File ios problems - unrecognized selector - iphone

Question

This is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
textBox = [[UITextField alloc] initWithFrame:CGRectMake(10, 50, 300, 40)];
[textBox setDelegate:self];
[self.view addSubview:textBox];
[textBox release];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(saveText) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Save" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[self.view addSubview:button];
NSFileManager *filemgr;
NSString *dataFile;
NSString *docsDir;
NSArray *dirPaths;
filemgr = [NSFileManager defaultManager];
// Identify the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"PATH---> %#",dirPaths);
docsDir = [dirPaths objectAtIndex:0];
// Build the path to the data file
dataFile = [docsDir stringByAppendingPathComponent: #"datafile.dat"];
// Check if the file already exists
if ([filemgr fileExistsAtPath: dataFile])
{
// Read file contents and display in textBox
NSData *databuffer;
databuffer = [filemgr contentsAtPath: dataFile];
NSString *datastring = [[NSString alloc] initWithData: databuffer encoding:NSASCIIStringEncoding];
textBox.text = datastring;
[datastring release];
}
[filemgr release];
[super viewDidLoad];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
- (void)saveText:(id)sender
{
NSLog(#"Text saved");
}
If I try executing this I am getting an error saying
"2013-02-18 12:43:46.194 FileExample[1475:207] -[FileExampleViewController saveText]: unrecognized selector sent to instance 0x682e730"
I am new to iOS and am not able to identify or understand or debut this error.

Change your this line
[button addTarget:self action:#selector(saveText) forControlEvents:UIControlEventTouchUpInside];
with this
[button addTarget:self action:#selector(saveText:) forControlEvents:UIControlEventTouchUpInside];
OR
do this
- (void)saveText // removed " :(id)sender "
{
NSLog(#"Text saved");
}
