Facebook的照片

问题描述

我需要在Facebook上上传照片。但似乎是不可能的。我总是在控制台中有相同的崩溃[UIImage dataUsingEncoding：]
我得到我的图像的方式：

   - （ void）imagePickerController：（UIImagePickerController *）picker didFinishPickingMediaWithInfo：（NSDictionary *）info {
 [self dismissModalViewControllerAnimated：YES]; 
 if（[mediaType isEqualToString：@public.image]）{
 _photoImage1 = [[info objectForKey：@UIImagePickerControllerOriginalImage] retain]; 
  

所有需要的权限：

   - （void）uploadPhotoToFacebook {
 NSMutableDictionary * args = [[[NSMutableDictionary alloc] init] autorelease]; 
 [args setObject：_photoImage1 forKey：@image]; 
 [args setObject：@hello test pictureforKey：@caption]; 
 FBRequest * uploadPhotoRequest = [FBRequest requestWithDelegate：self]; 
 [uploadPhotoRequest call：@photos.uploadparams：args]; 
  

它在FBRequest.m中的这种方法之后崩溃了

$ b $（$）$（$）$（$）$（$）$（$）$（$）$（$）

}
提前感谢

解决方案

尝试添加图像为dataParam

  NSMutableDictionary * params = [[[ NSMutableDictionary alloc] init] autorelease]; 
 [params setObject：@NAMEforKey：@caption]; 
 [[FBRequest requestWithDelegate：self] call：@facebook.photos.uploadparams：params dataParam：UIImagePNGRepresentation（_photoImage1）]; 
  

I need to upload photo on Facebook. But it seems to be impossible. I always have the same crash in console [UIImage dataUsingEncoding:]The way I get my Image:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
[self dismissModalViewControllerAnimated:YES];
if ([mediaType isEqualToString:@"public.image"]){
    _photoImage1 = [[info objectForKey:@"UIImagePickerControllerOriginalImage"] retain];

After all needed permissions:

-(void)uploadPhotoToFacebook {
NSMutableDictionary *args = [[[NSMutableDictionary alloc] init] autorelease];
[args setObject:_photoImage1 forKey:@"image"];
[args setObject:@"hello test picture" forKey:@"caption"];
FBRequest *uploadPhotoRequest = [FBRequest requestWithDelegate:self];
[uploadPhotoRequest call:@"photos.upload" params:args];

It has crash after such a method in FBRequest.m

- (void)utfAppendBody:(NSMutableData*)body data:(NSString*)data {
[body appendData:[data dataUsingEncoding:NSUTF8StringEncoding]];

}Thanks in advance.

解决方案

Try to add image as dataParam

NSMutableDictionary *params = [[[NSMutableDictionary alloc] init] autorelease];
[params setObject:@"NAME" forKey:@"caption"];
[[FBRequest requestWithDelegate:self] call:@"facebook.photos.upload" params:params dataParam:UIImagePNGRepresentation(_photoImage1)];
