Question

我的目标是在UIViewController中设置两个（或更多）tableView。我正在使用Vurig日历，但它没有tableviews，所以我试图自己做。一个tableView来自外部，看起来不错。当我尝试将委托和数据源设置为自身时，另一个中断。代码是：

#import <UIKit/UIKit.h>
#import "VRGCalendarView.h"

#import "ListViewController.h"
//#import "DayTableViewController.h"

@interface CalendarViewController : UIViewController <VRGCalendarViewDelegate,    UITableViewDelegate,UITableViewDataSource>
{
VRGCalendarView *calendar;
// DayTableViewController *dayViewController;
ListViewController *listViewController;

}

@property (nonatomic, weak) IBOutlet UITableView *monthView;
@property (nonatomic, weak) IBOutlet UITableView *listView;
@property (nonatomic, weak) IBOutlet UISegmentedControl *segControl;
- (IBAction)segmentedValueChanged:(UISegmentedControl *)sender;

@end

CalendarViewController.m：

#import "CalendarViewController.h"
#import <EventKit/EventKit.h>

@interface CalendarViewController () 


@property (nonatomic, strong) EKEventStore *eventStore;
@property (nonatomic, strong) NSMutableArray *events;

@end

@implementation CalendarViewController

@synthesize eventStore;
@synthesize events;
@synthesize monthView = _monthView;
@synthesize listView = _listView;

 -(void)viewDidLoad{

[super viewDidLoad];

[_segControl addTarget:self  action:@selector(segmentedValueChanged:) forControlEvents:UIControlEventValueChanged];
[_segControl setSelectedSegmentIndex:1];


//kalendar
calendar = [[VRGCalendarView alloc] init];

calendar.delegate=self;
[self.view addSubview:calendar];



//lista
if (listViewController == nil)
{
    listViewController = [[ListViewController alloc] init];
}
[_listView setDataSource:listViewController];
[_listView setDelegate:listViewController];
listViewController.view = listViewController.tableView;
_listView.hidden = YES;


/*
if (dayViewController == nil)
{
    dayViewController = [[DayTableViewController alloc] init];
}
[monthView setDataSource:dayViewController];
[monthView setDelegate:dayViewController];
dayViewController.view = dayViewController.tableView;
 */

//eventi
NSDate *startDate = [NSDate date];
NSDate *endDate = [NSDate dateWithTimeIntervalSinceNow:(60 * 60 * 24)];
// Create the predicate from the event store's instance method

NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate

                                                              endDate:endDate

                                                            calendars:nil];

NSArray *results = [self.eventStore eventsMatchingPredicate:predicate];
NSMutableArray *eventsi = [[NSMutableArray alloc] initWithArray:results];
self.events = eventsi;

[_monthView setDataSource:self];
[_monthView setDelegate:self];
_monthView.hidden = NO;
//[monthView reloadData];

}

  -(void)calendarView:(VRGCalendarView *)calendarView switchedToMonth:(int)month targetHeight:(float)targetHeight animated:(BOOL)animated {
if (month==[[NSDate date] month]) {

    // prazan array za prikaz
    NSMutableArray *dates = [[NSMutableArray alloc] init];

    NSDate* endDate =  [NSDate dateWithTimeIntervalSinceNow:[[NSDate distantFuture] timeIntervalSinceReferenceDate]];
    NSPredicate *fetchCalendarEvents = [eventStore predicateForEventsWithStartDate:[NSDate date] endDate:endDate calendars:nil];
    NSArray *eventList = [eventStore eventsMatchingPredicate:fetchCalendarEvents];

    for (int i = 0; i < [eventList count]; i++)
    {
        NSLog(@"Event Title:%@", [[eventList objectAtIndex:i] title]);
        NSDate *today = [NSDate date];
        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"dd"];
        NSString *dayInMonthStr = [dateFormatter stringFromDate:today];

        // tu dobijemo integer od tog dana
        int dayInMonth = [dayInMonthStr intValue];

        // dodamo taj datum u array
        [dates addObject:[NSString stringWithFormat:@"%i", dayInMonth]];
    }

    // na kraju prikazemo
    [calendarView markDates:dates];
}

}


-(void)calendarView:(VRGCalendarView *)calendarView dateSelected:(NSDate *)date {
NSLog(@"Selected date = %@",date);

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

// Return the number of sections.
return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.events count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

if (cell == nil)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] ;
}
EKEvent * event = [self.events objectAtIndex:indexPath.row];
cell.textLabel.text = event.title;

cell.detailTextLabel.text = event.calendar.title;

if (event.calendar.CGColor) {
    cell.detailTextLabel.textColor = [UIColor colorWithCGColor:event.calendar.CGColor];
}


return cell;
 }

 //segment part
 - (IBAction)segmentedValueChanged:(UISegmentedControl *)sender
{
switch (sender.selectedSegmentIndex) {
    case 0:
    {
        _listView.hidden = NO;
        [_listView reloadData];
        calendar.hidden = YES;
        _monthView.hidden = YES;
    }
        break;
    case 1:

        calendar.hidden = NO;
        _monthView.hidden = NO;
        [_monthView reloadData];
        _listView.hidden = YES;

        break;

    default:
        break;
}
}

- (void)didReceiveMemoryWarning
 {
[super didReceiveMemoryWarning];


 }
@end

在IB中连接了monthView（IBOutlet，源代码和委托与CalendarViewController）。我看不出我做错了什么。

UIViewController不会加载UITableView
