Swift - 给表格的单元格UITableViewCell添加图片，详细文本标签

表格UITableView中，每一单元格都是一个UITableViewCell。其支持简单的自定义，比如在单元格的内部，添加图片和详细文本标签。

注意UITableViewCell的style：

（1） UITableViewCellStyle.Default：默认的，只有一个常规内容标签和一个可选的UIImageView

（2） UITableViewCellStyle.Value1：内容标签在左，详细标签在右，右边是蓝色或灰色的文本

（3） UITableViewCellStyle.Value2：同Value1位置相同，左边是蓝色文本

（4） UITableViewCellStyle.Subtitle：标签上下放置

效果图如下：

代码如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136
