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];
