没有为UITableView调用numberOfRowsInSection

Question

我有一些问题,我的UITableView没有重新加载,我重做了插座的链接,以确保不是问题.我也尝试过使用[self table] reloadData],但这似乎也不起作用.我已经调试了这些问题,但它只是跳过reloadData而且应用程序一直在运行,就像代码甚至不存在一样.

我的.m文件的顶部,在ViewDidLoad中没有任何操作

#import "SettingsCourses.h"

@implementation SettingsCourses
@synthesize settingsCourses;
@synthesize Delegate;
@synthesize BackButton;
@synthesize DeleteButton;
@synthesize table;
@synthesize courses;
@synthesize dataHandler;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
    // Custom initialization
    dataHandler = [[DataHandler alloc] init];
    dataHandler.coursesDelegate = self;
    courses = [dataHandler fetchCourses];
    NSLog(@"Debug Count: %i", [courses count]);
}
[table reloadData];
return self;
}

- (void) viewWillAppear:(BOOL)animated {
[table reloadData];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (courses) {
    NSLog(@"Count: %i", [courses count]);
    return [courses count];
}
else {
    NSLog(@"Count: 0");
    return 0;
}
}

我的.h文件

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

@interface SettingsCourses : UIViewController 

@property (strong, nonatomic) DataHandler *dataHandler;
@property (strong, nonatomic) NSMutableArray *courses;
@property (strong, nonatomic) IBOutlet UIView *settingsCourses;
@property (nonatomic, strong) id Delegate;
@property (weak, nonatomic) IBOutlet UIButton *BackButton;
@property (weak, nonatomic) IBOutlet UIButton *DeleteButton;
@property (weak, nonatomic) IBOutlet UITableView *table;


- (IBAction)Delete:(id)sender;
- (IBAction)Back:(id)sender;

谢谢你的帮助!

添加以下行:

- (void)viewDidLoad {
  [super viewDidLoad];

  self.table.dataSource = self;
  self.table.delegate = self;
}

但更容易在interface-build(即XIB文件)中设置数据源.
