How to get image from server by sending one parameter with url.
GET HTTPRequest has to be use to send request.
回答1:
You can get image from server with specific path of that image with image name.
UIImage* serverImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString: @"http://example.com/image_name.png"]]];
then you can use serverImage anywhere you want.
回答2:
Try to use this :
-(UIImage*)getImageFromURLwithUrl:(NSString*)imgURLStr
{
NSMutableURLRequest *requestWithBodyParams = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:imgURLStr]];
NSData *imageData = [NSURLConnection sendSynchronousRequest:requestWithBodyParams returningResponse:nil error:nil];
UIImage *image = [UIImage imageWithData:imageData];
return image;
}

A pretty useful project that I use to load Images without blocking the UI is the SDWebImage. It adds an asynchronous category on UIImageView, enabling you to load an image with just one line of code:
[myImageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
