FB_Graph_Response = [FB_Graph doGraphGet:#"me/friends" withGetVars:nil];
// NSLog(#"%#",[FB_Graph_Response.htmlResponse JSONValue]);
arrFriendsList = [[[FB_Graph_Response.htmlResponse JSONValue]objectForKey:#"data"]retain];
I have accessed the friends list in my app by using fb graph api(above request),
but i am not able to get friend's profile images. how to get it?
Get the id (or the nick) of the user, and get the picture from https://graph.facebook.com/idOrNick/picture
This works without any kind of auth.
Small sample:
NSString id = getTheIdOrNick;
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://graph.facebook.com/%#/picture", id]];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *image = [UIImage imageWithData:data];
//UIImageView *imgView = [[UIImageView alloc]init];
//imgView.image = image;

i am trying to fetch an image from URL, but i am not able to do it.
can any one let me know what went wrong
find the code below for your reference.
NSString *ImageURL = #"http://images.pcmac.org/SiSFiles/Schools/TN/JacksonMadisonCounty/RoseHillMiddle/Uploads/Locations/{B690E93E-F7C9-48AF-B72A-BFF944FA6D4A}_104_9169.JPG";
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]];
img.image = [UIImage imageWithData:imageData];
where img is a UIImageView
i just create DEMO of Your ImageURL you just Need to put Code Bellow:-
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *ImageURL = #"http://images.pcmac.org/SiSFiles/Schools/TN/JacksonMadisonCounty/RoseHillMiddle/Uploads/Locations/{B690E93E-F7C9-48AF-B72A-BFF944FA6D4A}_104_9169.JPG";
ImageURL =[ImageURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSLog(#"img url ==%#",ImageURL);
NSData *data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:ImageURL]];
UIImage *MYimage = [UIImage imageWithData:data];
NSLog(#"==%#",MYimage);
[imgview setImage:MYimage];
}
Download the Demo i just created of your image URL:-

Thank you :)
Try this.......
NSString *ImageURL = #"http://images.pcmac.org/SiSFiles/Schools/TN/JacksonMadisonCounty/RoseHillMiddle/Uploads/Locations/{B690E93E-F7C9-48AF-B72A-BFF944FA6D4A}_104_9169.JPG";
NSData *data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:ImageURL]];
UIImage *IMG = [UIImage imageWithData:data];
img.image = IMG;
This is because you have "{" and "}" in your imageURL so you are not able to get your image, so just replace this braces.
-(NSString*)replace:(NSString*)string
{
NSString *str = [[string stringByReplacingOccurrencesOfString:#"{" withString:#"%7B"] stringByReplacingOccurrencesOfString:#"}" withString:#"%7D"];
return str;
}
You have to create your url object in the following way :
NSURL *url = [NSURL URLWithString:[ImageURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
then use that url to fetch data. Hope it will work for you.
there are multiple ways to get Image from Url. you can use anyone. but the fastest one that i have tried is
-(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;
}
In my Iphone app.i'm not getting the images in imageview.Those images are coming from a link.
link is http://pointngo.testshell.net/Images/2013-01-05%2001-05-59_20110623033304.jpg
i'm using this code.
UIImage* myImage = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:str]]];
Try this :-
str = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
UIImage* myImage = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:str]]];
Hope it helps you
try this code...
NSURL *imgURL = [NSURL URLWithString:#"http://pointngo.testshell.net/Images/2013-01-05%2001-05-59_20110623033304.jpg"];
NSData *data = [[NSData alloc] initWithContentsOfURL:imgURL];
UIImage *tmpImage = [[UIImage alloc] initWithData:data];
yourImageView.image = tmpImage;
You should make sure the [NSData dataWithContentsOfURL: [NSURL URLWithString:str]] returns not nil . if nil you should use dataWithContentsOfURL:options:error:.
quote Apple Documentation :
Return Value
A data object containing the data from the location specified by aURL. Returns nil if the data object could not be created.
Discussion
If you need to know what was the reason for failure, use dataWithContentsOfURL:options:error:.
I've tried the following and it is working fine for me:
NSString *str = #"http://pointngo.testshell.net/Images/2013-01-05%2001-05-59_20110623033304.jpg";
//NSLog(#"Image data %#", [NSData dataWithContentsOfURL: [NSURL URLWithString:str]]);
UIImageView *imgv = [[[UIImageView alloc] initWithFrame: CGRectMake(50.0, 50.0, 100.0, 100.0)] autorelease];
imgv.image = [UIImage imageWithData:[NSData dataWithContentsOfURL: [NSURL URLWithString:str]]];
imgv.contentMode = UIViewContentModeScaleAspectFill;
[self.view addSubview:imgv];
i've managed to incorporate the twitter api into my app and i can call all the data and put it into my app, except for the image.
i've managed to find tuts on how to get the picture if you provide the url, but i want to get the addy from my dictionary to then be put into my uiimageview.
Any help would be appreciated, here is what i have sourced
NSData *imageData =
[[NSData alloc] initWithContentsOfUrl:
[NSString
stringWithContentsOfUrl:
[NSURL URLWithString:#"http://mydomain.com"]
encoding: NSUTF8StringEncoding
error: nil
]
];
UIImage* image = [[UIImage alloc] initWithData:imageData];
[marcaBackground setImage:image];
[imageData release];
[image release];
this is what i have already set up`-(NSString*)author {
return [[contents objectForKey:#"user"] objectForKey:#"screen_name"];
`
NSString *author=[(Tweet*)[auth objectAtIndex:indexPath.row] author];
could someone please advise me on what needs changing for it to work??
NSData *imageData = [[NSData alloc] initWithContentsOfUrl: [NSURL URLWithString:#"http://..."]];
The rest is correct.
Ii'm using this NSURL code to display an image. what I want to do is to insert a url from my database table in place of the static url shown in the code below:
Does anyone know how I should proceed?
NSURL *url = [NSURL URLWithString:#"http://www.nyapplecountry.com/images/photosvarieties/redrome04.jpg"];
UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]];
[self.view addSubview:[[UIImageView alloc] initWithImage:image]];
[self.containerView addSubview:self.mainView];
I was thinking of something like:
NSString *urlAddress = [NSString stringWithFormat:#"%#", place.url];
where place.url is coming from my db table. I'm missing something though, not sure what.
thanks for any help
Is place.url a NSString object and the full URL to the image? Then it would be as simple as
NSURL *url = [NSURL URLWithString:place.url];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
You can't do it that way. You have to read image from data base and initialize UIImage with that data.
I have a string variable tmpImgURLStr which contains URL like www.abc.com/img.png. i want to display that image in my imageView for that i have use some code but it's not working which is given below:
NSLog(#"Img URL === %#",tmpImgURLStr);
NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#",tmpImgURLStr]]];
UIImage *myimage = [[UIImage alloc] initWithData:mydata];
[logoImg setImage:myimage];
As far as I can tell from your url - you have pdf, not an image. Usually WebViews are used for displaying this sort of data.
Update
Your NSData initiation is kinda too long. You can actually initiate a URL without supplying formatted string:
NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:tmpImgURLStr]];
Also I've noticed that your URL is without protocol. You may want to try adding http:// or https:// to it and then see what happens. And just in case check if your logoImg is actually wired to the NSImageView in your NIB.
Try this
NSURL *imageurl = [NSURL URLWithString:#"http://www.chakrainteractive.com/mob/ImageUpoad/pic2-2.png"];
NSData *imagedata = [[NSData alloc]initWithContentsOfURL:imageurl];
UIImage *image = [UIImage imageWithData: imagedata];
[logoImg setImage: image];
Try this code instead of yours .. May be it will work..
logoImg=[[IUImageView alloc]initWithFrame:CGRectMake(10,10,300,460)];
NSLog(#"Img URL === %#",tmpImgURLStr);
NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:tmpImgURLStr]]];
UIImage *myimage = [[UIImage alloc] initWithData:mydata];
[logoImg setImage:myimage];
-Happy coding....
