UILabel TextAlignement Vertical Top - cocoa-touch

Question

I have a great problem, I have a UILabel created programmatically and then connect via Interface builder, where i have positionated where I need, but i see that the text i set in it it's printed in the center of the UILabelBox, I have found a lot of question but i haven't know I can use it, I have found this:
//
// VerticallyAlignedLabel.h
//
#import <Foundation/Foundation.h>
typedef enum VerticalAlignment {
VerticalAlignmentTop,
VerticalAlignmentMiddle,
VerticalAlignmentBottom,
} VerticalAlignment;
#interface VerticallyAlignedLabel : UILabel {
#private
VerticalAlignment verticalAlignment_;
}
#property (nonatomic, assign) VerticalAlignment verticalAlignment;
#end
//
// VerticallyAlignedLabel.m
//
#import "VerticallyAlignedLabel.h"
#implementation VerticallyAlignedLabel
#synthesize verticalAlignment = verticalAlignment_;
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
self.verticalAlignment = VerticalAlignmentMiddle;
}
return self;
}
- (void)setVerticalAlignment:(VerticalAlignment)verticalAlignment {
verticalAlignment_ = verticalAlignment;
[self setNeedsDisplay];
}
- (CGRect)textRectForBounds:(CGRect)bounds limitedToNumberOfLines:(NSInteger)numberOfLines {
CGRect textRect = [super textRectForBounds:bounds limitedToNumberOfLines:numberOfLines];
switch (self.verticalAlignment) {
case VerticalAlignmentTop:
textRect.origin.y = bounds.origin.y;
break;
case VerticalAlignmentBottom:
textRect.origin.y = bounds.origin.y + bounds.size.height - textRect.size.height;
break;
case VerticalAlignmentMiddle:
// Fall through.
default:
textRect.origin.y = bounds.origin.y + (bounds.size.height - textRect.size.height) / 2.0;
}
return textRect;
}
-(void)drawTextInRect:(CGRect)requestedRect {
CGRect actualRect = [self textRectForBounds:requestedRect limitedToNumberOfLines:self.numberOfLines];
[super drawTextInRect:actualRect];
}
#end
Anyone can help me how I can use it please?

I know it may be late to answer, but I did it this way:
I made a Category for UILabel and call -setVerticalAlignmentTop when it was needed.
// UILabel(VAlign).h
#import <Foundation/Foundation.h>
#interface UILabel (VAlign)
- (void) setVerticalAlignmentTop;
#end
// UILabel(VAlign).m
#import "UILabel(VAlign).h"
#implementation UILabel (VAlign)
- (void) setVerticalAlignmentTop
{
CGSize textSize = [self.text sizeWithFont:self.font
constrainedToSize:self.frame.size
lineBreakMode:self.lineBreakMode];
CGRect textRect = CGRectMake(self.frame.origin.x,
self.frame.origin.y,
self.frame.size.width,
textSize.height);
[self setFrame:textRect];
[self setNeedsDisplay];
}
#end

You can do it as follows.......
Set your label's numberOfLines property 0 from IB
Set your label's lineBreakMode as UILineBreakModeWordWrap (very very important)
now whatever you set on the label just append few #"\n" to it.....
ex.-
[yourTextLabel setText:#"myLabel\n\n\n\n\n"];
