I am gettting images from documents directory. it's succesfully getiing. but when it's load on table it appear same images on table.
arrayOfImages = [[NSMutableArray alloc]init];
NSString *stringPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
// NSString *stringPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSLog(#"%#",documentsDirectory);
filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(#"files array %#", filePathsArray);
for(i=0;i<[filePathsArray count];i++)
{
NSString *strFilePath = [filePathsArray objectAtIndex:i];
NSLog(#"%#",strFilePath);
if ([[strFilePath pathExtension] isEqualToString:#"JPG"] || [[strFilePath pathExtension] isEqualToString:#"png"] || [[strFilePath pathExtension] isEqualToString:#"PNG"])
{
NSString *imagePath = [[stringPath stringByAppendingFormat:#"/"] stringByAppendingFormat:strFilePath];
NSLog(#"%#",imagePath);
NSData *data = [NSData dataWithContentsOfFile:imagePath];
if(data)
{
UIImage *image = [UIImage imageWithData:data];
NSLog(#"%#",image);
[arrayOfImages addObject:image];
NSLog(#"%#",arrayOfImages);
}
}
}
For Table i m calling this code
saveImageView = [[UIImageView alloc]initWithFrame:CGRectMake(10.0, 10.0, 100.0, 80.0)];
[saveImageView setImage:[arrayOfImages objectAtIndex:indexPath.row]];
[cell.contentView addSubview:saveImageView];
Try this in your cellForRowAtIndexPath method.
static NSString *CellIdentifier = #"Cell";
UIImageView *saveImageView = [[UIImageView alloc]initWithFrame:CGRectMake(10.0, 10.0, 100.0, 80.0)];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ; // You cell initialization
saveImageView.tag = 1000;
[cell.contentView addSubview:saveImageView];
}
((UIImageView *)[cell.contentView viewWithTag:1000]).image = [arrayOfImages objectAtIndex:indexPath.row];

I am using sqlite db to save image path of document directory. Here is my code:
NSData * imageData = UIImageJPEGRepresentation(image, 0.8);
NSLog(#"Image data length== %d",imageData.length);
if (imageData != nil)
{
UIImage *resizedImg = [self scaleImage:[UIImage imageWithData:imageData] toSize:CGSizeMake(150.0f,150.0f)];
NSData * imageData = UIImageJPEGRepresentation(resizedImg, 0.2);
NSLog(#"*** Image data length after compression== %d",imageData.length);
NSString *nameofimg=[NSString stringWithFormat:#"%#",resizedImg];
NSString *substring=[nameofimg substringFromIndex:12];
NSString *new=[substring substringToIndex:7];// Get image name
NSArray *path=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentdirectory=[path objectAtIndex:0];
NSString *newFilePath = [NSString stringWithFormat:[documentdirectory stringByAppendingPathComponent: #"/%#.png"],new];
[imageData writeToFile:newFilePath atomically:YES];
imgpath=[[NSString alloc]initWithString:newFilePath];
NSLog(#"doc img in img method === %#",imgpath);
}
databasepath=[app getDBPath]; // i have this method in delegate
if (sqlite3_open([databasepath UTF8String], &dbAssessor) == SQLITE_OK)
{
NSString *selectSql = [NSString stringWithFormat:#"insert into imagetb(imagename,image) VALUES(\"%#\",\"%#\") ;",yourImgName,imgpath];
NSLog(#"Query : %#",selectSql);
const char *sqlStatement = [selectSql UTF8String];
sqlite3_stmt *query_stmt;
sqlite3_prepare(dbAssessor, sqlStatement, -1, &query_stmt, NULL);
if(sqlite3_step(query_stmt)== SQLITE_DONE)
{
NSLog(#"home image updated. :)");
app.houseImage=imgpath;
}
else
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Sorry" message:#"Failed To Save Home Image." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
sqlite3_finalize(query_stmt);
}
sqlite3_close(dbAssessor);
These code save the image in document directory and path in sqlite. Now I want to show image from documents directory to imageview. How to do that? Any idea?
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];
}
NSString *str = [NSString stringWithFormat:#"%#.jpg",[YourImageArray objectAtIndex:imageCounter]];
or
NSString *str=[[self applicationDocumentsDirectory] stringByAppendingPathComponent:#"YourImageName"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullImgNm=[documentsDirectory stringByAppendingPathComponent:[NSString stringWithString:str]];
[ImageView setImage:[UIImage imageWithContentsOfFile:fullImgNm]];
Hope Your Helpfull
NSString *docDirPath = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] objectAtIndex:0];
NSString *filePath = [docDirPath stringByAppendingFormat:#"myFile.png"];
UIImage *image = [UIImage imageWithContentsOfFile:filePath];
[imageView setImage:image];
If the entire path is stored in the sqlite then you just need to use this
NSString *imapeFilePath = PATH_FROM_DATABASE;
self.imageView.image = [UIImage imageWithContentsOfFile:imapeFilePath];
if the file name is stored in the database then use the following
NSString *imapeFilePath =[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:YOUR_IMAGE_NAME];
self.imageView.image = [UIImage imageWithContentsOfFile:imapeFilePath];
I'm new to iPhone development, I have used UIImagePickerController to capture the image manually, but i want to capture the image automatically, Is it possible to do that.
please help me.
Thanks in advance
Try This. In this I have saved the screen shot in photos album
-(void)screenShotCapture
{
//-- Screen Capture --------------------------------------------------------------------//
UIImage *image = nil;
UIGraphicsBeginImageContext(loginBgImgVw.frame.size);
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"MM-dd-yyyy hh:mm:ss"];
[formatter setTimeZone:[NSTimeZone localTimeZone]];
NSString *dateToday = [formatter stringFromDate:[NSDate date]];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(375, 0, 600, 44)];
[label setText:dateToday];
NSString *fileNameStr = [NSString stringWithFormat:#"%#_Login_%#",providerIdStr,dateToday];
[label setText:fileNameStr];
label.backgroundColor = [UIColor clearColor];
[loginBgImgVw addSubview:label];
[formatter release];
loginBgImgVw.frame = CGRectMake(10, 0, 1006, 669);
[loginBgImgVw.layer renderInContext: UIGraphicsGetCurrentContext()];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[label removeFromSuperview];
//=--
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docspath = [paths objectAtIndex:0];
NSLog(#"path=--%#",paths);
NSString *dataPath = [docspath stringByAppendingPathComponent:[NSString stringWithFormat:#"ProviderID_%#",providerIdStr]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
{
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil];
}
NSString *savedImagePath = [dataPath stringByAppendingPathComponent:#"Login_Provider.png"];
NSData *imageData = UIImageJPEGRepresentation(image, 0.2);
if ([screenCapturNameAry count] != 0)
{
if ([screenCapturNameAry containsObject:#"Login"])
{
[imageData writeToFile:savedImagePath atomically:NO];
}
}
UIImageWriteToSavedPhotosAlbum([self loadImage:#"Login_Provider"],self,#selector(image:didFinishSavingWithError:contextInfo:),NULL);
//--------------------------------------------------------------------------------------//
}
- (void)image:(UIImage*)image didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo
{
if (error == nil)
{
NSLog(#"Login Image saved successfully.");
}
else
{
NSLog(#"Error occurred:%#",[error localizedDescription]);
}
}
You can get the saved image using following method
- (UIImage*)loadImage:(NSString*)imageName
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"ProviderID_%#",providerIdStr]];
NSString *fullPath = [dataPath stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.png",imageName]];
return [UIImage imageWithContentsOfFile:fullPath];
}
To take the screenshot you can use the following code.
UIGraphicsBeginImageContext(self.window.bounds.size);
[self.window.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * data = UIImagePNGRepresentation(image);
[data writeToFile:#"screen.png" atomically:YES];
For Ratina display device you have to check:
if ([[UIScreen mainScreen] respondsToSelector:#selector(scale)])
UIGraphicsBeginImageContextWithOptions(self.window.bounds.size, NO, [UIScreen mainScreen].scale);
else
UIGraphicsBeginImageContext(self.window.bounds.size);
As my above screen shot show that I want to show Two values in Each cell of Tableview. I can do it if I have the data which I want to show in these labels of Cell in the same Class,but problem for me is I am try to getting both these labels from other view or other class using (NSDocumentDirectory, NSUserDomainMask, YES) so for I got success to show one value as my screenshot show ,but the other part which consist of current data and time Display is still problem for me.Now here is my code which i try so for.
NSString *fina = [NSString stringWithFormat:#"%#",mySongname];
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir = [dirPaths objectAtIndex:0];
NSString *soundFilePath = [docsDir stringByAppendingPathComponent:#"MyRecordings"];
if (![[NSFileManager defaultManager] fileExistsAtPath:soundFilePath])
[[NSFileManager defaultManager] createDirectoryAtPath:soundFilePath withIntermediateDirectories:NO attributes:nil error:nil];
soundFilePath = [soundFilePath stringByAppendingPathComponent:fina];
recordedTmpFile = [NSURL fileURLWithPath:soundFilePath];
recorder = [[ AVAudioRecorder alloc] initWithURL:recordedTmpFile settings:recordSetting error:&error];
[recorder setDelegate:self];
[recorder prepareToRecord];
[recorder record];
[recordSetting release];
The above part of Code works fine it display the value in Tableview Cell that my screenshow.Now in same function I am try to getting the data to show it in red part which is my UILabel in Tableview Cell using Below Code.
NSDate* now = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd:MMM:YY_hh:mm:ss a"];
NSString *file= [dateFormatter stringFromDate:now];
NSLog(#"myfinaldate:%#",file);
Now i want to save this date value in same directory which i use above and to show it red parts of UITableview .
Now here is my Code where i use this Tableview and getting these document directory value.
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentPath = [documentsDirectory stringByAppendingPathComponent:#"MyRecordings"];
directoryContent = [[NSFileManager defaultManager] directoryContentsAtPath:documentPath];
NSLog(#"file found %i",[directoryContent count]);
[directoryContent retain];
[self.tableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
static NSInteger StateTag = 1;
static NSInteger CapitalTag = 2;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UILabel *capitalLabel = [[UILabel alloc] initWithFrame:CGRectMake(2, 2, 80, 20)];
//capitalLabel.text=#"mydata";
capitalLabel.backgroundColor=[UIColor redColor];
capitalLabel.tag = CapitalTag;
[cell.contentView addSubview:capitalLabel];
[capitalLabel release];
UILabel *stateLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 22, 310, 20)];
stateLabel.tag = StateTag;
[stateLabel setFont:[UIFont systemFontOfSize:14]];
stateLabel.adjustsFontSizeToFitWidth=YES;
[cell.contentView addSubview:stateLabel];
[stateLabel release];
}
UILabel * stateLabel = (UILabel *) [cell.contentView viewWithTag:StateTag];
//UILabel * capitalLabel = (UILabel *) [cell.contentView viewWithTag:CapitalTag];
stateLabel.text = [directoryContent objectAtIndex:indexPath.row];
//capitalLabel.text = [directoryContent1 objectAtIndex:indexPath.row];
return cell;
}
Now I am trying to summarize the problem.
How we can save the date and time value in same directory and then how to show here in Red part of UITableview Cell?
capitalLabel is my Redpart of Cell to show date and time which is problem.
stateLabel all ready show the values. so no problem with this label. Any help will be appreciated.
just do this....
you can set NSCachesDirectory to NSDocumentDirectory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:yourComponent];
// NSLog(#"Path : %#",writableDBPath);
NSMutableDictionary *plistArr = [[NSMutableDictionary alloc] initWithContentsOfFile:writableDBPath];
So Im making a two UIscrollview in my view. I'm using Ray Wenderlich's Custom Image Picker. But when I load it, only shows 1 imagepicker. I want to be able to load two image picker. I think Im doing something wrong with initWithCoder part. Cant seem to initialize it properly. Is it possible to have two ivars self. Sorry kinda new to iphoneDev. Thanks for your help.
Here's my whole implementation:

_images2 = [[NSMutableArray alloc] init];
_thumbs2 = [[NSMutableArray alloc] init];
}

In your createScrollView2 method, you alloc self.slotBg2, but then only reference self.slotBg when adding to your view. Then you add your scrollview2 to the original slotBg.
The following is the code I am using to display image in the table view and its name. It works fine however when we have lot of images inside the folder the app crashes. Any help is greatly appreciated.
