+/**
+ The YYLabel class implements a read-only text view.
+
+ @discussion The API and behavior is similar to UILabel, but provides more features:
+
+ * It supports asynchronous layout and rendering (to avoid blocking UI thread).
+ * It extends the CoreText attributes to support more text effects.
+ * It allows to add UIImage, UIView and CALayer as text attachments.
+ * It allows to add 'highlight' link to some range of text to allow user interact with.
+ * It allows to add container path and exclusion paths to control text container's shape.
+ * It supports vertical form layout to display CJK text.
+
+ See NSAttributedString+YYText.h for more convenience methods to set the attributes.
+ See YYTextAttribute.h and YYTextLayout.h for more information.

+ label.ignoreCommonProperties = YES;
+

+ text.yy_color = [UIColor grayColor];
+ [text yy_setColor:[UIColor redColor] range:NSMakeRange(0, 4)];
+
+ // Create text container
+ YYTextContainer *container = [YYTextContainer new];
+ container.size = CGSizeMake(100, CGFLOAT_MAX);
+ container.maximumNumberOfRows = 0;
+
+ // Generate a text layout.
+ YYTextLayout *layout = [YYTextLayout layoutWithContainer:container text:text];
+
+ dispatch_async(dispatch_get_main_queue(), ^{
+ label.size = layout.textBoundingSize;
