<p>This guide provides details for how to migration between major versions of <code>IGListKit</code>.</p>
|
|
<a href='#from-1-x-to-2-x' class='anchor' aria-hidden=true><span class="header-anchor"></span></a><h2 id='from-1-x-to-2-x'>From 1.x to 2.x</h2>
|
|
|
|
<p>For details on all changes in IGListKit 2.0.0, please see the <a href="https://github.com/Instagram/IGListKit/blob/master/CHANGELOG.md#200">changelog</a>.</p>

<a href='#iglistdiffable-conformance' class='anchor' aria-hidden=true><span class="header-anchor"></span></a><h3 id='iglistdiffable-conformance'>IGListDiffable Conformance</h3>
|
|
|
|
<p>If you relied on the default <code>NSObject<IGListDiffable></code> category, you will need to add <code>IGListDiffable</code> conformance to each of your models. To get things working as they did in 1.0, simply add the following to each of your models:</p>
|
|
|
|
<p><strong>Objective-C</strong>
|
|
“`objc</p>
|
|
<a href='#import-iglistkit-iglistdiffable-h' class='anchor' aria-hidden=true><span class="header-anchor"></span></a><h1 id='import-iglistkit-iglistdiffable-h'>import <IGListKit/IGListDiffable.h></h1>
|
|
|
|
<p>// Header
|
|
@interface MyModel <IGListDiffable></p>
|
|
|
|
<p>// Implementation
|
|
- (id<NSObject>)diffIdentifier {
|
|
return self;
|
|
}</p>
|
|
|
|
<ul>
|
|
<li>(BOOL)isEqualToDiffableObject:(id<IGListDiffable>)object {
|
|
return [self isEqual:object];
|
|
}
|
|
”`</li>
|
|
</ul>
|
|
|
|
<p><strong>Swift</strong>
|
|
“`swift
|
|
import IGListKit</p>
|
|
|
|
<p>extension MyModel: IGListDiffable {
|
|
func diffIdentifier() -> NSObjectProtocol {
|
|
return self
|
|
}</p>
|
|
|
|
<p>func isEqual(toDiffableObject object: IGListDiffable?) -> Bool {
|
|
return isEqual(object)
|
|
}
|
|
}
|
|
”`</p>
|
|
|
|
<p>However we recommend writing more thorough identity and equality checks. Check out our guide to <a href="https://instagram.github.io/IGListKit/iglistdiffable-and-equality.html">IGListDiffable and Equality</a> for more info.</p>
