#import "PassSelectDelegate.h"
@interface ApplyController : UIViewController<PassSelectDelegate, UITextFieldDelegate>
在ApplyController.m中实现协议
-(void)passDelegate:(NSDictionary *)value
{
NSLog("value:%@", value);
}
注意：在从第一个ViewController跳转到第二个ViewController的过程中，指定代理是在第一个viewcontroller中实现的
SecondViewController *viewcontroller = [SecondViewController alloc] init];
viewController.delegate = self;
[self.navigationController pushViewController:viewController animated:YES];
第三步，在第二个viewcontroller中调用这个协议
SecondViewcontroller.h
#import "passSelectDelegate.h"
@property(nonatomic,assign) NSObject<PassSelectDelegate> *delegate;
SecondViewcontroller.m
-(void)confirmSelect:(NSDictionary *)selectValue
{
[self.delegate passValue:selectValue];
[self.navigationController popViewControllerAnimated:YES];
}
[本博文是记录传递参数原理，直接不知代码可能不能执行]
