发送到实例的无法识别的选择器(DTCoreText + UILabel)

Question

我收到错误:

-[__NSCFType lineBreakMode]: unrecognized selector sent to instance

当以下代码完成执行时:

 NSDictionary* options = @{ NSTextSizeMultiplierDocumentOption: [NSNumber numberWithFloat: 1.0],
                                                            DTDefaultFontFamily: @"Helvetica Neue",
                                                            };
 NSAttributedString *attrStr = [[NSAttributedString alloc] initWithHTMLData:[@"HTML TEXT HERE" dataUsingEncoding:NSUTF8StringEncoding] options:options documentAttributes:NULL];
 attrStr = [attrStr copy];

 UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
 lbl.attributedText = attrStr;

 UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"MOTD"
                                                 message:@""
                                                delegate:nil
                                       cancelButtonTitle:@"OK"
                                       otherButtonTitles:nil];
 [alert setValue:lbl forKey:@"accessoryView"];
 [self Load_list_Data];
 [alert show];

我的项目针对的是iOS 8+.

有任何想法吗？

出于某种原因,即使我使用iOS 8强制iOS 6属性修复了问题:

     NSDictionary* options = @{ NSTextSizeMultiplierDocumentOption: [NSNumber numberWithFloat: 1.0],
                                DTDefaultFontFamily: @"Helvetica Neue",DTUseiOS6Attributes: [NSNumber numberWithBool:YES],
                                };
