ios 自帶錄屏框架replayKit的使用
編輯：IOS開發綜合
前幾個月第一次做關於ios錄屏的功能,在網上看到有關於replaykit的介紹,總結之後集成到項目中,初步達到了項目要求的錄屏的功能,但是在後續的測試發現,有錄屏出現黑屏的情況,也有不能保存到系統系統相冊的情況,後來及時改改邏輯,調用順序就解決,現在是沒什麼問題了,但是感覺也不是太穩定,還沒正式的使用,還不能確定不會出現問題,現在,把代碼貼出來,歡迎指導指正
replaykit是ios9後出的,所以replaykit支持ios9+錄屏,
//開始錄屏
- (void)StartRecoder
{
//將開啟錄屏功能的代碼放在主線程執行
dispatch_async(dispatch_get_main_queue(), ^{
if ([[RPScreenRecorder sharedRecorder] isAvailable] && [self isSystemVersionOk]) { //判斷硬件和ios版本是否支持錄屏
NSLog(@"支持ReplayKit錄制");
//這是錄屏的類
RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;
recorder.delegate = self;
__weak typeof (self)weakSelf = self;
MBProgressHUD *hud;
hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.maskView.hidden = NO;

}
}];
//在此可以設置是否允許麥克風（傳YES即是使用麥克風，傳NO則不是用麥克風）
recorder.microphoneEnabled = YES;
recorder.cameraEnabled = YES;
//開起錄屏功能
[recorder startRecordingWithHandler:^(NSError * _Nullable error) {
//在此可以設置是否允許麥克風（傳YES即是使用麥克風，傳NO則不是用麥克風）(ios 後被廢棄了 下面的這個開始錄屏)
