Question

Hi I am developing an iPad app that application needs to take screenshots automatically and images should be saved in the name of screen name long with the current date and current time which is in the device. Someone help me to do this.

I have tried the following code.In that code Screenshot is taken and i will print the name in label in that view. But in the label time is not accurate so i would like to save the image in the name of screen name appended by time.

        //-- 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(100, 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.layer renderInContext: UIGraphicsGetCurrentContext()];     
image = UIGraphicsGetImageFromCurrentImageContext();        
UIGraphicsEndImageContext();        

//=--

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);
[imageData writeToFile:savedImagePath atomically:NO];

UIImageWriteToSavedPhotosAlbum(image,self,@selector(image:didFinishSavingWithError:contextInfo:),NULL);

//--------------------------------------------------------------------------------------//

You need to change your date formatter as,

[formatter setDateFormat:@"MM-dd-yyyy HH:mm:ss"];

MM is for representing month and mm for minutes.
