tabbaritem的png無法顯示、是gray：2011年04月04日星期一

使用tabbarcontroller，需要更改tabbaritem上的image，一般都用.png檔，實作發現，許多.png檔無法顯示，呈現出來的是一片灰白-gray。

原因：.png檔的background必需為透明(transparent)。

解法：

找免費軟體GIMP2。

打開GIMP2，檔案/新增，寬度、高度各鍵入32，點進階選項左的+號，填上右的背景顏色改為透明，點確定。點工具箱的A，點剛新增的圖層，鍵入B，將B調整覆蓋前一圖層，點圖層/向下合併，現在有了一個32x32英文字B的透明icon.

點檔案/另存新檔，選folder，鍵入檔名(例如B1.)，點選擇檔案格式左之+號，選png檔，點儲存。再將B1.png存入Xcode project內。

這時回tabbarcontroller的.nib、例如MainWindow.nib，點MainWindow.nib，再點Tab Bar Controller icon，再雙點苿tabbaritem後，點Tools/Attribute inspector, 點Image右，選B1.png。tabbaritem的png正常顯示了。

問題：如何將原本background不透明的.png改為background透明？
