私はiPhone開発の初心者で、これが私の最初の質問です。
UIScrollView に UITableView を表示していますが、データが静的ではなくサービスから取得されるため、tableView と scrollView の両方の高さを指定できませんでした。
tableViewのコンテンツ（高さ）に応じて動的に高さを設定するには、scrollViewが必要です。これを実行しましたが、最後のセルの完全なデータが表示されませんでした。
self.tableView=[[UITableView alloc] initWithFrame:CGRectMake(0,0,327,480) style:UITableViewStylePlain];
self.tableView.delegate=self;
self.tableView.dataSource=self;
self.tableView.scrollEnabled = NO;
[testscroll addSubview:self.tableView];
[self.tableView reloadData];
self.tableView.frame = CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.tableView.contentSize.height);
float ftbl = self.tableView.frame.origin.y + self.tableView.contentSize.height + 150;
scrollView.contentSize=CGSizeMake(320, ftbl);
scrollView.scrollEnabled=YES;
テーブルビューの高さを計算しています：
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [self tableView: self.tableView cellForRowAtIndexPath: indexPath];
NSString *city = lblcity.text;
UIFont *font = [UIFont fontWithName:@"Helvetica" size:14.0];
CGSize constraintSize = CGSizeMake(280.0f, MAXFLOAT);
CGSize bounds = [city sizeWithFont:font constrainedToSize:constraintSize lineBreakMode:NSLineBreakByWordWrapping];
NSString *state = lblstate.text;
UIFont *font1 = [UIFont fontWithName:@"Helvetica" size:14.0];
CGSize constraintSize1 = CGSizeMake(280.0f, MAXFLOAT);
CGSize bounds1 = [state sizeWithFont:font1 constrainedToSize:constraintSize1 lineBreakMode:NSLineBreakByWordWrapping];
NSString *name = lblname.text;
UIFont *font2 = [UIFont fontWithName:@"Helvetica" size:14.0];
CGSize constraintSize2 = CGSizeMake(280.0f, MAXFLOAT);
CGSize bounds2 = [name sizeWithFont:font2 constrainedToSize:constraintSize2 lineBreakMode:NSLineBreakByWordWrapping];
NSString *address = lbladdress.text;
UIFont *font3 = [UIFont fontWithName:@"Helvetica" size:14.0];
CGSize constraintSize3 = CGSizeMake(280.0f, MAXFLOAT);
CGSize bounds3 = [address sizeWithFont:font5 constrainedToSize:constraintSize3 lineBreakMode:NSLineBreakByWordWrapping];
return (CGFloat) cell.bounds.size.height + bounds.height+bounds1.height+bounds2.height+bounds3.height;
}
UItableviewの高さに応じてscrollViewの高さを増減するにはどうすればよいですか?
