# ZHAutoLinesLabel
ZHAutoLinesLabel is a subclass of UILabel, support contentInset and automatic multiple lines
# Why I create this label
### For automatic preferredMaxLayoutWidth
I love Autolayout, for label, I offen do this:
```
self.setContentCompressionResistancePriority(1000, forAxis: .Horizontal)
self.setContentCompressionResistancePriority(1000, forAxis: .Vertical)
self.setContentHuggingPriority(1000, forAxis: .Horizontal)
self.setContentHuggingPriority(1000, forAxis: .Vertical)
```
If we set `numberOfLines = 0`, label will automatically resize it approtiately.
I love Interface Builder, I offen set these four priorities in IB like this
However, there's a property `preferredMaxLayoutWidth`, in IB, it's
This can be automatic only for iOS8, which means the value will be equal to view's width.
If our project supports for iOS7 or iOS6, we will have a warning:
```
Main.storyboard: warning: Attribute Unavailable: Automatic Preferred Max Layout Width is not available on iOS versions prior to 8.0
```
we have to give it an explicit value in IB to get rid of it. If we want it's automatic, we have to link this label, then update `preferredMaxLayoutWidth` in code. This is trivial.
To let iOS7 have same behavior like iOS8 and get rid of this kind of warning, I created this label.
What you need to do is always set `preferredMaxLayoutWidth` explicitly and it will work automatically.
(Better to choose same width value as label, this will give you correct layout in IB)
### For contentInset just like UITextView
Sometimes, we want label to have a background and margin around it. One way is to creat a container view and add a lable on that, this is bad in IB or code.
ZHAutoLinesLabel has a new property `contentInset: UIEdgeInsets`, same with UITextView, also, it works with Autolayout.
