版本 1.0

CSColorizedProgressView 是一个进度视图，可以将灰度图像转换为全色图像。它的外观如下：

基本用法

UIImage *image = [UIImage imageNamed:@"paris.png"]; // full-color image
CSColorizedProgressView *colorizedProgressView = [[[CSColorizedProgressView alloc] initWithImage:image] autorelease];
[self.view addSubview:colorizedProgressView];

[colorizedProgressView setProgress:0.75 animated:YES];

CSColorizedProgressView 还支持动画的完成块。这在进度达到 1.0 时特别有用，但您的应用程序 UI 应该在进度条视觉上完成之前不应响应。

colorizedProgressView.completionBlock = ^(CGFloat completedProgress) {
    if (completedProgress == 1.0) {
        NSLog(@"Progress completed!");
    }
};

设置说明

1. 将 CSColorizedProgressView.h 和 CSColorizedProgressView.m 添加到您的项目中。
2. 如果您使用 ARC，需要将 -fno-objc-arc 编译器标志添加到 CSColorizedProgressView.m。
