iOS实现类Siri曲线：Waver

Waver 是类似 Siri 的波纹曲线。

Requirements

Waver works on iOS 7.0 and later version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

• Foundation.framework
• UIKit.framework
• CoreGraphics.framework
• QuartzCore.framework

You will need LLVM 3.0 or later in order to build Waver.

Usage

Cocoapods

CocoaPods is the recommended way to add Waver to your project.

1. Add a pod entry for Waver to your Podfilepod 'Waver', '~> 0.2.0'
2. Install the pod(s) by runningpod install.
3. Include Waver wherever you need it with#import "Waver.h".

Or Copy the Waver folder to your project

Example

Waver * waver = [[Waver alloc] initWithFrame:CGRectMake(0, CGRectGetHeight(self.view.bounds)/2.0 - 50.0, CGRectGetWidth(self.view.bounds), 100.0)];    __weak Waver * weakWaver = waver;  waver.waverLevelCallback = ^() {        [self.recorder updateMeters];        CGFloat normalizedValue = pow (10, [self.recorder averagePowerForChannel:0] / 50);        weakWaver.level = normalizedValue;    };  [self.view addSubview:waver];
