I have used the below function to store images locally in a folder created in document directory
NSError *error;
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
// FOR STORING IMAGE INTO FOLDER CREATED IN DOCUMENT DIRECTORY
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"/ImagesFolder"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];
NSData* imageData = UIImagePNGRepresentation(imageView.image);
NSString* incrementedImgStr = [NSString stringWithFormat:#"Image%d.png",delegate.dirCountImages];
NSString* fullPathToFile2 = [dataPath stringByAppendingPathComponent:incrementedImgStr];
[imageData writeToFile:fullPathToFile2 atomically:NO];
However how do i retrieve images from that particular folder in document directory
-(NSMutableArray*)getPhotoFileNames:(NSString*)parentFolderName
{
NSString *path = [NSString stringWithFormat:#"%#/%#",[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES)objectAtIndex:0], parentFolderName];
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:nil];
NSEnumerator *enumerator = [dirContents objectEnumerator];
id fileName;
NSMutableArray *fileArray = [[NSMutableArray alloc] init];
while (fileName = [enumerator nextObject])
{
NSString *fullFilePath = [path stringByAppendingPathComponent:fileName];
NSRange textRangeJpg = [[fileName lowercaseString] rangeOfString:[#".png" lowercaseString]];
if (textRangeJpg.location != NSNotFound)
{
UIImage *originalImage = [UIImage imageWithContentsOfFile:fullFilePath];
[fileArray addObject:originalImage];
}
}
return fileArray;
}
Just need to have the full path and use this method. [[UIImage alloc]initWithContentsOfFile: <#path#>] remember to release the image after if you are not using ARC.
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100,100,100,100)];
imageView.image = [[UIImage alloc] initWithData:myImage];
[myView addSubview:imageView];
or see that link http://www.iphonedevsdk.com/forum/iphone-sdk-development/23840-placing-image-url-image-view.html
Perhaps this will help you.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
documentsDirectory = [documentsDirectory stringByAppendingPathComponent:#"Images"];
documentsDirectory = [documentsDirectory stringByAppendingPathComponent:#"Image.png"];
[cell.songImageView setImage:[UIImage imageWithContentsOfFile:documentsDirectory]];

Loading an Image from documents directory
(6 answers)
Closed 9 years ago.
I want to display image saved in the documents folder problem is that it returns file name but it does not show image in the image View
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString*patientlastName;
NSString*test=#"nicej";
patientlastName=[test stringByReplacingOccurrencesOfString:#" " withString:#""];
NSString * filePath = [NSString stringWithFormat:#"%#/Documents//%#.png", NSHomeDirectory(),patientlastName];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:filePath];
if (fileExists == 0)
{
NSLog(#"File is Not exists");
appDelegate.imageURL=#"File Not Exists";
}
NSString *userfile=[NSString stringWithFormat:#"%#",patientlastName];
appDelegate.imageURL=userfile;
PictureDisplayViewController *targetController = [[PictureDisplayViewController alloc] initWithNibName:#"PictureDisplayViewController" bundle:nil];
targetController.modalPresentationStyle = UIModalPresentationFullScreen;
[self.splitViewController presentViewController:targetController animated:YES completion:nil];
In PictureDisplayViewController
imageView.image=[UIImage imageNamed:#"nicej.png"];
try this code:
save image in this path:
NSFileManager *fileMan = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *str= [NSString stringWithFormat:#"%#.png",patientlastName];
NSString *Image_filePath=[documentsDirectory stringByAppendingPathComponent:str];
NSData *imagedata=UIImagePNGRepresentation(yourimage);
[fileMan createFileAtPath:[Image_filePath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] contents:imagedata attributes:nil];
get image path:
NSString* fileName = [NSString stringWithFormat:#"%#.png",patientlastName}
NSArray *arrayPaths =
NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory,
NSUserDomainMask,
YES);
NSString *path = [arrayPaths objectAtIndex:0];
NSString* pdfFileName = [path stringByAppendingPathComponent:fileName];
UIImage *image1=[UIImage imageWithContentsOfFile:pdfFileName];
imageView.image=image1;
//suppose imgpath is path of your image in doument directory then use these two lines of code.
NSData *imgData = [NSData dataWithContentsOfFile:imgPath];
imageView.image = [[UIImage alloc] initWithData:imgData];
In PictureDisplayViewController, you are loading image with imageNamed method that actually doesn't work until you have image with the same name into your bundle.
you can load image like as follow...
In PictureDisplayViewController you already have path for the image than
imageView.image= [UIImage imageWithContentsOfFile:filePathWithName];
I modify your code :
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString*patientlastName;
NSString*test=#"nicej";
patientlastName=[test stringByReplacingOccurrencesOfString:#" " withString:#""];
NSString * filePath = [NSString stringWithFormat:#"%#/Documents//%#.png", NSHomeDirectory(),patientlastName];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:filePath];
if (fileExists == 0)
{
NSLog(#"File is Not exists");
appDelegate.imagePath=#"";
}
else
{
appDelegate.imagePath=filePath;
}
PictureDisplayViewController *targetController = [[PictureDisplayViewController alloc] initWithNibName:#"PictureDisplayViewController" bundle:nil];
targetController.modalPresentationStyle = UIModalPresentationFullScreen;
[self.splitViewController presentViewController:targetController animated:YES completion:nil];
In PictureDisplayViewController
if(appDelegate.imagePath)
{
UIImage *image=[UIImage imageWithContentsOfFile:appDelegate.imagePath];
}
else
{
imageView.image=[UIImage imageNamed:#"default.png"];
}
default.png is a default png pic in your bundle resource
I have folder named "2" in document directory. Now in folder "2", I have five images named 0.png, 1.png, 2.png, 3.png and 4.png. I want to retrieve these images and save into an array. I have code but it returns only one image.
int b=2;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d/0.png",b]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
NSLog(#"%#",getImagePath);
imge.image=img;
Just use NSFileManager, something like this:
[[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:&error];
It will give you an array with all the file paths for all files in the given path.
This is how you load the images from the array of URLs.
NSArray *paths = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:&error];
for (NSURL *url in paths)
{
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
}
You should loop through the images.
int b=2;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSMutableArray *images = [NSMutableArray arrayWithCapacity:5];
for (int i = 0; i < 5; i++)
{
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d/%d.png",b, i]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
[images addObject:img];
NSLog(#"%#",getImagePath);
imge.image=img;
}
Instead of hardcoding the count and names of the image files, as Dominik suggested you should use contentsOfDirectoryAtPath:error: to get the list of files in that directory.
NSError *error = nil;
NSArray *imageFileNames = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d",b]] error:&error];
I want to make multiple directories I do not know how. This is my code up till now .
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"tops",#"bottoms",#"right" ];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
}
I want to have 4 directories that are named tops bottoms right and left however it does not work if I do it in the above way.. Is there a way to make multiple directories using this code? or is my code wrong? Thanks!
Try this code.
To create directories as you asked.
NSArray *directoryNames = [NSArray arrayWithObjects:#"tops",#"bottoms",#"right",#"left",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
}
To use your created directories anywhere in your app.
NSArray *directoryNames = [NSArray arrayWithObjects:#"tops",#"bottoms",#"right",#"left",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
// This will return the folder name in the 0 position. In yours "tops"
NSString *topDirPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:0]];
// This will return the file path in your "tops" folder
NSString *filePath = [topDirPath stringByAppendingPathComponent:#"MYIMAGE"];
To store an image file
NSData *imageDataToStore = UIImagePNGRepresentation(image);
[imageDataToStore writeToFile:filePath atomically:YES];
To retrieve an image file
// Convert the file into data and then into image.
NSData *imageData = [[NSData alloc] initWithContentsOfFile:filePath];
UIImage *yourImage = [UIImage imageWithData:imageData];
In my document directory one image is their, with name Image1.
I want copy same image with name Image2 in document directory folder.
Please, suggest me how can i do that?
refer a following code.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [paths objectAtIndex:0];
NSString *imagePath1= [documentDirectory stringByAppendingPathComponent:#"image1.png"];
NSString *imagePath2= [documentDirectory stringByAppendingPathComponent:#"image2.png"];
[[NSFileManager defaultManager] copyItemAtPath:imagePath1 toPath:imagePath2 error:nil];
Get he data from first image and save the same data with another name like:
NSData *data = UIImageJPEGRepresentation(image1, 1.0);
NSString *str=#"image2.png"
NSString *fileName = [[stringPath stringByAppendingFormat:#"/"] stringByAppendingFormat:str];
NSString *stringPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
[data writeToFile:fileName atomically:YES];
I have two mathed of Fatch image and save image:
You fatch image that save in Document directory and then pass it to save image with different name:
-(UIImage *)loadImage:(NSString *)name
{
NSString* documentsDirectory=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES) objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:name];
UIImage *res = [UIImage imageWithContentsOfFile:fullPath];
return res;
}
-(void)saveImage:(UIImage *)image withName:(NSString *)name
{
NSData *data = UIImageJPEGRepresentation(image, 1);
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString* documentsDirectory=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES) objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:name];
[fileManager createFileAtPath:fullPath contents:data attributes:nil];
}
In a App images stored in Document Directory Folder,
I wanted Particular image display in Image view,
How that image Display in Image View from the Document Directory ?
sample code:
- (NSString *)applicationDocumentsDirectory {
return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}
-(void)loadimage{
NSString *workSpacePath=[[self applicationDocumentsDirectory] stringByAppendingPathComponent:#"your image-name"];
UIImageView *myimage=[UIImageView alloc] initWithFrame:CGRectMake(0,0,20,20)];
myimage.image=[UIImage imageWithData:[NSData dataWithContentsOfFile:workSpacePath]];
[self.view addSubView:myimage];
[myimage release];
}
TNQ
You can achieve it, By knowing the names of your images, so while you are storing your image you need to store some information of these images in database,(or some where you can use it), then fetch name of image from data source, and work as follows:
NSString *str = [NSString stringWithFormat:#"%#.jpg",[myGlobleArrayOfImageNames objectAtIndex:imageCounter]];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullImgNm=[documentsDirectory stringByAppendingPathComponent:[NSString stringWithString:str]];
[mainSlideShowImageView setImage:[UIImage imageWithContentsOfFile:fullImgNm]];
Here you can take UIImageView in your View and add it to the view and do the same like as follows:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imageFilePath;
NSError *err;
imageFilePath = [documentsDirectory stringByAppendingPathComponent:#"image1.png"];
UIImageView *objImageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 100, 100)];
objImageView.image = [UIImage imageWithContentsOfFile: imageFilePath];
[self.view addSubVIew:objImageView.image];
[objImageView release];
Please let me know if you still need any help.
NSArray *directoryPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *imagePath = [directoryPath objectAtIndex:0];
imagePath= [imagePath stringByAppendingPathComponent:#"imagename.png"];
NSData *data = [NSData dataWithContentsOfFile:imagePath];
UIImage *img = = [UIImage imageWithData:data];
you can display this image to uiimageview
you need following lines of code to get UIImage from documents directory
-(UIImage*)getImage:(NSString *)strImageName
{
NSString *documentDirectory=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *imagePath=[documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"/%#",strImageName]];
UIImage *image=[UIImage imageWithContentsOfFile:imagePath];
return image;
}
Call above function and use UIImage object to set anywhere you want.
You can also write this method in a common class to use it anywhere.
Adding to these answers I find its good practice to check if the file exists like so...
NSString *directory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *file = [directory stringByAppendingPathComponent#"my_image.jpg"];
if ([[NSFileManager defaultManager] fileExistsAtPath:file]) {
self.myimageview = [UIImage imageWithData:[NSData dataWithContentsOfFile: file]];
}
Simple Use This Code
NSFileManager *filemgr =[NSFileManager defaultManager];
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *docsDir = [dirPaths objectAtIndex:0];
NSString *dataPath = [docsDir stringByAppendingPathComponent:#"/yourdirectory/image.jpg"];
NSData *imgData = [[NSData alloc] initWithContentsOfURL:[NSURL fileURLWithPath:dataPath]];
self.imageview.image = [[UIImage alloc] initWithData:imgData];
