[英]iOS Facebook sdk 4.0 share an image
我正在嘗試使用新的facebook sdk 4.0共享圖像。 我在facebook示例中使用了相同的代碼,但是在嘗試顯示FBSDKShareDialog
時遇到了此異常。
*由於未捕獲的異常'NSInvalidArgumentException'而終止應用程序,原因:'無法解析格式字符串“ SELF NOT NULL”'*首先拋出調用棧:(0 CoreFoundation 0x000000010b782a75 __exceptionPreprocess + 165 1 libobjc.A.dylib

這是代碼
- (UIAlertAction*) createActionForFacebookWithMediaPath:(NSString*) path andMediaType:(MediaType) mediaType {
NSString * mediaName = mediaType == kMediaTypeImage ? NSLocalizedString(@"KEY_IMAGE", nil) : NSLocalizedString(@"KEY_VIDEO", nil);
UIAlertAction* facebookAction = [UIAlertAction actionWithTitle:[NSString stringWithFormat:@"%@ %@",NSLocalizedString(@"KEY_SHARE_YOUR", nil),mediaName] style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
NSObject<FBSDKSharingContent> * content = nil;
if (mediaType == kMediaTypeImage) {
NSURL * fileURL = [NSURL URLWithString:path];
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.imageURL = fileURL;
// photo.userGenerated = YES;
FBSDKSharePhotoContent * photoContent = [[FBSDKSharePhotoContent alloc] init];
photoContent.photos = @[photo];
content = photoContent;
}
else if (mediaType == kMediaTypeVideo) {
NSURL *videoURL = [NSURL fileURLWithPath:path];
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = videoURL;
FBSDKShareVideoContent * videoContent = [[FBSDKShareVideoContent alloc] init];
videoContent.video = video;
content = videoContent;
}
[FBSDKShareDialog showFromViewController:self
withContent:content
delegate:nil];
}];
return facebookAction;
}
- (UIAlertAction*) createActionForCameraRollWithMediaPath:(NSString*) path andMediaType:(MediaType) mediaType {
return nil;
}
- (void) showShareOptionsForMediaPath:(NSString*)path {
UIAlertController * alertControl =[UIAlertController alertControllerWithTitle:NSLocalizedString(@"KEY_SHARE_TITLE", nil) message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction * cancelAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"KEY_CANCEL", nil) style:UIAlertActionStyleCancel handler:NULL];
[alertControl addAction:cancelAction];
MediaType mediaType = [self checkMediaTypeAtPath:path];
switch (mediaType) {
case kMediaTypeImage:
{
UIAlertAction * fbAction =[self createActionForFacebookWithMediaPath:path andMediaType:kMediaTypeImage];
[alertControl addAction:fbAction];
}
break;
case kMediaTypeVideo:
{
UIAlertAction * fbAction =[self createActionForFacebookWithMediaPath:path andMediaType:kMediaTypeVideo];
[alertControl addAction:fbAction];
}
break;
case kMediaTypeUnknown:
{
//EXCEPTION
}
break;
default:
break;
}
[self presentViewController:alertControl animated:YES completion:nil];
}
首先,我創建一個顯示共享選項的UIAlertController,並添加相對的UIAlertAction
,當我調用共享對話框時會生成異常。
有什么建議嗎?
此問題將在下一個SDK版本中修復。
顯然,您可以從FBSDKShareDialog中刪除以下行,並從源代碼構建框架以解決該問題。 https://github.com/facebook/facebook-ios-sdk/blob/master/FBSDKShareKit/FBSDKShareKit/FBSDKShareDialog.m#L442
