使用UIGlassButton我想在我的iPhone應用程序使用UIGlassButton,我在我的視圖控制器下面的代碼:不能在iOS4的

UIGlassButton *myButton = [[UIGlassButton alloc] initWithFrame:CGRectMake(2,2,316,50)]; 
[myButton addTarget:self action:@selector(myFunction:) forControlEvents:UIControlEventTouchDown]; 
[myButton setTitle:@"Neat button!" forState:UIControlStateNormal]; 
[myButton setTintColor:[UIColor colorWithWhite:0.20f alpha:1]]; 
[self.view addSubview:myButton]; 

我增加了指令@class UIGlassButton;在視圖控制器的頭文件中,但我結束了以下錯誤:

Undefined symbols for architecture i386: 
    "_OBJC_CLASS_$_UIGlassButton", referenced from: 
    objc-class-ref in ControlViewController.o 
ld: symbol(s) not found for architecture i386 
collect2: ld returned 1 exit status

UIGlassButton不是Apple組件。它可能屬於另一個需要導入的自定義庫。
