uitextfield

I am trying to move a text box from the bottom of the screen in an iPad app so that the keyboard does not cover it. I have the following which works. -(void) textViewDidBeginEditing:(UITextView *) observationComment { observationComment.frame=CGRectMake(190, 100, 700, 250); } But 1 - I would like to animate the movement - is this possible? 2 - I get a warning Local declaration of 'observationComment' hides instance variable Any advice? Maybe this is not the best way to do it. John Sauer I previously found the answer here , but I had to add code so that the View Controller's view.frame adjusts

I have a UITableViewController with prototype cells containing UITextFields. To configure these custome cells, I've created a UITableViewCell subclass. I've conected the textField to the cell subclass via an outlet (nonatomic, weak) . On this subclass I've created a protocol for which the UITableViewController is its delegate so that everytime something changes in these textFields, the TableViewController knows about it. Basically I wanted this to save the values on the NSUserDefaults Besides, in order to dynamically obtain values from these textFields, I can do something like this: (

Here are my codes: - (void)viewDidLoad { [super viewDidLoad]; // passwordTextField cannot get focus after click next key due to this RAC RAC(self.loginButton, enabled) = [RACSignal combineLatest:@[self.userTextField.rac_textSignal, self.passwordTextField.rac_textSignal] reduce:^id (NSString *user, NSString *password) { if ([user length] > 0 && [password length] > 0) { return @YES; } return @NO; }]; } - (BOOL)textFieldShouldReturn:(UITextField *)textField { if (textField == self.userTextField) { [self.passwordTextField becomeFirstResponder]; } else { [self loginAction:textField]; } //

I have a question regarding the code found in the Apple documentation Moving content located under the keyboard . I have researched this, but I'm looking for clarification on the concepts I am fuzzy on here before I start getting fancy with alternate solutions. Unfortunately, as soon as the keyboard animation finishes moving the keyboard up, the view moves down and completely out of site. This happens whether the text field is actually the one that gets covered by the keyboard or not. So now I'm back to trying to understand the code provided in the documentation and after attempts changing a

I know that if you use the following line of code, you can detect what the user has typed in a TEXT VIEW. if ([[textView text] isEqualToString:@"") I want to detect whether the user has typed anything in a text FIELD, and this does not work with text fields. What should I change? Thanks for your help! The UITextFieldDelegate is the preferred way to find this out. - (void)textFieldDidBeginEditing:(UITextField *)textField - this will only tell you that it has become the first responder / key field, this does not guarantee that the user modified the value - (BOOL)textField:(UITextField *

A customer of my app sent me this strange crash report and I cannot figure out how this could ever crash. I cannot reproduce the problem myself, so am reliant on the crash report. It crashes on the following very simple line of code: UITextField *value = [[UITextField alloc] initWithFrame:frame]; The crash seems to be related to key-value-observing (KVO), but I am not doing anything with that here; it's a simply constructor! The only possibility I could see, is that another thread is writing to a dealloc'ed object that happens to have the same memory address as an object that is created by the

Is that possible to remove the dots which are displayed next to uitextfield when text is larger than the width of the uitextfield. There is a property lineBreakMode which defines the behaviour when the text to be displayed is larger than the box of the control //UILineBreakMode //Options for wrapping and truncating text. typedef enum { UILineBreakModeWordWrap = 0, UILineBreakModeCharacterWrap, UILineBreakModeClip, UILineBreakModeHeadTruncation, UILineBreakModeTailTruncation, UILineBreakModeMiddleTruncation, } UILineBreakMode; If you do not want any dots you can use UILineBreakModeClip which
