Question

我有以下代码：

 if (product) {

    if ([product.title isStringOfInterest]) {

        scriptName = [[PPLinearLayoutLabelItem alloc] initWithText:@"" font:[PPFonts bold20] maxWidth:[LayoutValues getMaxWidthClipped]];

        [self.topContainerContent addObject:scriptName];

        extraName = [[PPLinearLayoutLabelItem alloc] initWithText:@"" font:[PPFonts regular14] maxWidth:[LayoutValues getMaxWidthClipped]];
        [scriptName setPaddingTop:20];


        [self.topContainerContent addObject:extraName];
        }
      }

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^(void){
    [self loadProductDetails];
    });



-(void) loadProductDetails{
    IHProduct *product = orderDisplayed.product;
    id<ProductDownloadServiceProtocol> productDetailsDownloader = [[ProductDownloadService alloc] initWithClient:[[HttpClient alloc] initWith:APIbackend forEndpoint:EndpointProduct]];


    [productDetailsDownloader downloadProductWithProductID:product.productID success:^(ProductDownloadResponse *response) {

    scriptName.label.text = [NSString stringWithFormat:@"%@ (%@)",response.product.title,response.product.pillTypeShort];
    extraName.label.text =  response.product.sameAs;

    NSString *qtyText = [NSString stringWithFormat:@"%@ PACKS (%@ at $%@ per pack)",[orderDisplayed.interval objectForKey:@"quantity_per_interval"], [orderDisplayed.interval objectForKey:@"quantity_per_interval"], response.product.price];

    quantity.label.text = qtyText;
    } error:^(ProductDownloadResponse *response) {
        [self hideHttpLoadingOverlay];
        [RMUniversalAlert showAlertInViewController:self
                                          withTitle:alertErrorTitle
                                            message:@"Error downloading mail order product details"
                                  cancelButtonTitle:OKDialogButton     
                             destructiveButtonTitle:nil 
                                  otherButtonTitles:nil
                                           tapBlock:nil];
        }];
}

标签extraname和scriptname最终被填满或被砍掉，即不完整的数据。我怎样才能解决这个问题？当我静态地将大文本放入其中时，数据很好地填充到这些视图中。救命啊！

如果您希望根据文本内容调整UILabel的宽度，请使用以下代码;

NSDictionary *fontAttributes = @{NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue" size:14]};
CGRect rectOfText = [textToMeasure boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX)
                                            options:NSStringDrawingUsesLineFragmentOrigin
                                         attributes:fontAttributes
                                            context:nil];
CGRect tempFrame = self.label.frame;
tempFrame.size.width = rectOfText.size.width;
self.label.frame = tempFrame;

如果您想根据uilabel宽度更改其字体，请使用以下内容; 注意：仅当self.label.numberOfLines = 1时才有效。

self.label.adjustsFontSizeToFitWidth = YES;
self.label.minimumFontSize = 0;

自定义标签未完全填充数据
