I'm developing an iphone app with XMPP.
I'm trying to print the images of the logged in users in the chat room. This is the code I have.
XMPPvCardAvatarModule *avatar = [[XMPPvCardAvatarModule alloc]initWithvCardTempModule:[[self appDelegate]xmppvCardTempModule]];
XMPPJID *jidUser = [XMPPJID jidWithString:key];
NSData *foto = [[NSData alloc]initWithData:[avatar photoDataForJID:jidUser]];UIImage *pic = [UIImage imageWithData:fotoData];
UIImageView *picVista = [[UIImageView alloc] initWithImage:pic];
[self.commentsGente addSubview:picVista];
But that NSData is always 0KB, so there's obviously no image. How to do this?
NSData *photoData = [[[self appDelegate] xmppvCardAvatarModule]photoDataForJID:user.jid];
UIImageView *picVista;
picVista.image = [UIImage imageWithData:photoData];
try this it works fine for me

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 have a window in which I want to display an image in a specific block of that window. The image is retrieved from the local XML file. I parsed the XML file and got the image value in the log, but I don't know how to put it in that specific block. The below image pasted for the reference.
The arrow mark represents that within this UIImageView I need to get the image. Also, I doubt that I need to mention any name for reference to UIIMageView in storyboard. Suggest me an idea.

My parser code:
NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"Sample.xml"];
NSData *data = [[NSData alloc] initWithContentsOfFile:path];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:data];
[xmlParser setDelegate:theParser]
After this I am using this code for getting image:
UIImage *image = [UIImage imageWithContentsOfFile:#"/Users/administrator/Desktop/imageApp/resources/Main_pic1.png"];
After this I don't know how to continue.
Yes, you have to create IBOutlet in .h file
like IBOutlet UIImageView *imgview; and connect imgview with your UIImageview from xib.
After that you can set image to image view.
NSURL *URL = [NSURL URLWithString:[your url which u get form local xml]];
NSData *imageData = [NSData dataWithContentsOfURL:URL];
UIImage *image = [UIImage imageWithData:imageData];
imgview.image=image;
Ttry this, It may help you.
You can directly pass the url image to Uiimageview by :
YourImageView.image = [UIImage imageWithContentsOfURL:YourUrl];
It's possible to do the equivalent by going through NSData, but it's a bad idea. Instead, the image should be downloaded asynchronously using NSURLConnection, and only once it's fully downloaded should it be converted into a UIImage and assigned to the image view.
Save all your urls in an say NSMutableArry *UrlArray then
int x = 0;
int y = 10;
for (int i = 0; i< [UrlArray]; i++)
{
UIImageView *imageView = [[[UIImageView alloc]initWithFrame:CGRectMake(3+x,y, 80,
80)]autorelease];
imageView.backgroundColor = [UIColor blueColor];
if (x >= 300)
{
x = 0;
y = y+imageView.frame.size.height+3;
imageView.frame = CGRectMake(x+3 , y, 80, 80);
}
CIImage *beginImage = [CIImage imageWithContentsOfURL:[UrlArray ObjectAtIndex:i]];
imageView.image = [UIImage imageWithCIImage:beginImage];
x = x+imageView.frame.size.width+5;
[self.view addSubview:imageView];
}
will do the work i guess;
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]]];
Here Iam having a problem.Actually I implemented the facebook integration in my application and I need to post the images with text but I dont have any idea how to work on this.can anyone suggest this with a sample code so that it is very helpful for me.
Anyone's help will be much appreciated.
I assume that you want to draw some text in an image, and then upload the image to Facebook.
At first, we need to draw the original image and the desired text into a new image.
UIGraphicsBeginImageContext(CGSizeMake(320.0, 320.0));
CGContextRef context = UIGraphicsGetCurrentContext();
// Draw the original image
[image drawInRect:CGRectMake(0, 0, 320.0, 320.0)];
// Draw the text
[#"text" drawInRect:CGRectMake(...) withFont:[UIFont systemFontOfSize:20.0];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
And then, convert the image into NSData and call Facebook's "photos.upload" API to upload it.
NSMutableDictionary *args = [[[NSMutableDictionary alloc] init] autorelease];
[args setObject:#"caption" forKey:#"caption"];
FBRequest *uploadPhotoRequest = [FBRequest requestWithDelegate:self];
NSData *data = UIImagePNGRepresentation(newImage);
[uploadPhotoRequest call:#"photos.upload" params:args dataParam:data];
If you want to upload the images to your server, and post a small story to Facebook's wall. Use the stream API.
FBStreamDialog *dialog = [[[FBStreamDialog alloc] init] autorelease];
dialog.delegate = self;
dialog.userMessagePrompt = #"Prompt";
NSString *name = #"Your caption";
NSString *src = #"http://example.com/path/of/your/image";
NSString *href = #"http://what/happens/if/the/user/click/on/the/image";
NSString *attachment = [NSString stringWithFormat:#"{\"name\":\"%#\",\"media\":[{\"type\":\"image\", \"src\":\"%#\", \"href\":\"%#\"}]}", name, src, href];
dialog.attachment = attachment;
[dialog show];
Maybe you would be happy using BMSocialShare. It's a simple lib I wrote.
BMFacebookPost *post = [[BMFacebookPost alloc]
initWithTitle:#"Simple sharing via Facebook, Email and Twitter for iOS!"
descriptionText:#"Posting to Facebook, Twitter and Email made dead simple on iOS. Simply include BMSocialShare as a framework and you are ready to go."
