_signal = [[GradientColorSignal alloc] init];
[_signal setType: SignalTypeDefault];
[_signal setStartAngle: @(-M_PI/2)];
//[_signal setEndAngle: @(M_PI/2)];

[_signal animateToScale: 0.33 duration: 0.3 function:[CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseIn]];

Signal Type Searching:

#import "GradientColorSignal.h"

_signal = [[GradientColorSignal alloc] init];
[_signal setType: SignalTypeSearching];
[_signal setSearchingColor: [UIColor grayColor]];
[_signal setStartAlpha: 1.0];
[_signal setEndAlpha: 0.1];
[_signal setClockwise: YES];
