我在将数组插入表视图时遇到问题。我有一个数组,我把它存储在alDescArray
。
通过NSLog打印的是alDescArray = (
"Block1",
"Block2",
"Block3"
)
。当错误时,表格没有显示我的代码的哪一部分?
- (void)viewDidLoad
{
NSArray *BusRoute = alightDesc;
int i;
int count = [BusRoute count];
for (i = 0; i < count; i++)
{
NSDictionary *dic = [BusRoute objectAtIndex: i];
NSDictionary *STEPS = [dic valueForKey:@"STEPS"];
alDescArray = [STEPS valueForKey:@"AlightDesc"];
}
[super viewDidLoad];
}
这是tableview的代码
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [alDescArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [alDescArray objectAtIndex:indexPath.row];
return cell;
}
请帮助谢谢

显然你的tableview的delegate / dataSource没有设置。
·H
YourClassName : ParentClass <UITableViewDelegate, UITableViewDataSource>
的.m
- (void)viewDidLoad
{
yourTableView.delegate = self;
yourTableView.dataSource = self;
NSArray *BusRoute = alightDesc;
int i;
int count = [BusRoute count];
for (i = 0; i < count; i++)
{
NSDictionary *dic = [BusRoute objectAtIndex: i];
NSDictionary *STEPS = [dic valueForKey:@"STEPS"];
alDescArray = [STEPS valueForKey:@"AlightDesc"];
}
[super viewDidLoad];
}
