如何在Objective-C中连接字符串?
首先,平台是iPhone,label.text更改显示的标签。考虑这种情况:

我有一个整数数组。我想在屏幕上显示它。
I've an array of integers. And I want to display it on the screen.

-(IBAction) updateText: (id)sender {
int a[2];
a[0]=1;
a[1]=2;
a[2]=3;

label.text = [NSString stringByAppendingString: [NSString stringWithFormat: @"%i", a[i]]];
}
