I'm using MBProgress HUD and I don't know what is the problem.
I have a UIButton that shows the HUD.
This is my code:
- (void)showHUD:(id)sender {
HUD = [[MBProgressHUD alloc] initWithView:self.view];
HUD.mode = MBProgressHUDModeCustomView;
[self.view addSubview:HUD];
HUD.delegate = self;
HUD.labelText = #"No Internet Connection...";
HUD.opacity = 0.7;
HUD.customView =
[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"image.png"]];
[HUD showWhileExecuting:#selector(hudWasHidden)
onTarget:self
withObject:nil
animated:YES];
}
- (void)hudWasHidden {
float progress = 0.0f;
while (progress < 1.0f) {
progress += 0.01f;
HUD.progress = progress;
usleep(50000);
}
}
Here is the Console log:

My app always crashes when clicking the UIButton.
Thanks
This is a common crash in Cocoa code: "unrecognized selector" is very explicit in this case. MBProgressHUD doesn't have a customView property, and attempting to set it is causing the crash. The setCustomView is the implicit selector (method) being called here, and Objective-C will crash when a called method isn't there.
Not sure what to tell you about how to accomplish what you're trying to do.

I want to create raw image using UIImagePickerController. I'm doing like this but getting crash on this line uiipc.mediaTypes=#[(NSString *)kUTTypeRawImage]; crash report says:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'No available types for source 1'.
Code here
UIImagePickerController *uiipc = [[UIImagePickerController alloc] init];
uiipc.delegate=self;
uiipc.mediaTypes=[UIImagePickerController availableMediaTypesForSourceType:uiipc.sourceType];
// uiipc.mediaTypes = #[(NSString *)kUTTypeImage];
uiipc.mediaTypes=#[(NSString *)kUTTypeRawImage];// Getting crash here
uiipc.sourceType = UIImagePickerControllerSourceTypeCamera;
uiipc.allowsEditing = YES;
_imgPickViewController=uiipc;
[self presentViewController:_imgPickViewController animated:NO completion:nil];
I have added a custom popup menu to UIWebView instance:
- (void)viewDidLoad
{
UILongPressGestureRecognizer* gesture = [[[UILongPressGestureRecognizer alloc]
initWithTarget:self action:#selector(handleGesture::)] autorelease];
}
- (void)handleGesture
{
}
- (void)handleGesture:(UIGestureRecognizer*)gestureRecognizer
{
if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
[gestureRecognizer.view becomeFirstResponder];
UIMenuController* mc = [UIMenuController sharedMenuController];
[mc setTargetRect: gestureRecognizer.view.frame inView: gestureRecognizer.view.superview];
[mc setMenuVisible: YES animated: YES];
}
And it works! Until I focus textarea (CodeMirror editor) on a webpage. At this case I have the following exception:
-[FirstViewController handleGesture::]: unrecognized selector sent to instance 0x20369c00
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[FirstViewController handleGesture::]: unrecognized selector sent to instance 0x20369c00'

I think it's required to implement undocumented version of handleGesture selector with exotic parameters. Is it right? How to find what kind of parameters is required?
The correct code:
initWithTarget:self action:#selector(handleGesture:)] autorelease];
I am getting the following error:
- (UIView *)carousel:(iCarousel *)carousel placeholderViewAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UILabel *label = nil;
//create new view if no view is available for recycling
if (view == nil)

label = [[UILabel alloc] initWithFrame:view.bounds];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
label.font = [label.font fontWithSize:50.0f];
[view addSubview:label];
}
else
{
label = [[view subviews] lastObject];
}
//set label
label.text = (index == 0)? #"[": #"]";
return view;
}

Any idea?
Well, yes. The error indicates you're passing two parameters (for carousel and placeholderViewAtIndex). However, the method is actually carousel: placeholderViewAtIndex: reusingView:, i.e. taking three parameters. So, just pass one more for reusingView (or nil, as the method has logic to handle this case).
2011-12-01 18:10:36.932 AVCam[3987:17903] *** -[UIImage _isResizable]: message sent to deallocated instance 0xdf7e360
Current language: auto; currently objective-c
The Code is
UIImageView * firstView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 240)];
[firstView setContentMode:UIViewContentModeScaleAspectFill];
firstView.image = firstPhoto.photo;
[firstBlock addSubview:firstView];
[firstView release];
Does anyone know what this means? What could be the cause of it?
Thanks!
The problem should be here:
firstView.image = firstPhoto.photo;
What is firstPhoto? When does it get released? I guess it gets deallocated before it becomes the content of that UIImageView.
You'll probably have to send a `[retain]` message, something like:
firstView.image = [firstPhoto.photo retain];
When trying to show the UIImagePickerController I had strange problems with my app crashing on iOS4. Here's the output from log:
malloc: *** error for object 0x550ba20: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Setting breakpoints, trying to spy the name of the object 0x550ba20 (with print-object) does not work. Enabling zombie detection also does not work. Here is my code:
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
cameraPicker = [[UIImagePickerController alloc] init];
cameraPicker.delegate = self;
cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
// Insert the overlay:
cameraPicker.cameraOverlayView = self.overlay;
self.cameraPicker.delegate = self;
//Hide controls
cameraPicker.showsCameraControls = NO;
cameraPicker.navigationBarHidden = YES;
// Make camera view full screen:
cameraPicker.wantsFullScreenLayout = YES;
cameraPicker.cameraViewTransform = CGAffineTransformScale(self.cameraPicker.cameraViewTransform, 1.0, 1.12412);
[self presentModalViewController:cameraPicker animated:NO];
[cameraPicker release];
Any ideas? Code is executed at the very end of viewDidLoad.
Is cameraPicker a property? You are initializing it first as a local variable and then using it as a property:
cameraPicker.cameraOverlayView = self.overlay;
!!self.!!cameraPicker.delegate = self;
and
cameraPicker.cameraViewTransform = CGAffineTransformScale(!!self.!!cameraPicker.cameraViewTransform, 1.0, 1.12412);
