Thanks in advance.

Answer 1

You can get the image from the above URL in the form of NSData :
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL urlWithString:#"http://abc.xyz.com/api/showImage.php"]];
UIImageView *imageView = [UIImageView alloc] initWithImage:[UIImage imageWithData:imageData]];

Answer 2

Its better to use Asyn download method when displaying images from the web.
You could create your own category on UIImageView or use the popular ones out there
SDWebImage.
[imageView setImageWithURL:[NSURL URLWithString:#"http://www.domain.com/path/to/image.jpg"]
placeholderImage:[UIImage imageNamed:#"placeholder.png"]];

Answer 3

Store response into array and then into an object say profile Object.I am using SDWebImage.
if U are geting image url at detailsObj.profileImage.Then use like below to set to imageview..
NSLog(#"response is:%#",userDetailsArray);
ProfileObject *detailsObj=[userDetailsArray objectAtIndex:0];
//in place of detailsObj.profileImage use url server link which is getting image.
if([detailsObj.profileImage isEqualToString:#""] || [detailsObj.profileImage isKindOfClass:[NSNull class]] || detailsObj.profileImage.length==0)
{
self.profileImageView.image=[UIImage imageNamed:#"NoImage.png"];
}
else
{
//without using SDWebImage
[self.profileImageView setImageWithURL:[NSURL URLWithString:detailsObj.profileImage]];
//if it is NSData getting from server
self.profileImageView.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL urlWithString:detailsObj.profileImage]]];
//or using SDWebImage
[self.profileImageView setImageWithURL:[NSURL URLWithString:detailsObj.profileImage] placeholderImage:[UIImage imageNamed:#"NoImage.png"]];
}
