本文主要是介绍实现两个viewController切换，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.声明用于出口和回退的方法
在第一个ViewCon.h 声明
- (IBAction)exitToHere:(UIStoryboardSegue *)sender
在.m文件中实现
- (IBAction)exitToHere:(UIStoryboardSegue *)sender {
// Execute this code upon unwinding.
}
#import "EditorViewController.h"
@interface EditorViewController ()
@property (weak, nonatomic) IBOutlet UITextField *emailField;
- (IBAction)updateEditor:(id)sender;
- (IBAction)hideKeyboard:(id)sender;
@end
@implementation EditorViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.emailField.text=
((ViewController *)self.presentingViewController).emailLabel.text;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)updateEditor:(id)sender {
//把第二视图的textView 传到第一视图的Label
((ViewController *)self.presentingViewController).emailLabel.text=
self.emailField.text;
//[self dismissViewControllerAnimated:YES completion:nil];
}
- (IBAction)hideKeyboard:(id)sender {
//让 emailField退出第一响应者状态，从而隐藏键盘
[self.emailField resignFirstResponder];
}
@end
