使用目标→构建设置→产品名称。

在Xcode 4中，在目标的“Build Settings”标签下搜索“Product Name”。

选择项目导航器→选择目标→标识→显示名称→名称。

按照以下四个步骤维护序列号。在第四步中给出你想要的名字。

如果您需要在iPhone主屏幕上更改应用程序的名称，则需要在Target配置中进行，而不是在项目配置中进行。

Expand the Targets group in Xcode, and then single-click the item under that. It should share the name of your project, which is also the default name of the application that gets generated. Press Command + I to bring up the Info window, and then navigate to the Build tag. Set the Configuration drop-down to read All Configurations. Look for a setting called Product Name under the Packaging heading. Change that value to the name you want for your compiled applications and, in the immortal words of Bugs Bunny: Voilà! Do a clean and a build. Your application will take on the new name.

在目标→构建设置→产品名称字段中，您可以在这里编辑该字段。
