Marquee

Let's start with the original idea. When I first used the horse-running light function, I also found some SDKs, but I couldn't find one that fits my needs very well. The main problem is the problem after the gesture sliding (gesture sliding push/pop || front-back switching and so on when the horse-running light fails). At present, the level of support is &&up (forward &&reverse).To) scroll, solve push/pop &&foreground and background switching &&gesture sliding &&unexpected interruption, etc., I hope this SDK can help children with shoes that I have the same needs.

First, let's see if it fits your scene.

Function Description

1. Horizontal & Up (Forward & Reverse)

2. Lightweight Running Horselight

3. Front/Background Switch Reload

4. Get a running light status at any time

5. push/pop || Background and front switching || Auto scroll when gesture returns
   

How to use

1. Horizontal: Horizontal to left running lights

A. Simple integration: when used as a normal label, a single scroll time can be customized when initializing the method

/** Initialization
 *  duration: Single scroll time
 */
- (instancetype)initWithFrame:(CGRect)frame withSingleScrollDuration:(NSTimeInterval)duration;

b. State Freedom Settings: simply pass in the appropriate MarqueeState_H enumeration value by

/** Set up the state of the running light
 *  marqueeState: Horselight status (enumeration)
 *  Note: "Turn on the running light" in viewDidAppear and "Turn off the running light" in viewWillDisappear
 */
- (void)marqueeOfSettingWithState:(MarqueeState_H)marqueeState;

• Note: Detailed methods are available in demo, so you can use them when integrating. Also, note the functions used to place the Running Horselight method on/off.

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    
    // Turn on the running light
    [_marquee marqueeOfSettingWithState:MarqueeStart];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    
    // Turn off the running light
    [_marquee marqueeOfSettingWithState:MarqueeShutDown];
}

2. Up and down: Up and down (forward &reverse) rolling horselight

a. Simple integration: after normal initialization, the data source array passed in scrolling text is sufficient

b. State Freedom Settings: simply pass in the appropriate MarqueeState_V enumeration value by

/** Set up the state of the running light
 *  marqueeState: Horselight status (enumeration)
 */
- (void)marqueeOfSettingWithState:(MarqueeState_V)marqueeState;

c. Real-time callback: The current display text position in the data source array can be obtained in real time using the index attribute and scrollWithCallbackBlock method

/** Index of currently displayed text in data source array_Read-only */
@property (nonatomic, assign) NSInteger index;

/** Block for each rollback */
- (void)scrollWithCallbackBlock:(verticalMarqueeBlock)block;

d. Personalization settings: Personalized settings can be made through the following attributes

/** Whether to scroll counterclockwise (default:NO)
 *  Clockwise: Bottom==>Top
 *  Counterclockwise: Top==>Bottom
 */
@property (nonatomic, assign) BOOL isCounterclockwise;

/** Single scroll time
 *  default: 0.5f
 */
@property (nonatomic, assign) CGFloat scrollDuration;
/** Scroll Delay
 *  default: 2.5f
 */
@property (nonatomic, assign) CGFloat scrollDelay;

/** Color of scrolling text
 *  default: [UIColor blackColor]
 */
@property (nonatomic, strong) UIColor *verticalTextColor;
/** Font for scrolling text
 *  default: [UIFont systemFontOfSize:14]
 */
@property (nonatomic, strong) UIFont *verticalTextFont;
/** Display text alignment
 *  default: NSTextAlignmentLeft
 */
@property (nonatomic, assign) NSTextAlignment verticalTextAlignment;
/** Number of lines to display text
 *  default: 2(Note the setting of frame.width)
 */
@property (nonatomic, assign) NSInteger verticalNumberOfLines;
