Convert NSData To UIImage - ios

Question

First of all I am selecting some images in one listingstep1view and passing those UIImages other View Controller by using sharedInstance.
ListingStep1Viewcontroller:
- (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info
{
[self dismissViewControllerAnimated:YES completion:nil];
for (UIView *v in [_scrollView subviews]) {
[v removeFromSuperview];
}
NSLog(#"info :%#", info);
CGRect workingFrame = _scrollView.frame;
workingFrame.origin.x = 0;
NSMutableArray *tempArray =[[NSMutableArray alloc] init];
NSMutableArray *images = [NSMutableArray arrayWithCapacity:[info count]];
for (int i =0; i<info.count; i++) {
NSDictionary *dict = [info objectAtIndex:i];
if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypePhoto){
if ([dict objectForKey:UIImagePickerControllerOriginalImage])
{
UIImage* image = [dict objectForKey:UIImagePickerControllerOriginalImage];
[iPhoneXMPPAppDelegate load_uploadingImage:[image fixOrientation]];
NSData* data = UIImageJPEGRepresentation([iPhoneXMPPAppDelegate get_upload_image], 1.0f);
//NSString *encodedImage = [data base64Encoding];
[Base64 initialize];
self.convertedImage=[[UIImage alloc]initWithData:data];
//self.convertedImage=[UIImage imageWithData:data];
NSLog(#"converted Data To Image= %#",self.convertedImage);
NSString *strEncoded = [Base64 encode:data];
strEncoded = [strEncoded stringByReplacingOccurrencesOfString:#"+" withString:#"%2B"];
[tempArray addObject:strEncoded];
[images addObject:image];
UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
[imageview setContentMode:UIViewContentModeScaleAspectFit];
imageview.frame = workingFrame;
[_scrollView addSubview:imageview];
workingFrame.origin.x = workingFrame.origin.x + workingFrame.size.width;
} else {
NSLog(#"UIImagePickerControllerReferenceURL = %#", dict);
}
}
else if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypeVideo){
if ([dict objectForKey:UIImagePickerControllerOriginalImage]){
UIImage* image=[dict objectForKey:UIImagePickerControllerOriginalImage];
[images addObject:image];
UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
[imageview setContentMode:UIViewContentModeScaleAspectFit];
imageview.frame = workingFrame;
[_scrollView addSubview:imageview];
workingFrame.origin.x = workingFrame.origin.x + workingFrame.size.width;
} else {
NSLog(#"UIImagePickerControllerReferenceURL = %#", dict);
}
} else {
NSLog(#"Uknown asset type");
}
}
self.chosenImages = images;
[[ListingStep2Model sharedInstance]setImagesAssetArray:tempArray];
//[[ListingStep2Model sharedInstance]setConvertedImage:self.convertedImage.image];
[_scrollView setPagingEnabled:YES];
[_scrollView setContentSize:CGSizeMake(workingFrame.origin.x, workingFrame.size.height)];
}
ListingStep5viewcontoller:
for (int i = 0; i < [[[ListingStep2Model sharedInstance] imagesAssetArray]count]; i++) {
NSMutableArray *images = [NSMutableArray arrayWithCapacity:[[[ListingStep2Model sharedInstance] imagesAssetArray]count]];
//UIImage*imageTodata=[[ListingStep2Model sharedInstance] convertedImage];
NSLog(#"Data Imges:%#", [[[ListingStep2Model sharedInstance] imagesAssetArray] objectAtIndex:i]);
//NSLog(#"Data Imges:%#", imageTodata);
NSDictionary *dict;
if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypePhoto){
if ([dict objectForKey:UIImagePickerControllerOriginalImage])
{
{
UIImage* image = [dict objectForKey:UIImagePickerControllerOriginalImage];
[iPhoneXMPPAppDelegate load_uploadingImage:[image fixOrientation]];
NSData* data = UIImageJPEGRepresentation([iPhoneXMPPAppDelegate get_upload_image], 1.0f);
//UIImageView *imgv = [[UIImageView alloc]init];
[Base64 initialize];
NSString *strEncoded = [Base64 encode:data];
strEncoded = [strEncoded stringByReplacingOccurrencesOfString:#"+" withString:#"%2B"];
NSMutableDictionary *param = [NSMutableDictionary dictionary];
[param setObject:strEncoded forKey:[NSString stringWithFormat:#"image%d",i]];
}
} else {
NSLog(#"UIImagePickerControllerReferenceURL = %#", dict);
}
}
}
[iPhoneXMPPAppDelegate startIndicator];
NSMutableArray *totalrequest = [[NSMutableArray alloc] init];
[totalrequest addObject:param];
[RequestAndResponseHandlers helparucommonRequestAndResponseHandlerWithParam:[NSDictionary dictionaryWithObjectsAndKeys:totalrequest,#"request",nil] methodName:methodName completionHandler:^(NSDictionary *response) {
NSLog(#"Response :%#", response);
if ([[response valueForKeyPath:#"response.httpCode"] integerValue]==200) {
[[iPhoneXMPPAppDelegate appdelegate] navigateTo:[iPhoneXMPPAppDelegate publicView ]];
}
else {
[iPhoneXMPPAppDelegate alertWithTitle:#"Alert" message:#"Please try again!"];
}
[iPhoneXMPPAppDelegate stopIndicator];
[self.containerTbl reloadData];
}];
}
Output is in NSData Format:

Answer 1

First you need to change the Base64string to NSData and then you can easily convert to UIImage. Here are the steps:
(1) Convert Base64String to NSData using the NSData+Base64 files.
NSData *imageData = [NSData dataFromBase64String:originalString];
(2) Now you can convert the NSData to Image as follows:
UIImage *newImage = [UIImage imageWithData:imageData];
