Interface jump and pass value

In APPDelegate.h, the entry part of the project

Didfinishlaunchingwithoptions This method means that the app starts and then goes to the custom interface

The following myviewcontroller are custom classes, i.e. an interface implements the Uiviewcontroller interface

-  (BOOL) Application: (uiapplication *) Application didfinishlaunchingwithoptions: (NSDictionary  *) launchoptions {    // override point for customization  after application launch.        self.window =  [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];         self.window.backgroundColor = [UIColor whiteColor];         MyViewController *myController = [[MyViewController  alloc] init];    uinavigationcontroller *navcontroller = [[ uinavigationcontroller alloc] initwithrootviewcontroller:mycontroller];         self.window.rootviewcontroller = navcontroller;    [ Self.window makekeyandvisible]; &nbSp;      return yes;} 

myviewcontroller.h//defines four controls @interface myviewcontroller : uiviewcontroller@property  ( strong, nonatomic)  UILabel *labelNum; @property   (strong, nonatomic)  UILabel  *labelpwd, @property   (strong, nonatomic)  UITextField *fieldNum; @property   (Strong,  nonatomic)  UITextField *fieldPwd; @end  //MyViewController.m-  (void) viewdidload {     [super viewdidload];    // do any additional  setup after loading the view.         self.labelnum = [[uilabel alloc] init];    self.labelnum.frame =  cgrectmake (100, 100, 50, 20);     self.labelnum.text = @ "Num :  ";         self.fieldnum = [[uitextfield alloc]  init];   &nBsp;self.fieldnum.frame = cgrectmake (150, 100, 100, 20);     self.fieldnum.borderstyle = uitextborderstyleroundedrect;         self.labelpwd = [[uilabel alloc] init];    self.labelpwd.frame  = cgrectmake (100, 150, 50, 20);     self.labelpwd.text =  @ "pwd: ";         self.fieldpwd = [[uitextfield  alloc] init];    self.fieldpwd.frame = cgrectmake (150, 150,  100, 20);     self.fieldpwd.borderstyle = uitextborderstyleroundedrect ;         uibutton *btn = [uibutton buttonwithtype: Uibuttontyperoundedrect];    btn.frame = cgrectmake (100, 200, 80,  20);     btn.backgroundcolor = [uicolor graycolor];    [btn settitle:@ "Login"  forstate:uicontrolstatenormal];        //Set Button listener event, monitoring method is login     [btn addtarget:self action: @selector (login)  forcontrolevents: Uicontroleventtouchdown];            [self.view  addSubview:self.labelNum];    [self.view addSubview:self.fieldNum];         [self.view addsubview:self.labelpwd];    [ self.view addsubview:self.fieldpwd];        [self.view  ADDSUBVIEW:BTN];}

Page jumps, and passes parameters

-(void)  login{    nslog (@ "login");         nsstring *num = self.fieldnum.text;    nsstring *pwd =  Self.fieldpwd.text;        if ([num isequaltostring:@ "123"] = = true) {                 NSLog (@ "yes")         //initialize the interface to jump          MainViewController *mm = [[MainViewController alloc] init];                 //Pass the account password to the next interface          [mm initData:num two:pwd];                 //Start Jump          [self.navigationcontroller pushviewcontroller:mm animated:false];    }else{         nslog (@ "error");     }   }

MainViewController.h

@interface mainviewcontroller:uiviewcontroller//@property (nonatomic) nsstring//pass two parameters A, B nsstring type-(void) InitData: (NSString *) A: (NSString *) b; @end

Receive parameters, and save-(void) InitData: (NSString *) A: (NSString *) b{self.num = A;        Self.pwd = b; NSLog (@ "%@,%@", Self.num, self.pwd);}
