Displaying an Image from URL Objective C - iphone

Question

Is there any way of achieving the following that avoids using "initWithData" ? (Just in case you are curious, initWithData is getting my app flagged by Apple as using an illegal API sigh).
NSData * imageData = [NSData dataWithContentsOfURL : [NSURL URLWithString : [details image]]];
picture = [[UIImage alloc] initWithData:imageData];
Many thanks,
Martin

Answer 1

if you want to get the image data,then initialize a UIImage using that data:
NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: #"http://Serverurl/pic007.jpg"]];
cell.image = [UIImage imageWithData: imageData];
[imageData release];

First of all, you should do this asynchronously so that your thread won't block. Here is the code for the class:
#implementation AsyncImageView
+ (void)initialize {
[NSURLCache setSharedURLCache:[[SDURLCache alloc] initWithMemoryCapacity:0
diskCapacity:10*1024*1024
diskPath:[SDURLCache defaultCachePath]]];
}
- (void)setImageFromURL:(NSURL *)url{
/* Put activity indicator */
if(!activityIndicator) {
activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
CGRect frame = [activityIndicator frame];
frame.origin.x = (self.frame.size.width - frame.size.width)/2;
frame.origin.y = (self.frame.size.height - frame.size.height)/2;
activityIndicator.tag = 9999;
activityIndicator.frame = frame;
[self addSubview:activityIndicator];
[activityIndicator startAnimating];
}
/* Cancel previous request */
if(fetchImageConnection) {
[fetchImageConnection cancel];
}
[imageData release];
/* Start new request */
NSURLRequest *req = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad
timeoutInterval:30];
imageData = [NSMutableData new];
fetchImageConnection = [NSURLConnection connectionWithRequest:req
delegate:self];
[fetchImageConnection retain];
}
- (void)setImageFromDisk:(UIImage *)img {
self.image = img;
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[imageData appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
if(connection == fetchImageConnection) {
self.image = [UIImage imageWithData:imageData];
[[NSNotificationCenter defaultCenter] postNotificationName:#"imageDownloaded" object:self];
[activityIndicator removeFromSuperview];
[imageData release];
[activityIndicator release];
activityIndicator = nil;
imageData = nil;
fetchImageConnection = nil;
}
[connection release];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
[connection release];
NSLog(#"error: %#", error);
}
#end

Try this code:
NSString *imgString = #"https://www.lockated.com/system/attachfiles/documents/000/002/489/original/ZPMHaJUSjAGnUrVuOmbqoExRMryvcySVOIkJQMivnAntvpmpYd.jpg?1501833649";
NSData *imageData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:imgString]];
accountImageView.image = [UIImage imageWithData: imageData]; // accountImageView is imageView

Answer 4

NSData *receivedData = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://Serverurl/pic007.jpg"]];
self.image=nil;
UIImage *img = [[UIImage alloc] initWithData:receivedData ];
self.image = img;
[img release];
I hope this code will help you!!
