我正在关注Spotify SDK tutorial，并试图为我的应用程序创建一个RN模块。这是我的SpotifyModule.m代码：ReactNative iOS Spotify SDK
#import "SpotifyModule.h"
#import "React/RCTLog.h"
#import "React/RCTBridge.h"
@implementation SpotifyModule
RCT_EXPORT_MODULE()
+ (id)sharedManager {
static SpotifyModule *sharedManager = nil;
@synchronized(self) {
if (sharedManager == nil)
sharedManager = [[self alloc] init];
}
return sharedManager;
}
RCT_EXPORT_METHOD(authenticate:(RCTResponseSenderBlock)callback)
{
// Your implementation here
RCTLogInfo(@"authenticate");
self.auth = [SPTAuth defaultInstance];
// The client ID you got from the developer site
self.auth.clientID = @"8fff6cbb84d147e383060be62cec5dfa";
// The redirect URL as you entered it at the developer site
self.auth.redirectURL = [NSURL URLWithString:@"my-android-auth://callback"];
// Setting the `sessionUserDefaultsKey` enables SPTAuth to automatically store the session object for future use.
self.auth.sessionUserDefaultsKey = @"current session";
// Set the scopes you need the user to authorize. `SPTAuthStreamingScope` is required for playing audio.
self.auth.requestedScopes = @[SPTAuthPlaylistReadPrivateScope, SPTAuthUserReadPrivateScope];
//save the login callback
SpotifyModule *spotifyModule = (SpotifyModule *)[SpotifyModule sharedManager];
spotifyModule.loginCallback = callback;
//setup event dispatcher
spotifyModule.eventDispatcher = [[RCTEventDispatcher alloc] init];
[spotifyModule.eventDispatcher setValue:self.bridge forKey:@"bridge"];
// Start authenticating when the app is finished launching
dispatch_async(dispatch_get_main_queue(), ^{
[self startAuthenticationFlow];
});
}
- (void)startAuthenticationFlow
{
// Check if we could use the access token we already have
if ([self.auth.session isValid]) {
// Use it to log in
SpotifyModule *spotifyModule = (SpotifyModule *)[SpotifyModule sharedManager];
NSString *accessToken = self.auth.session.accessToken;
spotifyModule.loginCallback(@[accessToken]);
} else {
// Get the URL to the Spotify authorization portal
NSURL *authURL = [self.auth spotifyWebAuthenticationURL];
// Present in a SafariViewController
self.authViewController = [[SFSafariViewController alloc] initWithURL:authURL];
UIViewController *rootViewController = [UIApplication sharedApplication].delegate.window.rootViewController;
[rootViewController presentViewController:self.authViewController animated:YES completion:nil];
}
}
- (BOOL) application:(UIApplication *)app
openURL:(NSURL *)url
options:(NSDictionary *)options
{
// If the incoming url is what we expect we handle it
if ([self.auth canHandleURL:url]) {
// Close the authentication window
[self.authViewController.presentingViewController dismissViewControllerAnimated:YES completion:nil];
self.authViewController = nil;
// Parse the incoming url to a session object
[self.auth handleAuthCallbackWithTriggeredAuthURL:url callback:^(NSError *error, SPTSession *session) {
if (session) {
// Send auth token
SpotifyModule *spotifyModule = (SpotifyModule *)[SpotifyModule sharedManager];
NSString *accessToken = session.accessToken;
spotifyModule.loginCallback(@[accessToken]); }
}];
return YES;
}
return NO;
}
@end
我想从RN端使用它的方式，就是调用身份验证，与访问令牌的回调。我在Android上工作得很好。
Native.authenticate(function(token) {
store.dispatch(actions.loginSuccess(token));
});
在iOS上，与上面的代码，我得到本地的屏幕上，当单击确定，我得到以下错误：
从我最小的ObjectiveC理解SpotiFind[5475:29641] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[SpotifyModule application:openURL:sourceApplication:annotation:]: unrecognized selector sent to class 0x10cb406f8'
因此，它试图调用一个不同于本教程指导实施的方法。 关于如何使这项工作的任何建议？
如果它的任何有关，我对打造的iOS 10，并使用最新的Spotify iOS SDK
PS我实现了名称可能是针对某些copyrighting，其发展:)
嗨@Giannis，你有没有找到解决你的问题？我和你的情况完全相同。 – TimothePearce
没有使用教程代码，这是我用的： https://pastebin.com/yFKiqV2Z – Giannis
嘿@Giannis，感谢您的片段！我正在与TimothePearce合作并尝试使用您的代码。我是Objective-C中的绝对虚拟人（他也是如此），并且在使用Spotify登录后无法获取回调。 Webview打开后，我显示了Spotify授权页面，但是当我回到应用程序时，什么也没有发生。我正在测试一个简单的console.log（令牌），它不起作用。我从你的代码中看到，ObjC回调应该将东西记录在调试器中（如@“authenticate”），但它也不会发生。你知道为什么吗？ – rgehan
