NSLog(@"Img URL === %@",tmpImgURLStr);

NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",tmpImgURLStr]]]; 

UIImage *myimage = [[UIImage alloc] initWithData:mydata];
[logoImg setImage:myimage];

Answer 1

As far as I can tell from your url - you have pdf, not an image. Usually WebViews are used for displaying this sort of data.

Update

Your NSData initiation is kinda too long. You can actually initiate a URL without supplying formatted string:

NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:tmpImgURLStr]];

Also I've noticed that your URL is without protocol. You may want to try adding http:// or https:// to it and then see what happens. And just in case check if your logoImg is actually wired to the NSImageView in your NIB.

Answer 2

Try this code instead of yours .. May be it will work..

logoImg=[[IUImageView alloc]initWithFrame:CGRectMake(10,10,300,460)];
NSLog(@"Img URL === %@",tmpImgURLStr);
NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:tmpImgURLStr]]];
UIImage *myimage = [[UIImage alloc] initWithData:mydata];
[logoImg setImage:myimage];

-Happy coding....
