在第一个界面登陆，在第二个界面显示名字，并且根据不同的名字显示不同的图片 （最好不要加toolbar）
效果图：
单例Number.h:
#import <Foundation/Foundation.h>
@interface Number : NSObject
{
NSString *name;
NSString *password;
}
@property(nonatomic,retain)NSString *name;
@property(nonatomic,retain)NSString *password;
+(Number *)getNumber;
@end
Number.m:
#import "Number.h"
@implementation Number
+(Number *)getNumber
static Number * a;
if (a == Nil) {
a = [Number alloc];
}
return a;
DXWViewController.h:

self.dxwViewController = [[[DXWViewControlleralloc]initWithNibName:@"DXWViewController"bundle:nil]autorelease];
[self.viewinsertSubview:self.dxwViewController.viewatIndex:12];
动态添加ImageView到view中：
UIImage *image = [UIImage imageNamed:@"apple.jpg"];
UIImageView *picView = [[UIImageViewalloc] initWithImage:image];
[self.viewinsertSubview:picView atIndex:13];
picView.frame = CGRectMake(49,62, 200, 160);
