HZActivityIndicatorView

A highly customizable drop-in replacement for UIActivityIndicatorView

HZActivityIndicatorView has to be compiled with ARC, a branch with classic memory managment might be added soon.

Usage

HZActivityIndicatorView can be used just like UIActivityIndicatorView and supports the default UIKit styles for activity indicators.

HZActivityIndicatorView *activityIndicator = [[HZActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
[activityIndicator startAnimating];

Customization

A few extra properties allow you to further customize the activity indicator

// size is automatically calculated using finSize and indicatorRadius,
// so no need to set it.
HZActivityIndicatorView *activityIndicator = 
    [[HZActivityIndicatorView alloc] initWithFrame:CGRectMake(50, 50, 0, 0)];

// set the number of "fins" in our indicator
activityIndicator.steps = 8; 

// size of each fin
activityIndicator.finSize = CGSizeMake(17, 10);

// which corners are round
activityIndicator.roundedCoreners = UIRectCornerAllCorners;

// corner radius of fins
activityIndicator.cornerRadii = CGSizeMake(0, 0);

// radius of the inner circle
activityIndicator.indicatorRadius = 20;

// animation interval
activityIndicator.stepDuration = 0.1;

// indicator color
activityIndicator.color = [UIColor colorWithRed:85.0/255.0 green:0.0 blue:0.0 alpha:1.000];

// animation direction
activityIndicator.direction = HZActivityIndicatorDirectionCounterClockwise;

[activityIndicator startAnimating];
