Login 如何传递用户'；将信息从登录视图发送到另一个视图控制器

我有一个登录视图控制器，我想获得用户名、地址和联系电话，并将其发布到另一个视图控制器上。我可以使用一些建议来尝试什么。

您可以在代理文件中创建一个登录对象，该对象将具有用户的登录凭据，如下所示：

#import "Login.h"  

@interface YourAppDelegate : UIResponder{

Login *appLogin;

}

@property(nonatomic,retain) Login *appLogin; // Don't forget to release it in the dealloc method

@interface Login : NSObject <NSCoding> {

NSString *userName; 
NSString *address;
NSString *contactNumber;

// You can add more properties
}

@property (nonatomic, retain)NSString *userName;
@property (nonatomic, retain)NSString *address;
@property (nonatomic, retain)NSString *contactNumber;

- (id)initWithUserName:(NSString *)name andAddress:(NSString *)addr andContactNumber:(NSString *)cNumber;

@implementation Login

@synthesize userName;
@synthesize address;
@synthesize contactNumber;

- (id)initWithUserName:(NSString *)name andAddress:(NSString *)addr andContactNumber:(NSString *)cNumber{

if(self = [super init]){

     [self setUserName:name];
     [self setAddress:addr];
     [self setContactNumber:cNumber];
}

return self;   
}

YourAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
NSString *userName = [delegate.appLogin userName];

然后，您的Login.h文件将如下所示：

#import "Login.h"  

@interface YourAppDelegate : UIResponder{

Login *appLogin;

}

@property(nonatomic,retain) Login *appLogin; // Don't forget to release it in the dealloc method

@interface Login : NSObject <NSCoding> {

NSString *userName; 
NSString *address;
NSString *contactNumber;

// You can add more properties
}

@property (nonatomic, retain)NSString *userName;
@property (nonatomic, retain)NSString *address;
@property (nonatomic, retain)NSString *contactNumber;

- (id)initWithUserName:(NSString *)name andAddress:(NSString *)addr andContactNumber:(NSString *)cNumber;

@implementation Login

@synthesize userName;
@synthesize address;
@synthesize contactNumber;

- (id)initWithUserName:(NSString *)name andAddress:(NSString *)addr andContactNumber:(NSString *)cNumber{

if(self = [super init]){

     [self setUserName:name];
     [self setAddress:addr];
     [self setContactNumber:cNumber];
}

return self;   
}

YourAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
NSString *userName = [delegate.appLogin userName];

使用dealloc方法释放您的属性 最后，在登录视图中，您可以按如下方式分配appDelegate登录对象：

YourAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
Login *lObject = [[Login alloc] initWithUserName:@"user name here" andAddress:@"Address here" andContatNumber@"Contact number here"];

[delegate setAppLogin:lObject];
[lObject release];

然后在视图控制器中，您希望显示此凭据，请执行以下操作：

#import "Login.h"  

@interface YourAppDelegate : UIResponder{

Login *appLogin;

}

@property(nonatomic,retain) Login *appLogin; // Don't forget to release it in the dealloc method

@interface Login : NSObject <NSCoding> {

NSString *userName; 
NSString *address;
NSString *contactNumber;

// You can add more properties
}

@property (nonatomic, retain)NSString *userName;
@property (nonatomic, retain)NSString *address;
@property (nonatomic, retain)NSString *contactNumber;

- (id)initWithUserName:(NSString *)name andAddress:(NSString *)addr andContactNumber:(NSString *)cNumber;

@implementation Login

@synthesize userName;
@synthesize address;
@synthesize contactNumber;

- (id)initWithUserName:(NSString *)name andAddress:(NSString *)addr andContactNumber:(NSString *)cNumber{

if(self = [super init]){

     [self setUserName:name];
     [self setAddress:addr];
     [self setContactNumber:cNumber];
}

return self;   
}

YourAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
NSString *userName = [delegate.appLogin userName];

将此作为起点进行检查。嗨，ACB谢谢你的回复，我会查一下：）我已经看过了。。但是我仍然没有找到答案：（那些教程似乎只使用像facebook这样的联合登录，或者只包含名称和密码的登录，所以我可以理解你的观点。是的，德兰布林你是对的，所以我仍然在寻找帮助，我如何开始……：（“未知类型名称‘登录’”-我在“登录*应用登录”中得到这个错误我的loginviewcontroller.h中的声明感谢您的回复先生：）…请耐心等待我：（您必须在loginviewcontroller.h文件的开头导入Login.h文件：#import Login.hNO visible@interface for'Login'声明选择器'initWithUserName:（NSString*）名称和地址：（NSString*）addr和contactnumber:（NSString*））cNumber“…这是这一行-->Login*lObject=[[Login alloc]initWithUserName:@“此处用户名”和Address:@“此处地址”和contatnumber@“此处联系电话”]；这意味着什么？发布在ios6中被取消权限。
