UIProgressView進度條的基本使用 UIProgressView *progressView=[[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleDefault]; //修改UIProgressView控件的大小 CGAffineTransform transform = CGAffineTransformMakeScale(1.0f, 3.0f); progressView = transform; //設置layer的顏色和邊框 progressView.layer.cornerRadius = 3.0f; progressView.layer.borderColor = [UIColor colorWithString:@"#64b3a0"].CGColor; progressView.layer.borderWidth = 0.5f; progressView.layer.masksToBounds = YES; //進度條的顏色 progressView.trackTintColor = [UIColor whiteColor]; progressView.progressTintColor=[UIColor colorWithString:@"#64b3a0"] progressView.progress=0.9;(0.0-1.0);之間 [self.contentView addSubview:progressView];
