I have Five buttons.On each button action.I have open gallery and choose an image.But the problem is on each button action same path is coming.
UIImage* image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
NSData* imageData = UIImagePNGRepresentation(image);
NSString * imageName = #"Myimage.png";
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
NSLog(#"fullPathToFile=%#",fullPathToFile); //important line
[imageData writeToFile:fullPathToFile atomically:NO];
Set global variable initially int countVal = 1;
NSString * imageName = [NSString stringWithformat:#"%d.png",countVal]; // Imgae_name set here
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
NSLog(#"fullPathToFile=%#",fullPathToFile); //important line
[imageData writeToFile:fullPathToFile atomically:NO];
count +=1; // Increment count here
I may be missing something, but it looks like you're using the same name for the image each time: Myimage.png. Every time the image will be saved inside the documents directory with that same name. Maybe add a tag to each button and use that to distinguish each of the 5 different images?
May be it will helpful for u
[picker dismissModalViewControllerAnimated:YES];
imageView.image= [info objectForKey:#"UIImagePickerControllerOriginalImage"];
NSData *webData = UIImagePNGRepresentation(imageView.image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:png];
[webData writeToFile:localFilePath atomically:YES];
NSLog(#"localFilePath.%#",localFilePath);
UIImage *image = [UIImage imageWithContentsOfFile:localFilePath];
OR
Use this code
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:#"savedImage.png"];
imageView.image= [info objectForKey:#"UIImagePickerControllerOriginalImage"];
NSData *webData = UIImagePNGRepresentation(imageView.image);
[imageData writeToFile:savedImagePath atomically:NO];
NSLog(#"localFilePath.%#",localFilePath);
If you still get it empty then try by checking if NSData is created properly
NSLog(#"webData.%#",webData);
OR
Try this: I hope defnetly it will be be helpful to you
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *img = [info objectForKey:UIImagePickerControllerEditedImage];
//you can use UIImagePickerControllerOriginalImage for the original image
//Now, save the image to your apps temp folder,
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:#"upload-image.tmp"];
NSData *imageData = UIImagePNGRepresentation(img);
//you can also use UIImageJPEGRepresentation(img,1); for jpegs
[imageData writeToFile:path atomically:YES];
//now call your method
[self uploadMyImageToTheWebFromPath:path];
}
Try to use below code which just edited to you answer
The problem is only with saving image name,try to save it with different name
The below code will help you in saving image with diffrent name
note: put the tag value to diffrent button(5 buttons) and call bello method in its target
-(void)saveImage:(UIButton*)sender{
UIImage* image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
NSData* imageData = UIImagePNGRepresentation(image);
NSString * imageName =[NSString stringWithFormat:#"Myimage%d.png",sender.tag];
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
NSLog(#"fullPathToFile=%#",fullPathToFile); //important line
[imageData writeToFile:fullPathToFile atomically:NO];
}
by this you can save image with different name

It is my save method :
-(NSString *)saveImage:(UIImage *)image
{
NSInteger RandomIndex = arc4random() % 1000;
NSString *randomImageName =[NSString stringWithFormat:#"Image%i.png",RandomIndex];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:randomImageName];
if ([[NSFileManager defaultManager] fileExistsAtPath:savedImagePath]) {
[[NSFileManager defaultManager] removeItemAtPath:savedImagePath error:nil];
NSLog(#"file removed from path");
}
NSLog(#"Saved Image Path : %#",savedImagePath);
NSData* imageData = UIImagePNGRepresentation (image);
[imageData writeToFile:savedImagePath atomically:YES];
self.teamLogo = savedImagePath;
return savedImagePath;
}
I try to load image and put into control :
NSData *myData = [NSData dataWithContentsOfFile:self.team.logo];
UIImage *selectedImage = [UIImage imageWithData:myData];
self.team.logo is from DB. I keep string in base. In debug mode i got this string :
/var/mobile/Containers/Data/Application/7CD69EC9-9C20-48EE-B611-FC2353BC31B0/Documents/Image364.png
and myData is still nil. Do you have idea why ?
Starting from IOS 8 layout of containers changed. So don't store full path to your DB. Instead just store your image name. For recalling the image use:
NSString *temp = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:#"Image364.png"];
NSData *myData = [NSData dataWithContentsOfFile:temp];
UIImage *selectedImage = [UIImage imageWithData:myData];
I hope it helps.
I'm not quite sure whats going wrong here, I'd really appreciate some help as I'm very stuck.
This is my imagePickerController
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithLong:customphoto1] forKey:#"customphoto1count"];
UIImage *button1Image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
pngData = UIImagePNGRepresentation(button1Image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"Button1image.png"]; //Add the file name
[pngData writeToFile:filePath atomically:YES]; //Write the file
[self dismissViewControllerAnimated:YES completion:NULL];
pngData = [NSData dataWithContentsOfFile:filePath];
UIImage *imageLoaded = [UIImage imageWithData:pngData];
[_button1 setImage:imageLoaded forState:UIControlStateNormal];
self.button1.clipsToBounds = YES;
self.button1.layer.cornerRadius = (self.button1.frame.size.width / 16);//half of the width
self.button1.layer.borderColor=[UIColor blackColor].CGColor;
self.button1.layer.borderWidth=1.0f;
[self dismissViewControllerAnimated:YES completion:NULL];
}
The above saves the image (as far as I believe) since _button1 is reading from imageLoaded
When the app closes and is reopened, this is the what calls the button to be displayed, and should load the picture from my NSData:
-(void)customButton1{
if (customphoto1 == 1) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"Button1image.png"]; //Add the file name
[pngData writeToFile:filePath atomically:YES];
pngData = [NSData dataWithContentsOfFile:filePath];
UIImage *imageLoaded1 = [UIImage imageWithData:pngData];
NSLog(#"%#", filePath);
// UIImage *imageload1 = [UIImage imageWithData:[newManagedObject valueForKey:#"imagesone"]];
[_button1 setImage:imageLoaded1 forState:UIControlStateNormal];
}
else {
button1ImageName = #"addnew";
}
}
Why is my image not loading?
Many thanks
Try this:
-(void)customButton1{
if (customphoto1 == 1) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"Button1image.png"];
UIImage *imageLoaded1 = [UIImage imagewithcontentsoffile:filePath];
NSLog(#"%#", filePath);
[_button1 setImage:imageLoaded1 forState:UIControlStateNormal];
}
else {
button1ImageName = #"addnew";
}
}
Debug: Check whether the filepath which is getting printed is correct or not. Open this path in Finder > CMD + Shift + G and paste the path (remove the file name from the path, use till folder level). Then check if that particular image is available in that folder or not.
Also in your didFinishPickingMediaWithInfo method, you are calling dismissViewControllerAnimated method two times, it should be once and at the end of method.
Hope this helps
Image was saving and loading alright all along - issue turned out to be with the buttons setImage function
In iOS 8, I am writing UIImages on the device using the code
NSString *documentsDirectory = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
documentsDirectory = [paths objectAtIndex:0];
NSString *pathString = [NSString stringWithFormat:#"%#/%#%ld",documentsDirectory, #"ProfileImage", (long)[[NSUserDefaults standardUserDefaults] integerForKey:#"PatientsId"]];
NSData *imageData = UIImageJPEGRepresentation(image, 40);////I have replaced it with UIImagePNGRepresentation as well
[imageData writeToFile: pathString atomically:YES];
The write to file is successful.
If I try to recover the image using the function,
NSArray *documentDirectories =
NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
// Get one and only document directory from that list
NSString *documentDirectory = [documentDirectories objectAtIndex:0];
NSString *pathString =[documentDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#%ld", #"ProfileImage", (long)[[NSUserDefaults standardUserDefaults] integerForKey:#"PatientsId"]]] ;
UIImage *image = [UIImage imageWithContentsOfFile: pathString];
The image is recovered.
However, if I restart the device, the images are not there anymore. The function [UIImage imageWithContentsOfFile: pathString] returns nil and if I use NSData *myData = [[NSData alloc] initWithContentsOfFile: pathString];, the myData is nil as well.
This procedure was working perfectly fine prior to iOS 8, however, it isn't working properly anymore. Can someone please guide me what is wrong with this?
First I stored image path from web service into SQLITE, and then I retrieve it back using local path. I am using NSMutableArray. I've successfully stored one image in NSDocumentDirectory, but I have one issue, How can I store more than one images in NSDocumentDirectory?
My code is,
if ([[[node childAtIndex:counter] name] isEqualToString:#"Column5"])
{
NSString *str = [[node childAtIndex:counter] stringValue];
[Col5 addObject:str];
NSString *myString = [Col5 componentsJoinedByString:#","];
NSString *aString = [NSString stringWithFormat:#"http://webserviceurl/%#",myString];
NSURL *url= [NSURL URLWithString:aString];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:strCol4];
UIImage *image = tmpImage;
NSData *imageData = UIImagePNGRepresentation(image);
[imageData writeToFile:savedImagePath atomically:NO];
}
For this line:
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:strCol4];
Just use a different path component.
I having trouble figuring out NSBundle & DocumentDirectory data, I have a Camera Picture "imageView" that I'm saving to the NSDocumentDirectoy and then want to retrieve it for attaching to an email,
Here the saving code:
- (IBAction)saveImage {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:#"savedImage.png"];
UIImage *image = imageView.image; // imageView is my image from camera
NSData *imageData = UIImagePNGRepresentation(image);
[imageData writeToFile:savedImagePath atomically:NO];
}
Here is the new getting data code:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *appFile = [documentsDirectory stringByAppendingPathComponent:#"savedImage.png"];
NSData *myData = [[[NSData alloc] initWithContentsOfFile:appFile] autorelease];
[picker addAttachmentData:myData mimeType:#"image/png" fileName:#"savedImage"];
- (IBAction)getImage {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:#"savedImage.png"];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
}
This should get you started!
Swift 3
// Create a URL
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first
let imageURL = documentsURL?.appendingPathComponent("MyImageName.png")
// save image to URL
let myImage = imageView.image! // or wherever you have your UIImage
do {
try UIImagePNGRepresentation(myImage)?.write(to: imageURL!)
} catch {}
// Use the URL to retrieve the image for sharing to email, social media, etc.
// docController.URL = imageURL
// ...
I force unwrapped some of the optionals for brevity. Use guard or if let in your code.
Because each iPhone app is in it's own sandbox, you don't have access to a device-wide documents folder. To attach an image to an email, save the image in your own documents folder. Try using [#"~/Documents" StringByExpandingTildeInPath] to get your local documents folder - that works for me. It looks like the technique you're using for attaching the image to an email is correct.
Hope that helps,
Try this one :
-(void)setProfilePic
{
NSArray *docpaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [docpaths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"Image.png"];
NSData *imgData = [[NSData alloc] initWithContentsOfURL:[NSURL fileURLWithPath:imagePath]];
UIImage *thumbNail = [[UIImage alloc] initWithData:imgData];
[profilePic_btn setBackgroundImage:thumbNail forState:UIControlStateNormal];
}
