問題描述
首次在項(xiàng)目中集成weex的SDK（sdk版本是0.8.0市埋，Xcode 8），但是出現(xiàn)一些問題秉撇，
1. sdk放在podfile同級(jí)出現(xiàn)各種編譯不過
這個(gè)問題沒有截圖灵迫，主要是由于 Test里面的代碼，會(huì)有很多非arc的代碼蚕愤，后來我仿照playground的格式答恶，將sdk代碼放到項(xiàng)目根目錄的外面，可以順利解決編譯不過的問題
2. js文件加載不出來
當(dāng)我集成好了sdk萍诱，做好初始化悬嗓，去實(shí)例化一個(gè)_instance，去加載一個(gè)已經(jīng)編譯好的js文件時(shí)裕坊，出現(xiàn)以下錯(cuò)誤<Weex>[info]WXBridgeContext.m:292, No send queue for instance:1, may it has been destroyed so method:fireEvent is ignored [;并且所有的渲染工作都沒有做
我將同樣的js文件放到playground中包竹，就可以順利的渲染成功，一直都不明白該如何解決籍凝，找到最近一次打印的代碼周瞎，
- (void)executeJsMethod:(WXBridgeMethod *)method
{
WXAssertBridgeThread();
if (!method.instance) {
WXLogError(@"Instance doesn't exist!");
return;
}
NSMutableArray *sendQueue = self.sendQueue[method.instance];
if (!sendQueue) {
WXLogInfo(@"No send queue for instance:%@, may it has been destroyed so method:%@ is ignored", method.instance, method.method);
return;
}
[sendQueue addObject:method];
[self performSelector:@selector(_sendQueueLoop) withObject:nil];
}
該問題還未解決，解決后來更新答案
更新
對(duì)比了一下饵蒂，playground和自己項(xiàng)目的代碼流程声诸，貌似項(xiàng)目中的代碼，網(wǎng)絡(luò)請(qǐng)求滅有回調(diào)
__block NSURLResponse *urlResponse;
[networkHandler sendRequest:request
withSendingData:^(int64_t bytesSent, int64_t totalBytes) {}
withResponse:^(NSURLResponse *response) {
urlResponse = response;
}
withReceiveData:^(NSData *data) {}
withCompeletion:^(NSData *totalData, NSError *error) {
//TODO 304
if (!error && [urlResponse isKindOfClass:[NSHTTPURLResponse class]] && ((NSHTTPURLResponse *)urlResponse).statusCode != 200) {
error = [NSError errorWithDomain:WX_ERROR_DOMAIN
code:((NSHTTPURLResponse *)urlResponse).statusCode
userInfo:@{@"message":@"status code error."}];
}
if (error) {
NSString *errorMessage = [NSString stringWithFormat:@"Connection to %@ occurs an error:%@", request.URL, error.localizedDescription];
WX_MONITOR_FAIL_ON_PAGE(WXMTJSDownload, WX_ERR_JSBUNDLE_DOWNLOAD, errorMessage, weakSelf.pageName);
if (weakSelf.onFailed) {
weakSelf.onFailed(error);
}
return;
}
if (!totalData) {
NSString *errorMessage = [NSString stringWithFormat:@"Connection to %@ but no data return", request.URL];
WX_MONITOR_FAIL_ON_PAGE(WXMTJSDownload, WX_ERR_JSBUNDLE_DOWNLOAD, errorMessage, weakSelf.pageName);
if (weakSelf.onFailed) {
weakSelf.onFailed(error);
}
return;
}
NSString *script = [[NSString alloc] initWithData:totalData encoding:NSUTF8StringEncoding];
if (!script) {
WX_MONITOR_FAIL_ON_PAGE(WXMTJSDownload, WX_ERR_JSBUNDLE_STRING_CONVERT, @"data converting to string failed.", weakSelf.pageName)
return;
}
WX_MONITOR_SUCCESS_ON_PAGE(WXMTJSDownload, weakSelf.pageName);
WX_MONITOR_INSTANCE_PERF_END(WXPTJSDownload, weakSelf);
[weakSelf renderView:script options:newOptions data:data];
}];
再次更新
經(jīng)過多次調(diào)試發(fā)現(xiàn)以下問題:
WX_MONITOR_INSTANCE_PERF_START(WXPTJSDownload, self);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:[WXUtility userAgent] forHTTPHeaderField:@"User-Agent"];
[request setValue:@"weex" forHTTPHeaderField:@"f-refer"];
id<WXNetworkProtocol> networkHandler = [self networkHandler];
__block NSURLResponse *urlResponse;
[networkHandler sendRequest:request
withSendingData:^(int64_t bytesSent, int64_t totalBytes) {}
withResponse:^(NSURLResponse *response) {
urlResponse = response;
}
withReceiveData:^(NSData *data) {}
withCompeletion:^(NSData *totalData, NSError *error) {
//TODO 304
if (!error && [urlResponse isKindOfClass:[NSHTTPURLResponse class]] && ((NSHTTPURLResponse *)urlResponse).statusCode != 200) {
error = [NSError errorWithDomain:WX_ERROR_DOMAIN
code:((NSHTTPURLResponse *)urlResponse).statusCode
userInfo:@{@"message":@"status code error."}];
}
if (error) {
NSString *errorMessage = [NSString stringWithFormat:@"Connection to %@ occurs an error:%@", request.URL, error.localizedDescription];
WX_MONITOR_FAIL_ON_PAGE(WXMTJSDownload, WX_ERR_JSBUNDLE_DOWNLOAD, errorMessage, weakSelf.pageName);
if (weakSelf.onFailed) {
weakSelf.onFailed(error);
}
return;
}
if (!totalData) {
NSString *errorMessage = [NSString stringWithFormat:@"Connection to %@ but no data return", request.URL];
WX_MONITOR_FAIL_ON_PAGE(WXMTJSDownload, WX_ERR_JSBUNDLE_DOWNLOAD, errorMessage, weakSelf.pageName);
if (weakSelf.onFailed) {
weakSelf.onFailed(error);
}
return;
}
NSString *script = [[NSString alloc] initWithData:totalData encoding:NSUTF8StringEncoding];
if (!script) {
WX_MONITOR_FAIL_ON_PAGE(WXMTJSDownload, WX_ERR_JSBUNDLE_STRING_CONVERT, @"data converting to string failed.", weakSelf.pageName)
return;
}
WX_MONITOR_SUCCESS_ON_PAGE(WXMTJSDownload, weakSelf.pageName);
WX_MONITOR_INSTANCE_PERF_END(WXPTJSDownload, weakSelf);
[weakSelf renderView:script options:newOptions data:data];
}];
在我的項(xiàng)目中退盯，當(dāng)程序執(zhí)行到這個(gè)請(qǐng)求js文件的網(wǎng)絡(luò)方法時(shí)彼乌，不會(huì)走WXNetworkDefaultImpl中的創(chuàng)建請(qǐng)求的方法:
- (id)sendRequest:(NSURLRequest *)request withSendingData:(void (^)(int64_t, int64_t))sendDataCallback
withResponse:(void (^)(NSURLResponse *))responseCallback
withReceiveData:(void (^)(NSData *))receiveDataCallback
withCompeletion:(void (^)(NSData *, NSError *))compeletionCallback
{
WXNetworkCallbackInfo *info = [WXNetworkCallbackInfo new];
info.sendDataCallback = sendDataCallback;
info.responseCallback = responseCallback;
info.receiveDataCallback = receiveDataCallback;
info.compeletionCallback = compeletionCallback;
if (!_session) {
_session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]
delegate:self
delegateQueue:[NSOperationQueue mainQueue]];
}
NSURLSessionDataTask *task = [_session dataTaskWithRequest:request];
if (!_callbacks) {
_callbacks = [NSMutableDictionary dictionary];
}
[_callbacks setObject:info forKey:task];
[task resume];
return task;
}
所以導(dǎo)致js文件請(qǐng)求根本就沒有發(fā)出來，就去執(zhí)行了WXBridgeContext.m中的得问，下列代碼囤攀，由于sendQueue = nil然后結(jié)束了運(yùn)行
- (void)executeJsMethod:(WXBridgeMethod *)method
{
WXAssertBridgeThread();
if (!method.instance) {
WXLogError(@"Instance doesn't exist!");
return;
}
NSMutableArray *sendQueue = self.sendQueue[method.instance];
if (!sendQueue) {
WXLogInfo(@"No send queue for instance:%@, may it has been destroyed so method:%@ is ignored", method.instance, method.method);
return;
}
[sendQueue addObject:method];
[self performSelector:@selector(_sendQueueLoop) withObject:nil];
}
表示求同學(xué)解答下哈，實(shí)在是有點(diǎn)不太明白宫纬，我的所有配置和playground中一致焚挠，為啥會(huì)出現(xiàn)這樣的情況呢
解決了 這是一個(gè)尷尬的結(jié)果
是因?yàn)槲覍懙某跏蓟痵dk的方法沒有調(diào)用 : )
