iOS 封装的一个简单的进度条

自己封装的一个简单的进度条，背景是图片，代码如下：

.h里边的代码

#import 

@interface ProgressImageView : UIView
/**
 进度值
 */
@property (nonatomic,assign)NSInteger progressValue;

/**
 进度条的颜色
 */
@property (nonatomic,strong) UIColor *progressColor;

/**
 进度条的背景图片
 */
@property (nonatomic,strong)UIImageView *bottomImageView;

//显示进度的视图（改变x的值）
@property (nonatomic,strong)UIView *fillView;

-(void)setProgressValue:(NSInteger)progressValue AndIndex:(NSInteger)progress;

.m里边的代码

#import "ProgressImageView.h"

@interface ProgressImageView()
{
    CGFloat fillViewWidth;
    CGFloat lineViewLeft;
}
@end
@implementation ProgressImageView

- (instancetype)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        self.backgroundColor = [UIColor clearColor];
        
        [self buildUI];
        
    }
    return self;
}

- (void)buildUI{

    _bottomImageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 2, self.width, self.height-4)];
    _bottomImageView.layer.cornerRadius = 3;
    _bottomImageView.layer.masksToBounds = YES;
    _bottomImageView.clipsToBounds = YES;
    [self addSubview:_bottomImageView];
    
    _fillView = [[UIView alloc]initWithFrame:CGRectMake(0-_bottomImageView.width, 0, _bottomImageView.width, _bottomImageView.height)];
    _fillView.layer.cornerRadius = 3;
    [_bottomImageView addSubview:_fillView];
    
}

-(void)setProgressValue:(NSInteger)progressValue AndIndex:(NSInteger)progress{
    _progressValue = progressValue;
    CGFloat X = [self getProgress:progress AndValue:progressValue];
//    fillViewWidth = [[[NSUserDefaults standardUserDefaults] objectForKey:@"fillViewWidth"] floatValue];
//        NSLog(@"width:%f",fillViewWidth);
//    if (fillViewWidth > 0) {
//        _fillView.left = X-_bottomImageView.width;
//        
//    }else{
//    
//    [UIView animateWithDuration:1 animations:^{
        if (progressValue == 0) {
            _fillView.hidden = YES;
        }else{
     _fillView.hidden = NO;
     _fillView.left = X-_bottomImageView.width;
     fillViewWidth = X;
        
      }
//    }];
//        [[NSUserDefaults standardUserDefaults] setObject:@(fillViewWidth) forKey:@"fillViewWidth"];
//    }
}
//进度条的颜色
- (void)setProgressColor:(UIColor *)progressColor{

    _progressColor = progressColor;
    _fillView.backgroundColor = progressColor;
}
//得到视图距离左边的位置
- (CGFloat)getProgress:(NSInteger)progress AndValue:(NSInteger)value{
    
   CGFloat X = (_bottomImageView.width/progress)*value;
    return X;
}

调用的时候：

 _progressView = [[ProgressImageView alloc]initWithFrame:CGRectMake(_dateLabel.left, _dateLabel.bottom+5, self.moreData.left-_leftImageView.right-10, _dateLabel.height+4)];
    [bgView addSubview:_progressView];
[ _progressView setProgressValue:当前进度值 AndIndex:进度条的最大进度值];
