改變鍵盤顏色 iphone

1.只有這2種數字鍵台才有效果。UIKeyboardTypeNumberPad，UIKeyboardTypePhonePad
2. 。keyboardAppearance ＝ UIKeyboardAppearanceAlert

複製代碼 - (void)textViewDidBeginEditing:(UITextView *)textView{     NSArray *ws = [[UIApplication sharedApplication] windows];     for(UIView *w in ws){         NSArray *vs = [w subviews];         for(UIView *v in vs){             if([[NSString stringWithUTF8String:object_getClassName(v)] isEqualToString:@"UIKeyboard"]){                 v.backgroundColor = [UIColor redColor];             }         }     } }
