如題。。。小白學(xué)IPHONE 開(kāi)發(fā)，

linke了兩個(gè)text fild一個(gè)button，一個(gè)label，想要實(shí)現(xiàn)講兩個(gè)text field中輸入的字符串合並為一個(gè)，點(diǎn)一下button就會(huì)顯示在lable中

附上代碼：

@interface HWViewController ()
@property (strong, nonatomic) IBOutlet UILabel *combinedWord;
@property (strong, nonatomic) IBOutlet UITextField *secondText;
@property (strong, nonatomic) IBOutlet UITextField *firstText;
@property (strong, nonatomic) IBOutlet UIButton *combineButton;


- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.combinedWord.text=@"Wating...";

}
- (IBAction)myButtonPressed:(id)sender {
    NSString *combinedWord= textfiled1+textfield2

求高手回答，想自己做一個(gè)project來(lái)學(xué)習(xí)，看了document感覺(jué)還是不太會(huì),Q
