Get Image from server - ios

Question

I am getting responseObject like this
responseObject =
{
"img": "images/ProfileImage/defaultImg.jpg",
}
I have to store this image in app folder. Is there any way to do this.

Answer 1

The path is incomplete
You need to append base URL before "images/ProfileImage/defaultImg.jpg"
Then
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSString *urlToDownload = BaseURL + "images/ProfileImage/defaultImg.jpg";
NSURL *url = [NSURL URLWithString:urlToDownload];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if (urlData)
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"defaultImg.png"];
//saving is done on main thread
dispatch_async(dispatch_get_main_queue(), ^{
[urlData writeToFile:filePath atomically:YES];
NSLog(#"File Saved !");
});
}
});

Here is the code for downloading image and store into a local i.e "Document" directory in iOS app folder
In below code urlString is the url of image.
dispatch_queue_t downloadThumbNail = dispatch_queue_create("com.download.thumbnail", NULL);
dispatch_async(downloadThumbNail, ^
{
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]];
UIImage *imageThumb = [UIImage imageWithData:imageData];
dispatch_async(dispatch_get_main_queue(),
^{
NSString *str = #“filename.png”;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *filePath = [documentsPath stringByAppendingPathComponent:str];
NSData *pngData = UIImagePNGRepresentation(imageThumb);
[pngData writeToFile:filePath atomically:YES];
});
});
Enjoy codeing.
