我正在使用ALAssert
库从 iPhone 库中选择视频,并且我正在设置该视频文件的属性,例如。
(void)selectedAssets:(NSArray*)_assets {
NSMutableArray *returnArray = [[[NSMutableArray alloc] init] autorelease];
for(ALAsset *asset in _assets) {
NSMutableDictionary *workingDictionary = [[NSMutableDictionary alloc] init];
[workingDictionary setObject:[asset valueForProperty:ALAssetPropertyType] forKey:@"UIImagePickerControllerMediaType"];
[workingDictionary setObject:[UIImage imageWithCGImage:[[asset defaultRepresentation] fullScreenImage]] forKey:@"UIImagePickerControllerOriginalImage"];
[workingDictionary setObject:[[asset valueForProperty:ALAssetPropertyURLs] valueForKey:[[[asset valueForProperty:ALAssetPropertyURLs] allKeys] objectAtIndex:0]] forKey:@"UIImagePickerControllerReferenceURL"];
[workingDictionary setObject:[[asset defaultRepresentation]url] forKey:@"UIImagePickerControllerMediaURL"];
[returnArray addObject:workingDictionary];
[workingDictionary release];
}
[self popToRootViewControllerAnimated:NO];
[[self parentViewController] dismissModalViewControllerAnimated:YES];
if([delegate respondsToSelector:@selector(elcImagePickerController:didFinishPickingMediaWithInfo:)]) {
[delegate performSelector:@selector(elcImagePickerController:didFinishPickingMediaWithInfo:) withObject:self withObject:[NSArray arrayWithArray:returnArray]];
}
}
我在这里设置,但我认为这不是我所做的所有UIImagePickerControllerMediaURL
设置的权利。UIImagePickerControllerMediaURL
我如何UIImagePickerControllerMediaURL
为选定的视频提供属性。并将该视频转换MediaURL
为数据类型。
