Loop through UIImageViews - Objective C

I have some UIImageViews in an array and want to loop through them to set an image, but I don't know how.

If I have one ImageView, imgv, then I do this:

self.imgv.image =

But how do I behave with many UIImageViews in a loop? I can't do the following:

for(int i = 0; i < [imageViewArray count]; i++)
{
  self.i.image =
}

If you need to set same image to all image views in the array then simply use,

[imageViewArray makeObjectsPerformSelector:@selector(setImage:) withObject:image];

If you need to set different images then you have to loop through the array like most of the answer have mentioned.

Hope that helps!

Try this

for(UIImageView *imgVw in imageViewArray)
{
    imgVw.image = ...;
}

for - in is used to iterate through all the element of an array.

You use the index in the loop to get an item out of the array:

for(int i = 0; i < [imageViewArray count]; i++)
{
    UIImageView *imageView = imageViewArray[i];
    imageView.image = ...;
}

or, you use a for in loop:

for (UIImageView *imageView in imageViewArray) 
{
    imageView.image = ...;
}

for(int i = 0; i < [imageViewArray count]; i++)
{
   UIImageView *tempImageView = [imageViewArray objectAtIndex:i];
   tempImageView.image=image;

}
