I have a URL with tag:

http://ws.cdyne.com/WeatherWS/Images/sunny.gif

When I do like this: 

NSURL *url=[NSURL URLWithString:@"http://ws.cdyne.com/WeatherWS/Images/sunny.gif"];

it's getting image in gdb and I am able to download from this URL. But when I write code like this: 

NSURL *url=[jsonItem objectForKey:@"PictureURL"];

(where jsonItem is dictionary and passing it to data and then to UIImage), then it shows an exception.

When I get the value of:

  [jsonItem objectForKey:@"PictureURL"];

in gdb then it shows like: 

2011-03-15 11:08:16.405 XML[1576:20b] jsonURKL  ..... ...

http://ws.cdyne.com/WeatherWS/Images/thunderstorms.gif   (in next line in gdb)

I need to download through this: 

NSURL *url=[jsonItem objectForKey:@"PictureURL"];

I am not able to do that. What could be wrong?

  • Can you post the code that creates the `jsonItem` dictionary? If not, can you `NSLog` the value of `[jsonItem objectForKey:@"PictureURL"]`? We need some more clues as to what class it is, etc. – Tim Mar 15 '11 at 06:02

Url itself one string. so you have to use below code

NSURL *url=[NSURL URLWithString:[jsonItem objectForKey:@"PictureURL"]];
NSData *data = [NSData dataWithContentsOfURL: url];

now setimgge with [UIImage imageWithData: data]; this code

please do this in following way,

NSURL *url=[NSURL URLWithString:[jsonItem objectForKey:@"PictureURL"]];
NSData *data = [NSData dataWithContentsOfURL: url];
cell.iconImage.image=[UIImage imageWithData: data];

    [jsonItem objectForKey:@"PictureURL"] contain only url, so i cannot use NSURL *url=[NSURL URLWithString:[jsonItem objectForKey:@"PictureURL"]]; instead i am using NSURL *url=[jsonItem objectForKey:@"PictureURL"]; – Ketan Shinde Mar 15 '11 at 06:13
  • its not the problem!! i guess!! but the problem is when i get the value of [jsonItem objectForKey:@"PictureURL"]; then it shows the url in next line.. is it matter or any kind of issue ?? – Ketan Shinde Mar 15 '11 at 06:14
  • i think..this is the right way...otherwise its a problem of yar parsing or on yar server side...if u trace it... let me know.. – makboney Mar 15 '11 at 06:36
  • does any body know how to get url without spaces or any other character in nsurl? – Ketan Shinde Mar 15 '11 at 06:43
