How to achieve background Image in UILabel as in pic? - iphone

Question

How to achieve below effect??
I want that when my UIImage width is smaller then UILabel width then my image should be displayed only once as below.
I already have done some more work with UILabel and UIImage. Refer to my previous question : How to stretch Image to fill the Label Width set in Background in UILabel?.
But now i want some more fun with UILabel... :D
EDIT :
SBLabel *lbl = [[SBLabel alloc] initWithFrame:CGRectMake(0, 50, 320, 28)];
lbl.text = #"Hello World!!!...";
UIImage *img = [UIImage imageNamed:#"cn3.png"];
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 50, 320, 28)];
imgView.image = img;
[lbl setNonRepeatingBackgroundImage:imgView];
[self.view addSubview:lbl];
[imgView release];

Answer 1

if (image.size.width < label.size.width ||image.size.height < label.size.height )
{
//rect here is frame of image
[img drawInRect:rect];
label.backgroudColor = [UIColor clearColor];
}

Answer 2

It seems like the most straightforward solution would be to have your UIImage sit behind your UILabel and your UILabel has a transparent background color.
Edit
Assuming you're using ARC...
SBLabel.h
#import <UIKit/UIKit.h>
#interface SBLabel : UILabel
#property (nonatomic, strong) UIImageView *nonRepeatingBackgroundImage;
#end
SBLabel.m
#import "SBLabel.h"
#implementation SBLabel
#synthesize nonRepeatingBackgroundImage;
- (void)setNonRepeatingBackgroundImage:(UIImageView *)aNonRepeatingBackgroundImage {
nonRepeatingBackgroundImage = aNonRepeatingBackgroundImage;
[self addSubview:aNonRepeatingBackgroundImage];
[self sendSubviewToBack:aNonRepeatingBackgroundImage];
[self setBackgroundColor:[UIColor clearColor]];
}
#end
You would need to call this setter method after you add the UILabel to the parent view. I have not tested but I believe it should work, might require some tweaks but hopefully it explains how to Subclass UILabel to make a custom enhancement such as this.

A subclass of UILabel could look like this (without ARC)
CustomLabel.h
#import <UIKit/UIKit.h>
#interface CustomLabel : UILabel {
UIImage *mImage;
}
#property (retain) UIImage *image;
#end
CustomLabel.m
#import "CustomLabel.h"
#implementation CustomLabel
- (void)dealloc {
self.image = nil;
[super dealloc];
}
- (void)drawRect:(CGRect)rect {
[mImage drawAtPoint:CGPointMake(0, 0)];
[super drawRect:rect];
}
- (UIImage*)image {
return mImage;
}
- (void)setImage:(UIImage *)image {
self.backgroundColor = [UIColor clearColor];
if(mImage)
[mImage release];
mImage = [image retain];
[self setNeedsDisplay];
}
#end
Usage
yourCustomLabel.image = [UIImage imageNamed:#"test.png"];
