Question

我有UITextField和Progress视图。我希望该用户在文本字段中输入值，并且在该时间内，进度视图应填充至100％且平滑动画，并且应在标签中显示进程完成百分比

我已为此编写了此代码，它显示了已填充进度视图的平滑动画，但未显示％进程完成。

这是我的代码：

#import "ViewController.h"

@interface ViewController ()
@property (weak, nonatomic) IBOutlet UILabel *lblProgres;

@property (weak, nonatomic) IBOutlet UITextField       *txtValue;
@property (weak, nonatomic) IBOutlet UIProgressView *progressBar;
- (IBAction)btnRestPressed:(id)sender;

- (IBAction)btnAction:(id)sender;
@end

@implementation ViewController

- (IBAction)btnRestPressed:(id)sender {

    [self.progressBar setProgress:0.0];
}

- (IBAction)btnAction:(id)sender {

       float val1 = 1/[self.txtValue.text floatValue];

//    [self.progressBar setProgress:0];
    NSTimer *timer =  [NSTimer timerWithTimeInterval:val1 target:self selector:@selector(startedProgress:)userInfo:nil repeats:YES];
    [timer fire];
    if(self.progressBar.progress != 1.0)
        [[NSRunLoop mainRunLoop] addTimer:timer forMode:NSDefaultRunLoopMode];



  }

                float i=0;;
                                if(self.progressBar.progress >= 0.0) {

                               //     for(i = 1; i <= 100*10; i++) {
                                        [self.progressBar setProgress:[self.progressBar progress] + 1 /val1  animated:YES] ;


                                        NSLog(@"%f",self.progressBar.progress);
                               //    }
                                    if(self.progressBar.progress == 1.0) {

                                        [timer invalidate];

                                    }

                }

            } completion:^(BOOL finished) {

添加

self.lblProgres.text =  [NSString stringWithFormat:@"%f %",self.progressBar.progress*100];

在

 [self.progressBar setProgress:[self.progressBar progress] + 1 /val1  animated:YES] ;

UITextField和进度条
