การต่อ String ใช้ไหมครับ อ่านคำถามแล้ว งง นิดหน่อยถ้าต่อ String ใช้ตามนี้ครับ
![iOS iOS](https://www.thaicreate.com/upload/stock/20140301193329.png?v=1001)
Code (Objective-C)
-(IBAction)buta:(id)sender
{
NSString *a = txt1.text;
NSString *b = txt2.text;
NSString *c;
c = [NSString stringWithFormat:@"%@ %@",a,b];
lblshow.text = c;
}
ใช้ stringWithFormat เอาไว้ใช้งานต่อ string ครับ ลองเอาไปยุคกับที่ถามมาดูครับผม
