添加的Dropbox文件要UITableView的

Question

我想我的Dropbox文件加載到一個UITableView，但他們都沒有顯示出來。我完成了在dropbox.com上註冊我的應用程序並在我的應用程序中實施會話委託的每一步。這裏是我的代碼，任何人都可以告訴我它有什麼問題。林相當肯定，我宣佈一切正常，但我似乎無法找到問題。另外我知道它不是連接問題，因爲我添加了NSLog並記錄了這些文件。

#import <UIKit/UIKit.h> 
#import <DropboxSDK/DropboxSDK.h> 

@interface testViewController : UITableViewController <DBRestClientDelegate> 
{ 
    DBRestClient *restClient; 
    NSMutableArray *dropboxURLs; 
} 
@end 

#import "testViewController.h" 

@interface testViewController() 

@end 




@implementation testViewController 

- (id)initWithStyle:(UITableViewStyle)style 
{ 
    self = [super initWithStyle:style]; 
    if (self) { 
     // Custom initialization 
    } 
    return self; 
} 

- (DBRestClient *)restClient { 
    if (!restClient) { 
     restClient = 
     [[DBRestClient alloc] initWithSession:[DBSession sharedSession]]; 
     restClient.delegate = self; 
    } 
    return restClient; 
} 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    dropboxURLs = [[NSMutableArray alloc] init]; 
    [[self restClient] loadMetadata:@"/"]; 
} 

- (void)restClient:(DBRestClient *)client loadedMetadata:(DBMetadata *)metadata { 
    if (metadata.isDirectory) { 
     for (DBMetadata *file in metadata.contents) { 
      if (!file.isDirectory) 
      { 
       NSLog(@"%@", file.filename); 
       [dropboxURLs addObject:file.filename]; 
      } 
     } 
    } 
} 

- (void)restClient:(DBRestClient *)client 
loadMetadataFailedWithError:(NSError *)error { 

    NSLog(@"Error loading metadata: %@", error); 
} 


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

#pragma mark - Table view data source 

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

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    // Return the number of rows in the section. 
    return dropboxURLs.count; 
} 

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

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

    cell.textLabel.text = [dropboxURLs objectAtIndex:indexPath.row]; 

    return cell; 
} 

@end 

Answer 1

將內容添加到dropboxURLs數組後，重新載入表視圖。

[self.tableView reloadData]; 

Answer 2

嘗試這樣的事情你ADDOBJECT調用後立即：

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade]; 

Answer 3

-(void)restClient:(DBRestClient *)client loadedMetadata:(DBMetadata *)metadata { 
    if (metadata.isDirectory) { 
     for (DBMetadata *file in metadata.contents) { 
      if (!file.isDirectory) 
      { 
       NSLog(@"%@", file.filename); 
       [dropboxURLs addObject:file.filename]; 
      } 
     } 
    } 
    [self. tableView reloadData]; 
    } 

不要忘了的UITableView的委託和數據源設置爲自我。

Answer 4

• 我們必須
• 元數據之後被加載從DropBoxRoot
加載數據，重新加載的tableview

• （無效）viewDidLoad中{
  [超級viewDidLoad中];
  dropboxURLs = [[NSMutableArray裏的alloc] INIT];
  [self loadData];
  }

-(void) loadData{ 
if ([DBSession sharedSession].root == kDBRootDropbox) { 
    photosRoot = @"/";//can specify any folder like /Photos,/Public etc 
} 
[self.restClient loadMetadata:photosRoot withHash:photosHash]; 
} 


- (void)restClient:(DBRestClient*)client loadedMetadata:(DBMetadata*)metadata { 

photosHash = metadata.hash; 

NSArray* validExtensions = [NSArray arrayWithObjects:@"jpg", @"jpeg",@"png",@"txt",@"pdf",@"doc",@"mp3",@"mp4", nil]; 
for (DBMetadata* child in metadata.contents) { 

    NSString* extension = [[child.path pathExtension] lowercaseString]; 

    if (!child.isDirectory && [validExtensions indexOfObject:extension] != NSNotFound) { 
     [directory addObject:child.filename]; 
    }else{ 
     [allFileAndDirectory addObject:child.filename]; 
    } 
    [myTableView reloadData]; 
}
