• UISegment属性


    1.segmentedControlStyle

    设置segment的显示样式。

     1 typedef NS_ENUM(NSInteger, UISegmentedControlStyle) 
     2 {
     3 UISegmentedControlStylePlain,     // large plain 系统默认平板样式
     4 //segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
     5 
     6 UISegmentedControlStyleBordered,  // large bordered 黑边样式
     7 //segmentedControl.segmentedControlStyle = UISegmentedControlStyleBordered;
     8 
     9 UISegmentedControlStyleBar,       // small button/nav bar style. Tintable 条状样式
    10 //segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    11 
    12 UISegmentedControlStyleBezeled,   // DEPRECATED. Do not use this style. 这个类型不要使用,用了会报错喔。
    13 };
    系统默认平板样式:           黑边样式:                条状样式:

            

    2.tintColor 渐变颜色

    1 //Default tintColor is nil. Only used if style is UISegmentedControlStyleBar 默认空,只有使用UISegmentedControlStyleBar,才能设置渐变颜色。
    2 
    3 segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    4 segmentedControl.tintColor = [UIColor redColor];

    效果:

    3.momentary 设置在点击后是否恢复原样

    1 //默认为NO
    2 segmentedControl.momentary = No;

    点击之后效果:

    1 segmentedControl.momentary = YES;

    点击之后效果:

    4. numberOfSegments(只读)

    1 //获取总选项数
    2 segmentedControl.numberOfSegments 

    5. selectedSegmentIndex

    1 //用来设置选中项或者返回选中项。
    2 segmentedControl.selectedSegmentIndex = 2;//设置默认选择项索引
    3 segmentedControl.selectedSegmentIndex // 获取选中项

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

    1 [segmentedControl setTitle:@"two" forSegmentAtIndex:1];//设置指定索引的题目

    效果:

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

    1 [segmentedControl setImage:[UIImage imageNamed:@"lan.png"] forSegmentAtIndex:3];//设置指定索引的图片

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

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

    效果:

    9.-(void)insertSegmentWithImage:(UIImage *)image  atIndex:(NSUInteger)segment animated:(BOOL)animated;

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

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

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

    效果:

    11. - (void)removeAllSegments;

    1 //移除所有选项
    2 [segmentedControl removeAllSegments];

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

    1 //选项卡的宽度默认为0,此方法能够设置选项卡宽度。
    2 [segmentedControl setWidth:70.0 forSegmentAtIndex:2];//设置指定索引选项的宽度

    效果:

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

    1 [segmentedControl setContentOffset:CGSizeMake(10,0) forSegmentAtIndex:1];
    2 //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。

    效果:

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

    1 [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

    1 [segmentedControl addTarget:self  action:@selector(itemClick) forControlEvents:UIControlEventValueChanged];
