由於某些原因，某些詳細信息標籤不會顯示。我已經調試過程序，並且已經檢查過，細節標籤文本是正常的，在這種情況下，它是一個距離。我剪切了文本標籤文本，因此它不會與細節標籤重疊。另外，我沒有得到一個距離沒有填充！消息在我的代碼中。這是截圖（看2個第4行）：DetailTextLabel不顯示在iPhone的某些行上TableView

我試着使用StyleSubtitle：它的工作原理。但我想，爲什麼StyleValue1不？
你可以發佈剩餘的'UITableViewDataSource'和'UITableViewDelegate'方法嗎？ – 2012-02-27 11:40:19
是的，完成了。看看上面的代碼。我幾乎猜到了這個問題。我認爲，substringToIndex不適用於大寫字母。 – wzbozon 2012-02-28 09:35:26
