Question

当我仅从hometabviewcontroller点击特定标签栏时，我遇到了崩溃错误。这只在iOS 11中发生。请帮我解决这个问题。

@interface HomeTabBarController ()

    ChatSocketIOClient *socket;

}
@property (strong, nonatomic) UIButton *onTheJobOffTheJobButton;
@property (strong, nonatomic) NSString *status;
@property LocationTracker * locationTracker;

@end

@implementation HomeTabBarController

    [super viewDidLoad];
    // Crash bug fixing
    self.automaticallyAdjustsScrollViewInsets = NO;
    if (!socket) {
        socket  =[ChatSocketIOClient sharedInstance];
    }

根据请求，以下是我的HomeTabView控制器的整个页面。

    - (void)refresh:(UIRefreshControl *)refreshControl
{
    [refreshControl endRefreshing];
}

当我在iOS 11中点击tabbar-4时，此应用程序崩溃了。我不明白我的代码有什么问题。我没有在Hometabviewcontroller或accountscontroller上获得与refreshController相关的任何代码。但是当我搜索整个代码库时，我得到了以下内容。

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{

    [super viewDidLoad];
     _paymentLogs.selected = YES;

    self.automaticallyAdjustsScrollViewInsets = NO;

   self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: UIColorFromRGB(0XfEAA26)};
}

-(void)getFinancialData{
    UIWindow *window = [[UIApplication sharedApplication]keyWindow];
    [[ProgressIndicator sharedInstance] showPIOnWindow:window withMessge:NSLocalizedString(@"Loading...",@"Loading...")];
    _pastCycle = [[NSMutableArray alloc]init];
    NSDictionary *dict =@{
                          @"ent_sess_token": [[NSUserDefaults standardUserDefaults] objectForKey:KDAcheckUserSessionToken],
                          @"ent_dev_id":  [[NSUserDefaults standardUserDefaults] objectForKey:kPMDDeviceIdKey],
                          @"ent_date_time":[Helper getCurrentDateTime],
                          @"ent_pro_id": [[NSUserDefaults standardUserDefaults] objectForKey:@"ProviderId"]
                          };
    NetworkHandler *handler  =[NetworkHandler sharedInstance];
    [handler composeRequestWithMethod:@"GetFinancialData"
                              paramas:dict
                         onComplition:^(BOOL succeeded, NSDictionary *response) {
                             if (succeeded) {

                                 _currentCycle = response[@"currentCycle"];
                                 NSLog(@"financial data %@",response);
                                 [self.currentTableView reloadData];
                                 [self.pastTableView reloadData];
                                 [[ProgressIndicator sharedInstance] hideProgressIndicator];
                             }
                         }];
}

-(void)viewWillAppear:(BOOL)animated{

}

}

    [pi hideProgressIndicator];
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:
                                @"Main" bundle:[NSBundle mainBundle]];
    iServeSplashController *splah = [storyboard instantiateViewControllerWithIdentifier:@"splash"];
    self.navigationController.viewControllers = [NSArray arrayWithObjects:splah, nil];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
}



-(void)viewDidAppear:(BOOL)animated {
    _pastCycle = [[NSMutableArray alloc]init];
    [self getFinancialData];
    [super viewDidAppear:animated];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(accountDeactivated) name:@"accountDeactivated" object:nil];
}

-(void)viewDidDisappear:(BOOL)animated {

    [super viewDidDisappear:animated];

    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

以下是特定tabview控制器的viewloads代码。

constructor(private renderer:Renderer2, private el: ElementRef ) { }

addfield()  {

  console.log('function triggered');
  const div = this.renderer.createElement('div');
  const input = this.renderer.createElement('input');

  this.renderer.appendChild(div, input);

  this.renderer.addClass(div, 'col-md-6');
  this.renderer.addClass(div, 'col-sm-6');
  this.renderer.addClass(div, 'col-xs-12');

  console.log('cross passes the code');
  this.renderer.addClass(input, 'form-control');
  this.renderer.addClass(input, 'col-md-7');
  this.renderer.addClass(input, 'col-xs-12');

}

Answer 1

您可以跟踪unrecognized selector sent to instance的来源。代码中的某些东西正在调用它。

在hometabviewcontroller或refreshControl的整个项目中进行文字搜索，查看调用它的位置和内容，并确保它符合您的要求。

如果这没有帮助，我们需要更多代码（最好是hometabviewcontroller）来帮助您。
