How I can get the value of my UITextField? - objective-c

Question

how I can get the value of my UITextField ? When I declare my UITextField in the Storyboard, I know but like this, I don't know.
(sorry for my English, I'm French)
Thank you in advance for your answer.
//Ajout d'un Text Field
CGRect rectTF = CGRectMake(10,70,100,20); // Définition d'un rectangle
UITextField *articleSaisi = [[UITextField alloc] initWithFrame:rectTF];
articleSaisi.borderStyle = UITextBorderStyleLine;
articleSaisi.placeholder = #"Article";
[self.view addSubview: articleSaisi];

Answer 1

I am not quite sure whether you want to access the value or you want to associate your UI element to your code:
Try this if you are saying that you want to access the text value.
atricleSaisi.text
Try to control drag the UI element to either your corresponding .h or .m file so that it can create IBOutlet for you if you are saying that you want to connect your UI element to your code.
Highly recommend you go check the documentation.

Answer 2

if you want to know when the user pressed return, as per your comment, then you should create a UITextViewDelegate for your text view and define its textFieldShouldReturn method:
Discussion
The text field calls this method whenever the user taps the return button. You can use this method to implement any custom behavior when the button is tapped.
Also, give a look at textFieldDidEndEditing, which is called whenever there is a focus change and you should define to correctly handle user input.
Old answer:
If I do not understand you incorrectly, you want to create a UITextField programmatically (i.e., not through a Storyboard).
In this case, you should put you initialisation code inside the viewDidLoad method of your view controller and make sure that you define a property for the text field instead of a local variable:
#interface MyViewController : UIViewController
....
#property (nonatomic, strong) UITextField* articleSaisi;
...
#end
- (void)viewDidLoad {
CGRect rectTF = CGRectMake(10,70,100,20); // Définition d'un rectangle
self.articleSaisi = [[UITextField alloc] initWithFrame:rectTF];
self.articleSaisi.borderStyle = UITextBorderStyleLine;
self.articleSaisi.placeholder = #"Article";
[self.view addSubview:self.articleSaisi];
}
If you do so, you can access the text field value from any other method in the view controller through its text property:
self.articleSaisi.text
