Unable to insert COPY_SEND错误解决

[Common] _BSMachError: port 610b; (os/kern) invalid capability (0x14) "Unable to insert COPY_SEND"

经过debug，console报错是在键盘弹出之后，控制器的view执行y值增加10的动画时报的错，解决办法是在执行动画外层包裹延迟0.3秒执行的代码，如下：

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.3*NSEC_PER_SEC)),dispatch_get_main_queue(), ^{

      [UIViewanimateWithDuration:aniTimeanimations:^{

      self.view.y= -gap-35;

      }];

});
