Xcode4 尝试将我的项目更新为ios 7错误-drawInRect已被否决

我正在尝试更新我的应用程序以在IOS 7上工作，但收到一个错误，告诉我以下代码已被弃用并与属性一起使用。苹果开发者网站只是说它已经被弃用了，但没有给出如何修复的线索。有人能把我的代码翻译成任何新的格式吗

[str drawInRect: r
       withFont: f1
  lineBreakMode: NSLineBreakByWordWrapping
      alignment: NSTextAlignmentCenter];

使用以下命令：

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
paragraphStyle.alignment = NSTextAlignmentCenter;
[str drawInRect:rect withAttributes: @{NSFontAttributeName: f1,
                             NSParagraphStyleAttributeName: paragraphStyle }];

试试下面的

NSString *font = @"Courier-Bold";
  #ifdef __IPHONE_7_0
    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
    paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
    paragraphStyle.alignment = NSTextAlignmentCenter;
    [textToDraw drawInRect:renderingRect withAttributes: @{NSFontAttributeName: font,
                                                                       NSParagraphStyleAttributeName: paragraphStyle }];
    #else
    [textToDraw drawInRect:renderingRect withFont:font lineBreakMode:NSLineBreakByWordWrapping alignment:NSTextAlignmentCenter];
    #endif

textToDraw是要绘制的字符串。我希望这会有帮助。

您是否尝试过

drawInRect:withAttributes:

？
