I have a NSMutableArray where it stores url to a image. And this NSMutableArray is called userPic. From my server it only prints out the url: not JSON or anything, only the url.
I can see in the output in Xcode that it shows the url, but how to I get this url in userPic to a background? Im trying to addSubView with the image for a background.
If something is unclear, sorry about that. Just let me know.
Please try to use this one.And i think your URL at index 0 of your array.
NSURL *imgURL = [NSURL URLWithString:[userPic objectAtIndex:0]]; // put your particular index where your image url in your array...
NSData *imgData = [[NSData alloc]initWithContentsOfURL:imgURL];
UIImage *img = [UIImage imageWithData: imgData];
[newView setBackgroundColor:[UIColor colorWithPatternImage:img]]

I have imageView i want to load image from url but it is not loading i am using following code
pdfView.hidden=NO;
webView.hidden=NO;
pictureImageView.hidden=NO;
pdfView.backgroundColor=[UIColor clearColor];
doneButton = [[UIBarButtonItem alloc]initWithTitle:#" Done " style:UIBarButtonItemStyleBordered target:self action:#selector(doneButtonClick)];
self.navigationItem.leftBarButtonItem =doneButton;
webView.backgroundColor=[UIColor clearColor];
NSLog(#"File Name is %#",fileName);
NSLog(#"Enterning in the ImageSection");
NSString *ImageURL = fileName;
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]];
pictureImageView.image = [UIImage imageWithData:imageData];
Instead of this if i want to give from local like below then also it does not show image in imageView any idea how to load image from url thank
pictureImageView.image=[UIImage imageNamed:#"starblue.png"];
First set frame of that image and then write this line after add image in pictureImageView
[self.view bringSubviewToFront:pictureImageView];
Code looks fine
Things to check
Url contain a valid image
Set ImageView alloc it properly set frame and then add image
UIImageView *pictureImageView=[[UIImageView alloc]initWithFrame:CGRectMake(10, 20, 50, 50)];
Then do the rest
This is synchronous image loading that will block the main thread activities.Prefer to use asynchronous image download using AFNetworking or AsynchImageview
Use this code for show image in Url .
NSString *image=[NSString stringWithFormat:#"Your URL"] stringByReplacingOccurrencesOfString:#" " withString:#"%20"];
NSLog(#"%#",image);
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:image]];
Yourimageview=[UIImage imageWithData:imageData];
pictureImageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:imgurl]]];
The code below works fine if I give statically but
imgDescView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:
[NSURL URLWithString:[NSString stringWithFormat:#"http://4cing.com/mobile_app/uploads/pageicon/6.jpg"]]]];
Same code - I am passing the image url name dynamically it's not working
imgDescView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:
[NSURL URLWithString:[NSString stringWithFormat:#"%#",[imagename objectAtIndex:0]]]];
You need to verify the NSArray contents. Log out the objects of the array:
NSLog(#"imagename = %#",[imagename description]);
Also, a side-note - might want to think about loading that image dynamically. I wrote a class that makes this pretty painless:

The answer is geared toward using in TableViews (where lag would really hurt performance), but you can (and I do) use this for any web image loading. This keeps the UI fluid and is very fast.
NSMutableArray *imagename = [[NSMutableArray alloc] initWithObjects:#"http://4cing.com/mobile_app/uploads/pageicon/6.jpg", nil];
UIImageView *imgDescView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 200, 200)];
imgDescView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:
[NSURL URLWithString:[NSString stringWithFormat:#"%#",[imagename objectAtIndex:0]]]]];
it is working ... i think u r not creating array properly.
Hi create url in this manner
[NSURL URLWithString:[[NSString stringWithFormat:#"%#",[imagename objectAtIndex:0]] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]
i think it will work and will resolve ur problem.
I want get image from public perfil of Facebook and show it in my iPhone. I'm using the Facebook Developer method "getPhoto" but I can´t show any image?
Can someone help me?
NSString *url = [[NSString alloc] initWithFormat:#"https://graph.facebook.com/%#/picture",objectID];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url]]];
As told Previously your problem to retrieve the object id. Here is the solution:-
To retrieve the images of your friend. Create the connection with the url
NSString *url = [[NSString alloc] initWithFormat:#"https://graph.facebook.com/me/friends?access_token=%#",accessTokenValue];
above url when hit returns an array of dictionary in which name of your friend and his id is written. Just Json parse that you will get the id of the person.
you need to use graph api for this purpose
NSString *url = [[NSString alloc] initWithFormat:#"https://graph.facebook.com/%#/picture",objectID];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url]]];
Is there a way to get a current image to an object of UIImage? I have tried casting TTPhoto to UIImage, but it doesn't work.
I did this differently. My Photo source is generated using JSON data so I couldn't use the method above as the photo source is different every time. Instead I used the URLForVersion method on TTPhoto to download the image into a UIImage.
NSURL *imageURL = [NSURL URLWithString:[self.centerPhoto URLForVersion:TTPhotoVersionLarge]];
NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
UIImage *image = [UIImage imageWithData:imageData];
I figured it out. We can use TTPhotoViewController's instance variable centerImageIndex. This will give us the index of the current image.
I am fetching image from server and save it on a NSMutableArray. The result of array like that
myarray={"roger_50.jpg",....};
Now i dont know how to access this image on table view.
Just have proper URL for image in array. And pass it to NSURL object as a link.
NSURL *imageURL = [NSURL URLWithString:[myarray objectAtIndex : yourindex]];
NSData *data = [NSData dataWithContentsOfURL:imageURL];
UIImage *image = [[UIImage alloc] initWithData:data];
Have a nice coding.
Stay Hungry, Stay Foolish...
i hope the thing you are getting from array are only the names you can retrieve images from server in only two ways i) in nsdata ii)by url of the images on sever .By this way you cann't access the images.
