[英]Calling UITable View Delegate Method
I'm working with UITableView in UIViewController..I am using the following delegate methods..... 我正在使用UIViewController中的UITableView。我正在使用以下委托方法。
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
Once I load the view I find all delegates has been called..... But I need to call these methods in a button click..... 加载视图后,我发现所有代表都已被调用.....但是我需要在单击按钮时调用这些方法.....
I tried in this way.... 我尝试过这种方式。
[self tableView:table numberOfRowsInSection:rows];
[self tableView:table cellForRowAtIndexPath:path];
I find that these methods has been called,but nothing happened (code inside these delegates doesn't works).... I don't knw why??? 我发现这些方法已被调用,但是什么也没发生(这些委托中的代码不起作用)...。我不知道为什么??? Any suggestions??? 有什么建议么???
Write the code inside the button click function it will call all the delegates of the tableview 在按钮单击功能内编写代码,它将调用tableview的所有委托
[self.tableView reloadData];
or complete code to your solution is:- 或完整的代码到您的解决方案是:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
customCell *cell = [[customCell alloc]init];
if (cell == nil) {
cell = [[[customCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
NSArray *topLevelObjects=[[NSBundle mainBundle] loadNibNamed:@"customCell" owner:self options:nil];
cell = (customCell *)[topLevelObjects objectAtIndex:0];
int count=0;
for(id currentObject in topLevelObjects)
{
count++;
if([currentObject isKindOfClass:[customCell class]])
{
cell= (customCell *)currentObject;
UILabel *sName = (UILabel *)[cell.contentView viewWithTag:1];
//Checking the flag that is set in the btnClicked event
if (flag) {
sName.hidden=YES;
}
else{
sName.text = [arrayResult objectAtIndex:indexPath.row];
}
}
}
return cell;
[topLevelObjects release];
[cell release];
}
-(IBAction) btnClicked:(id) sender{
flag=YES;
[self.tableView reloadData];
}
Try this it will work.. 试试这个,它将起作用..
