關(guān)于Replaykit日志/寫入文件的問題的問題.
1.replaykit寫入的文件怎么獲取...
思路:利用Appgroup. 先把文件寫入到沙盒,然后在擴(kuò)展還在運(yùn)行的時(shí)候,把擴(kuò)展的日志copy到沙盒.
擴(kuò)展代碼:

因?yàn)槲沂卿浧翆懭隻uffer 數(shù)據(jù)的,所以,我在錄屏開始的時(shí)候調(diào)用了
saveToFile
然后我在每一幀回調(diào)的時(shí)候都調(diào)用了.起到保存每一幀的問題..
+ (void)savePixel:(CMSampleBufferRef)sampleBuffer
延時(shí)結(jié)束是因?yàn)殇浿频膟uv 數(shù)據(jù)很大.我們?cè)趯?shí)際開發(fā)者中可根據(jù)這個(gè)做修改.
最后在主進(jìn)程進(jìn)行文件的copy動(dòng)作.切記 一定要擴(kuò)展進(jìn)程活躍的時(shí)候執(zhí)行copy
最好是在主進(jìn)程寫一個(gè)按鈕,點(diǎn)一下這個(gè)按鈕就執(zhí)行copy的動(dòng)作!
-(void)copyBufferFile{
NSURL *groupURL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"你們的APPgroupID"];
NSString *fileURL = [groupURL URLByAppendingPathComponent:@"Library/Caches/system.yuv"].path;
BOOL a = [[NSFileManager defaultManager] fileExistsAtPath:fileURL isDirectory:nil];
if (!a) {
return;
}
NSString *distDirectory = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).firstObject;
NSString * dispatch = [NSString stringWithFormat:@"%@/system.yuv",distDirectory];
[[NSFileManager defaultManager]removeItemAtPath:dispatch error:nil];
NSError *error = nil;
[[NSFileManager defaultManager]moveItemAtPath:fileURL toPath:dispatch error:&error];
if (error) {
NSLog(@"%@",error);
}
}
這樣就可以在主進(jìn)程的沙盒文件拿到擴(kuò)展進(jìn)程的日志或者資源了.另說一句.Replaykit 有很多坑.后續(xù)我會(huì)慢慢整理出來. 因?yàn)榫?個(gè)文件,就不上傳git了.大佬們見諒一下.不過代碼我已經(jīng)完整的貼出來了.至于APPGroup 怎么搞,順便說一句
選中項(xiàng)目的 targets 然后 點(diǎn)擊 +capability 然后選擇 appGroup 即可 圖就不截了
