如何在iphone中突出顯示UILabel的單詞

Question

我正在用UILabel With Timer加載歌詞。現在我想用不同的顏色突出顯示該標籤的每個單詞。我怎樣才能做到這一點 ？

我顯示的歌詞這樣

- (void)setCurrentAudioProgress:(NSTimeInterval)time duration:(NSTimeInterval)duration 
{ 
    float progress = time/duration; 
    long currentPlaybackTime = audioPlayer.currentTime; 
    long remainingTime = (duration-time); 

    int remainingHours = (remainingTime /3600); 

    int remainingMinutes = ((remainingTime /60 -remainingHours*60)); 

    int remainingSeconds = (remainingTime %60); 


    int currentHours = (currentPlaybackTime/3600); 

    int currentMinutes = ((currentPlaybackTime/60) - currentHours*60); 
    int currentSeconds = (currentPlaybackTime % 60); 

    currentTimeLabel.text = [NSString stringWithFormat:@"%i:%02d:%02d", currentHours, currentMinutes, currentSeconds]; 

    remainingTimeLabel.text = [NSString stringWithFormat:@"%i.%02d.%02d", remainingHours , remainingMinutes, remainingSeconds]; 

    [progressView setProgress:progress]; 

    for (int i = 0; i<[lyricsArray count]; i++) { 

     NSString *lyricsTime = [[lyricsArray objectAtIndex:i]valueForKey:@"startTime" ] ; 

     if ([currentTimeLabel.text isEqualToString:lyricsTime]) { 

      songLyricsLabel.text = [NSString stringWithFormat:@"%@",[[lyricsArray objectAtIndex:i]valueForKey:@"songLyrics" ]];   
     }    
    }   
}

Answer 2

您可以使用下面你只要要突出顯示標籤文字，然後爲相應標籤添加以下行：

 label.highlighted = YES; 
label.highlightedTextColor = [UIColor blueColor]; 

對於不同的顏色，你可以添加一個數組的顏色名稱，並隨機選擇....
