以编程方式创建searchview ios

Question

我目前正在尝试以编程方式在带有tableview和searchbar的ios中创建一个searchview。 tableview的工作方式和预期的一样，但是搜索栏在屏幕左侧，只是它最后一个可见的像素。请告诉我我错在哪里。

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view from its nib. 

    //init array item for table view 
    self.timeZoneNames = [NSMutableArray array]; 
    for(int i = 0; i < 100; i++) 
    { 
     [self.timeZoneNames addObject:[NSString stringWithFormat:@"a %d", i]]; 
    } 

    //init rectangel that store table view's frame 
    UIScreen *mainScreen; 
    CGRect rect = CGRectMake(0, 44, [mainScreen applicationFrame].size.width,[mainScreen applicationFrame].size.height); 

    //init search bar 
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, [mainScreen applicationFrame].size.width, 44)]; 

    //init search controller that handle search bar 
    //UISearchDisplayController *searchController = [[UISearchDisplayController alloc] initWithSearchBar:search contentsController:self]; 
    //searchController.delegate = self; 
    //searchController.searchResultsDataSource = self; 

    //UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [mainScreen applicationFrame].size.width, 44)]; 
    //[view addSubview:search]; 

    //init table view, add search bar on top of table view and reload data 
    UITableView *table = [[UITableView alloc] initWithFrame:rect style:UITableViewStylePlain]; 
    table.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;  
    table.dataSource = self; 
    table.delegate = self; 
    //table.tableHeaderView = search; 
    [table reloadData]; 

    //set table view to be this controller's view 
    //self.view = table; 
    self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [mainScreen applicationFrame].size.width, [mainScreen applicationFrame].size.height)]; 

    self.view.backgroundColor = [UIColor blackColor]; 
    [self.view addSubview:table]; 
    [self.view addSubview:search]; 
}

可以使用self.view.bounds代替[mainScreen applicationFrame]。而且你不必为self.view再次分配内存。您可以删除该部分。
