我的这段代码到目前为止还无法发送 Facebook 请求。
NSDictionary *firstDict = [NSDictionary dictionaryWithObjectsAndKeys:
@"image", @"Type",
@"http://mysite.com/image.jpg", @"src",
@"http://mysite.com/page.html", @"href",
nil];
NSDictionary *secondDict = [NSDictionary dictionaryWithObjectsAndKeys:
@"image", @"Type",
@"http://mysite.com/image.jpg", @"src",
@"http://mysite.com/page.html", @"href",
nil];
NSArray *mediaArray = [[NSArray alloc] initWithObjects:firstDict, secondDict, nil];
NSArray *keys = [NSArray arrayWithObjects:@"name", @"description", @"href", @"media", nil];
NSArray *objects = [NSArray arrayWithObjects:
[NSString stringWithString:@"MyTitle"],
[NSString stringWithString:@"My caption"],
[NSString stringWithString:@"http://mysite.com/page.html"], mediaArray, nil];
NSDictionary *attachment = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
[[FBRequest requestWithDelegate:self] call:@"facebook.stream.publish" params:attachment];
我拿了这个样本:http://forum.developers.facebook.com/viewtopic.php?pid=145965
但是每次我运行它时,控制台都会显示以下内容:
{
"api_key" = adc8d70987098sdc;
"call_id" = 23456767;
description = "Any user's description";
format = XML;
href = "http://mysite.com/page.html";
media = (
{
Type = image;
href = "http://mysite.com/page.html";
src = "http://mysite.com/image.jpg";
},
{
Type = image;
href = "http://mysite.com/page.html";
src = "http://mysite.com/image.jpg";
}
);
method = "Facebook.streamPublish";
name = aName;
"session_key" = "d0f98bfs89b7fg7v";
sig = 89v0d9fv879fgv;
ss = 1;
v = "1.0"; }
它显示数组的圆括号而不是方括号,这正常吗?
然后显示错误:
*** -[NSCFArray dataUsingEncoding:]: unrecognized selector sent to instance
0x12fcb0 2009-10-30 13:54:27.758 GeoPixr[307:207]
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
*** -[NSCFArray dataUsingEncoding:]: unrecognized selector sent to instance 0x12fcb0
[ session 恢复]调用返回 TRUE。
提前致谢。
最佳答案
如果您使用最新的iOS SDK For Facebook然后使用下面的方法您可以将图像发布为流。
- (IBAction) publishStream: (id)sender { SBJSON *jsonWriter = [[SBJSON new] autorelease]; NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: @"Always Running",@"text",@"http://thinkdiff.net",@"href", nil], nil]; NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; NSDictionary* imageShare = [NSDictionary dictionaryWithObjectsAndKeys: @"image", @"type", @"http://thinkdiff.net/mahmud_small.jpg", @"src", @"http://thinkdiff.net", @"href", nil]; NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys: @"a long run", @"name", @"The Facebook Running app", @"caption", @"it is fun", @"description", @"http://itsti.me/", @"href", [NSArray arrayWithObjects:imageShare, nil ], @"media", nil]; NSString *attachmentStr = [jsonWriter stringWithObject:attachment]; NSLog(attachmentStr); NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: kAppId, @"api_key", @"Share on Facebook", @"user_message_prompt", actionLinksStr, @"action_links", attachmentStr, @"attachment", nil]; [_facebook dialog: @"stream.publish" andParams: params andDelegate:self]; }
图像部分应该是另一个 NSDictionary 对象。
NSDictionary* imageShare = [NSDictionary dictionaryWithObjectsAndKeys: @"image", @"type", @"http://thinkdiff.net/mahmud_small.jpg", @"src", @"http://thinkdiff.net", @"href", nil];
并且在附件中 NSDictionary 对象必须包含 imageShare 对象作为数组
[NSArray arrayWithObjects:imageShare, nil ]
这是因为如果您不将其包含为数组,Json 解析器会避免使用 [] 括号,因此发布功能将无法工作。请记住,该字符串必须是有效的 JSON 字符串,否则 facebook api 将不会发布。
