ios - 在标签中显示百分比
<p><p>我使用代码来显示从 1% 到 100% 的文件下载进度。 </p>
<pre><code>if( downloadTask == _downloadTask26){
_progress26 = [ floatValue];
_total26 = [ floatValue];
}
if( downloadTask == _downloadTask27){
_progress27 = [ floatValue];
_total27 = [ floatValue];
}
float progress = _progress26 + _progress27;
float total = _total26 + _total27;
NSString *percentage = ;
(NSLog (percentage, @"%.f%%"));
if (!_label3) {
_label3 = [ initWithFrame:CGRectMake(200.43, 158.84, 42, 19)];
_label3.numberOfLines = 1;
_label3.baselineAdjustment = UIBaselineAdjustmentAlignBaselines;
_label3.adjustsFontSizeToFitWidth = YES;
_label3.minimumScaleFactor = 10.0f/12.0f;
_label3.clipsToBounds = YES;
_label3.backgroundColor = ;
_label3.textColor = ;
_label3.textAlignment = NSTextAlignmentCenter;
;
}
}
_label3.text = percentage;
if () {
}
</code></pre>
<p>但文件下载时，百分比不按升序显示。百分比以不同的顺序显示，如下面的视频所示。我该如何解决？</p>

<p><p>可能是由于下载任务条件检查它正在下载Task26或27将日志放在这两个条件中并检查下载和总大小。总任务可能会发生变化。 </p></p>
