12 years ago I have do some modify to support dynamic loading remote images, but it add a depend on SDWebImage(maybe rewrite the loading progress), add it to the processText method else if (currentSupernode.isImage) { //replace active string with emptySpace NSRange elementContentRange = NSMakeRange(currentSupernode.startLocation, tagRange.location - currentSupernode.startLocation); NSString * elementContent = [processedString substringWithRange:elementContentRange];
UIImage *img = nil;
if ([elementContent hasPrefix:@"http"]) {
// image from http
// try to load from cache
img = [[SDImageCache sharedImageCache] imageFromKey:elementContent];
if (!img) {
// not in cache, load it from URL
img = [UIImage imageNamed:@"loading"];
NSURL *imgURL = [NSURL URLWithString:elementContent];
NSLog(@"loading image %@", elementContent);
// download it
id successblock = ^(UIImage *image) {
NSLog(@"loaded %@", elementContent);
currentSupernode.image = image;
currentSupernode.style.leading = image.size.height;
[self didMakeChanges];
if ([self superview]) [self setNeedsDisplay];
};
id failedblock = ^(NSError *error) {
NSLog(@"load image failed %@", elementContent);
};
[[SDWebImageManager sharedManager] downloadWithURL:imgURL
delegate:self
options:0
success:successblock
failure:failedblock];
}
}
else
{
img = [UIImage imageNamed:elementContent];
}
if (img) {
currentSupernode.image = img;
}
else {
NSLog(@"FTCoreTextView :%@ - Couldn't find image '%@' in main bundle", self, NSStringFromRange(elementContentRange));
[processedString replaceCharactersInRange:tagRange withString:@""];
}

Hi, It would be awesome if we can load images remotely :) ! I tried to but it did not work. Maybe you can edit my code to implement it easier in the repo ? look at this : stackoverflow.com/questions/11927942/ios-core-text-loosing-context-when-drawing-image-inside-a-block
