问题描述
到目前为止，我知道如何流式传输视频以及如何下载视频，然后再进行流式传输，但有一点很棘手:流式传输一次，将其存储在设备上，以后再从设备上播放.
So far I know how to stream a video and how to download it and afterwards stream it, but here's the tricky bit: streaming it once, storing it on the device and in the future play it from the device.
这可能吗?
推荐答案
保存视频非常简单.做类似的事情:
It's quite easy to save the video. Do something similar to this:
//Saving Movie
NSMutableData *data = [[NSMutableData alloc] init];
NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data];
[archiver encodeObject:*MovieObject* forKey:@"MovieObjectDataKey"];
[archiver finishEncoding];
[[NSUserDefaults standardUserDefaults] setObject:data forKey:@"MovieObjectDefaultsDataKey"];
[archiver release];
[data release];
//Retrieving movie
NSData *savedMovieData = [[NSUserDefaults standardUserDefaults] objectForKey:@"MovieObjectDefaultsDataKey"];
if (savedMovieData != nil) {
NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:savedMovieData];
*MovieObject* = [[unarchiver decodeObjectForKey:@"MovieObjectDataKey"] retain];
[unarchiver finishDecoding];
[savedMovieData release];
[unarchiver release];
} else {
//Download Stream of Your Movie
}
你真正需要改变的只有 * MovieObject *，每一步都要改变一次.
The only thing you really have to change there is * MovieObject *, once in each step.
