TTTableViewController和JSon

Question

我在加载tableview中的数据时出现问题。当视图加载时，我看到表格，但没有填充单元格。

PMs.h

@interface Pms : TTTableViewController { 
NSArray *rows; 
TTTableSubtitleItem *item; 
} 
@property (retain,nonatomic) NSArray *rows; 

PMs.m

- (void)dealloc { 
[rows release]; 
[super dealloc]; 

} 
- (id)init { 
//[self.navigationController setNavigationBarHidden:NO]; 
if (self = [super init]) { 
    self.variableHeightRows = YES; 
    self.dataSource = nil; 

} 
return self; 
} 



-(void)getLatest{ 

NSURL *url = [NSURL URLWithString:@"http://URL.com/pms.php"]; 
NSString *jsonreturn = [[NSString alloc] initWithContentsOfURL:url]; 

NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding]; 
NSError *error = nil; 

// In "real" code you should surround this with try and catch 
NSDictionary * dict = [[[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error] retain]; 
NSMutableArray *zodiaq = (NSMutableArray *)[[dict objectForKey:@"users"] retain]; 
TTListDataSource* tableItems = [[[TTListDataSource alloc] init] autorelease]; 

for(NSDictionary *dict in zodiaq){ 
    item = [TTTableSubtitleItem itemWithText:[dict objectForKey:@"from_user"] subtitle:[dict objectForKey:@"subject"] 
            imageURL:nil 
           defaultImage:nil 
             URL:@"tt://tableItemTest" 
           accessoryURL:nil]; 

    [tableItems.items addObject:item];  
} 
self.dataSource = [TTListDataSource 
        dataSourceWithItems:tableItems.items]; 

[jsonreturn release]; 
} 

- (void)loadView { 
[super loadView]; 
[self setTableViewStyle:UITableViewStylePlain]; 
self.tableView.frame = CGRectMake(0, 44, 320, 396); 
[self getLatest]; 

} 


- (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. 
} 

- (void)viewDidUnload { 
// Release any retained subviews of the main view. 
// e.g. self.myOutlet = nil; 
} 



@end 

当我做

NSLog(@"Data: %@",[dict objectForKey:@"subject"]); 

如果被检索显示所有的主题行，但不填充表。

而不是

self.dataSource = [TTListDataSource 
        dataSourceWithItems:tableItems.items]; 

为什么你不这样做呢？

self.dataSource = tableItems; 

您可能还需要寻找到创建模型去与你的数据源 - 也就是说，扩展TTModel类（或TTURLRequestModel，因为你是在做一个URL请求）。
