我有一个Login视图控制器，我想获取用户名和地址以及联系号码，并将其发布在另一个视图控制器上。我可以使用一些有关尝试的建议。

您可以在委托文件中创建一个具有用户登录凭据的登录对象：

#import "Login.h"  

@interface YourAppDelegate : UIResponder{

Login *appLogin;

}

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

然后你的Login.h文件看起来像这样：

@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;

实现（Login.m）文件如下所示：

@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;   
}

使用dealloc方法释放您的属性最后在您的登录视图中，您可以像这样分配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，您希望显示此凭据执行以下操作：

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