Generating Thumbor URLs on iOS
Faster image loading, better caching, easy.
Written by Jim Puls.
A little while back, we talked about dynamic images with Thumbor.
*Thumbor is an open-source, on-demand image service which allows for server-side cropping, resizing, and compositing of images. This is particularly useful for applications where the density and resolution of the target screen can vary wildly. Rather than downloading a large image and scaling it to fit the display, the image is requested at the exact desired size and the server does the work on-demand to resize it before delivering.*
It’s really slick and very easy to use. In five lines of code, you can request a resized version of an image:
NSURL *****baseURL **=** [NSURL URLWithString:@"http://my.thumbor.server"]; NSURL *****imageURL **=** [NSURL URLWithString:@"http://www.google.com/images/srpr/logo3w.png"]; TUOptions *****opts **=** [[TUOptions alloc] init]; opts.targetSize **=** CGSizeMake(100, 100); NSURL *****u **=** [NSURL TU_secureURLWithOptions:opts imageURL:imageURL baseURL:baseURL securityKey:@"use-a-better-security-key-than-this"];
