ios - Objective-C:以编程方式查看进度

Question

如何在我的 Xcode 项目中以编程方式创建高度为 50 和圆角的 progressView？

如果我使用这段代码

CGAffineTransform transform = CGAffineTransformMakeScale(1.0f, 3.0f);  
progressView.transform = transform;

圆角消失

Answer 1

我尝试获取带有圆角的进度 View 。我明白了。

首先你需要添加和导入

#import <QuartzCore/QuartzCore.h>

然后

UIProgressView *progressView;
progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault];
progressView.progressTintColor = [UIColor colorWithRed:187.0/255 green:160.0/255 blue:209.0/255 alpha:1.0];
[[progressView layer]setFrame:CGRectMake(20, 50, 200, 200)];
[[progressView layer]setBorderColor:[UIColor redColor].CGColor];
progressView.trackTintColor = [UIColor clearColor];
[progressView setProgress:(float)(50/100) animated:YES];  ///15

[[progressView layer]setCornerRadius:progressView.frame.size.width / 2];
[[progressView layer]setBorderWidth:3];
[[progressView layer]setMasksToBounds:TRUE];
progressView.clipsToBounds = YES;

[self.view addSubview:progressView];
