我无法同时获取Facebook名称和图片。每个请求我只能接受其中一个。
-(void)fbDidLogin{
// Save the access token key info.
[self saveAccessTokenKeyInfo];
// Get the user's info.
[facebook requestWithGraphPath:@"me/?fields=first_name,picture" andDelegate:self];
}
-(void)request:(FBRequest *)request didLoad:(id)result{
if ([result isKindOfClass:[NSArray class]]) {
result = [result objectAtIndex:0];
if ([result objectForKey:@"first_name"]) {
[lblUser setText:[NSString stringWithFormat:@"Welcome %@!", [result objectForKey:@"first_name"]]];
// Show the publish button.
[btnPublish setHidden:NO];
}
}
else {
imageView.image = [UIImage imageWithData:result];
}
}
我得到的错误
__NSCFDictionary length]: unrecognized selector sent to instance
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary length]: unrecognized selector sent to instance
如果我有两个要求
-(void)fbDidLogin{
// Save the access token key info.
[self saveAccessTokenKeyInfo];
// Get the user's info.
[facebook requestWithGraphPath:@"me/picture" andDelegate:self];
[facebook requestWithGraphPath:@"me" andDelegate:self];
}
并使用相同的-(void)request:(FBRequest *)request didLoad:(id)result
我得到的错误是
[__NSCFDictionary length]: unrecognized selector sent to instance
所以我该如何请求获取Facebook名称和图片以及如何处理传入数据?
最佳答案
我已修复它,以下代码可以正常工作以获取Facebook名称和个人资料图片
-(void)request:(FBRequest *)request didLoad:(id)result{
// With this method we’ll get any Facebook response in the form of an array.
// In this example the method will be used twice. Once to get the user’s name to
// when showing the welcome message and next to get the ID of the published post.
// Inside the result array there the data is stored as a NSDictionary.
if ([result isKindOfClass:[NSData class]])
{
NSLog(@"Profile Picture");
imageView.image = [UIImage imageWithData:result];
//[profilePicture release];
//profilePicture = [[UIImage alloc] initWithData: result];
}
if ([result isKindOfClass:[NSArray class]]) {
// The first object in the result is the data dictionary.
result = [result objectAtIndex:0];
}
if ([result isKindOfClass:[NSDictionary class]]) {
// If the current result contains the "first_name" key then it's the user's data that have been returned.
// Change the lblUser label's text.
[lblUser setText:[NSString stringWithFormat:@"Welcome %@!", [result objectForKey:@"first_name"]]];
// Show the publish button.
[btnPublish setHidden:NO];
}
}
