I'm developing an iphone app.

When my app running (during test on my computer), i need to change the value in a textfield box but when it s done, the keyboard stays, and i can't get back to the app, i'm trapped !

How could i close the keyboard and go on ?

Many thanks

Set the delegate to UITextField, then implement UITextField delegate methods this will enable the user to use the Keyboards Return Key to hide the keyboard. 

-(BOOL) textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];
    return YES;
}

If you are using a UIButton then

- (IBAction)hideKeyboard {
    [self.view endEditing:YES];
}

If you want to resign the keyboard when the user touch the screen outside the UITextField then use the following code which will work on all the UITextField in the UIView

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UIView * txt in self.view.subviews){
        if ([txt isKindOfClass:[UITextField class]] && [txt isFirstResponder]) {
            [txt resignFirstResponder];
        }
    }
}

OR 

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.view endEditing:YES];    
}
