题记

在今天这个变化多端的世界，我们最大的危险不是外界的压力与竞争，而是我们内心的模式，这些模式决定我们看到些什么，感受到些什么，如何思考以及最终成为怎么样的人

代码实现

#import <UIKit/UIKit.h>@interface HWProgressView : UIView@property (nonatomic, assign) CGFloat progress;
//进度条颜色
@property(nonatomic,strong) UIColor *progerssColor;
//进度条背景颜色
@property(nonatomic,strong) UIColor *progerssBackgroundColor;
//进度条边框的颜色
@property(nonatomic,strong) UIColor *progerssStokeBackgroundColor;
//进度条边框的宽度
@property(nonatomic,assign) CGFloat progerStokeWidth;@end

#import "HWProgressView.h"#define KProgressPadding 1.0f
@interface HWProgressView ()@property (nonatomic, weak) UIView *tView;

}
-(void)setProgerssBackgroundColor:(UIColor *)progerssBackgroundColor{_progerssBackgroundColor = progerssBackgroundColor;_borderView.backgroundColor=progerssBackgroundColor;
}//更新进度
- (void)setProgress:(CGFloat)progress
{_progress = progress;CGFloat margin = self.progerStokeWidth + KProgressPadding;CGFloat maxWidth = self.bounds.size.width - margin * 2;CGFloat heigth = self.bounds.size.height - margin * 2;_tView.frame = CGRectMake(margin, margin, maxWidth * progress, heigth);

使用

    //进度条HWProgressView *progressView = [[HWProgressView alloc] initWithFrame:CGRectMake(30, 365, 150, 20)];//进度条边框宽度progressView.progerStokeWidth=1.0f;//进度条未加载背景progressView.progerssBackgroundColor=[UIColor lightGrayColor];//进度条已加载 颜色progressView.progerssColor=[UIColor blueColor];//背景边框颜色progressView.progerssStokeBackgroundColor=[UIColor grayColor];[self.view addSubview:progressView];self.progressView = progressView;

更新进度

self.progressView.progress += 0.01;
