我想在UIView的子类上面添加一个广告单元RCTRootView.这将RCTRootView下降约50px.这是我目前的尝试.
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName:@"test"
launchOptions:launchOptions];
CGRect frame = rootView.frame;
frame.size.height -= 50;
rootView.frame = frame;
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.autoresizesSubviews = YES;
UIViewController *rootViewController = [[UIViewController alloc] init];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;

这是一个React Native项目,所以使用了StoryBoard.如何调整rootView的大小?
如何在UIView(广告单元)上方的UIWindow中实例化和附加viewController?

我试图使用RSpec 3来创建一个外部请求某些JSON的方法.我之前将它放在spec_helper.rb文件中,但是现在我重构并将方法移动到它自己的类中,不再存根作品.
RSpec.configure do |config|
config.before do
allow(Module::Klass).to receive(:request_url) do
JSON.parse(File.read(File.expand_path('spec/fixtures/example_data.json')))
end
end

这个班看起来像这样
module Module
class Klass
# public methods calling `request_url`

def request_url(url, header = {})
request = HTTPI::Request.new
request.url = url
request.headers = header
JSON.parse(HTTPI.get(request).body)

尽管保持spec_helper.rb相同并试图将存根放在实际规范之前,但仍在进行外部请求.
