流JSON來實現代碼如下

Question

我還有一個問題，這個時候，我取將被用來填充的tableview我在我的廈門國際銀行這樣的JSON代碼，開始與我的.h文件中

@interface FirstViewController : UIViewController<UITableViewDelegate, UITableViewDataSource, ASIHTTPRequestDelegate> { 
NSMutableArray *resultArray; 
IBOutlet UITableView *thetableView; 
NSMutableData *responseData; 

}

@property (nonatomic,retain) NSArray *arrayTypes; 
@property (nonatomic,retain) NSMutableArray *resultArray; 
@property (nonatomic,retain) IBOutlet UITableView *thetableView; 

在我的.m文件

我在connectiondidfinishloading實現了這個

- (void) viewDidLoad{ 
responseData = [[NSMutableData data]retain]; 
NSURL *url = [NSURL URLWithString:@"http://localhost/fetch.php"]; 
NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
[[NSURLConnection alloc] initWithRequest:request delegate:self];  
[super viewDidLoad]; 
[self.thetableView reloadData]; 
} 

：

- (void)connectionDidFinishLoading:(NSURLConnection *)connection { 
[connection release]; 

NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
[responseData release]; 
NSLog(@"%@", responseString); 
NSDictionary *dictionary = [responseString JSONValue]; 
NSMutableArray *response = [dictionary valueForKey:@"itemn"]; 
resultArray = [[NSArray alloc] initWithArray:response]; 

}

現在的問題，實現代碼如下實施了兩個numberofrowsinsection和didselectrowatindextpath方法，但後者從來沒有所謂的數組的大小爲0，甚至重裝，它不工作時我錯過了什麼或者是否有類似的教程要遵循？遺憾的長度只是希望將相關信息將是有益的

你應該重新加載tableview中，一旦你有完整的data..see更新的代碼

- (void)connectionDidFinishLoading:(NSURLConnection *)connection { 
[connection release]; 

NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
[responseData release]; 
NSLog(@"%@", responseString); 
NSDictionary *dictionary = [responseString JSONValue]; 
NSMutableArray *response = [dictionary valueForKey:@"itemn"]; 
resultArray = [[NSArray alloc] initWithArray:response]; 

//Reload your table with data.. 
[self.thetableView reloadData]; 
}
