我使用 stackoverflow 上的帖子在 iPhone 上实现了“添加朋友”对话框：
Facebook 朋友对话框返回“未知方法”错误，它是为 Android 实现的，但很容易转换为 iPhone。
它工作正常，直到几天前它停止工作，现在它给我一个错误：
HitMe 发生错误。请稍后再试。
API 错误代码：3
API 错误描述：未知方法
错误消息：此显示类型不支持此方法
我尝试在 facebook 路线图中搜索：https ://developers.facebook.com/roadmap/但找不到任何提及更改的内容，是否有人遇到过此问题或知道在 iPhone 上实现“好友请求”对话框的另一种方法?
这是我为实现“好友请求”对话框而对 Facebook 2.0 sdk 所做的更改：
在 Facebook.m 中的 dialog:andParams:andDelegate: 方法中，我将原始代码替换为以下代码：
-(void)dialog:(NSString *)action
andParams:(NSMutableDictionary *)params
andDelegate:(id <FBDialogDelegate>)delegate {
[_fbDialog release];
NSString *dialogURL;
if ([action isEqualToString:kFriends])
{
dialogURL = [kDialogBaseURLForFriends stringByAppendingString:action];
}
else
{
dialogURL = [kDialogBaseURL stringByAppendingString:action];
}
if ([action isEqualToString:kFriends])
{
[params setObject:@"popup" forKey:@"display"];
}
else
{
[params setObject:@"touch" forKey:@"display"];
}
[params setObject:kSDKVersion forKey:@"sdk"];
[params setObject:kRedirectURL forKey:@"redirect_uri"];
if ([action isEqualToString:kLogin]) {
[params setObject:@"user_agent" forKey:@"type"];
_fbDialog = [[FBLoginDialog alloc] initWithURL:dialogURL loginParams:params delegate:self];
} else {
[params setObject:_appId forKey:@"app_id"];
if ([self isSessionValid]) {
[params setValue:[self.accessToken stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
forKey:@"access_token"];
[self extendAccessTokenIfNeeded];
}
// by default we show dialogs, frictionless cases may have a hidden view
BOOL invisible = NO;
// frictionless handling for application requests
if ([action isEqualToString:kApprequests]) {
// if frictionless requests are enabled
if (self.isFrictionlessRequestsEnabled) {
// 1. show the "Don't show this again for these friends" checkbox
// 2. if the developer is sending a targeted request, then skip the loading screen
[params setValue:@"1" forKey:@"frictionless"];
// 3. request the frictionless recipient list encoded in the success url
[params setValue:@"1" forKey:@"get_frictionless_recipients"];
}
// set invisible if all recipients are enabled for frictionless requests
id fbid = [params objectForKey:@"to"];
if (fbid != nil) {
// if value parses as a json array expression get the list that way
SBJsonParser *parser = [[[SBJsonParser alloc] init] autorelease];
id fbids = [parser objectWithString:fbid];
if (![fbids isKindOfClass:[NSArray class]]) {
// otherwise seperate by commas (handles the singleton case too)
fbids = [fbid componentsSeparatedByString:@","];
}
invisible = [self isFrictionlessEnabledForRecipients:fbids];
}
}
_fbDialog = [[FBDialog alloc] initWithURL:dialogURL
params:params
isViewInvisible:invisible
frictionlessSettings:_frictionlessRequestSettings
delegate:delegate];
}
[_fbDialog show];
}
其中 kFriends 是 @"friends" 而 kDialogBaseURLForFriends 是 @" https://facebook.com/dialog/ "
