How to programmatically set the background on a UICustomButton? - iphone

Question

I know this question has been asked and answered in other forums, but I can't seem to duplicate what they did and get it to work. I am trying to set the background to a button using a picture that I download from a server. Everything works until I try to make a NSData object with the contents of a URL. When I try and print the Data to the screen it comes back Null. What am I doing wrong?
myImageURLString = [[NSMutableString alloc] initWithString:#"http://destinationnexus.com"];
keyName = [businessButtonTagArray objectAtIndex:i];
arrayFromBusinessDictionary = [businessDictionary objectForKey:keyName];
stringToAddToMyImageURLString = [arrayFromBusinessDictionary objectAtIndex:1];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[button setTag:i];
button.frame = CGRectMake(xOffSet+(countForX*xMult), yOffset +(countForY*yMult), 215, 155);
[myImageURLString appendString:stringToAddToMyImageURLString];
NSLog(#"Appended URL String: = %#", myImageURLString);
NSURL *myImageURL = [NSURL URLWithString:#"http://destinationnexus.com/pictures/directory/ColdWater-Inn-in-Tuscumbia-Alabama-35674-8729//.jpg"];
NSLog(#"NSURL = %#", myImageURL);
//THIS IS WHERE I SEEM TO HAVE A PROBLEM.....
NSData *imageData = [[NSData alloc] initWithContentsOfURL:myImageURL];
UIImage *image = [[UIImage alloc] initWithData:imageData] ;
NSLog(#"Image Data = %#", imageData);
//UIImage *myImage = [UIImage imageWithData:imageData] ;
[button setBackgroundImage:image forState:UIControlStateNormal];
When I run the program this is what it outputs in the Log:
Appended URL String: = http://destinationnexus.com/pictures/directory/Auburn-University-Hotel-and-Center-in-Auburn-Alabama-36830-5429.jpg
NSURL = http://destinationnexus.com/pictures/directory/ColdWater-Inn-in-Tuscumbia-Alabama-35674-8729.jpg
Image Data = (null)

Answer 1

You should correct your myImageURL, by deleting 2 slashes at the end of URL.
The code goes something like this.
NSURL *myImageURL = [NSURL URLWithString:#"http://destinationnexus.com/pictures/directory/ColdWater-Inn-in-Tuscumbia-Alabama-35674-8729.jpg"];
NSData *imageData = [[NSData alloc] initWithContentsOfURL:myImageURL];
UIImage *image = [[UIImage alloc] initWithData:imageData] ;
[button setBackgroundImage:image forState:UIControlStateNormal];
[image release];
[imageData release];
