如何查看數組中存儲的圖像？

Question

我找到了一種將UIImagePickerControllerSourceTypePhotoLibrary的圖像存儲在NSArray中的方法，但我找不到解決方案來查看NSArray中的UIImageView中的圖像。這裏是鏈接到店面形象：

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

Answer 1

你只需要通過數組迭代...

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

或者ImageView的：

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

Answer 2

可以說你存儲的圖像排列：

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

要逐個查看這些圖片，你需要加載它們和秀的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]; 
    } 
}
