獲取UILabel的numberOfLine

獲取UILabel的numberOfLine

    CGFloat textH = [self.label.text boundingRectWithSize:CGSizeMake(width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:15]} context:nil].size.height;
    CGFloat lineHeight = self.label.font.lineHeight;
    NSInteger lineCount = textH / lineHeight;
    NSLog(@"-----:%ld  %.f",lineCount,lineHeight);

 

若是但願UILabel的右面添加更多，比方說顯示3行，能夠給UILabel設置

self.label.numberOfLines = 3; 

在獲取UILabel實際的numberOfLine，若是大於，則顯示更多按鈕
