我有一個應用程序在錄製視頻。但是當錄製完成後,我無法立即保存視頻。我需要先表明一個協議。所以我嘗試保存從圖像選擇器獲得的URL。然後將視頻保存到圖書館。 這適用於iOS4,但不適用於iOS5。 我是iOS和Objective-C的新手,所以我可能對應該保存URL的屬性做了一些完全錯誤的聲明。存儲錄製的視頻URL以後保存到庫
這部分代碼:
.H
#import <UIKit/UIKit.h>
#import <AssetsLibrary/AssetsLibrary.h>
@interface Video_recViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate> {
NSURL *tempMoviePath;
}
@property (nonatomic, retain) NSURL *tempMoviePath;
的.m
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *moviePath = [info objectForKey:UIImagePickerControllerMediaURL];
[self dismissModalViewControllerAnimated: YES];
NSLog(@"path from image picker: %@", moviePath);
tempMoviePath = moviePath;
NSLog(@"temp movie path: %@", tempMoviePath);
//
[self performSelector:@selector(showAgree) withObject:nil afterDelay:0.5];
}
- (void)userAgreed {
NSLog(@"user agreed");
//NSLog(@"temp movie path: %@", tempMoviePath);
[self saveMyVideo:tempMoviePath];
//[self performSelector:@selector(showSurvey) withObject:nil afterDelay:0.5];
}
- (void)saveMyVideo:(NSURL *)videoURL {
NSLog(@"saving movie at: %@", videoURL);
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:videoURL])
{
[library writeVideoAtPathToSavedPhotosAlbum:videoURL
completionBlock:^(NSURL *assetURL, NSError *error){}
];
}
[library release];
}
輸出從日誌時didFinishPickingMediaWithInfo是:從
temp movie path: file://localhost/private/var/mobile/Applications/8CFD1CB7-70A0-465C-B730-817ACE5A4F78/tmp/capture-T0x119660.tmp.hNFzkY/capturedvideo.MOV
輸出記錄何時d oing「saveMyVideo」。網址突然變成了這個! :
