我剛剛安裝了與ios5的xcode 4.2.1,我嘗試使用json。json ios5在屏幕上沒有任何東西
這是我的代碼
-(void)start
{
responseData = [[NSMutableData data]retain];
membreArray = [NSMutableArray array];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http:******.php"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[responseData setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[responseData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"error %@",error);
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
[responseData release];
jsonArray = [responseString JSONValue];
NSLog(@"array %@",jsonArray);
}
我
NSLog(@"array %@",jsonArray);
我可以看到所有的記錄,一切正常
。但在我的桌面屏幕上沒有任何東西。
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [jsonArray count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
// Configure the cell.
NSDictionary *dico = [self.jsonArray objectAtIndex:indexPath.row];
cell.textLabel.text = [dico objectForKey:@"name"];
return cell;
}
上的Xcode 3此代碼的工作,但不是在Xcode 4
薩姆幫助請。
