在我的應用程序中,我使用FBWebDialogs來發送應用程序請求Facebook的朋友,我做到了成功。我的問題是我不能處理FBWebDialog彈出窗口按鈕。在下面的代碼中,我可以檢測到X按鈕和取消按鈕,但是當我選擇發送按鈕時,它仍然給出日誌NSLog(@"User canceled request.");
我使用facebook文檔中給出的代碼。我的錯誤是什麼?iphone開發:如何處理fbwebdialogs彈出按鈕
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:@"Learn how to make your iOS apps social."
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
// Error launching the dialog or sending the request.
NSLog(@"Error sending request.");
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(@"User canceled request.");
} else {
// Handle the send request callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if (![urlParams valueForKey:@"request"]) {
// User clicked the Cancel button
NSLog(@"User canceled request.");
} else {
// User clicked the Send button
NSString *requestID = [urlParams valueForKey:@"request"];
NSLog(@"Request ID: %@", requestID);
}
}
}
}];
而且我有parseURLParams功能類似:
- (NSDictionary*)parseURLParams:(NSString *)query {
NSArray *pairs = [query componentsSeparatedByString:@"&"];
NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
for (NSString *pair in pairs) {
NSArray *kv = [pair componentsSeparatedByString:@"="];
NSString *val =
[[kv objectAtIndex:1]
stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[params setObject:val forKey:[kv objectAtIndex:0]];
}
return params;
}
