• IOS 自己定义UITableView


    依据不同须要,须要使用tableview的结构,可是里面每个cell,又须要自己的样式。所以学习了一下如何把自定义的cell加到tableview里面



    首先要自己创建一个类,继承UITableViewCell,然后新建一个空的xib文件,并在class属性设置为相应的类名







    代码部分:

    <pre name="code" class="objc">
    
    #import "SettingViewController.h"
    #import "SettingViewCell.h"
    @interface SettingViewController ()
    
    @end
    
    @implementation SettingViewController
    @synthesize listArray =_listArray;
    
    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
    {
        self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
        if (self) {
            // Custom initialization
        }
        return self;
    }
    
    - (void)viewDidLoad
    {
        [super viewDidLoad];
        // Do any additional setup after loading the view from its nib.
        NSArray *array = [NSArray arrayWithObjects: @"房间设置",@"灯光设置",@"窗帘设置",@"场景设置",@"空调设置",@"安防设置",@"网络设置",nil];
        _settingview.dataSource =self; //设置数据源方法
        _settingview.delegate =self;//设置代理方法
        self.listArray =array; //注意。因为内存管理问题。假设不正确self.listArray进行赋值,则_listArray会被清空。程序会崩溃
     
    }
    - (IBAction)backClicked:(id)sender {
        [self.navigationController popToRootViewControllerAnimated:YES];
    }
    //数据源方法
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {
            return [_listArray count];
    }
    
    //托付方法
    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        switch(indexPath.row)
        {
            case 0:
                break;
            default:
                break;
        }
    }
    // Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier:
    // Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)
    
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString * cellIdentifier =@"mycell";
        SettingViewCell  *cell =(SettingViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
        if(cell == nil)
        {
            NSArray *array =[[NSBundle mainBundle] loadNibNamed:@"SettingViewCell" owner:self options:nil];
            cell = [array objectAtIndex: 0];
            [cell setSelectionStyle:UITableViewCellSelectionStyleGray];
        }
        
        NSString *text = _listArray[indexPath.row];
     
        [[cell settingName] setText:text];
        return cell;
    }
    
    
    - (void)didReceiveMemoryWarning
    {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }
    
    - (void)dealloc {
        [_back release];
        [_settingview release];
        [super dealloc];
    }
    @end
