我刚刚升级到本机的最新版本(31),我的应用程序正在运行,不再工作了。每次我从获取中获得网络请求失败错误。
AppDelegate.m已更改,并且没有要更改的localhost或127.0.0.1。
它放在别的地方吗?
AppDelegate.m:
#import "AppDelegate.h"
#import "RCTBundleURLProvider.h"
#import "RCTRootView.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSURL *jsCodeLocation;
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName:@"OpenCampus"
initialProperties:nil
launchOptions:launchOptions];
rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
UIViewController *rootViewController = [UIViewController new];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;
}
@end
或者我应该更改RCTWebSocketExecutor.m?
if (!_url) {
NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults];
NSInteger port = [standardDefaults integerForKey:@"websocket-executor-port"] ?: 8081;
NSString *host = [[_bridge bundleURL] host];
if (!host) {
host = @"localhost";
}
NSString *URLString = [NSString stringWithFormat:@"http://%@:%zd/debugger-proxy?role=client", host, port];
_url = [RCTConvert NSURL:URLString];
}
_jsQueue = dispatch_queue_create("com.facebook.react.WebSocketExecutor", DISPATCH_QUEUE_SERIAL);
_socket = [[RCTSRWebSocket alloc] initWithURL:_url];
_socket.delegate = self;
_callbacks = [NSMutableDictionary new];
_injectedObjects = [NSMutableDictionary new];
[_socket setDelegateDispatchQueue:_jsQueue];
NSURL *startDevToolsURL = [NSURL URLWithString:@"/launch-js-devtools" relativeToURL:_url];
[NSURLConnection connectionWithRequest:[NSURLRequest requestWithURL:startDevToolsURL] delegate:nil];
if (![self connectToProxy]) {
RCTLogError(@"Connection to %@ timed out. Are you running node proxy? If "
"you are running on the device, check if you have the right IP "
"address in `RCTWebSocketExecutor.m`.", _url);
[self invalidate];
return;
}
答案 0 :(得分:0)
我找到了解决方案。 "允许任意负载"以某种方式从info.plist中删除。它应该被添加到info.plist中,值应为" YES"否则应用程序无法访问互联网。
