NSArray *segmentedArray = [[NSArray alloc]initWithObjects:@"1",@"2",@"3",nil];

UISegmentedControl *segmentedTemp = [[UISegmentedControl alloc]initWithItems:segmentedArray];

self.segmentedControl = segmentedTemp;

segmentedControl.frame = CGRectMake(10.0, 10.0, 300.0, 29.0);

2.常用属性及设置方法如下：

//设置指定索引的题目

[segmentedControl setTitle:@"1" forSegmentAtIndex:1];

//设置指定索引的图片

[segmentedControl setImage:[UIImage imageNamed:@"home.png"] forSegmentAtIndex:2];

//在指定索引插入一个选项并设置图片

[segmentedControl insertSegmentWithImage:[UIImage imageNamed:@"more.png"] atIndex:2 animated:NO];

//在指定索引插入一个选项并设置题目

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

//移除指定索引的选项

[segmentedControl removeSegmentAtIndex:0 animated:NO];

//设置指定索引选项的宽度

[segmentedControl setWidth:60.0 forSegmentAtIndex:2];

//设置选项中图片等的左上角的位置

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

//设置默认选择项索引

segmentedControl.selectedSegmentIndex = 2;

//分段控件的颜色，只有样式为UISegmentedControlStyleBar的时候才有效果

segmentedControl.tintColor = [UIColor redColor];

//设置样式

segmentedControl.segmentedControlStyle = UISegmentedControlStyleBordered;

//设置在点击后是否恢复原样

segmentedControl.momentary = NO;

//设置指定索引选项不可选

[segmentedControl setEnabled:NO forSegmentAtIndex:3];

//判断指定索引选项是否可选

BOOL enableFlag = [segmentedControl isEnabledForSegmentAtIndex:3];

NSLog(@"%d",enableFlag);

[segmentedControl addTarget:self
action:@selector(segmentAction:)
forControlEvents:UIControlEventValueChanged];
 
-(void)segmentAction:(UISegmentedControl *)Seg
{
NSInteger index = Seg.selectedSegmentIndex;
switch (index) {
case 0:
NSLog(@"0 clicked.");
break;
case 1:
NSLog(@"1 clicked.");
break;
case 2:
NSLog(@"2 clicked.");
break;
case 3:
NSLog(@"3 clicked.");
break;
case 4:
NSLog(@"4 clicked.");
break;
default:
break;
}
}
 
//获取指定索引选项的图片imageForSegmentAtIndex：
UIImageView *imageForSegmentAtIndex = [[UIImageView alloc]initWithImage:[segmentedControl imageForSegmentAtIndex:1]];
imageForSegmentAtIndex.frame = CGRectMake(60.0, 100.0, 30.0, 30.0);
 
//获取指定索引选项的标题titleForSegmentAtIndex
UILabel *titleForSegmentAtIndex = [[UILabel alloc]initWithFrame:CGRectMake(100.0, 100.0, 30.0, 30.0)];
titleForSegmentAtIndex.text = [segmentedControl titleForSegmentAtIndex:0];
 
//获取总选项数segmentedControl.numberOfSegments
UILabel *numberOfSegments = [[UILabel alloc]initWithFrame:CGRectMake(140.0, 100.0, 30.0, 30.0)];
numberOfSegments.text = [NSString stringWithFormat:@"%d",segmentedControl.numberOfSegments];
 
//获取指定索引选项的宽度widthForSegmentAtIndex：
UILabel *widthForSegmentAtIndex = [[UILabel alloc]initWithFrame:CGRectMake(180.0, 100.0, 70.0, 30.0)];
widthForSegmentAtIndex.text = [NSString stringWithFormat:@"%f",[segmentedControl widthForSegmentAtIndex:2]];
 
//cap insets用来指定哪些区域是固定不变的，未制定的区域则会repeat
 
UIImage *segmentSelected = [[UIImage imageNamed:@"bg_o.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(5, 5, 5, 5)];
 
UIImage *segmentUnselected = [[UIImage imageNamed:@"bg.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(5, 5, 5, 5)];
 
UIImage *segmentSelectedUnselected = [UIImage imageNamed:@"line.png"] ;
 
UIImage *segUnselectedSelected = [UIImage imageNamed:@"line.png"] ;
 
UIImage *segmentUnselectedUnselected = [UIImage imageNamed:@"line.png"];
 
//Segmente未选中背景
[[UISegmentedControl appearance] setBackgroundImage:segmentUnselected
forState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
 
//Segmente选中背景
[[UISegmentedControl appearance] setBackgroundImage:segmentSelected
forState:UIControlStateSelected
barMetrics:UIBarMetricsDefault];
 
//Segmente左右都未选中时的分割线
//BarMetrics表示navigation bar的状态，UIBarMetricsDefault 表示portrait状态（44pixel height），UIBarMetricsLandscapePhone 表示landscape状态（32pixel height）
 
[[UISegmentedControl appearance] setDividerImage:segmentUnselectedUnselected
forLeftSegmentState:UIControlStateNormal
rightSegmentState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
 
[[UISegmentedControl appearance] setDividerImage:segmentSelectedUnselected
forLeftSegmentState:UIControlStateSelected
rightSegmentState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
 
[[UISegmentedControl appearance] setDividerImage:segUnselectedSelected
forLeftSegmentState:UIControlStateNormal
rightSegmentState:UIControlStateSelected
barMetrics:UIBarMetricsDefault];
 
//字体
NSDictionary *textAttibutesUnSelected = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont systemFontOfSize:18],UITextAttributeFont,
[UIColor blackColor],UITextAttributeTextColor,
[UIColor whiteColor],UITextAttributeTextShadowColor,
[NSValue valueWithCGSize:CGSizeMake(1, 1)],UITextAttributeTextShadowOffset,nil];
 
NSDictionary *textAttibutesSelected = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont systemFontOfSize:18],UITextAttributeFont,
[UIColor whiteColor],UITextAttributeTextColor,
[UIColor whiteColor],UITextAttributeTextShadowColor,
[NSValue valueWithCGSize:CGSizeMake(0, 0)],UITextAttributeTextShadowOffset,nil];
 
[[UISegmentedControl appearance] setTitleTextAttributes:textAttibutesUnSelected
