objective-c – 解析后在单独的类中的UITableView委托和数据源

//HomeViewController.h

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

@interface HomeViewController : UIViewController {

    IBOutlet UITableView *table;
    TableController *tableController;
}

@end

和

//HomeViewController.m

#import "HomeViewController.h"

@interface HomeViewController ()

@end

@implementation HomeViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    tableController = [[TableController alloc] init];
    table.dataSource = tableController.tableSource.dataSource;
    table.delegate = tableController.tableSource.delegate;
    [tableController loadTable]; // HERE I CALL LOADTABLE FROM TABLECONTROLLER CLASS TO PARSE DATA AND POPULATE UITABLEVIEW
    [table reloadData];

}

和

// TableController.h

#import <UIKit/UIKit.h>

@interface TableController : NSObject <UITableViewDelegate,UITableViewDataSource> {

   UITableView *tableSource;

   // a lot of NSMutableArray to parse my data

}

- (void)loadTable;

@property (nonatomic,strong) UITableView *tableSource;

@end

和

//TableController.m

#import "TableController.h"
#import "AFNetworking.h"

@interface TableController ()

@end

@implementation TableController

@synthesize tableSource;

- (void)loadTable {

    NSURL *parseURL = // remote URL to parse Data
    NSURLRequest *request = [NSURLRequest requestWithURL:parseURL];
    AFJSONRequestOperation *parSEOperation = [AFJSONRequestOperation
                                               JSONRequestOperationWithRequest:request
                                               success:^(NSURLRequest *request,NSHTTPURLResponse *response,id JSON) {

                                                   // code to parse Data and NSLog to test operation

                                                   [tableSource reloadData];
                                                   [tableSource setUserInteractionEnabled:YES];
                                                   [tableSource scrollRectToVisible:CGRectMake(0,1,1) animated:YES];

                                               }
                                               failure:^(NSURLRequest *request,NSError *error,id JSON) {
                                                   NSLog(@"%@",[error userInfo]);
                                               }];
    [parSEOperation start];
    [tableSource setUserInteractionEnabled:NO];
}

而且,显然,仍然在TableController.m中,所有经典的UITableView委托方法：

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// my code
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// my code
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
// my code
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
// my code
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
// my code
}

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
// my code
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// my code
}

好吧,解析是完美的(我可以用NSLog测试它),但我的表是空的.你能帮我吗？

编辑：在我的代码中,loadTable解析方法是异步的,所以表加载了正确的数据源和委托但是在解析所有数据之前;实际上如果我设置了一个固定的numberOfRows然后SCROLL TABLE我可以看到填充的所有行.但是,当我加载HomeViewController时,*表仍然是EMPTY.
