ReplayKit框架说明
- ReplayKit框架是苹果提供的录制视频的框架.
- 优点:录制流畅不卡顿
- 缺点:
- 不能定制预览页面
- 如果再次录制开始时间距离上次录制完成时间超过8分钟,还会弹框提示录制权限
- 默认保存到相册,不能指定保存路径.
- ReplayKit只支持ios9+,部分最新函数只支持10+
开始录制
- #import <ReplayKit/ReplayKit.h>
- 添加代理 <RPScreenRecorderDelegate, RPPreviewViewControllerDelegate>
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSKeyValueChangeKey,id> *)change context:(void *)context
{
if ([keyPath isEqualToString:@"recording"]) {
NSLog(@"keyPath === %@",object);
if ([change valueForKey:@"recording"] == 0) {
NSLog(@"可以录制");
}else
{
NSLog(@"++++++++++++不可以");
}
}
}
//开始录屏
- (void)startRecoding
{
//将开启录屏功能的代码放在主线程执行
// __weak typeof (self)weakSelf = self;
dispatch_async(dispatch_get_main_queue(), ^{
if ([[RPScreenRecorder sharedRecorder] isAvailable] && [self isSystemVersionOk]) { //判断硬件和ios版本是否支持录屏
NSLog(@"支持ReplayKit录制");
//这是录屏的类
RPScreenRecorder* recorder = RPScreenRecorder.sharedRecorder;
recorder.delegate = self;
//开起录屏功能
//9.0+函数(在10+版本被废弃,替换为startRecordingWithHandler:)
[recorder startRecordingWithMicrophoneEnabled:YES handler:^(NSError * _Nullable error) {
recorder.microphoneEnabled = YES;
if (error) {
IsDecoderScreen = 0;
NSLog(@"========%@",error.description);
[self showAlert:@"录制失败" andMessage:@"启动录制失败请重试!"];
startRecordScreenBtn.backgroundColor = [UIColor greenColor];
[startRecordScreenBtn setTitle:@"录屏" forState:UIControlStateNormal];
} else {
if (recorder.recording) {
startRecordScreenBtn.backgroundColor = [UIColor redColor];
[startRecordScreenBtn setTitle:@"结束录屏" forState:UIControlStateNormal];
//记录是否开始录屏 系统也有一个再带的检测是否在录屏的方法 (@property (nonatomic, readonly, getter=isRecording) BOOL recording;)
IsDecoderScreen = 1;
}
}
}];
//10.0+函数
//在此可以设置是否允许麦克风（传YES即是使用麦克风，传NO则不是用麦克风）
// recorder.microphoneEnabled = YES;
// recorder.cameraEnabled = YES;
// [recorder startRecordingWithHandler:^(NSError * _Nullable error) {
//
// //在此可以设置是否允许麦克风（传YES即是使用麦克风，传NO则不是用麦克风）(ios 后被废弃了 下面的这个开始录屏)
// // [recorder startRecordingWithMicrophoneEnabled:YES handler:^(NSError * _Nullable error) {
// recorder.microphoneEnabled = YES;
// if (error) {
// IsDecoderScreen = 0;
// NSLog(@"========%@",error.description);
// [self showAlert:@"录制失败" andMessage:@"启动录制失败请重试!"];
// startRecordScreenBtn.backgroundColor = [UIColor greenColor];
// [startRecordScreenBtn setTitle:@"录屏" forState:UIControlStateNormal];
// } else {
// if (recorder.recording) {
// startRecordScreenBtn.backgroundColor = [UIColor redColor];
// [startRecordScreenBtn setTitle:@"结束录屏" forState:UIControlStateNormal];
// //记录是否开始录屏 系统也有一个再带的检测是否在录屏的方法 (@property (nonatomic, readonly, getter=isRecording) BOOL recording;)
// IsDecoderScreen = 1;
// }
// }
// }];
} else {
[self showAlert:@"设备不支持录制" andMessage:@"升级ios系统"];
return;
}
});
}
结束录制
//结束录屏
- (void)stopRecording
{
__weak typeof (self)weakSelf = self;
[[RPScreenRecorder sharedRecorder] stopRecordingWithHandler:^(RPPreviewViewController *previewViewController, NSError * error){
_RPPreview = previewViewController;
if (error) {
NSLog(@"这里关闭有误%@",error.description);
[self showAlert:@"结束录制失败" andMessage:@"本次保存失败!请重新录制"];
startRecordScreenBtn.backgroundColor = [UIColor greenColor];
[startRecordScreenBtn setTitle:@"录屏" forState:UIControlStateNormal];
} else {
[_RPPreview setPreviewControllerDelegate:self];
startRecordScreenBtn.backgroundColor = [UIColor greenColor];
[startRecordScreenBtn setTitle:@"录屏" forState:UIControlStateNormal];
IsDecoderScreen = 0;
//在结束录屏时显示预览画面
[weakSelf showVideoPreviewController:_RPPreview withAnimation:YES];
}
}];
}
预览保存/取消
//显示视频预览页面,animation=是否要动画显示
- (void)showVideoPreviewController:(RPPreviewViewController *)previewController withAnimation:(BOOL)animation {
if (previewController==nil) {
return;
}
__weak typeof (self) weakSelf = self;
//UI需要放到主线程
dispatch_async(dispatch_get_main_queue(), ^{
CGRect rect = previewController.view.frame;
if (animation) {
rect.origin.x += rect.size.width;
previewController.view.frame = rect;
rect.origin.x -= rect.size.width;
[UIView animateWithDuration:0.3 animations:^(){
previewController.view.frame = rect;
} completion:^(BOOL finished){
}];
} else {
previewController.view.frame = rect;
}
[weakSelf.view addSubview:previewController.view];
[weakSelf addChildViewController:previewController];
});
}
//关闭视频预览页面，animation=是否要动画显示
- (void)hideVideoPreviewController:(RPPreviewViewController *)previewController withAnimation:(BOOL)animation {
//UI需要放到主线程
dispatch_async(dispatch_get_main_queue(), ^{
CGRect rect = previewController.view.frame;
if (animation) {
rect.origin.x += rect.size.width;
[UIView animateWithDuration:0.3 animations:^(){
previewController.view.frame = rect;
} completion:^(BOOL finished){
//移除页面
[previewController.view removeFromSuperview];
[previewController removeFromParentViewController];
}];
} else {
//移除页面
[previewController.view removeFromSuperview];
[previewController removeFromParentViewController];
}
});
}
ReplayKit代理实现
#pragma mark - RPPreviewViewControllerDelegate
//关闭的回调
- (void)previewControllerDidFinish:(RPPreviewViewController *)previewController {
if (isSave == 1) {
//这个地方我添加了一个延时,我发现这样保存不到系统相册的情况好多了
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(4 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[self hideVideoPreviewController:_RPPreview withAnimation:YES];
});
isSave = 0;
}else {
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertAction *queding = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[self hideVideoPreviewController:_RPPreview withAnimation:YES];
// dispatch_async(dispatch_get_main_queue(), ^{
// [weakSelf.RPPreview dismissViewControllerAnimated:YES completion:nil];
// });
isSave = 0;
}];
UIAlertAction *actionCancel = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"录制未保存\n确定要取消吗" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:actionCancel];
[alert addAction:queding];
[self presentViewController:alert animated:NO completion:nil];
});
}
}
//选择了某些功能的回调（如分享和保存）
- (void)previewController:(RPPreviewViewController *)previewController didFinishWithActivityTypes:(NSSet <NSString *> *)activityTypes {
__weak typeof (self)weakSelf = self;
if ([activityTypes containsObject:@"com.apple.UIKit.activity.SaveToCameraRoll"]) {
isSave = 1;
NSLog(@"***************************");
//这个地方我延时执行,等预览画面移除后再显示提示框
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(4 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
dispatch_async(dispatch_get_main_queue(), ^{
[weakSelf showAlert:@"保存成功" andMessage:@"已经保存到系统相册"];
[self uploadVideoAsyn];//上传数据
});
});
}
if ([activityTypes containsObject:@"com.apple.UIKit.activity.CopyToPasteboard"]) {
dispatch_async(dispatch_get_main_queue(), ^{
[weakSelf showAlert:@"复制成功" andMessage:@"已经复制到粘贴板"];
});
}
}
#pragma mark ====RPScreenDelegate===
- (void)screenRecorderDidChangeAvailability:(RPScreenRecorder *)screenRecorder
{
// [screenRecorder addObserver:self forKeyPath:@"recording" options:NSKeyValueObservingOptionNew context:nil];
// [screenRecorder setValue:@"1" forKey:@"recording"];
NSLog(@" delegate ======%@",screenRecorder);
}
- (void)screenRecorder:(RPScreenRecorder *)screenRecorder didStopRecordingWithError:(NSError *)error previewViewController:(nullable RPPreviewViewController *)previewViewController
{
[_RPPreview setPreviewControllerDelegate:self];
startRecordScreenBtn.backgroundColor = [UIColor greenColor];
[startRecordScreenBtn setTitle:@"录屏" forState:UIControlStateNormal];
IsDecoderScreen = 0;
[self showVideoPreviewController:_RPPreview withAnimation:YES];
}
其他补充方法
//显示弹框提示
- (void)showAlert:(NSString *)title andMessage:(NSString *)message {
if (!title) {
title = @"";
}
if (!message) {
message = @"";
}
UIAlertAction *actionCancel = [UIAlertAction actionWithTitle:@"好的" style:UIAlertActionStyleCancel handler:nil];
UIAlertController *alert = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:actionCancel];
[self presentViewController:alert animated:NO completion:nil];
}
//判断对应系统版本是否支持ReplayKit
- (BOOL)isSystemVersionOk {
if ([[UIDevice currentDevice].systemVersion floatValue] < 9.0) {
return NO;
} else {
return YES;
}
}
相册转移到沙盒并从沙盒上传到服务器
- 保存到相册后就能把数据转到沙盒,从而上传到服务器了
- (void)uploadVideoAsyn{}
- 实现思路,参照我的另一篇文章:
