ios - 如何显示界面生成器中定义的自定义单元格？

Question

我正在尝试嵌入自定义设计的 TableView 单元格(在界面生成器中)。对于初学者，我尝试在其自己的部分中添加一些文本字段。我能够显示定制设计的表格 View ，但是我做了一些不正确的事情，因为它看起来一团糟。也不太清楚如何添加其他部分。有人可以引导我走向正确的方向吗？我尝试了以下操作:http://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html#//apple_ref/doc/uid/TP40007451-CH7-SW20

但是有点迷失了。

它是这样的:

这是我在界面生成器中的设置:

这是我的代码:

头文件:

#import <UIKit/UIKit.h>

@interface SearchTableViewController : UITableViewController
{

}
@property (nonatomic, retain) IBOutlet UITableViewCell *priceRanceCell;
@end

实现:

#import "SearchTableViewController.h"


@interface SearchTableViewController ()

@end

@implementation SearchTableViewController
@synthesize priceRanceCell=_priceRanceCell;




- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = NSLocalizedString(@"Some Search", @"Some Search");
        self.tabBarItem.image = [UIImage imageNamed:@"search"];
    }
    return self;
}




- (void)viewDidLoad
{
    [super viewDidLoad];

    // Uncomment the following line to preserve selection between presentations.
    // self.clearsSelectionOnViewWillAppear = NO;

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

    // Return the number of sections.
    return 1;

    // Return the number of rows in the section.
    return 1;
}

    static NSString *CellIdentifier = @"SearchViewCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    // Configure the cell...

    switch (section) {
        case 0: // First cell in section 1


            return self.priceRanceCell;


            break;
        default:
            // Do something else here if a cell other than 1,2,3 or 4 is requested

            return cell;

            break;
    }








    return cell;
}

您需要实现heightForRowAtIndexPath:。另请注意，当您使用 dequeueReusableCellWithIdentifier: 时，结果可能为零，在这种情况下您需要创建一个单元。你应该修改你的逻辑，这样你就不会尝试它的第 0 部分。
