如題。。。小白學IPHONE 開發(fā)，

linke了兩個text fild一個button，一個label，想要實現(xiàn)講兩個text field中輸入的字符串合并為一個，點一下button就會顯示在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project來學習，看了document感覺還是不太會,Q
