Able to touch the background of activity indicator - iphone

Question

In my iphone application an activity indicator is shown at the time of webservice call. My problem is that i am able to touch the view on which the activity indicator is shown.My view has textfields and buttons and i am able to enter values in the text fields and also change the button states while the activity indicator is still on it. Have anybody faced a similar situation? Does anybody know a solution to this problem? All helpful suggestions are welcomed.
Here is my activity indicator class.
ActivityProgressViewController.h
#import <UIKit/UIKit.h>
#interface ActivityProgressViewController : UIViewController {
IBOutlet UIActivityIndicatorView *_activityIndicator;
IBOutlet UILabel *_labelMessage;
NSString *_messageToShow;
}
#property (nonatomic, retain) IBOutlet UIActivityIndicatorView *activityIndicator;
#property (nonatomic, retain) IBOutlet UILabel *labelMessage;
+ (ActivityProgressViewController*) createInstance;
- (void)show;
- (void)showWithMessage:(NSString*)message;
- (void)close;
+ (void)show;
+ (void)close;
#end
ActivityProgressViewController.m
#import "ActivityProgressViewController.h"
#define kACTIVITY_INDICATOR_NIB #"ActivityProgressViewController"
#implementation ActivityProgressViewController
#synthesize activityIndicator = _activityIndicator;
#synthesize labelMessage = _labelMessage;
static ActivityProgressViewController *_viewController;
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
}
- (void)viewDidLoad {
if (_messageToShow) _labelMessage.text = _messageToShow;
}
- (void)dealloc {
[_labelMessage release];
[_messageToShow release];
[_activityIndicator release];
[super dealloc];
}
+ (ActivityProgressViewController*) createInstance {
_viewController = [[ActivityProgressViewController alloc] initWithNibName:kACTIVITY_INDICATOR_NIB bundle:nil];
return _viewController;
}
- (void)show
{
[_activityIndicator startAnimating];
UIWindow *window = [[[UIApplication sharedApplication] windows]objectAtIndex:0];
NSLog(#"[[UIApplication sharedApplication] windows]===%#",[[UIApplication sharedApplication] windows]);
self.view.frame = CGRectMake(window.bounds.origin.x, window.bounds.origin.y, window.bounds.size.width, window.bounds.size.height);
[window addSubview:self.view];
}
- (void)showWithMessage:(NSString*)message {
_messageToShow = message;
[self show];
}
- (void)close
{
[self.view removeFromSuperview];
}
+ (void)show {
if (!_viewController) {
_viewController = [ActivityProgressViewController createInstance];
}
[_viewController show];
}
+ (void)close {
if (_viewController) {
[_viewController close];
}
}
#end
Here is how i call from my required class.
[ActivityProgressViewController show];
[ActivityProgressViewController close];
I also call the activity indicator while exporting audio.
This is the code I use for exporting
-(void)exportAudioFile:(AVComposition*)combinedComposition
{
[ActivityProgressViewController show];
AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:combinedComposition
presetName:AVAssetExportPresetPassthrough];
NSArray *presets =[AVAssetExportSession exportPresetsCompatibleWithAsset:combinedComposition];
NSLog(#"presets======%#",presets);
NSLog (#"can export: %#", exportSession.supportedFileTypes);
NSArray *dirs = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [dirs objectAtIndex:0];
exportPath = [documentsDirectoryPath stringByAppendingPathComponent:#"CombinedNew.m4a"];
[[NSFileManager defaultManager] removeItemAtPath:exportPath error:nil];
exportURL = [NSURL fileURLWithPath:exportPath];
exportSession.outputURL = exportURL;
exportSession.outputFileType = #"com.apple.m4a-audio";
exportSession.shouldOptimizeForNetworkUse = YES;
[exportSession exportAsynchronouslyWithCompletionHandler:^{
NSLog (#"i is in your block, exportin. status is %d",
exportSession.status);
switch (exportSession.status)
{
case AVAssetExportSessionStatusFailed:
{
break;
}
case AVAssetExportSessionStatusCompleted:
{
exportSuccess = YES;
if (recorderFilePath)
{
NSError *finalurlError;
[[NSFileManager defaultManager]removeItemAtPath:recorderFilePath error:&finalurlError];
finalurlError = nil;
[[NSFileManager defaultManager]copyItemAtPath:[exportURL path] toPath:recorderFilePath error:&finalurlError];
NSLog(#"finalurlError 2-----%#",finalurlError);
}
[ActivityProgressViewController close];
fileUrl = [NSURL fileURLWithPath:recorderFilePath];
[self updatePlayerForUrl:fileUrl];
break;
}
case AVAssetExportSessionStatusUnknown:
{
break;
}
case AVAssetExportSessionStatusExporting:
{
break;
}
case AVAssetExportSessionStatusCancelled:
{
break;
}
case AVAssetExportSessionStatusWaiting:
{
break;
}
default:
{
NSLog (#"didn't get export status");
break;
}
};
}];
[exportSession release];
}

You're adding your activity indicator to the middle of another view, yes?
If so, you can do this in your show method:
self.superview.userInteractionEnabled = NO;
And in your close method:
self.superview.userInteractionEnabled = YES;
Here is where you'll find information on the UIView's userInteractionEnabled property: http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIView_Class/UIView/UIView.html#//apple_ref/occ/instp/UIView/userInteractionEnabled
Hope this helps!
