A custom view component that lets the user easily present a progress view masked with an image containing an alpha channel (i.e. PNGs). The view's progress can be animated; foreground and background colors can be customized as well as the duration of the animation.
Usage is easy.
Add the dependency to your Podfile:
platform :ios
pod 'TWRProgressView'
...Run pod install to install the dependencies.
Next, import the header file wherever you want to use the picker:
#import "TWRProgressView.h"The progress view can be set up either via Interface Builder (XIB and Storyboards) by just setting TWRProgressView as the class of any UIView...
@property (weak, nonatomic) IBOutlet TWRProgressView *progressView;
...
UIImage *someImage = [UIImage imageNamed:@"image.png"];
[_progressView setMaskingImage:someImage];...or programmatically with a pretty sweet one-liner:
CGRect progressViewRect = CGRectMake(0, 0, 100, 100);
UIImage *someImage = [UIImage imageNamed:@"image.png"];
TWRProgressView *progressView = [TWRProgressView progressViewWithFrame:progressViewRect
andMaskingImage:someImage];
[self.view addSubview:progressView];TWRProgressView exposes the following methods that let the user customize color, progress and animation timing:
- (void)setProgress:(CGFloat)progress;
- (void)setProgress:(CGFloat)progress animated:(BOOL)animated;
- (void)setBackColor:(UIColor *)backColor;
- (void)setFrontColor:(UIColor *)frontColor;
- (void)setAnimationTime:(CGFloat)time;Take a look at this video:
