不明白爲什麼的cellForRowAtIndexPath不會被調用,即使numberOfRowsInSection被稱爲 我把這個視圖控制器與的cellForRowAtIndexPath不會觸發

ServerDataController * DataController類= [[ServerDataController頁頭] initWithNibName:@ 「ServerDataController」 捆綁:零];

[self presentModalViewController:dataController animated:YES];

這裏是我的代碼: 頭文件

#import <UIKit/UIKit.h> 

@interface ServerDataController : UIViewController <NSXMLParserDelegate, NSURLConnectionDelegate, UITableViewDataSource> 
{ 
... 
    NSMutableArray *items; 
    UITableView *docsTableView; 

} 
@property (retain, nonatomic) IBOutlet UITableView *docsTableView; 

@property (nonatomic, readonly) NSMutableArray *items; 

@end 

實現文件:

#import "ServerDataController.h" 

@implementation ServerDataController 
@synthesize docsTableView; 
@synthesize items; 


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

- (id)init 
{ 
    self = [super init]; 

    if (self) 
    { 

    } 

    return self; 
} 


- (void)dealloc { 

    [items release]; 
    [docsTableView release]; 
    [super dealloc]; 
} 

- (void)viewDidAppear:(BOOL)animated 
{ 
    [self fetchEntries]; 
    animated = YES; 
} 

- (void)didReceiveMemoryWarning 
{ 
    // Releases the view if it doesn't have a superview. 
    [super didReceiveMemoryWarning]; 

    // Release any cached data, images, etc that aren't in use. 
} 

#pragma mark - View lifecycle 

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

    if (self) { 
     items = [[NSMutableArray alloc] init]; 
    } 
} 



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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath; 
{ 
    static NSString *CellIdentifier = @"Cell"; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
    } 
    NSString *cellTitle = [[[[items objectAtIndex:indexPath.row] docUrl] lastPathComponent] stringByDeletingPathExtension]; 

    cell.textLabel.text = cellTitle; 
    return cell; 
} 

有什麼建議?

我沒有看到你的項目添加到你的數組,只有你的viewDidLoad中的init,我認爲它是空的,所以這就是爲什麼函數永遠不會被調用。根本沒有任何項目要顯示。

我在解析XML文件時添加了項目,並沒有包含那麼大的代碼。陣列不是空的肯定。 cellForRowAtIndexPath無論如何應該觸發 – Oleg 2012-04-24 20:16:56

好吧,一個遠射,但你會驚訝愚蠢的東西,我寫了我的代碼時,東西看起來:)爲什麼你的控制器UIViewController而不是UITableViewController?我認爲你應該實現UITableViewDelegate,如果你是一個普通的UIViewController而不是UITableViewController – verhage 2012-04-24 20:20:50
