Xcode Dismiss Keyboard Login Screen - ios

Question

I'm working on an application that has a functioning keyboard with editing capabilities. In the mainViewController.m file, I am able to properly hide the keyboard with the following line of code:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
[super touchesBegan:touches withEvent:event];
}
After completing the main functionality of the application, I've created a simple login screen. However, the same code as above is not working in the loginScreen.m file.
#implementation LoginScreen
-(void)viewDidLoad {
[super viewDidLoad];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
[super touchesBegan:touches withEvent:event];
}
#pragma mark - View lifecycle
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(IBAction)btnLoginRegisterTapped:(UIButton*)sender
{
//form fields validation
if (fldUsername.text.length < 4 || fldPassword.text.length < 4) {
[UIAlertView error:#"Enter username and password over 4 chars each."];
return;
}
//salt the password
NSString* saltedPassword = [NSString stringWithFormat:#"%#%#", fldPassword.text, kSalt];
// Check for name/pw length
//prepare the hashed storage
NSString* hashedPassword = nil;
unsigned char hashedPasswordData[CC_SHA1_DIGEST_LENGTH];
//hash the pass
NSData *data = [saltedPassword dataUsingEncoding: NSUTF8StringEncoding];
if (CC_SHA1([data bytes], [data length], hashedPasswordData)) {
hashedPassword = [[NSString alloc] initWithBytes:hashedPasswordData length:sizeof(hashedPasswordData) encoding:NSASCIIStringEncoding];
} else {
[UIAlertView error:#"Password can't be sent"];
return;
}
//check whether it's a login or register
NSString* command = (sender.tag==1)?#"register":#"login";
NSMutableDictionary* params =[NSMutableDictionary dictionaryWithObjectsAndKeys:
command, #"command",
fldUsername.text, #"username",
hashedPassword, #"password",
nil];
//make the call to the web API
[[API sharedInstance] commandWithParams:params
onCompletion:^(NSDictionary *json) {
//result returned
NSDictionary* res = [[json objectForKey:#"result"] objectAtIndex:0];
if ([json objectForKey:#"error"]==nil && [[res objectForKey:#"IdUser"] intValue]>0) {
[[API sharedInstance] setUser: res];
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil];
//show message to the user
[[[UIAlertView alloc] initWithTitle:#"Logged in"
message:[NSString stringWithFormat:#"Welcome %#",[res objectForKey:#"username"] ]
delegate:nil
cancelButtonTitle:#"Close"
otherButtonTitles: nil] show];
} else {
//error
[UIAlertView error:[json objectForKey:#"error"]];
}
}];
}
#end
If I figure out the fix, I'll add it here but I'm not sure what is causing this problem, any help would be appreciated.

You can use tap gesture to hide keyboard
-(void)viewDidLoad {
[super viewDidLoad];
UITapGestureRecognizer *tapGestureRecognizer =[[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapReceived:)];
[self.view addGestureRecognizer:tapGestureRecognizer];
}
-(void)tapReceived:(UITapGestureRecognizer *)tapGestureRecognizer {
[self.view endEditing:YES];
[yourtextfield resignFirstResponder];
}
