? ?UISegmentedControl是一個多按鈕控制器，相當于好幾個button連在一起。

NSArray *segmentedArray = [[NSArrayalloc]initWithObjects:@"1",@"2",@"three",@"4",nil];

? ? //初始化UISegmentedControl

? ?UISegmentedControl *segmentedControl = [[UISegmentedControlalloc]initWithItems:segmentedArray];

segmentedControl.frame =CGRectMake(10.0,10.0, 300.0,50.0);

// 獲取索引

? ? [segmentedControlselectedSegmentIndex];

? ? //設置默認選擇項索引

? ? segmentedControl.selectedSegmentIndex =3;

? ? segmentedControl.tintColor = [UIColorredColor];

? ? //設置樣式

? ? segmentedControl.segmentedControlStyle =UISegmentedControlStyleBar;

? ? //設置在點擊后是否恢復原樣

? ? segmentedControl.momentary =YES;

? ? //設置指定索引選項不可選

? ? [segmentedControlsetEnabled:NOforSegmentAtIndex:4];

? ? //判斷指定索引選項是否可選

? ?BOOL enableFlag = [segmentedControl isEnabledForSegmentAtIndex:3];

? ?NSLog(@"%d",enableFlag);

? ? //添加響應事件

? ? [segmentedControl addTarget:selfaction:@selector(segmentSelect:)forControlEvents:UIControlEventValueChanged];

以上是segmentedControl常用的，下面介紹一些用的比較少的

//設置指定索引的題目

? ? [segmentedControlsetTitle:@"two"forSegmentAtIndex:1];

? ? //設置指定索引的圖片

? ? [segmentedControl setImage:[UIImageimageNamed:@"rating2.png"]forSegmentAtIndex:3];

? ? //在指定索引插入一個選項并設置圖片

? ? [segmentedControl insertSegmentWithImage:[UIImageimageNamed:@"rating1"]atIndex:2animated:NO];

? ? //在指定索引插入一個選項并設置題目

? ? [segmentedControl insertSegmentWithTitle:@"insert"atIndex:3animated:NO];

? ? //移除指定索引的選項

? ? [segmentedControl removeSegmentAtIndex:0animated:NO];

? ? //設置指定索引選項的寬度

? ? [segmentedControlsetWidth:80.0forSegmentAtIndex:2];

? ? //設置選項中圖片等的左上角的位置

? ? [segmentedControl setContentOffset:CGSizeMake(10.0,10.0)forSegmentAtIndex:1];

? ? //獲取指定索引選項的圖片imageForSegmentAtIndex：

? ?UIImageView *imageForSegmentAtIndex = [[UIImageViewalloc]initWithImage:[segmentedControlimageForSegmentAtIndex:1]];

? ? imageForSegmentAtIndex.frame =CGRectMake(60.0,100.0, 30.0,30.0);

?? ?

? ? //獲取指定索引選項的標題titleForSegmentAtIndex

? ?UILabel *titleForSegmentAtIndex = [[UILabelalloc]initWithFrame:CGRectMake(100.0,100.0, 30.0,30.0)];

? ? titleForSegmentAtIndex.text = [segmentedControltitleForSegmentAtIndex:0];

?? ?

? ? //獲取總選項數segmentedControl.numberOfSegments

? ?UILabel *numberOfSegments = [[UILabelalloc]initWithFrame:CGRectMake(140.0,100.0, 30.0,30.0)];

? ? numberOfSegments.text = [NSStringstringWithFormat:@"%d",segmentedControl.numberOfSegments];

?? ?

? ? //獲取指定索引選項的寬度widthForSegmentAtIndex：

? ?UILabel *widthForSegmentAtIndex = [[UILabelalloc]initWithFrame:CGRectMake(180.0,100.0, 70.0,30.0)];

? ? widthForSegmentAtIndex.text = [NSStringstringWithFormat:@"%.1f",[segmentedControlwidthForSegmentAtIndex:2]];

- (void)segmentSelect:(UISegmentedControl *)sender

{

? ? NSLog(@"index %i",sender.selectedSegmentIndex);

//可以通過判斷UISegmentedControl的按鈕index來實現自己的邏輯

}
