UISegmentedControl 开发笔记

// typedef NS_ENUM(NSInteger, UISegmentedControlStyle) {

// UISegmentedControlStylePlain, // large plain

// UISegmentedControlStyleBordered, // large bordered

// UISegmentedControlStyleBar, // small button/nav bar style. tintable

// UISegmentedControlStyleBezeled, // DEPRECATED. Do not use this style.

// } NS_DEPRECATED_IOS(2_0, 7_0, "The segmentedControlStyle property no longer has any effect");

//在ios7 里UISegmentedControlStyle 这个属性不在有效果

NSArray * itemArray = [NSArray arrayWithObjects:@"祝福",@"吻别",@"傻瓜",nil];

segmentedControl = [[UISegmentedControl alloc]initWithItems:itemArray];

segmentedControl.frame =CGRectMake(100,100,180,40);

segmentedControl.selectedSegmentIndex = 0;//设置默认选择项索引

//是否显示选中状态默认no

segmentedControl.momentary =NO;

//控件渲染色

UIColor *segmentedControltintColor = [[UIColor alloc]initWithRed:0.1green:1.0blue:123.88alpha:1.0];

segmentedControl.tintColor = segmentedControltintColor;

//分段控件的宽度

[segmentedControl setWidth:100forSegmentAtIndex:0];

//读取设置分段控件的宽度默认为 0

CGFloat itemWidth = [segmentedControl widthForSegmentAtIndex:0];

//分段控件的响应事件

[segmentedControl addTarget:selfaction:@selector(segmengAction:)forControlEvents:UIControlEventEditingChanged];

// For segments whose width value is 0, setting this property to YES attempts to adjust segment widths based on their content widths. Default is NO.

segmentedControl.apportionsSegmentWidthsByContent =NO;

//插入一个item

[segmentedControlin sertSegmentWithTitle:@"背包"atIndex:3animated:YES];

//插入一个带图片的item

[segmentedControl insertSegmentWithImage:[UIImage imageNamed:@"itemImage.png"]atIndex:4animated:YES];

//设置一个图片的item

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

//读取一个item图片

UIImage *segmentedControlimageItem = [segmentedControl imageForSegmentAtIndex:2];

//调整图片或文本在分段控件上的偏移

CGSize textSize =CGSizeMake(1,5);

[segmentedControl setContentOffset:textSize forSegmentAtIndex:2];

//获取偏移量 默认0

CGSize textfloat = [segmentedControl contentOffsetForSegmentAtIndex:2];

//设置 item是否可以点击默认 yes

[segmentedControl setEnabled:NO forSegmentAtIndex:4];

// 读取item 是否可以点击

BOOL item4isbool = [segmentedControl isEnabledForSegmentAtIndex:4];

//删除一个item

[segmentedControl removeSegmentAtIndex:0animated:YES];

//删除说有item

// [segmentedControl removeAllSegments];

//设置Item标题

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

// 读取item 的标题

NSString *titleString = [segmentedControl titleForSegmentAtIndex:1];

// 获取item 的索引号

int itemNumebr =segmentedControl.selectedSegmentIndex;

NSLog(@"title =%@",titleString);

//在导航栏中间

// self.navigationItem.titleView = segmentedControl;

[self.view addSubview:segmentedControl];

-(void)segmentAction:(UISegmentedControl *)Seg{

NSInteger Index = Seg.selectedSegmentIndex;

NSLog(@"Index %i", Index);
