ios - 如果检查两个值，NSString 应该是...？

Question

我在我的 iOS 应用程序中创建了复选框。我正在尝试编写这样的代码:“如果框 8 被选中并且框 9 被选中，self.skillSet =“第一句和第二句”。我该怎么做呢？目前，我的代码如下:

If box 8 is checked, than self.skillSet = Sentence one - if box 9 is checked, self.skillSet = sentence two.

ViewController.m

- (IBAction)oralCheck:(id)sender {

    if (!checked8) {
        [self.oralValue setImage:[UIImage imageNamed:@"checkedwhite.png"] forState:UIControlStateNormal];
        checked8 = YES;

        self.skillSet = @"Sentence One";
        NSLog(@"%@", self.skillSet);
    }
    else if (checked8) {
        [self.oralValue setImage:[UIImage imageNamed:@"uncheckedwhite.png"] forState:UIControlStateNormal];
        checked8 = NO;
    }
}

- (IBAction)injectedCheck:(id)sender {

    if (!checked9) {
        [self.injectValue setImage:[UIImage imageNamed:@"checkedwhite.png"] forState:UIControlStateNormal];
        checked9 = YES;

        self.skillSet = @"Sentence Two";
        NSLog(@"%@", self.skillSet);
    }
    else if (checked9) {
        [self.injectValue setImage:[UIImage imageNamed:@"uncheckedwhite.png"] forState:UIControlStateNormal];
        checked9 = NO;
    }
}

不确定你在问什么，但这是吗？

if checked9 && checked8 {
    self.skillSet = "Sentence one and sentence two"
}
