Question

I am Working on Recording Application.in This Application i Save my Recording with my own Text and it also Save the Recording with Current Date and Time.As my below Code show

-(IBAction)RecButtonPress:(id)sender
{
    NSLog(@"Song name:%@",mySongname);
    NSMutableDictionary* recordSetting = [[NSMutableDictionary alloc] init];
    [recordSetting setValue :[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey];
    [recordSetting setValue:[NSNumber numberWithFloat:44000.0] forKey:AVSampleRateKey]; 
    [recordSetting setValue:[NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey];
    [recordSetting setValue: [NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey];
    [recordSetting setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsBigEndianKey];
    [recordSetting setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsFloatKey];
    NSDate* now = [NSDate date];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"dd:MMM:YY_hh:mm:ss a"];
    NSString *file= [dateFormatter stringFromDate:now];
    NSString *fina=[file stringByAppendingString: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];
    NSLog(@"Uf:%@",recordedTmpFile);
    recorder = [[ AVAudioRecorder alloc] initWithURL:recordedTmpFile settings:recordSetting error:&error];
    [recorder setDelegate:self];
    [recorder prepareToRecord];
    [recorder record];
        [recordSetting release];
       [dateFormatter release];
}

Now After Saving Recording When i goes to SaveRecording Class Where actually i Show all these Recording in Tableview.here my Code is

- (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]);
NSLog(@"arraydata: %@", directoryContent );
[directoryContent retain];
[self.tableView reloadData];
 }

And After That i Assign “directoryContent” Which is my NSMutablArray To UITableview.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
  return [directoryContent count];
}

//////////////////////////////////////////////////////////////////////////////////////////////

- (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, 120, 20)];
    //capitalLabel.text=@"mydata";
    capitalLabel.backgroundColor=[UIColor redColor];
    capitalLabel.tag = CapitalTag;
    [capitalLabel setFont:[UIFont systemFontOfSize:9]];
    [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 = [datesaving objectAtIndex:indexPath.row];

return cell;
}

And Finaly my UITableView is Look like this Below ScreenShot

My All this Brief discussion purpose is that as my Screen shot show That UITableview Cell Show my Text and Current date and Time.Now i want to Split this directoryContent Array data into Two prats.The part which Consist of Current date and time i want to Assign it capitalLabel which is redpart of Cell in UITableview And Text to stateLabel Which is Below part of Cell in UITableview.Any help will be Appriated.Thanks in Advance.

Answer 1

First you need to append your string like this

NSString *file3 = [file stringByAppendingString:@"+"];


NSString *fina= [file3 stringByAppendingString:mySongname];

after that you need to seperate it like

NSArray *Array = [str componentsSeparatedByString:@"+"]; 
NSLog(@"myindex0str:%@",[Array objectAtIndex:0]); 
NSLog(@"myindex1str:%@",[Array objectAtIndex:1]);

so you will get the both time and songname individually.
