Question

这是我的教导部分,在这里,我正在从Xml档案中获取属性和价值。现在,Xml将同时 par平时,表层的特性和价值就应逐字显示。

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ 
//NSLog(@"found this element: %@", elementName); 
currentElement = [elementName copy]; 
if([elementName isEqualToString:@"ProductData"])
    {
    objectsArray = [[NSMutableArray alloc] init];
    productDict = [[NSMutableDictionary alloc] init];
   }

} 
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ 
//NSLog(@"found characters: %@ %@", currentElement,string);
if(!currentString){
    currentString = [[NSMutableString alloc] init];
}
[currentString appendString:string]; 
} 
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:   (NSString *)namespaceURI qualifiedName:(NSString *)qName{ 
//NSLog(@"ended element: %@", elementName); 
if([elementName isEqualToString:@"id"])
{
    [productDict setObject:currentString forKey:@"id"];
    [self labelsetting:0];
    [currentString release],currentString = nil;

    return;
}
if([elementName isEqualToString:@"productNumber"])
{
    [productDict setObject:currentString forKey:@"productNumber"];
    [self labelsetting:0];
    [currentString release],currentString = nil;
    return;
}
if([elementName isEqualToString:@"name"])
{
    [productDict setObject:currentString forKey:@"name"];
    [self labelsetting:0];
    [currentString release],currentString = nil;
    return;
}
if([elementName isEqualToString:@"dateCreated"])
{
    [productDict setObject:currentString forKey:@"dateCreated"];
    [self labelsetting:0];
    [currentString release],currentString = nil;
    return;
}
if([elementName isEqualToString:@"image"])
{
    [productDict setObject:currentString forKey:@"image"];
    [self labelsetting:0];
    [currentString release],currentString = nil;
    return;
}
if([elementName isEqualToString:@"ProductData"])
{
    [objectsArray addObject:productDict];

    [productDict release],productDict = nil;
}
[currentString release], currentString = nil;


}

下表是我想要显示xml数据的情况。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section    { 
return [objectsArray count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
    //cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
    cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:15.0];


}


productDict = [objectsArray objectAtIndex:indexPath.row];

NSString *data = nil;
for (NSString *key in [productDict allKeys] ) {
   // [data stringByAppendingFormat:@"%@ %@",key,[productDict objectForKey:key]];
    data = [NSString stringWithFormat:@"%@%@", key,[productDict objectForKey:key]];

    NSLog(@"data: %@",data);

}
cell.textLabel.text = data;

return cell;
[data release];
}

This the console of this view controller

现在,我认为你已经提出问题。

Answer 1

    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
            return 1;
    }
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {  
            return [objectsArray count];
    }

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    

            static NSString *CellIdentifier = @"Cell";

            UITableViewCell *currentCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

            if (currentCell == nil) {
                currentCell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
            }
            NSMutableDictionary *productDict = [objectsArray objectAtIndex:indexPath.row];
NSString *data = nil;
    for (NSString *key in [productDict allKeys] ) {
        [data stringByAppendingFormat:@"%@",key,[dic objectForKey:key]];
    }
            currentCell.textLabel.text = data;

            return currentCell;
    }
