Objective-C：以编程方式查看进度

Question

如何在Xcode项目中以高度50和圆角编程地创建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

我试图获得带有圆角的进度视图。

首先，您需要添加和导入

#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];

也

KAProgressLabel

循环进度视图

使用Bezir路径的进度视图

Answer 2

 UIProgressView *progressView = [[UIProgressView alloc] initWithProgressViewStyle:whateverStyle]
progressView.progress = 0.75f;

//设置高度和角

[[UIProgressView appearance] setFrame:CGRectMake(20, 100, 280, 50)];
[progressView.layer setCornerRadius:4];
 progressView.layer.masksToBounds = TRUE;
 progressView.clipsToBounds = TRUE;

[self.view addSubview: progressView]

Answer 3

您可以使用以下代码：

UIProgressView *progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
    progressView.progress = 0.75f;
    [progressView.layer setCornerRadius:10];
    progressView.layer.masksToBounds = TRUE;
   progressView.clipsToBounds = TRUE;
    CGAffineTransform transform = CGAffineTransformMakeScale(1.0f, 10.0f);
    progressView.transform = transform;

    [self.view addSubview: progressView];
