我有一個UITableView,我想從一個對象數組中填充細節。 tableview在每一行顯示相同的項目(正確的行數雖然!)我知道這一定是一個容易的 - 但我不明白我出錯的地方:我的UITableView在每一行顯示相同的項目
初始化的代碼片段表中的數據:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:@"Show Tank List"])
{
NSURL *myUrl = [[NSURL alloc]initWithString:@"http://localhost/~stephen-hill9/index.php"];
NSData *data = [[NSData alloc] initWithContentsOfURL:myUrl];
NSError *error;
NSArray *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
int i;
NSMutableArray *tanksList;
tank *thisTank = [[tank alloc] init];
tanksList = [[NSMutableArray alloc] init];
for (i=0; i<json.count; i++) {
NSDictionary *bodyDictionary = [json objectAtIndex:i];
thisTank.tankNumber = [bodyDictionary objectForKey:@"ID"];
thisTank.tankProduct = [bodyDictionary objectForKey:@"Product_Desc"];
thisTank.tankPumpableVolume = [bodyDictionary objectForKey:@"Pumpable"];
[tanksList addObject:thisTank];
}
[segue.destinationViewController setTanks:tanksList];
}
}
...並加載在接下來的視圖中的表的代碼...
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;//keep this section in case we do need to add sections in the future.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [self.tanks count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Tank List Table Cell";
UITableViewCell *cell = [self.tankTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithFrame:CGRectZero];
}
tank *thisTank = [self.tanks objectAtIndex:indexPath.row];
cell.textLabel.text = thisTank.tankNumber;
return cell;
}
完美!謝謝!我認爲這會很容易! :-)我認爲通過初始化循環外的坦克我只需更改值並有效添加對象的副本......再次感謝! :-) – HillInHarwich 2012-03-26 10:10:53
