index = sender.tag;
    //here index is the integer to load the image. 

    if(index < imageArray.count){
        self.imageView setImage: imageArray[index]; 
    }
}
