例如,下面是如何更新
numberOfSectionsInTableView:
,
tableView:numberOfRowsInSection:
,及
tableView:cellForRowAtIndexPath:
,但您至少需要更新
tableView:didSelectRowAtIndexPath:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// calculate the number of sections of non-data (might just be 1)
// calculate the number of sections for the data (you were already doing this, might just be 1)
// return the sum
return 1 + 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSInteger rowCount = 0;
switch (section) {
case 0:
// non-data section has 1 row/cell
rowCount = 1;
break;
case 1:
// data section uses an array
rowCount = [dataArray count];
break;
}
return rowCount;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *nonDataCellID = @"NonDataCell";
static NSString *dataCellID = @"DataCell";
UITableViewCell *cell;
int section = [indexPath indexAtPosition:0];
int row = [indexPath indexAtPosition:1];
switch (section) {
case 0:
// or you can just use standard cells here
cell = [tableView dequeueReusableCellWithIdentifier:nonDataCellID];
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:@"NonDataCell" owner:self options:NULL];
cell = nonDataCell; // nonDataCell is an IBOutlet to this custom cell
}
// configure non-data cell here (use tags)
UILabel *someLabel = (UILabel*)[cell viewWithTag:1];
someLabel.text = @"Non-data cell";
break;
case 1:
// or you can just use standard cells here
cell = [tableView dequeueReusableCellWithIdentifier:dataCellID];
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:@"dataCell" owner:self options:NULL];
cell = dataCell; // dataCell is an IBOutlet to this custom cell
}
// configure data call here (using "row")
UILabel *someDataLabel = (UILabel*)[cell viewWithTag:1];
someDataLabel.text = [[dataArray objectAtIndex:row] valueForKey:@"name"];
break;
}
return cell;
}
