objective-c - 想做一個可以講textfield的內容合併成一個字串的功能

Question

如題。。。小白學IPHONE 開發，

linke了兩個text fild一個button，一個label，想要實現講兩個text field中輸入的字符串合並為一個，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

Answer 1

NSString *combinedWord= [firstText.text stringByAppendingString:secondText.text];

或

NSString *combinedWord= [NSString stringWithFormat:@"%@%@",firstText.text,secondText.text];

Answer 2

- (IBAction)myButtonPressed:(id)sender {
    self.combinedWord.text = [self.secondText.text stringByAppendingString:self.firstText.text];
}

stringByAppendingString用來拼接一個字串

Answer 3

stringWithFormat
