I am new in IOS. When I'm clicking on the following Login Button:
I'm using this code to generate a popup:
- (UIView *)createLoginView
{
UIView *alertView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 130)];
UITextField *email = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 280, 50)];
email.tag=420;
email.layer.cornerRadius = 5;
[email setTag:99];
[email setTextAlignment:NSTextAlignmentCenter];
[email setKeyboardType:UIKeyboardTypeEmailAddress];
[email setPlaceholder:#"Email"];
[email setBackgroundColor:[UIColor colorWithRed:243/255.0 green:243/255.0 blue:243/255.0 alpha:1.0]];
[email setReturnKeyType:UIReturnKeyNext];
[email setAutocorrectionType:UITextAutocorrectionTypeNo];
UITextField *pass = [[UITextField alloc] initWithFrame:CGRectMake(10, 70, 280, 50)];
pass.layer.cornerRadius = 5;
[pass setTag:100];
[pass setTextAlignment:NSTextAlignmentCenter];
[pass setSecureTextEntry:YES];
[pass setPlaceholder:#"Password"];
[pass setBackgroundColor:[UIColor colorWithRed:243/255.0 green:243/255.0 blue:243/255.0 alpha:1.0]];
[pass setReturnKeyType:UIReturnKeyGo];
[alertView addSubview:email];
[alertView addSubview:pass];
return alertView;
}
The login popup is working properly but when I click on the 'Forget?' button of the popup, the forgot password popup does not show up. Here is the code for forget password popup.
- (UIView *)createForgotPasswordView
{
UIView *alertView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 130)];
UITextField *email = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 280, 50)];
email.layer.cornerRadius = 5;
[email setTag:22];
[email setTextAlignment:NSTextAlignmentCenter];
[email setKeyboardType:UIKeyboardTypeEmailAddress];

[email setReturnKeyType:UIReturnKeyNext];
[email setAutocorrectionType:UITextAutocorrectionTypeNo];
[alertView addSubview:email];
return alertView;
}
And I'm using it like :
- (IBAction)LogInClick:(UIButton *)sender {
IOS7AlertView *applyMsg = [[IOS7AlertView alloc] init];
[applyMsg setContainerView:[self createLoginView]];
[applyMsg setButtonTitles:[NSMutableArray arrayWithObjects:#"Forgot?", #"Login", nil]];
[applyMsg setOnButtonTouchUpInside:^(IOS7AlertView *alertView, int buttonIndex) {
if(buttonIndex==0)
{
[alertView close];
NSLog(#"Forgot Section");
IOS7AlertView *applyPop = [[IOS7AlertView alloc] init];
[applyPop setParentView:[self createForgotPasswordView]];
[applyPop setButtonTitles:[NSMutableArray arrayWithObjects:#"Next", #"Cancel", nil]];
}
}];
But the problem is the next popup does not show up? What is the problem? Please help.
already UIalertview hierarchy has email and password options.
try this and this is native
- (IBAction)LogInClick:(UIButton *)sender {
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Login"
message:nil
delegate:self
cancelButtonTitle:#"Signup"
otherButtonTitles:#"Login",#"Forgot password", nil];
alert.alertViewStyle=UIAlertViewStyleLoginAndPasswordInput;
[[alert textFieldAtIndex:0]setKeyboardType:UIKeyboardTypeEmailAddress];
[[alert textFieldAtIndex:0]setPlaceholder:#"Email address"];
[[alert textFieldAtIndex:1]setPlaceholder:#"Password"];
alert.tag=10;
[alert show];
}
and the alert view delegate method is
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (alertView.tag==65)
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Login"
message:nil
delegate:self

otherButtonTitles:#"Login",#"Forgot password", nil];
alert.alertViewStyle=UIAlertViewStyleLoginAndPasswordInput;
[[alert textFieldAtIndex:0]setKeyboardType:UIKeyboardTypeEmailAddress];
[[alert textFieldAtIndex:0]setPlaceholder:#"Email address"];
[[alert textFieldAtIndex:1]setPlaceholder:#"Password"];
alert.tag=10;
[alert show];
}
if (alertView.tag==10)
{
if (buttonIndex == 0) {
NSLog(#"signup");
//Navigate to Signup page
}
else if (buttonIndex == 2) {
NSLog(#"Forgot password");
// //Navigate to Forgot password page
}
else if (buttonIndex == 1) {
NSLog(#"YES");
NSString *usernameInput=[alertView textFieldAtIndex:0].text;

//pass the email id , password
NSLog(#"1 %#", usernameInput);

// COMMENT: check if input information is valid or not
if([usernameInput isEqualToString:#""])

else
{
//pass teh data to server or login process
}
}
}
I've written a simple app which validates user input (whether NULL or longer than a define length). It should return validation error messages when validation fails and otherwise, redirect to another page.
However, the app only returns the messge for the first condition (Username is Empty) for all scenarions. (Such as username is filled and password is empty, etc.)
m file:
- (IBAction)doLogin {
if(uname.text==NULL) {
UIAlertView *err1 = [[UIAlertView alloc]
initWithTitle:#"Required field!" message:#"Username is empty." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[err1 show];
NSLog(#"%#",uname.text);
}
else if(passw.text==NULL) {
UIAlertView *err2 = [[UIAlertView alloc]
initWithTitle:#"Required field!" message:#"Password is empty." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[err2 show];
NSLog(#"%#",passw.text);
}
else if (uname.text.length < 6)
{
UIAlertView *err3 = [[UIAlertView alloc]
initWithTitle:#"Invalid!" message:#"Enter a username longer than 6 chars." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[err3 show];
NSLog(#"%#",uname.text);
}
else if (uname.text.length < 8)
{
UIAlertView *err4 = [[UIAlertView alloc]
initWithTitle:#"Invalid!" message:#"Enter a password longer than 8 chars." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[err4 show];
NSLog(#"%#",uname.text);
}
else {
/*UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"" message:#"Thank you" delegate:self cancelButtonTitle:#"Close" otherButtonTitles:#"OK", nil];
[alert show];*/
UIViewController* flipViewController = [[UIViewController alloc] initWithNibName:#"flip" bundle:[NSBundle mainBundle]];
[self.view addSubview:flipViewController.view];
}
An alternative to karthika (but using similar structure) this will provide feedback on the entire form in a single message. Perhaps a little more user friendly and certainly reduces negative user interaction.
-(BOOL)isFormDataValid{
NSMutableArray *errorMessages = [[NSMutableArray alloc] init];
if([self.emailTextField.text isEqualToString:#""])
{
[errorMessages addObject:NSLocalizedString(#"Please enter email",nil)];
}
if([self.passwordTextField.text isEqualToString:#""])
{
[errorMessages addObject:NSLocalizedString(#"Please enter password",nil)];
}
if ([errorMessages count]) {
NSString * msgs = [errorMessages componentsJoinedByString:#"\n"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(#"Whoops!",nil) message:msgs delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
return NO;
} else {
return YES;
}
}
-(BOOL)isFormDataValid{
NSString *errorMessage = nil;
UITextField *errorField;
if([nameTextField.text isEqualToString:#""])
{
errorMessage = #"Please enter username";
errorField = nameTextField;
}
else if([[nameTextField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length]==0)
{
errorMessage = #"white spaces not allowed";
errorField = nameTextField;
}
else if([passwordTextField.text isEqualToString:#""])
{
errorMessage = #"Please enter password";
errorField = passwordTextField;
}
else if([[passwordTextField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length]==0)
{
errorMessage = #"white spaces not allowed";
errorField = passwordTextField;
}
if (errorMessage) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Failed!" message:errorMessage delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
[errorField becomeFirstResponder];
return NO;
}else{
return YES;
}
}
Apart from the fact that you do
else if (uname.text.length < 8)
{
UIAlertView *err4 = [[UIAlertView alloc]
initWithTitle:#"Invalid!" message:#"Enter a password longer than 8 chars." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[err4 show];
NSLog(#"%#",uname.text);
}
instead of
else if (passw.text.length < 8)
{
UIAlertView *err4 = [[UIAlertView alloc]
initWithTitle:#"Invalid!" message:#"Enter a password longer than 8 chars." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[err4 show];
NSLog(#"%#",passw.text);
}
Your code should work just fine.
Also, bear in mind that a text field's text won't be nil, it will just be an empty string (lenght == 0), unless you explicitly set it to nil.
this is my second day on learning XCode, so I'm totally newbie here and I have this .m code :

UIView *fieldEmail = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldEmail.leftViewMode = UITextFieldViewModeAlways;
_fieldEmail.leftView = fieldEmail;
UIView *fieldPassword = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldPassword.leftViewMode = UITextFieldViewModeAlways;
_fieldPassword.leftView = fieldPassword;

return [emailTest evaluateWithObject:emailStr];
}

_labelOutput.text = #"Register?";

if ([_fieldEmail.text length] > 0) {
if(![self validateEmail:[_fieldEmail text]]){

}else{

}
}else{
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Login Error"
message:#"Please enter your email"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
}
}
- (IBAction)loginFacebook {
if ([_fieldPassword.text length] > 15) {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Password Error"
message:#"Password must be less than 15 characters."
delegate:nil

message:#"Please enter your email correctly."
delegate:nil

otherButtonTitles:nil];
[message show];
}
#end
as you can see there, the code I used to display alert box is repeated. Is there any way to put this similar code somewhere up there so it can be called just by giving Title and Message as variable :
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Login Error"
message:#"Please enter your email correctly."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
In PHP world, this method named function, but I don't know what's name in Objective-C world. thank you very much.
To reduce your code why dont you create another method to show the AlertBox ?
- (void) alertWithTitle:(NSString *)title andMessage:(NSString *)msg
{
UIAlertView *message = [[UIAlertView alloc] initWithTitle:title
message:msg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
}
Then simply call :
[self alertWithTitle:(YOUR TITLE) andMessage:(YOUR MESSAGE)];
You have written a handful of methods, have you considered just writing another one? E.g.
- (void) showAlertWithTitle:(NSString *)title andMessage:(NSString *)message
{
...
}
and then when you need an alert call this method, e.g.:
[self showAlertWithTitle:#"Login Error" andMessage:#"Please enter your email correctly."];
HTH
I got app, which can send twits.
I do it in this way:
- (IBAction)twitDream:(id)sender
{
if ([TWTweetComposeViewController canSendTweet]) {
TWTweetComposeViewController *tweet =
[[TWTweetComposeViewController alloc] init];
if (dream.image != [UIImage imageNamed:#"blank-photo.png"])
[tweet addImage:dream.image];
NSString *twitMsg = [dreamField.text stringByAppendingString:#" send via Dreamer"];
[tweet setInitialText:twitMsg];
[self presentModalViewController:tweet animated:YES];
} else {
//can't tweet!
}
}
What should i do when [TWTweetComposeViewController canSendTweet] is equal to NO ? And when it is equal to NO ?
That is full solution code:
- (IBAction)twitDream:(id)sender
{
if ([TWTweetComposeViewController canSendTweet]) {
TWTweetComposeViewController *tweet =
[[TWTweetComposeViewController alloc] init];
if (dream.image != [UIImage imageNamed:#"blank-photo.png"]) {[tweet addImage:dream.image];}
NSString *twitMsg = [dreamField.text stringByAppendingString:#" #Dreamer"];
[tweet setInitialText:twitMsg];
[self presentModalViewController:tweet animated:YES];
} else {
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:#"Sorry"
message:#"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
}
I want to show the user how long it took him or her to answer a certain amount of questions (for example 5) as an alert. I believe that I have the correct timer in place although I could be wrong. How would I finish the coding?
- (void)updateCounter:(NSTimer *)theTimer {
static int count = 0;
count += 1;
NSString *s = [[NSString alloc]
initWithFormat:#"%d", count];
self.timer.text = s;
[s release];
}
- (void)generate
{
int a = 1 + arc4random() % 12;
int b = 1 + arc4random() % 12;
int sum = a * b;
label.text = [NSString stringWithFormat: #"%d * %d = ", a, b];
label.tag = sum;
}
- (void)viewDidLoad
{NSLog(#"viewDidLoad");
[super viewDidLoad];
[self generate];
[self.answer becomeFirstResponder];
UIAlertView *alert;
{alert = [[UIAlertView alloc]
initWithTitle:#"Welcome to iCanMultiply!"
message:#"Tap 'Start' to start the game"
delegate: self
cancelButtonTitle:#"Start"
otherButtonTitles: nil];
}
[alert show];
[alert release];
[NSTimer scheduledTimerWithTimeInterval:1.0f
target:self
selector:#selector(updateCounter:)
userInfo:nil
repeats:YES];
}
- (IBAction)submit:(id)sender {
int num = [answer.text intValue];
UIAlertView *alert;
if (num == label.tag)
{
// answer was correct
alert = [[UIAlertView alloc]
initWithTitle:#"Correct"
message:#"Bet you can't do that twice!"
delegate:self
cancelButtonTitle:#"Next Question"
otherButtonTitles: nil];
// use the alert tag to mark that answer was correct
alert.tag = 1;
} else
{
// answer is incorrect
alert = [[UIAlertView alloc]
initWithTitle:#"Wrong!"
message:#"Sorry, try again..."
delegate:self
cancelButtonTitle:#"Try Again"
otherButtonTitles: nil];
}
// show and release the alert
[alert show];
[alert release];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (alertView.tag == 1)
{
[self generate];
answer.text = #"";
}
}
Store that value and then display it in an alert view.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title" message#"It took you %# seconds.",time delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
Let me know if the ,time works. I haven't tested this yet, but it should work.
