我正在尝试创建CocoaPod，但是当我尝试验证Pod规格文件时，请向我显示此错误。

这是我的podspec文件。

当我尝试使用iOS 8编译iOS项目时遇到问题.

    }
} 

class Refund extends Model {
  protected $guarded = array();

  public static $rules = array(
    'request_id' => 'required',
    'beneficiary_id' => 'required',
    'concept' => 'required',
    'date' => 'required | date_format:Y-m-d',
    'amount' => 'required | min:-1 | numeric',
    'deductible_amount' => 'required | numeric',
    'max_applied' => 'required | numeric',
    'yearly_balance' => 'required | numeric',
    'payment_amount' => 'required | min:-1 | numeric',
    'payment_date' => 'required | date_format:Y-m-d',

我正在尝试在我的项目中实现动态属性 这是我的代码。

我的类.h

@interface MyClass : UIView

@property (strong, nonatomic) NSString *name;

@end

我的课堂.m

@implementation MyClass

@dynamic name;

-(void)setName:(NSString *)name{
   self.name = name;
}
@end

但是当我运行时，我的应用程序崩溃了。

当我使用 ivar 时出现此错误。
