UISegment属性

1.segmentedControlStyle

设置segment的显示样式。

typedefNS_ENUM(NSInteger,UISegmentedControlStyle) {

UISegmentedControlStylePlain,// large

plain系统默认平板样式

segmentedControl.segmentedControlStyle =UISegmentedControlStylePlain;

UISegmentedControlStyleBordered,// large

bordered黑边样式

segmentedControl.segmentedControlStyle =

UISegmentedControlStyleBordered;

UISegmentedControlStyleBar,// small button/nav bar style. Tintable条状样式

segmentedControl.segmentedControlStyle=UISegmentedControlStyleBar;

UISegmentedControlStyleBezeled,// DEPRECATED. Do not use this style.这个类型不要使用,用了会报错喔。

};

2.tintColor渐变颜色

Default tintColor is nil. Only used ifstyle is UISegmentedControlStyleBar

默认空，只有使用UISegmentedControlStyleBar，才能设置渐变颜色。

segmentedControl.segmentedControlStyle=UISegmentedControlStyleBar;

segmentedControl.tintColor= [UIColorredColor];

3.momentary设置在点击后是否恢复原样

默认为NO

segmentedControl.momentary=No;

segmentedControl.momentary=YES;

4. numberOfSegments(只读)

获取总选项数segmentedControl.numberOfSegments

5. selectedSegmentIndex

用来设置选中项或者返回选中项。

segmentedControl.selectedSegmentIndex =

2;//设置默认选择项索引

segmentedControl.selectedSegmentIndex //获取选中项

6.- (void)setTitle:(NSString*)title forSegmentAtIndex:(NSUInteger)segment;

[segmentedControl setTitle:@"two"

forSegmentAtIndex:1];//设置指定索引的题目

7.- (void)setImage:(UIImage *)imageforSegmentAtIndex:(NSUInteger)segment;

[segmentedControl setImage:[UIImage imageNamed:@"lan.png"]

forSegmentAtIndex:3];//设置指定索引的图片

8.-(void)insertSegmentWithTitle:(NSString*)titleatIndex:(NSUInteger)segment animated:(BOOL)animated;

[segmentedControlinsertSegmentWithTitle:@"add"atIndex:3animated:NO];//在指定索引插入一个选项并设置题目

9.-(void)insertSegmentWithImage:(UIImage*)imageatIndex:(NSUInteger)segmentanimated:(BOOL)animated;

[segmentedControlinsertSegmentWithImage:[UIImageimageNamed:@"mei.png"]atIndex:2animated:NO];//在指定索引插入一个选项并设置图片

10．- (void)removeSegmentAtIndex:(NSUInteger)segmentanimated:(BOOL)animated;

[segmentedControlremoveSegmentAtIndex:0animated:NO];//移除指定索引的选项

11. - (void)removeAllSegments;

//移除所有选项

//[segmentedControlremoveAllSegments];

12. - (void)setWidth:(CGFloat)widthforSegmentAtIndex:(NSUInteger)segment;// set to 0.0 width to autosize. default is 0.0

选项卡的宽度默认为0，此方法能够设置选项卡宽度。

[segmentedControlsetWidth:70.0forSegmentAtIndex:2];//设置指定索引选项的宽度

13. - (void)setContentOffset:(CGSize)offsetforSegmentAtIndex:(NSUInteger)segment;// adjustoffset of image or text inside the segment. default is (0,0)

[segmentedControlsetContentOffset:CGSizeMake(10,0)forSegmentAtIndex:1];

设置选项卡内部文字或者图片与默认位置的偏移量，默认位置在选项卡的中心。

14. - (void)setEnabled:(BOOL)enabledforSegmentAtIndex:(NSUInteger)segment;

[segmentedControl setEnabled:NO forSegmentAtIndex:4];//设置指定索引选项不可选

15.增加事件响应机制

监听的是这个事件：UIControlEventValueChanged，值改变事件

[segmentedControladdTarget:selfaction:@selector(itemClick)forControlEvents:UIControlEventValueChanged];
