UIButton隐藏了花费很多时间隐藏在ios中

Question

当我输入此viewController时，我正在调用此loadView方法。之后，我在getStatus

中调用另一个函数viewDidLoad

-(void)loadView
{

  CGRect frame = [UIScreen mainScreen].bounds;
  self.view = [[UIView alloc] init];
  self.view.frame = CGRectMake(0, 0, frame.size.width, frame.size.height);
  self.view.backgroundColor = [UIColor colorWithRed:19.0/255.0 green:155.0/255.0 blue:235.0/255.0 alpha:1];

  footerView = [[UIView alloc] init];
  footerView.frame = CGRectMake(0, frame.size.height-60, screenwidth, 60);
  [footerView setBackgroundColor:[UIColor colorWithRed:19.0/255.0 green:155.0/255.0 blue:235.0/255.0 alpha:1]];
  [self.view addSubview:footerView];

  deleteBotl = [UIButton buttonWithType:UIButtonTypeCustom] ;
  [deleteBotl setImage:[UIImage imageNamed:@"delete_botl.png"] forState:UIControlStateNormal];
  deleteBotl.frame =CGRectMake(screenwidth/2+115,footerView.frame.size.height/2-20, 40, 40);
  deleteBotl.showsTouchWhenHighlighted = YES;
  [footerView addSubview:deleteBotl];
  [deleteBotl addTarget:self action:@selector(deleteBotl) forControlEvents:UIControlEventTouchDown];


  reportBtn = [UIButton buttonWithType:UIButtonTypeCustom] ;
  [reportBtn setImage:[UIImage imageNamed:@"report_botl.png"] forState:UIControlStateNormal];
  reportBtn.frame = CGRectMake(screenwidth/2+115,footerView.frame.size.height/2-20, 40, 40);
  reportBtn.showsTouchWhenHighlighted = YES;
  [footerView addSubview:reportBtn];
  [reportBtn addTarget:self action:@selector(reportWithDefaultAlert) forControlEvents:UIControlEventTouchDown];

  removeBotl = [UIButton buttonWithType:UIButtonTypeCustom] ;
  [removeBotl setImage:[UIImage imageNamed:@"remove_botl.png"] forState:UIControlStateNormal];
  removeBotl.frame = CGRectMake(screenwidth/2+115,footerView.frame.size.height/2-20, 40, 40);
  removeBotl.showsTouchWhenHighlighted = YES;
  [footerView addSubview:removeBotl];
  [removeBotl addTarget:self action:@selector(removeBotl) forControlEvents:UIControlEventTouchDown];

}

我在viewDidLoad中调用的此方法此getStatus函数正在调用服务并获取响应。基于该响应，我正在进行隐藏并取消隐藏buttons。隐藏和取消隐藏是可行的，但隐藏和取消隐藏需要很长时间。我很快得到了答复。但这需要很长时间。

-(void) getStatus
