ELCImagePickerController的索引视图

Question

可能重复：

Adding a UIActivityIndicator to a modal view (ELCimagepicker)

如何将指标视图集成到ELCImagePickerController中。我很难做到这一点。我也提到了这个question，但它没有答案。我也为发布集成代码发表了评论，但还没有找到好消息。

请帮帮忙。

我已经解决了你的问题。你可以这样做如下..。

-(void)selectedAssets:(NSArray*)_assets {

ELCImagePickerDemoAppDelegate * appDelegate = (ELCImagePickerDemoAppDelegate *)[[UIApplication sharedApplication] delegate];

UIActivityIndicatorView * activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.center = CGPointMake(appDelegate.window.frame.size.width/2, appDelegate.window.frame.size.height/2);
[activityIndicator setHidden:NO];
[activityIndicator setTag:1001];
[appDelegate.window addSubview:activityIndicator];
[appDelegate.window bringSubviewToFront:activityIndicator];
[activityIndicator startAnimating];

[self performSelector:@selector(doProcess:) withObject:_assets afterDelay:2.1];
}


- (void) doProcess:(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"];

    [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]];
}

}

毕竟，当您想要删除活动指示器时。可以在下面写代码。

ELCImagePickerDemoAppDelegate *app = (ELCImagePickerDemoAppDelegate *)[[UIApplication sharedApplication] delegate];
[[app.window viewWithTag:1001] removeFromSuperview];

如果这个答案对你有帮助..。

谢谢,
