Picker to NSString to UITextField - ios

Question

I have this:
AddSightingViewController.h
#import <UIKit/UIKit.h>
#class MovieSighting;
#interface AddSightingViewController : UIViewController <UITextFieldDelegate, UIPickerViewDelegate, UIPickerViewDataSource>
#property (weak, nonatomic) IBOutlet UITextField *movieTitleInput;
#property (weak, nonatomic) IBOutlet UITextField *directorInput;
#property (weak, nonatomic) IBOutlet UITextField *estrenoInput;
#property (strong, nonatomic) MovieSighting *movieSighting;
#end
and this:
AddSightingViewController.m
#import "AddSightingViewController.h"
#import "MovieSighting.h"
#interface AddSightingViewController ()
#property (strong, nonatomic) NSArray *array;
#property (strong, nonatomic) UITextField *genero;
#end
#implementation AddSightingViewController
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
if ((textField == self.movieTitleInput) || (textField == self.estrenoInput) || (textField == self.directorInput)) {
[textField resignFirstResponder];
}
return YES;
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSArray *generos = [[NSArray alloc] initWithObjects:#"Drama",#"Fantástico",#"Aventuras",#"Policíaco",#"Romántica",#"Comedia",#"Documental",#"Terror", nil];
self.array = generos;
}
#pragma mark Picker Data Source Methods
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
return [_array count];
}
#pragma mark Picker Delegate Methods
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
return [_array objectAtIndex:row];
}
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
NSString *generoInput = [self.array objectAtIndex:row];
}
//
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ReturnInput"]) {
if ([self.movieTitleInput.text length] || [self.directorInput.text length]|| [self.estrenoInput.text length] )
{
MovieSighting *sighting;
NSUInteger *valor = (NSUInteger *)[[self.estrenoInput text] integerValue];
sighting = [[MovieSighting alloc] initWithName:self.movieTitleInput.text anyo:valor genero: director:self.directorInput.text];
self.movieSighting = sighting;
}
}
}
#end
How can I use:
NSString *generoInput = [self.array objectAtIndex:row];
To transform to a property UITextField that I created:
#property (strong, nonatomic) UITextField *genero;
And then use that with the method sighting at the end?
Then I can use it to compare on the method called textFieldShouldReturn.
I´ve been doing that:
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
NSString *generoInput = [self.array objectAtIndex:row];
UITextField *nuevo = (UITextField*)[generoInput capitalizedString];
_genero = nuevo;
}
And prepareForSegue method:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ReturnInput"]) {
if ([self.movieTitleInput.text length] || [self.directorInput.text length]|| [self.estrenoInput.text length]
|| [self.genero.text length])
{
MovieSighting *sighting;
NSUInteger *valor = (NSUInteger *)[[self.estrenoInput text] integerValue];
sighting = [[MovieSighting alloc] initWithName:self.movieTitleInput.text anyo:valor genero:self.genero.text director:self.directorInput.text];
self.movieSighting = sighting;
}
}
}
But don´t work the app... Any idea?
When I add other movie and clic on Add:
Appeared that:
Error code:
2013-12-19 21:43:19.875 MovieWatching[920:70b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<AddSightingViewController 0x8a63190> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key staticDataSource.'

Answer 1

You want:
self.genero.text = [generoInput capitalizedString];
