iOS上传视频到服务器，这里介绍用AFN上传本地拍摄的视频到服务端。
关于更多iOS视频操作方面的知识，可以阅读的iOS视频录制、压缩导出、取帧这篇文章。
//视频转换为MP4
//转码操作...

}记得上传成功之后要删除沙盒中的视频文件哦！代码奉上。
-(void)ClearMovieFromDoucments{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *contents = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:NULL];
NSEnumerator *e = [contents objectEnumerator];
NSString *filename;
while ((filename = [e nextObject])) {
MyLog(@"%@",filename);
if ([filename isEqualToString:@"tmp.PNG"]) {
MyLog(@"删除%@",filename);
[fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:filename] error:NULL];
continue;
}
if ([[[filename pathExtension] lowercaseString] isEqualToString:@"mp4"]||
[[[filename pathExtension] lowercaseString] isEqualToString:@"mov"]||
[[[filename pathExtension] lowercaseString] isEqualToString:@"png"]) {
MyLog(@"删除%@",filename);
[fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:filename] error:NULL];
}
}
}好，整体思路已经清楚，拿到视频资源，先转为mp4，写进沙盒，然后上传，上传成功后要记得删除沙盒中的文件。
