Not able to use two UIPickerView in the same Controller - ios

Question

I'm trying to use more than two UIPickerViews together in one ViewController. Each UIPickerView has different data array. I am using interface builder to link the pickers up. What I want is, after button click, my PickerView will show up and user can select the data from it.That selected data will come in the text field. It is working fine for first PickerView but when I click for the second PickerView, the value is coming from first array and I am not able to write condition. Here's all my code:
.h file
#import <UIKit/UIKit.h>
#interface Tabbar2ViewController : UIViewController<UITextViewDelegate,UITextFieldDelegate,UIPickerViewDataSource,UIPickerViewDelegate>{
IBOutlet UIPickerView *genderPickerView;
IBOutlet UIPickerView *pickerViewoption;
IBOutlet UIButton *BrandPickerBtn;
IBOutlet UIButton *genderPickerfBtn;
NSArray *brands;
NSArray *gender;
BOOL isCheckedpickerView;
IBOutlet UILabel *BrandLabelfield;
IBOutlet UILabel *GenderLabelfield;
}
- (IBAction)action:(id)sender;
- (IBAction)genderAction:(id)sender;
#property(nonatomic,retain)NSArray *brands;
#property(nonatomic,retain)NSArray *gender;
#end
.m file
#import "ttViewController.h"
#interface ttViewController ()
#end
#implementation ttViewController
#synthesize countries,size,brands,gender,activity,condition,color;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

Currently you are checking wrong condition in delegate methods, replace following 3 methods in .m file :
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row
forComponent:(NSInteger)component{
NSString *string;
if (pickerView.tag==1) {
[tabView1 addSubview:pickerViewoption];
string=[self.brands objectAtIndex:row];
}
else if (pickerView.tag==2){
[tabView1 addSubview:genderPickerView];
string=[self.gender objectAtIndex:row];
}
else if (pickerView.tag==3){
[tabView1 addSubview:activityPickerView];
string=[self.activity objectAtIndex:row];
}
else {
[tabView1 addSubview:genderPickerView];
string=[self.gender objectAtIndex:row];
}
return string;
}
- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row
inComponent:(NSInteger)component {
if (thePickerView.tag==1){
BrandLabelfield.text=#"";
BrandLabelfield.text=[brands objectAtIndex:row];
BrandLabelfield.textColor=[UIColor whiteColor];
pickerViewoption.hidden=YES;
}
else if (thePickerView.tag==2){
GenderLabelfield.text=#"";
GenderLabelfield.text=[gender objectAtIndex:row];
GenderLabelfield.textColor=[UIColor whiteColor];
}
else if (thePickerView.tag==3){
ActivityLabelfield.text=#"";
ActivityLabelfield.text=[activity objectAtIndex:row];
ActivityLabelfield.textColor=[UIColor whiteColor];
}
}
- (NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component{
if (pickerView.tag==1)
{
return [brands count];
}
else if (pickerView.tag==2)
{
return [gender count];
}
else if (pickerView.tag==3)
{
return [activity count];
}
return 0;
}
