Question

在我的应用程序中，我有一个要显示的新闻列表，我正在使用自定义tableview，其中包含标题，缩略图和更多按钮。点击更多按钮，将进入具有描述的详细视图。我已经解析了JSON响应以列出页面中的feed。但我对细节页面感到震惊。以下是我的代码：

.m文件

@interface NewsViewController ()

@property (nonatomic , retain) NSMutableArray *mArray;
@property (nonatomic , retain) NSDictionary *nDic;
@end

@implementation NewsViewController

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

- (void)viewDidLoad
{ 
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://almithaq.mawaqaademo11.com/API.svc/getNews" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

    self.nDic = (NSDictionary *)responseObject;
    self.mArray = self.nDic[@"News"];
    [self.mTab reloadData];
    NSLog(@"response dateJSON: %@", self.mArray);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
}

#pragma mark - TableConfiguration
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;

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

}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *Identifier = @"MyIdentifier";


NewsCell *cell12 = (NewsCell *)[tableView dequeueReusableCellWithIdentifier:Identifier];
if (cell12 == nil) {
    NSArray *nib = [[NSBundle mainBundle]loadNibNamed:@"NewsCell" owner:self options:nil];
    cell12 = [nib objectAtIndex:0];
}


cell12.newsDescription.text = [[self.mArray objectAtIndex:indexPath.row] objectForKey:@"Description"];
cell12.newsTitle.text = [[self.mArray objectAtIndex:indexPath.row] objectForKey:@"Title"];

cell12.newsThumbnail.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://%@",[[self.mArray objectAtIndex:indexPath.row] objectForKey:@"NewsImage"]]]]];

cell12.newsMore.tag = indexPath.row;
[cell12.newsMore addTarget:self action:@selector(NewsClicked:) forControlEvents:UIControlEventTouchUpInside];

return cell12;

  }
 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
  {
return 220;
  }

  -(void)backButtonClicked:(UIButton*)sender
  {
if (sender.tag <= 25)
{
    [self.navigationController popViewControllerAnimated:YES];
}

 }

  -(void)NewsClicked:(UIButton *)sender
   {
if (sender.tag <= 25) {
    NewsDetails *view1 = [[NewsDetails   alloc]initWithNibName:@"NewsDetails" bundle:nil];
    [self.navigationController pushViewController:view1 animated:YES];
}}

建议，提前谢谢。
