如果检查了两个值，则NSString应该是..

Question

我已经在iOS应用程序中创建了复选框。我正在尝试编写说："如果选中了框8并检查了框9，self.skillset ="一句和句子二"。我将如何处理？/p>

如果检查了Box 8，则比Self.Skillset =句子一=一个 - 如果检查了Box 9，则Self.SkillSet =句子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;
    }
}

Answer 1

不确定您在问什么，但这是？

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

Answer 2

从这种方式中，您也可以实现

if (checked9 && checked8) {
     self.skillSet = [self.skillSet stringByAppendingString:@" "];
     self.skillSet = [self.skillSet stringByAppendingString:@"and sentence Two"];
}
