我能够从plist获取数据，但似乎没有调用我的cellForRowAtIndexPath，因为没有NSLog从方法内部打印任何内容。
这是我的代码：-
- (void)viewDidLoad
{
NSString *path = [[NSBundle mainBundle] pathForResource:@"drinks" ofType:@"plist"];
NSMutableDictionary *tempDict = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
self.drinks = [tempDict objectForKey:@"Root"];
NSLog(@"%@", self.drinks);
NSLog(@"Number = %d", self.drinks.count);
[super viewDidLoad];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
NSLog(@"I am inside cellForRowAtIndexPath");
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
NSArray *allValues = [self.drinks valueForKey:@"name"];
NSLog(@"%d", allValues.count);
cell.textLabel.text = [allValues objectAtIndex:indexPath.row];
return cell;
}
这是我的控制台输出：-

ingredients = "hasdhalsdlash asdhasldh kjdfkjshdj";
name = "Vodka";
}
)
2011-10-01 20:27:01.942 DrinkMixer[1832:b303] Number = 9
cellForRowAtIndexPath的NSLog没有被调用。
谁能告诉我这段代码有什么问题。
谢谢。
最佳答案
可能是您未在头文件中实现UITableViewDelegate，或者您的nib文件中未连接UITableView和datasource。
我建议签出delegate。
更新：
没有调用datasource且tableView:cellForRowAtIndexPath:设置正确的事实可能是plist已加载后，plist已加载到datasource中。证明可能是向上或向下滚动空白的self.drinks并查看屏幕外的单元格是否开始出现。
我建议两件事：
在您的UITableView开头致电UITableView
加载plist后，要求重新加载UITableView。
尝试：
- (void)viewDidLoad {
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"drinks" ofType:@"plist"];
NSMutableDictionary *tempDict = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
self.drinks = [tempDict objectForKey:@"Root"];
NSLog(@"%@", self.drinks);
NSLog(@"Number = %d", self.drinks.count);
[yourTableView reload];
}
最后，我担心您的
[super viewDidLoad];的原因是因为我认为即使是一个空单元格也应调用-(void)viewDidLoad希望这可以帮助。
