SVSegmentedControl (de-ARCed)
SVSegmentedControl 是一个可定制的 UIControl 类，模仿 UISegmentedControl 但看起来像 UISwitch。
安装
手动
注意：如果您的项目使用 ARC：您可能更好的使用原始的 SVSegmentedControl。
- 将
SVSegmentedControl.deARCed/SVSegmentedControl文件夹拖拽到您的项目中。 - 将 QuartzCore 框架添加到您的项目。
使用
(见 /Demo 中的示例 Xcode 项目)
以最简单的形式，这是创建 SVSegmentedControl 实例的方法
segmentedControl = [[[SVSegmentedControl alloc] initWithSectionTitles:[NSArray arrayWithObjects:@"Section 1", @"Section 2", nil]] autorelease];
segmentedControl.changeHandler = ^(NSUInteger newIndex) {
// respond to index change
};
[self.view addSubview:segmentedControl];您可以使用其 frame 或 center 属性来定位它
定制
SVSegmentedControl 可以通过以下属性进行定制
@property (nonatomic, strong) NSArray *sectionTitles;
@property (nonatomic, strong) NSArray *sectionImages;
@property (nonatomic, readwrite) BOOL animateToInitialSelection; // default is NO
@property (nonatomic, readwrite) BOOL crossFadeLabelsOnDrag; // default is NO
@property (nonatomic, readwrite) BOOL mustSlideToChange; // default is NO - To make the control difficult to accidentally change, force the user to slide it
@property (nonatomic, readwrite) CGFloat minimumOverlapToChange; // default is 0.66 - Only snap to a new segment if the thumb overlaps it by this fraction
@property (nonatomic, readwrite) UIEdgeInsets touchTargetMargins; // default is UIEdgeInsetsMake(0, 0, 0, 0) - Enlarge touch target of control
@property (nonatomic, strong) UIColor *backgroundTintColor; // default is [UIColor colorWithWhite:0.1 alpha:1]
@property (nonatomic, retain) UIImage *backgroundImage; // default is nil
@property (nonatomic, readwrite) CGFloat height; // default is 32.0
@property (nonatomic, readwrite) UIEdgeInsets thumbEdgeInset; // default is UIEdgeInsetsMake(2, 2, 3, 2)
@property (nonatomic, readwrite) UIEdgeInsets titleEdgeInsets; // default is UIEdgeInsetsMake(0, 10, 0, 10)
@property (nonatomic, readwrite) CGFloat cornerRadius; // default is 4.0
@property (nonatomic, retain) UIFont *font; // default is [UIFont boldSystemFontOfSize:15]
@property (nonatomic, retain) UIColor *textColor; // default is [UIColor grayColor];
@property (nonatomic, strong) UIColor *innerShadowColor; // default is [UIColor colorWithWhite:0 alpha:0.8]
@property (nonatomic, retain) UIColor *textShadowColor; // default is [UIColor blackColor]
@property (nonatomic, readwrite) CGSize textShadowOffset; // default is CGSizeMake(0, -1)它的滑块 (SVSegmentedThumb) 也可以进行定制
@property (nonatomic, retain) UIImage *backgroundImage; // default is nil;
@property (nonatomic, retain) UIImage *highlightedBackgroundImage; // default is nil;
@property (nonatomic, retain) UIColor *tintColor; // default is [UIColor grayColor]
@property (nonatomic, assign) UIColor *textColor; // default is [UIColor whiteColor]
@property (nonatomic, assign) UIColor *textShadowColor; // default is [UIColor blackColor]
@property (nonatomic, readwrite) CGSize textShadowOffset; // default is CGSizeMake(0, -1)
@property (nonatomic, readwrite) BOOL shouldCastShadow; // default is YES (NO when backgroundImage is set)
@property (nonatomic, assign) CGFloat gradientIntensity; // default is 0.15为了定制滑块的显示，您必须通过 SVSegmentedControl 的 thumb 属性设置属性。例如，设置滑块的 tintColor 使用以下方式完成
segmentedControl.thumb.tintColor = someColor;响应值变化
您可以使用块处理器来响应值变化
segmentedControl.changeHandler = ^(NSUInteger newIndex) {
// respond to index change
};如果您还没爱上块，您仍然可以使用经典 UIControl 方法
[mySegmentedControl addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];提供一个以分号结尾的动作方法，因此发送对象是可访问的
- (void)segmentedControlChangedValue:(SVSegmentedControl*)segmentedControl {
NSLog(@"segmentedControl did select index %i", segmentedControl.selectedIndex);
