以及如何解决“预期的';' 在'{'令牌之前？下面的代码（来自xcode 3.2.3）

- (void)viewDidUnload {

    self.cheatName = nil;

    self.description = nil;

}

两个错误都在第一行

- (void)viewDidLoad {
    [super viewDidLoad];

    [self.titleLabel setText:self.title];
    [self.descriptionLabel setText:self.description];


    float textHeight = [MLUtils calculateHeightOfTextFromWidth:self.description : descriptionLabel.font :descriptionLabel.frame.size.width :UILineBreakModeWordWrap];

    CGRect frame = descriptionLabel.frame;
    frame.size.height = textHeight;
    descriptionLabel.frame = frame;

    CGSize contentSize = descriptionScrollView.contentSize;
    contentSize.height = textHeight;
    descriptionScrollView.contentSize = contentSize;



- (void)viewDidUnload {
    self.cheatName = nil;
    self.description = nil;

}

您缺少右括号：

- (void)viewDidLoad {
    [super viewDidLoad];

    [self.titleLabel setText:self.title];
    [self.descriptionLabel setText:self.description];


    float textHeight = [MLUtils calculateHeightOfTextFromWidth:self.description : descriptionLabel.font :descriptionLabel.frame.size.width :UILineBreakModeWordWrap];

    CGRect frame = descriptionLabel.frame;
    frame.size.height = textHeight;
    descriptionLabel.frame = frame;

    CGSize contentSize = descriptionScrollView.contentSize;
    contentSize.height = textHeight;
    descriptionScrollView.contentSize = contentSize;

} // <-- HERE

- (void)viewDidUnload {
    self.cheatName = nil;
    self.description = nil;

}

其次，我不确定这条线是否有效：

float textHeight = [MLUtils calculateHeightOfTextFromWidth:self.description : descriptionLabel.font :descriptionLabel.frame.size.width :UILineBreakModeWordWrap];

我认为您必须添加参数名称，例如（虚构名称！）：

float textHeight = [MLUtils calculateHeightOfTextFromWidth:self.description font: descriptionLabel.font width:descriptionLabel.frame.size.width whatever:UILineBreakModeWordWrap];

通常这意味着您在那条线上方的某个地方有错误。或者放错了{}。
