IOS开发（20）之UIProgressView控件

1 前言
UIProgressView控件用来显示进度条描述某个任务的进度。

2 代码实例
ZYViewController.h：

[plain] view plaincopyprint?#import <UIKit/UIKit.h>

@inte易做图ce ZYViewController : UIViewController

@property(nonatomic,strong) UIProgressView *progressView;

@end

#import <UIKit/UIKit.h>

@inte易做图ce ZYViewController : UIViewController

@property(nonatomic,strong) UIProgressView *progressView;

@end
ZYViewController.m:

[plain]
@synthesize progressView;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor = [UIColor whiteColor];
    self.progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];//初始化条状进度条
    self.progressView.center = self.view.center;
    self.progressView.progress = 0.5f;//设置进度条进度为50%
    [self.view addSubview:self.progressView];
}

@synthesize progressView;

- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor = [UIColor whiteColor];
    self.progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];//初始化条状进度条
    self.progressView.center = self.view.center;
    self.progressView.progress = 0.5f;//设置进度条进度为50%
    [self.view addSubview:self.progressView];
}
运行结果：
