最简单的属性传值

1、先建立两个 FirstViewController、SecondViewController 视图

2、FirstViewController

        (1).h里面不作改变

        (2).m里面添加一个头文件  #import "SecondViewController.h"

                //添加一个按钮

                    //跳转

                    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

                    [btnsetTitle:@"跳入第二个界面" forState:UIControlStateNormal];

                    [btnsetBackgroundColor:[UIColor blackColor]];

                    btn.frame = CGRectMake((self.view.bounds.size.width-200)/2, 200, 200, 50);

                    [self.view addSubview:btn];

                    [btnaddTarget:self action:@selector(secondView)    

                     forControlEvents:UIControlEventTouchUpInside];//添加事件

                   -(void)secondView{

                    //    事件函数

                        SecondViewController *secondVC  =  [[SecondViewController alloc] init];

                        secondVC.gain = @“我拿到值了！”;//赋值

                        secondVC.hidesBottomBarWhenPushed = YES;//隐藏底部导航栏

                        [self.navigationController   pushViewController:secondVC   animated:YES];

                    }

2、SecondViewController界面

    (1) .h

                @property (nonatomic, strong) NSString *gain;//取值

    (2).m  

                NSLog(@"我拿到的值 = %@",self.gain);//查看是有将值传入

以上是我个人简单的传值方法

若有问题，请帮忙指出，谢谢观看！
