looping through uiimageview in customCell
ios, objective-c, uiimageview
Solution
You have to change the loop as :
for ( UIView *currentView in cell.contentView.subviews)
{
if([currentView isKindOfClass:[UIImageView class]])
{
// here Do All the stuff for imageViews
}
}
Do All this stuff in `cellForRowAtIndexPath` and to change the imageView image take weak instance of imageView like this :
__weak UIImageView *weakImage = currentImageView;
[self.imageCache queryDiskCacheForKey:self.currentProduct.mirsaProductUrlImage[indexOfImages]
done:^(UIImage *image, SDImageCacheType cacheType) {
if (image) {
weakImage.image = image;
}
}];
Problem
hello i have product table and product details view for each product i have many images that are downloaded and cached on disk and memory on each time user select a product to check its details i am trying to retrieving cached images and set it up for my Four UIImageView inside the a custom Cell in UITableViewController i am not able to set the images although i can log them through NSLog() function i am using this code: ``` int index = 0; int indexOfImages = 1; self.imageCache = [[SDImageCache alloc] initWithNamespace:@"menuImage"]; for ( UIImageView *currentImageView in cell.contentView.subviews) { NSLog(@"the imageindex is: %d",indexOfImages); NSLog(@"the index is: %d",index); NSLog(@"the count is: %lu",(unsigned long)[self.currentProduct.mirsaProductUrlImage count]); if (index < [self.currentProduct.mirsaProductUrlImage count] ) { [self.imageCache queryDiskCacheForKey:self.currentProduct.mirsaProductUrlImage[indexOfImages] done:^(UIImage *image, SDImageCacheType cacheType) { if (image) { currentImageView.image = image; } }]; indexOfImages++; index++; } else { break; } } ``` and if i try to change the loop way to this ``` for ( UIImageView *currentImageView in self.tableView.subViews) ``` i got this error UITableViewWrapperView setImage:]: unrecognized selector sent to instance i just want to know if i am looping in a wrong way what i mean that i am not able to reach them through this loop or what is going on ?
