UISegmentedControl(类似Android中的TabHost)

  //标题

    NSArray  *images=[NSArray arrayWithObjects:@"nihao",@"wohao",@"tahoa",@"helloworld", nil];

    UISegmentedControl *sc = [[UISegmentedControl alloc] initWithItems:images];

sc.segmentedControlStyle = UISegmentedControlStyleBezeled; //有四种样式可选择





sc.momentary = NO;//设置选中状态，默认是NO;



self.navigationItem.titleView = sc;

sc.frame = CGRectMake(60, 100, 200, 40);

sc.selectedSegmentIndex = 1;//默认选择一个

    sc.tintColor = [UIColor redColor];

    [sc addTarget:self action:@selector(change:) forControlEvents:UIControlEventValueChanged];

    [self.view  addSubview:sc];

    [sc release];



//事件方法

- (void)change:(UISegmentedControl *)sc

{

    //角标

    NSLog(@"sc : %d", sc.selectedSegmentIndex);

}
