获取iOS项目名称及版本号的方法（再开过程往往遇到一些问题，比如我遇到的问题是版本更新后需要清除以前的本地缓存，跳转登录页面重新登录，所以要获取app版本号存到本地，以后在appstore更新版本时，和本地版本号判断，不相等清除，相等进入）
NSString *executableFile = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleExecutableKey]; //获取项目名称
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey]; //获取项目版本号
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
// app名称
NSString *app_Name = [infoDictionary objectForKey:@"CFBundleDisplayName"];
// app版本
NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
// app build版本
NSString *app_build = [infoDictionary objectForKey:@"CFBundleVersion"];
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
CFShow(infoDictionary);
// app名称
NSString *app_Name = [infoDictionary objectForKey:@"CFBundleDisplayName"];
// app版本
NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
// app build版本
NSString *app_build = [infoDictionary objectForKey:@"CFBundleVersion"];
