As seems to be fairly common when subclassing UITextView on iOS 7.1, I'm hitting an infinite loop in layoutSubviews when using this pod with the view having scrolling enabled. With scrolling disabled it doesn't work to resize but otherwise doesn't cause an infinite loop.

Hi, it would be great if you could add a screenshot to the podspec and push the update to the specs repo. The screenshot is currently displayed on http://feeds.cocoapods.org and in future it will displayed on the search of http://cocoapods.org.

To learn more about the screenshot attribute, you can check the documentation here: http://guides.cocoapods.org/syntax/podspec.html#screenshots

This pull requests corrects the spelling of CocoaPods 🤓 https://github.com/CocoaPods/shared_resources/tree/master/media

One day I’ll make a bot that looks through the READMEs of all Pods, looks to see if it uses “Cocoapods” and PRs “CocoaPods” :D

Created with cocoapods-readme.

How would the constraints from the examples be replicated programmatically?

My MBAutoGrowingTextView is inside of a scrollview and here is what I tried

//the horizontal positioning of the textView [_internalScrollView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[_textView(scrollViewSize)]|" options:NSLayoutFormatDirectionLeadingToTrailing metrics:metrics views:elementDict]];

//a constraint I added that is intended to make the textview expand downward, instead of upward (was able to make this work in the example project with Interface Builder, but doesn't work in my app programmatically [_internalScrollView addConstraint:[NSLayoutConstraint constraintWithItem:_textView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:_internalScrollView attribute:NSLayoutAttributeTop multiplier:1.0f constant:1.0]];

//the three sizing constraints [_internalScrollView addConstraint:[NSLayoutConstraint constraintWithItem:_textView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationGreaterThanOrEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:33]];

    [_internalScrollView addConstraint:[NSLayoutConstraint constraintWithItem:_textView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:33]];

    [_internalScrollView addConstraint:[NSLayoutConstraint constraintWithItem:_textView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationLessThanOrEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:200]];

Right now an assertion will fire if there's no NSLayoutRelationEqual relation on a height constraint, even if there's a NSLayoutRelationGreaterThanOrEqual relation in place. It seems unnecessary to have both, as the equal relation could be created on the fly. I was stuck for a little while until I realized that it was a requirement. At the very least it should be made clearer in the documentation, as explicit height constraints aren't always required for a fully constrained layout.
