How to show Image with space in its name in objective c - iphone

I want to show image in imageview from Url and it is having space in its nameā€¦
// NSString* imageURL = #"http://dev.squealrs.com/imaging.php/image-name.jpg?height=45&noimg=100&image=/wp-content/uploads/sqbrands/GMT-July-cover1344489425.jpg";
NSString* imageURL = #"http://dev.squealrs.com/imaging.php/image-name.jpg?height=45&noimg=100&image=/wp-content/uploads/sqbrands/Sookie Stackhouse small1343970416.jpg";
NSData* imageData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:imageURL]];
UIImage* image = [[UIImage alloc] initWithData:imageData];
[ImageWithspace setImage:image];
but no image is shown bcoz uncommented imageURL contains space in imagename, if i use commented imageURL than it display image in imageview :( ....give me some solution

You need to encode the url:
NSString *encoded = [imageURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];

You need to encode the URL before you use it to create the NsURL. There is a built in class that will help you encode the string.
Here is an example of encoding a string for use with NSURL: NSURL Encoding in ObjC

NSURL *url = [[NSURL alloc] initWithString:[myurlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
This happens because the white spaces in the url are not treated hence percent encoding is used

NSString* imageURL = #"http://dev.squealrs.com/imaging.php/image-name.jpg?height=45&noimg=100&image=/wp-content/uploads/sqbrands/Sookie Stackhouse small1343970416.jpg";
NSString *spaceUrl = [[NSString stringWithFormat:imageURL] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
spaceUrl = [spaceUrl stringByReplacingOccurrencesOfString:#" " withString:#"%20"];
NSData* imageData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:spaceUrl]];
UIImage* image = [[UIImage alloc] initWithData:imageData]
[ImageWithspace setImage:image];
Just Copy paste this code and see. IF you have problem still then feel free to ask

Cannot Fetch UIImage from URL

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;
}

Why won't this image show up? Using NSData and initWithData

NSURL* urlEx = [NSURL URLWithString:#"Pacific_Map.png"];
NSData* mapExIMGData = [[NSData alloc] initWithContentsOfURL: urlEx];
UIImage* imgEx = [[UIImage alloc] initWithData:mapExIMGData];
mapImageViewEx.image = imgEx;
If I replace mapImageViewEx.image = imgEx; with mapImageViewEx.image = [UIImage imageNamed:#"Pacific_Map.png"]; it works, but I do not want to use imageNamed.
That's because imageNamed knows where to scan for the file, but initWithContentsOfURL expects the full path. use
NSString *imagePath = [[NSBundle mainBundle] pathForResource:#"Pacific_Map" ofType:#"png"];
NSURL* urlEx = [NSURL fileURLWithPath:imagePath];
NSData* mapExIMGData = [[NSData alloc] initWithContentsOfURL: urlEx];
UIImage* imgEx = [[UIImage alloc] initWithData:mapExIMGData];
mapImageViewEx.image = imgEx;
What's wrong with using imageNamed? Anyway, you could use initWithContentsofPath.
+ (UIImage *)imageWithContentsOfFile:(NSString *)path
Tell us more about what you are trying to accomplish. Good luck,
James
EDIT: Sorry, I assumed Pacific_Map.png was just a placeholder path. Like someone else posted, you need to indicate the full path if you're not going to use imageNamed.

Load image from server on a UIImageView in phone

I'm having a problem loading a remote image into a UIImageVIew...
It just doesn't show the image, may be i'm missing something...
I also use the described here but with the same results
How to load image from remote server on the UIImageView in iphone?
Can someone help me?
This is the code i'm using
Im getting the data from a xml and on the image element I have the full path
[[detailViewController detailImage] setImage:[UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString: [NSString stringWithFormat:#"%#", [[promoList objectAtIndex: promoIndex] objectForKey: #"image"]] ]]] ];
With this code the image are displayed correctly
[[detailViewController detailImage] setImage:[UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString: #"http://localhost/promos/preview/1.jpeg"]] ]];
Since the bottom example works as expected and besides the url string the example looks the same the problem should be with getting the url string. The problem is also that the code looks the same but it is quite hard to see. I would refactor the code to something like:
NSObject *urlObject = [[promoList objectAtIndex:promoIndex] objectForKey:#"image"];
NSString *urlString = [NSString stringWithFormat:#"%#", urlObject];
NSURL *url = [NSURL URLWithString:urlString];
NSData *imageData = [NSData dataWithContentsOfURL:url];
UIImage *image = [UIImage imageWithData:imageData];
[[detailViewController detailImage] setImage:image];
Then you can debug the statement properly and make sure that you get what you expect after each step.
Update
To remove newline and tabs you can:
NSString *urlString = [NSString stringWithFormat:#"%#", urlObject];
urlString = [urlString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
If urlObject already is a string, which it should be, then you can do:
NSString *urlString = [urlObject stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
which would make it a bit cleaner.
UIImage *img = [[UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:#"http://...."]]] retain];
if (img != nil)
{
[imageViewName setImage:img];
[img release];
}

How do you set a UIImage using an absolute URL?

I am trying to set the UIImage of a tableview cell to an absolute url, here's the code i have already:
NSString * imageURL = [[stories objectAtIndex:indexPath.row] objectForKey:#"images"];
NSURL *url = [NSURL URLWithString:imageURL];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data];
//set image
cell.imageView.image = img;
But for some reason this returns null as if the URL supplied is invalid. However i know this is not the case because i can make it work by typing one of the URLs as a string literal into the imageURL pointer and i know the code [[stories objectAtIndex:indexPath.row] objectForKey:#"images"] returns correct URLs as i printed the output to the log and it was fine.
Is there any reason why this would be happening that I'm clearly not seeing here?
You can use the absoluteURL method of NSURL and voila!
NSURL *url = [[NSURL URLWithString:imageURL] absoluteURL];

how can i display image from url?

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....
