NSString* name;

//@synthesize name;

- (void)viewDidLoad

{

    [super viewDidLoad];

    name =@"123";

	// Do any additional setup after loading the view, typically from a nib.

}



- (void)viewDidUnload

{

    [self setBb:nil];

    [super viewDidUnload];

    [name release]; 

    // Release any retained subviews of the main view.

}



- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);

}



- (IBAction)a:(id)sender {

    name=[name stringByAppendingString: @"abcd"];

}



- (IBAction)b:(id)sender {

    //name=[name stringByAppendingString: @"abcd"];

    NSLog(@"%@",name);

}

打印不出我想要的123abcd来谁知到为什么啊我已经吧name弄成全局的了啊
