Question

我似乎无法找到我的错误，任何人都可以帮助我吗？当我尝试运行测试应用程序时它可以工作，但是当我点击Calendar segue时，它会显示一个空白的uitableview列表。我想让它向我展示文本中的“事件”

我的NSLOG关于阵列的详细信息：

2014-08-08 17：38：28.391 nths [2899：607]阵列内容:( “{\ n Date = \”9/14/14 \“; \ n信息= \”太太。福特的房间\“; \ n事件=会议; \ n}”， “{\ n Date = \”9/14/19 \“; \ n信息= \”ford room \“; \ n event = \”午餐在bravos \“; \ n}” ）

以下是我认为会对此产生影响的所有代码。

CalendarViewController.h

#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#import "DataCellViewController.h"

@interface CalendarViewController : UIViewController <UITableViewDelegate> {
    NSArray *eventArray;
}

@property (weak, nonatomic)IBOutlet UITableView *Datatable;

@end

CalendarViewController.m

#import "CalendarViewController.h"

@interface CalendarViewController ( )

@end

@implementation CalendarViewController

@synthesize Datatable;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    [self performSelector:@selector(retrieveFromParse)];
}

- (void) retrieveFromParse {

    PFQuery *retrieveDate = [PFQuery queryWithClassName:@"Calendar"];

    [retrieveDate findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
           NSLog(@"%@",objects);
    if (!error) {
            eventArray = [[NSArray alloc] initWithArray:objects];
        }
        [Datatable reloadData];
    }];
}

//Setup table of folder names

//get number of sections in tableview
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 1;
}

//get number of rows by counting number of folders
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return eventArray.count;
    }

   //setup cells in tableView
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath        *)indexPath

    {

    //setup cell
    static NSString *CellIdentifier = @"CalenderCell";
    DataCellViewController *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
            cell = [[DataCellViewController alloc] initWithStyle:UITableViewCellStyleDefault    reuseIdentifier:CellIdentifier];
        }


// Configure the cell...

        NSDictionary *tempDict = [eventArray objectAtIndex:indexPath.row];

        cell.eventTitle.text = [tempDict objectForKey:@"event"];


    NSLog(@"array contents: %@", eventArray);

   return cell;
}



    - (void)didReceiveMemoryWarning
    {
       [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
    }

@end

DataCellViewController.h

    #import <UIKit/UIKit.h>

    @interface DataCellViewController : UITableViewCell

    @property (nonatomic, strong)IBOutlet UILabel *eventTitle;

    @end

DataCellViewController.m

#import "DataCellViewController.h"

@interface DataCellViewController ( )

@end

@implementation DataCellViewController

@synthesize eventTitle;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
       // Initialization code
     }
    return self;
 }

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];
    // Configure the view for the selected state
}

@end

我的数组中的文本没有以我的表格视图单元格结尾
