Usage

Style

Colors

self.myProgressLabel.fillColor = [UIColor blackColor];
self.myProgressLabel.trackColor = [UIColor redColor];
self.myProgressLabel.progressColor = [UIColor greenColor];

Widths

self.myProgressLabel.trackWidth = 2.0;         // Defaults to 5.0
self.myProgressLabel.progressWidth = 4;        // Defaults to 5.0
self.myProgressLabel.roundedCornersWidth = 10; // Defaults to 0

Start and end labels

A (very) small text can be display at the start and end of the progress arc, via 2 dedicated labels. You can style this label any way you want.

self.myProgressLabel.startLabel.text = @"S";
self.myProgressLabel.endLabel.text = @"E";

Arc

Progress

If you only want to show a progress, it's straightforward.

// Progress must be between 0 and 1
self.myProgressLabel.progress = 0.5;

Specific start/end degrees

- (void)setStartDegree:(CGFloat)startDegree;
- (void)setEndDegree:(CGFloat)endDegree;

User interaction

You can allow the user to interact with both startDegree and endDegree. By default, user interaction is disabled.

// Activate user interaction on both sides
self.myProgressLabel.isStartDegreeUserInteractive = YES;
self.myProgressLabel.isEndDegreeUserInteractive = YES;

Animations

You can animate startDegree, endDegree and progress.

- (void)setStartDegree:(CGFloat)startDegree
               timing:(TPPropertyAnimationTiming)timing
             duration:(CGFloat)duration
                delay:(CGFloat)delay;

- (void)setEndDegree:(CGFloat)endDegree
             timing:(TPPropertyAnimationTiming)timing
           duration:(CGFloat)duration
              delay:(CGFloat)delay;

- (void)setProgress:(CGFloat)progress
            timing:(TPPropertyAnimationTiming)timing
          duration:(CGFloat)duration
             delay:(CGFloat)delay;

It's possible to stop an already started animation.

- (void)stopAnimations;

You can also add some custom logic at the end of an animation using the labelAnimCompleteBlock block.

self.myProgressLabel.labelAnimCompleteBlock = ^(KAProgressLabel *label) {
    NSLog(@"Animation complete !");
};
