Ios 对IQWidgets库有清晰的理解吗

我正在尝试建立一个甘特图。 我在街上找到了这个图书馆

我下载了它，我试着理解如何使用它

我有一个类，可以从服务器中获取数据（JSON）。我将这些结果指定为

[NSDictionary]

我试图使用

IQGanttView.h

文件，将其添加为当前视图的子视图。

IQGanttView.h

有一个名为

addRow:（id）row

addRow

方法有一个参数

IQCalendarDataSource

，这就是我创建一个类作为

IQCalendarDataSource

（任务对象）的原因。 我将

IQCalendarDataSource

类更改为具有与任务类相同的属性

创建这些任务对象后，我为所有数组（任务对象）创建了一个for循环，通过

addRow：（id）row

方法将它们添加到图表上

我运行代码并遵循它，但它没有在图表上显示任务

我不知道我是否错过了什么？ 有人能查一下图书馆，告诉我是否遗漏了什么吗

=================

这是我正在尝试的代码

#import "GanttChartViewController.h"
#import "ASRESTAPI.h"
#import "ASUserSingleton.h"
#import "TasksObj.h"
#import "IQGanttView.h"

// when the view load I want to show the user the loading view until the data is ready to show up on the chart by calling [self setupLoadingIndicator] method
// 
- (void)viewDidLoad {
    [super viewDidLoad];
    tasksItems = [[NSArray alloc] init];
    self.ganttView = [[IQGanttView alloc] initWithFrame:self.view.bounds];
    [self.view addSubview:self.ganttView];
    [self setupLoadingIndicator];
    // Do any additional setup after loading the
    [self gettheTasksItems];
}

-(void)setupLoadingIndicator
{
    loadingView = [[UIView alloc] initWithFrame:CGRectMake(75, 155, 170, 170)];
    loadingView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
    loadingView.clipsToBounds = YES;
    loadingView.layer.cornerRadius = 10.0;

    activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    activityView.frame = CGRectMake(65, 40, activityView.bounds.size.width, activityView.bounds.size.height);
    [loadingView addSubview:activityView];

    loadingLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 115, 130, 22)];
    loadingLabel.backgroundColor = [UIColor clearColor];
    loadingLabel.textColor = [UIColor whiteColor];
    loadingLabel.adjustsFontSizeToFitWidth = YES;
    loadingLabel.textAlignment = NSTextAlignmentCenter;
    loadingLabel.text = @"Loading...";
    [loadingView addSubview:loadingLabel];
    [self.ganttView addSubview:loadingView];
    [activityView startAnimating];
}


-(void)gettheTasksItems
{

    NSString* username = [[ASUserSingleton sharedInstance]userName];
    NSString* password = [[ASUserSingleton sharedInstance]password];
    _tasks = nil;
    [ASRESTAPI tasksListUsername:username andPassword:password completionBlock:^(NSDictionary *response, NSArray *taskArray) {
        _tasks = response;
        tasksItems = taskArray;

        NSMutableArray *tasksObjs = [NSMutableArray array];
        int i;
        for (i =0; i < tasksItems.count;i++)
        {
            /*_tasks[@"project"][@"name"]*/ // this is how to call the dictionary object from the array
            TasksObj* tasksObj = [[TasksObj alloc]initWithProjectName:tasksItems[i][@"project"][@"name"]
                                                               startDate:tasksItems[i][@"start_date"]
                                                                 dueDate:tasksItems[i][@"due_date"]
                                                          estimatedhours:tasksItems[i][@"estimated_hours"]];
            //tasksItems[i] objectForKey:@"project"];
            [tasksObjs addObject:tasksObj];
        }
        dispatch_async(dispatch_get_main_queue(), ^{
            [activityView stopAnimating];
            for (loadingView in [self.ganttView subviews])
            {
                [loadingView removeFromSuperview];
            }
            //[loadingView removeFromSuperview];
            for (TasksObj* tasksObj in tasksObjs) {
                [self.ganttView addRow:tasksObj];
            }

        });

    }];
}

顺便说一下，这是我从服务器获取的JSON数据

请发布您尝试过的代码。好的，我将编辑我的帖子，以便您可以查看。谢谢你的评论！！真的谢谢你。
