Trying to display an image I have stored using my web host.
Normally to dispaly an image this works per Apple example:
view2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sample.tiff"]];
But instead of the image file <sample.tiff> I want to display the same image which is stored at
I have looked at the code for retrieving a URL in UICatalog, and can display the web page, but I cannot figure out how to display the image.

if view2 is a UIImageView
view2.image = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:@"http://www.domain.com/image.jpg"]]];
I go over a lot of that is my JSON sections of my blog at
hope it helps

thanks for the reply.
This works:
view2 = [[UIImageView alloc] initWithImage:[UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:@"http://www.schoenburg.com/my.TIF"]]]];

Great find hijinks!
That looks like a great tutorial. After the Todo List series, I will probably have some web service tutorials on icodeblog. they will probably use XML-RPC.
Thanks for contributing that resource!

Okay, I got it to work, but, and this should be simple, but then what is with iPhone programming?
After defining two strings, NSString *one; and NSString *two; and using @property etc… and @synthsize …
I cannot find a way to concantenate the strings. So if one=”Hello”; and two =”world”; I want the result to be
“Hello world” stored in one. I would think it might be: one=one + two; but that generates and error.

The best way to do that is with a NSMutableString
NSMutableString *hello = [[NSMutableString alloc] initWithString:@"Hello"];
[hello appendString:@" World"];

Hijinks,
Thanks again. Why does Apple make it so difficult to find things like appendString? Maybe I am missing something
but I just cannot seem to find a reference to key words like this.

it is right in the NSMutableString reference
Their docs aren't really meant for new programers from what I can see. I come from a C background so its a lot easier for me to grasp. I have also done years of PHP work and if you come from that type of background the docs can be difficult since PHP isn't really Object Oriented in design

Your example worked for me. This is Apple's
- (void)appendString:( *)aString
The problem is that this is method which as I understand it cannot be placed inside another method. Apple also does
not give examples. I have programmed in Visual Basic, Visual FoxPro and PHP. The first two are objective in that you
might have a statement like this:
myText.Bold =TRUE; or myText.font =”Times Roman”;
Thanks again.
