查看bundleId和info.plist文件内容

 /******** OC ********/
    // 提取infoplist
    NSDictionary * info = [NSBundle mainBundle].infoDictionary;
    
    // 提取bundleID
    NSString * bundleID = [NSBundle mainBundle].bundleIdentifier;

/******** C *********/
    CFDictionaryRef info = CFBundleGetInfoDictionary(CFBundleGetMainBundle());
    
    CFStringRef bundleId = CFBundleGetIdentifier(CFBundleGetMainBundle());

// 打印所有infoplist文件内容
        let info:[String:AnyObject] = NSBundle.mainBundle().infoDictionary!
        print(info)
        
        // 提取bundleID
        let bundleId = NSBundle.mainBundle().bundleIdentifier
        print(bundleId)

如下为新建的Xcode临时工程里面的infoPlist文件的东西

当然如果向infoplist文件中新添加一些新的配置，添加的配置同样能够打印出来
