我有两种看法。
在第一个视图中，我有 3 个选取器视图，我将选择选取器视图值。
我必须在下一个视图（第二个视图）中显示这些值。
我必须在第二个视图中显示以前选择的数据。

注意 - 我正在使用数组作为 pickerview 数据。

第一个视图（inputViewController.h）

#import <UIKit/UIKit.h>
#import "dataViewController.h" @class dataViewController;


@interface inputViewController : UIViewController<UIScrollViewDelegate,UITextFieldDelegate>{
    NSString *name;
    IBOutlet UIPickerView *agePicker;
    IBOutlet UIPickerView *genderPicker;
    IBOutlet UIPickerView *locationPicker;
    IBOutlet UIScrollView *scroll;
    NSMutableArray *ageArray;
    NSMutableArray *genderArray;
    NSMutableArray *locationArray; }
-(IBAction)saveData:(id)sender; @property(strong,nonatomic) dataViewController *selectData; @property(strong,nonatomic) NSString
*name;

@property(strong, nonatomic) IBOutlet UITextView *nameField; //@property(strong, nonatomic) IBOutlet UIPickerView *agePicker; //@property(strong, nonatomic) IBOutlet UIPickerView *sexpicker;
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; @end

第一个视图（inputViewController.m）

#import "inputViewController.h"
#import "dataViewController.h"

@interface inputViewController ()

@end

@implementation inputViewController @synthesize nameField; @synthesize selectData; @synthesize name; //@synthesize agePicker; //@synthesize sexpicker;

    else {
        return [locationArray objectAtIndex:row];
    }

} 
-(IBAction)saveData:(id)sender{

}

第二个视图（dataViewController.h）

#import <UIKit/UIKit.h>

@interface dataViewController : UIViewController{
    NSString *name;
     } @property(strong,nonatomic) IBOutlet UILabel *nameLabel; @property(strong,nonatomic) IBOutlet UILabel *ageLabel; @property(strong,nonatomic) IBOutlet UILabel *genderLabel; @property(strong,nonatomic) IBOutlet UILabel *locationLabel; @property(nonatomic, retain) NSString *name;


     @end

第二个视图（dataViewController.m）

#import "dataViewController.h"

@interface dataViewController ()

@end

@implementation dataViewController @synthesize nameLabel,ageLabel,genderLabel,locationLabel,name;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self; }

- (void)viewDidLoad {

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated]; }


- (void)viewDidUnload {

尝试这个，

-(IBAction)saveData:(id)sender
{
 selectData=[[dataViewController alloc]initWithNibName:@"dataViewController" bundle:[NSBundle mainBundle]];   //  [selectData setName:self.name];
selectData.strName = nameField.text;
selectData.strAge=[ageArray objectAtIndex:[agePicker selectedRowInComponent:0]];
selectData.strGender=[genderArray objectAtIndex:[genderPicker selectedRowInComponent:0]];
selectData.strLocation=[locationArray objectAtIndex:[locationPicker selectedRowInComponent:0]];
[self.navigationController pushViewController:selectData animated:YES];

}

第二个视图（dataViewController.h）

 #import <UIKit/UIKit.h>

@interface dataViewController : UIViewController
{
NSString *strName;
NSString *strAge;
NSString *strGender;
NSString *strLocation;
IBOutlet UILabel *nameLabel;
IBOutlet UILabel *ageLabel;
IBOutlet UILabel *genderLabel;
IBOutlet UILabel *locationLabel;
} 
@property(nonatomic, retain) NSString *strName;
@property(nonatomic, retain) NSString *strAge;
@property(nonatomic, retain) NSString *strGender;
@property(nonatomic, retain) NSString *strLocation;
@end

第二个视图（dataViewController.m）

#import "dataViewController.h"

@interface dataViewController ()

@end

@implementation dataViewController
@synthesize strName,strAge,strLocation,strGender;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self; }

- (void)viewDidLoad {
  [nameLabel setText:strName];
  [ageLabel setText:strAge];
  [genderLabel setText:strGender];
  [locationLabel setText:strLocation];

[super viewDidLoad];
// Do any additional setup after loading the view from its nib. }
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated]; }


- (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil; }

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait); }
