在此之前在 AppDelegate.m 中设置导航才可以完成效果
```
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//添加导航控制器
self.window.rootViewController = [[UINavigationController alloc]initWithRootViewController:[ViewController new]];
return YES;
}
```
// 这个我们的ViewController 在这里实现主要功能
#import "ViewController.h"
@interface ViewController ()<UITableViewDelegate,UITableViewDataSource>
{
UITableView * table;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"小优";
self.view.backgroundColor = [UIColor grayColor];
NSArray *array = [NSArray arrayWithObjects:@"唐装",@"男装",@"php",@"金溪",@"java",@"e语言", nil];
//初始化UISegmentedControl
UISegmentedControl *segment = [[UISegmentedControl alloc]initWithItems:array];
segment.tintColor = [UIColor whiteColor];
//设置frame
segment.frame = CGRectMake(0, 65, 340, 30);
//添加到视图
[self.view addSubview:segment];
UIButton * but = [[UIButton alloc]initWithFrame:CGRectMake(340, 65, 60, 30)];
[but setTitle:@"+" forState:UIControlStateNormal];
but.backgroundColor = [UIColor whiteColor];
[but addTarget:self action:@selector(dianji:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:but];
}
-(void)dianji:(UIButton *)btn
{
UIView * vieww = [[UIView alloc]initWithFrame:CGRectMake(260, 100, 60, 150)];
vieww.backgroundColor = [UIColor whiteColor];
[self.view addSubview:vieww];
table =[[UITableView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 150) style:UITableViewStyleGrouped];
table.delegate = self;
table.dataSource = self;
[vieww addSubview:table];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
return 3;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
static NSString * cellID = @"cell";
UITableViewCell * cell =[table dequeueReusableCellWithIdentifier:cellID];
if (!cell)
{
cell =[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
if (indexPath.row == 0)
{
cell.textLabel.text = @"添加";
}
if (indexPath.row == 1)
{
cell.textLabel.text = @"确认";
}
if (indexPath.row == 2)
{
cell.textLabel.text = @"关闭";
}
return cell;
}
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section

//弹出提示框；

}
}
