objective - c

NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];

斯威夫特1.2

let bundleIdentifier = NSBundle.mainBundle().bundleIdentifier

斯威夫特3.0

let bundleIdentifier = Bundle.main.bundleIdentifier

Xamarin.iOS

var bundleIdentifier = NSBundle.MainBundle.BundleIdentifier

您可能需要使用Core Foundation方法来获取值。ARC示例如下:

NSString *value = (__bridge_transfer NSString *)CFDictionaryGetValue(CFBundleGetInfoDictionary(CFBundleGetMainBundle()),
                                                                     (const void *)(@"CFBundleIdentifier"));

在Swift 3.0中以编程方式获取bundle标识符:

斯威夫特3.0

let bundle = Bundle.main.bundleIdentifier

objective - c

NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];

斯威夫特1.2

let bundleIdentifier = NSBundle.mainBundle().bundleIdentifier

斯威夫特3.0

let bundleIdentifier = Bundle.main.bundleIdentifier

Xamarin.iOS

var bundleIdentifier = NSBundle.MainBundle.BundleIdentifier

如果你试图通过编程方式获取它，你可以使用下面的代码行:

objective - c:

NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];

Swift 3.0:

let bundleIdentifier =  Bundle.main.bundleIdentifier

它将工作在iOS和Mac应用程序。

[[NSBundle mainBundle] bundleIdentifier];
