Question

我希望你能帮助我。

我需要一个变量，当我点击View1上的任何按钮（View 1有6个按钮）时，变量应该有任何值，例如1-6。然后在视图二中，我将检查变量的值。

你的view2.h类看起来应该是这样的

#import <UIKit/UIKit.h>

@interface ForgotPasswordViewController : UIViewController

@property (nonatomic, retain) NSString *strName;

@end

你的view2.m类看起来应该是这样的

#import "ForgotPasswordViewController.h"

@interface ForgotPasswordViewController ()

@end

@implementation ForgotPasswordViewController

@synthesize strName;

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

#pragma mark -
#pragma mark - View LifeCycle
-(void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    NSLog(@"the value of name is %@",strName);
}

#pragma mark -
#pragma mark - Memory Mgmt
-(void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

你的view1.m类中的

应该是

#import "ViewController.h"
#import "ForgotPasswordViewController.h"

@interface ViewController ()

@end

@implementation ViewController

#pragma mark -
#pragma mark - View LifeCycle
-(void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

    ForgotPasswordViewController *vcForgotPasswordViewController = [[ForgotPasswordViewController alloc] initWithNibName:@"ForgotPasswordViewController" bundle:nil];
    vcForgotPasswordViewController.strName = @"Dhaval";
    [self.navigationController pushViewController:vcForgotPasswordViewController animated:YES];
}

#pragma mark -
#pragma mark - Memory Mgmt
-(void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

希望你能得到它，你可以向我寻求任何帮助，谢谢：）
