所以我创建了一个子类UITableViewController并将委托和数据源设置为自身。但仍然像这样的方法cellForRowAtIndexPath永远numberOfRowsInSection不会被调用。我numberOfSectionsInTableView每次都返回 1。这就是 viewDidLoad() 的样子

- (void)viewDidLoad {
[super viewDidLoad];
NSMutableArray* list = [[NSMutableArray alloc] init];
self.tableView = [[UITableView alloc] init];
self.tableView.delegate = self;
self.tableView.dataSource = self;
self.actionList = list;
self.clearsSelectionOnViewWillAppear = NO;
self.contentSizeForViewInPopover = CGSizeMake(320.0, 400.0);
[self.actionList addObject:@"t1"];
[self.actionList addObject:@"t2"];
}

当我尝试在弹出窗口中加载它时,我得到的只是一个空白弹出窗口。 这就是我在 UIPopover 中看到的

我在这方面花了很多时间。请帮帮我。

编辑:.m 文件

// KLActionsViewController.m #import "KLActionsViewController.h"

@interface KLActionsViewController ()

@end

@implementation KLActionsViewController
@synthesize actionList,delegate;

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

//- (void)loadView
//{
//    
//}

- (void)viewDidLoad {
    [super viewDidLoad];
    NSMutableArray* list = [[NSMutableArray alloc] init];
    self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320.0, 100.0) style:UITableViewStyleGrouped];
    self.tableView.delegate = self;
    self.tableView.dataSource = self;
    self.actionList = list;
    self.clearsSelectionOnViewWillAppear = NO;
    self.contentSizeForViewInPopover = CGSizeMake(320.0, 200.0);
    [self.actionList addObject:@"t1"];
    [self.actionList addObject:@"t2"];
    [self.tableView reloadData];
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    NSLog(@"in number of section");
    return 1;
}

- (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
    NSString* lab = [self.actionList objectAtIndex:indexPath.row];
//    NSLog(lab);
    NSLog(@"here in there");
    cell.textLabel.text = lab;
    return cell;
}

- (NSInteger)numberOfRowsInSection:(NSInteger)section
{
    NSLog(@"Total entries : %i ",[self.actionList count]);
    return [self.actionList count];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (self.delegate != nil) {
        [self.delegate actionSelected:indexPath.row];
    }
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    self.actionList = nil;
    self.delegate = nil ;
    // Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

.h 文件

#import <UIKit/UIKit.h>

@protocol KLActionsViewControllerDelegate
- (void)actionSelected:(NSInteger)index;
@end

@interface KLActionsViewController : UITableViewController <UITableViewDataSource,UITableViewDelegate>
@property (nonatomic, retain) NSMutableArray* actionList;
@property (nonatomic, assign) id<KLActionsViewControllerDelegate> delegate;

尝试在 viewDidLoad 末尾添加 [self.tableView reloadData]

在 .h 文件中,添加 UITableViewDelegateUITableViewDataSource

像这样的东西:

@interface Yourclass : rootClass <UITableViewDelegate, UITableViewDataSource>

在 .h 文件中试试这个

@interface KLActionsViewController:UIView <UITableViewDelegate,UItableViewDataSource>
