UIProgressView进度条的基本使用

UIProgressView ＊progressView=[[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleDefault];
//修改UIProgressView控件的大小
CGAffineTransform transform = CGAffineTransformMakeScale(1.0f, 3.0f);
 progressView = transform;
 //设置layer的颜色和边框
 progressView.layer.cornerRadius = 3.0f;
 progressView.layer.borderColor = [UIColor colorWithString:@"#64b3a0"].CGColor;
 progressView.layer.borderWidth = 0.5f;
 progressView.layer.masksToBounds = YES;
 
//进度条的颜色
progressView.trackTintColor = [UIColor whiteColor];
progressView.progressTintColor=[UIColor colorWithString:@"#64b3a0"]
progressView.progress=0.9；(0.0-1.0);之间
 [self.contentView addSubview:progressView];
