How to get more than one Array in a picker view - objective-c

Question

Im really close on this one...For the purposes of this i have two text boxes. when pressed they invoke a ui picker.
text box one returns values 1,2,3,4
text box two returns values A, B, C, D
The problem is that when the picker is presented for text box two it shows the values from text box one, although will select the appropriate row from text box two. Could someone check over my code and tell me where im making an error, thanks.
.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate,UITextFieldDelegate>
{
//decalre picker
UIPickerView *select;
//declare NSArrray
NSArray *arrStatus;
NSArray *arrStatus2;
}
#property (strong, nonatomic) IBOutlet UITextField *text1;
- (IBAction)Value:(id)sender;
#property (strong, nonatomic) IBOutlet UITextField *text2;
#end
.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize text2;
#synthesize text1;
- (void)viewDidLoad
{
select = [[UIPickerView alloc] initWithFrame:CGRectZero];
select.delegate = self;
select.dataSource = self;
[select setShowsSelectionIndicator:YES];
text1.inputView = select;
text2.inputView = select;
arrStatus = [[NSArray alloc] initWithObjects:#"1",#"2",#"3",#"4",nil];
arrStatus2 = [[NSArray alloc] initWithObjects:#"A",#"B",#"C",#"D",nil];
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
//One column
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
//set number of rows
return arrStatus.count;
return arrStatus2.count;
}
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
//set item per row
return [arrStatus objectAtIndex:row];
return [arrStatus2 objectAtIndex:row];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[self setText1:nil];
[self setText2:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
- (IBAction)Value:(id)sender {
NSInteger selectedRow = [select selectedRowInComponent:0];
if([text1 isFirstResponder])
text1.text = [arrStatus objectAtIndex: selectedRow];
[text1 resignFirstResponder];
if ([text2 isFirstResponder])
text2.text = [arrStatus2 objectAtIndex: selectedRow];
[text2 resignFirstResponder];
}
#end
So to sum up im trying to get, 1 picker view, with 1 colum, 2 arrays, 2 text boxes. Ive tried creating another picker view and that didnt work either

Answer 1

The return statement exits the method. Therefore , if you have 2 return statements , it will never get to the second one. You should modify these methods as such:
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
if([text1 isFirstResponder])
return arrStatus.count;
else
return arrStatus2.count;
}
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
if([text1 isFirstResponder])
return [arrStatus objectAtIndex:row];
else
return [arrStatus2 objectAtIndex:row];
}
Hope this helps. Cheers!

Answer 2

This is Code Which is able to show picker view with the given array and textfield will have the first data of the UIPickerView.Please let me know if you have any issue.I did it for one textfield for next textfield you just need to figure out using tag of textfield and set the Text.
-(void)viewDidLoad
{
[super viewDidLoad];
arrayNo = [[NSArray alloc] initWithObjects:#"1",#"2",#"3",#"4",nil];
[pickerView selectRow:1 inComponent:0 animated:NO];
self.text1.text= [arrayNo objectAtIndex:[pickerView selectedRowInComponent:0]];
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
return 1;
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
mlabel.text= [arrayNo objectAtIndex:row];
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
{
return [arrayNo count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;
{
return [arrayNo objectAtIndex:row];
}
