How do you add multi-line text to a UIButton

Question

I have the following code     UILabel  buttonLabel     UILabel alloc  initWithFrame targetButton bounds   buttonLabel text     Long text string    targetButton addSubview buttonLabel    targetButton bringSubviewToFront buttonLabel        the idea being that I can have multi-line text for the button  but the text is always obscured by the backgroundImage of the UIButton  A logging call to show the subviews of the button shows that the UILabel has been added  but the text itself cannot be seen  Is this a bug in UIButton or am I doing something wrong

Setting lineBreakMode to NSLineBreakByWordWrapping  either in IB or code  makes button label multiline  but doesn t affect button s frame   If button has dynamic title  there is one trick  put hidden UILabel with same font and tie it s height to button s height with layout  when set text to button and label and autolayout will make all the work   Note  Intrinsic size height of one-line button is bigger than label s  so to prevent label s height shrink it s vertical Content Hugging Priority must be greater than button s vertical Content Compression Resistance

As to Brent s idea of putting the title UILabel as sibling view  it doesn t seem to me like a very good idea  I keep thinking in interaction problems with the UILabel due to its touch events not getting through the UIButton s view    On the other hand  with a UILabel as subview of the UIButton  I m pretty confortable knowing that the touch events will always be propagated to the UILabel s superview   I did take this approach and didn t notice any of the problems reported with backgroundImage  I added this code in the -titleRectForContentRect  of a UIButton subclass but the code can also be placed in drawing routine of the UIButton superview  which in that case you shall replace all references to self with the UIButton s variable    define TITLE LABEL TAG 1234  -  CGRect titleRectForContentRect  CGRect rect             define the desired title inset margins based on the whole rect and its padding     UIEdgeInsets padding    self titleEdgeInsets       CGRect titleRect   CGRectMake rect origin x      padding left                                     rect origin x      padding top                                     rect size width  -  padding right   padding left                                      rect size height -  padding bottom   padding  top            save the current title view appearance     NSString  title    self currentTitle       UIColor   titleColor    self currentTitleColor       UIColor   titleShadowColor    self currentTitleShadowColor           we only want to add our custom label once  only 1st pass shall return nil     UILabel   titleLabel    UILabel   self viewWithTag TITLE LABEL TAG         if   titleLabel                    no custom label found  1st pass   we will be creating  amp  adding it as subview         titleLabel     UILabel alloc  initWithFrame titleRect            titleLabel setTag TITLE LABEL TAG               make it multi-line          titleLabel setNumberOfLines 0            titleLabel setLineBreakMode UILineBreakModeWordWrap               title appearance setup  be at will to modify          titleLabel setBackgroundColor  UIColor clearColor             titleLabel setFont  self font             titleLabel setShadowOffset CGSizeMake 0  1             titleLabel setTextAlignment UITextAlignmentCenter             self addSubview titleLabel            titleLabel release                 finally  put our label in original title view s state      titleLabel setText title        titleLabel setTextColor titleColor        titleLabel setShadowColor titleShadowColor           and return empty rect so that the original title view is hidden     return CGRectZero      I did take the time and wrote a bit more about this here  There  I also point a shorter solution  though it doesn t quite fit all the scenarios and involves some private views hacking  Also there  you can download an UIButton subclass ready to be used

These days  if you really need this sort of thing to be accessible in interface builder on a case-by-case basis  you can do it with a simple extension like this   extension UIButton        IBInspectable var numberOfLines  Int           get   return titleLabel  numberOfLines    1           set   titleLabel  numberOfLines   newValue             Then you can simply set numberOfLines as an attribute on any UIButton or UIButton subclass as if it were a label  The same goes for a whole host of other usually-inaccessible values  such as the corner radius of a view s layer  or the attributes of the shadow that it casts

First of all  you should be aware that UIButton already has a UILabel inside it  You can set it using    setTitle forState    The problem with your example is that you need to set UILabel s numberOfLines property to something other than its default value of 1  You should also review the lineBreakMode property

Although it s okay to add a subview to a control  there s no guarantee it ll actually work  because the control might not expect it to be there and might thus behave poorly   If you can get away with it  just add the label as a sibling view of the button and set its frame so that it overlaps the button  as long as it s set to appear on top of the button  nothing the button can do will obscure it   In other words    button superview addSubview myLabel   myLabel center   button center
