I am using ABNewPersonViewController to add new contact to the address book. Every thing is fine if I do not add any photo from photo albums. It crashes if I add any photo and here is the log:-
NSInvalidArgumentException', reason: '*** -[NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: UIImagePickerControllerOriginalImage)
What I am doing wrong, or how I can fix this problem
Thanks
This is the code I use:
mNewPersonViewController = [[[ABNewPersonViewController alloc]init]autorelease];
mNewPersonViewController.hidesBottomBarWhenPushed = YES;
mNewPersonViewController.addressBook = app.addressBook;
mNewPersonViewController.newPersonViewDelegate = self;
UINavigationController *presonNavController = [[UINavigationController alloc]initWithRootViewController:mNewPersonViewController];
self.mPopOverController = [[UIPopoverController alloc]initWithContentViewController:presonNavController ];
CGRect frame = [sender frame];
[self.mPopOverController presentPopoverFromRect:frame inView:self.view permittedArrowDirections: UIPopoverArrowDirectionUp animated:YES];
[presonNavController release];
Looks like you are trying to insert a nil value into the dictionary.

In the below code I want to have any identifier to the -firstView- as shown below in the code.
I attempted the following:
//NSLog(#"_[uiviews[0] _description] = %#" , [uiviews[0] _description]);
//NSLog(#"[uiviews[0] nameLabel] = %#" , [uiviews[0] nameLabel]);
//NSLog(#"[uiviews[0] textLabel]= %#" , [[uiviews[0] textLabel].text);
NSString *r = [uiviews[0] textLabel].text;
NSLog(#"[uiviews[0] textLabel]= %#", r);a
But, on activating any of them, the App crashes. Would you please let me know how to have access to the name or any string identifies that UIView.
code
UIView *firstView = uiviews[0];
Use UIView.tag to identify views in your app:
UIView* anotherView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
anotherView.tag = 100;
[view addSubview:anotherView];
UIView* anotherViewAgain = [view viewWithTag:100];
NSLog(#"anotherView and anotherViewAgain are %#the same objects", anotherView == anotherViewAgain ? #"" : #"not "); // prints "anotherView and anotherViewAgain are the same objects"
you can give a try with accessibilityIdentifier of UIView.
uiview tag, is not the best idea (or extend it with enum Int raw value).
with accessibilityIdentifier you can do a lot more logic in nice way.
I've been trying to figure out something that might be obvious and I'm missing the point or losing it. Is something wrong with my toggleStormButtons function that XCode isn't seeing it?
In my main class I have the following to call a function in another class:
STopLeftMenu *mTopLeft = [[STopLeftMenu alloc]init];
[mTopLeft drawStormToggleButton];
Then in the other class I have 2 functions:
- (void)toggleStormButtons{
[UIButton animateWithDuration:0.50 animations:^{
if (stormToggleBtn.transform.tx == 0){
[stormToggleBtn setTransform:CGAffineTransformMakeTranslation(307, 0)];
UIImage* hideButtonImg = [UIImage imageNamed:#"aiga_right_arrow_mod_hide_resize.png"];
[stormToggleBtn setBackgroundImage:hideButtonImg forState:UIControlStateNormal];
}
else{
[stormToggleBtn setTransform:CGAffineTransformMakeTranslation(0, 0)];
UIImage* showButtonImg = [UIImage imageNamed:#"aiga_right_arrow_mod_show_resize.png"];
[stormToggleBtn setBackgroundImage:showButtonImg forState:UIControlStateNormal];
}
}];
for(UIView* storm in stormButtonSaves){
[UIView animateWithDuration:0.50 animations:^{
if (storm.transform.tx == 0){
[storm setTransform:CGAffineTransformMakeTranslation(307, 0)];
storm.alpha = .65;
}
else{
[storm setTransform:CGAffineTransformMakeTranslation(0, 0)];
storm.alpha = 0;
}
}];
}
}
- (void)drawStormToggleButton{
//Storm Pullout Toggle Button
UIImage *buttonImageNormal = [UIImage imageNamed:#"aiga_right_arrow_mod_show_resize.png"];
stormToggleBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 65, 75) ];
[stormToggleBtn setBackgroundImage:buttonImageNormal forState:UIControlStateNormal];
stormToggleBtn.backgroundColor = [UIColor clearColor];
stormToggleBtn.alpha = 0.5;
[stormToggleBtn addTarget:self action:#selector(toggleStormButtons) forControlEvents:UIControlEventTouchUpInside];
[viewsToRemove addObject:stormToggleBtn];
[mv addSubview:stormToggleBtn];
}
I seem to be getting an unrecognized selector message:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSMallocBlock__ toggleStormButtons]: unrecognized selector sent to instance 0x7bc9ca0'

It sounds like your STopLeftMenu is being deallocated too early. The button does not retain its target, so you'll need to keep this object around as long as it needs to respond to the button's messages. If you're not sure how the object is getting deallocated, try debugging with Instruments.
I don't see anything wrong with the code you have shown. I tried it in an existing app of mine and while I had to a) declare a UIButton local variable, b) change the image used for the button and c) comment out the stuff in toggleStormButtons, the method was called every time I tapped the button, no problems.
You don't show your storage for the button. Are you using ARC? Is the button strong? If ARC it should be strong. If not ARC and you are not using a property to assign with a retain, that could cause problems.
What does viewsToRemove do? Looks like an array but it could be something else.
Why don't you use + buttonWithType: and set the frame later?
I am trying to add a UIView to a UITableView's header, then, using the NSLayoutConstraints I want to give it a height.
I've looked through the Apple Docs and the WWDC 2012 videos but I cannot find this particular error anywhere!
I have the following code:
- (UIImageView *)logoImageView
{
if (!_logoImageView) {
_logoImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"logo"]];
[_logoImageView setTranslatesAutoresizingMaskIntoConstraints:NO];
}
return _logoImageView;
}
... in viewDidLoad
UIView *tableHeaderView = [[UIView alloc] init];
tableHeaderView.translatesAutoresizingMaskIntoConstraints = NO;
[tableHeaderView addSubview:self.logoImageView];
[self.tableView setTableHeaderView:tableHeaderView];
NSDictionary *constraintViews = #{#"tableView" : self.tableView, #"tableHeaderView" : tableHeaderView, #"logoImageView" : self.logoImageView};
[self.tableView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"V:[tableHeaderView(50)]"
options:0
metrics:nil
views:constraintViews]];
However when I run it I get the following error:
2012-10-08 16:31:34.559 myApp[6934:c07] *** Assertion failure in -[UITableView layoutSublayersOfLayer:], /SourceCache/UIKit_Sim/UIKit-2372/UIView.m:5776

I had the same exception when I was trying to set the table header view.
When I noticed that the view had Contraints I just unchecked the "Use Autolayout" option from Storyboard.
Screenshot: http://i.stack.imgur.com/5jWHy.png
This solved for me.
The best way to overcome this is to use Interface Builder to setup the UITableView header, then add an Outlet to the height NSLayoutConstraint.
Try this:
logoImageView.translatesAutoresizingMaskIntoConstraints = YES;
(If not works, try to remove:
tableHeaderView.translatesAutoresizingMaskIntoConstraints = NO; //Remove this line
:)
I didn't get any proper solution for this issue but you can fix it by using frames and not setting translatesAutoresizingMaskIntoConstraints property to No (by default its yes, so don't set it)
CGRect headerViewFrame = CGRectMake(0,0,320,60); //Frame for your header/footer view
UIView *tableHeaderView = [[UIView alloc] initWithFrame:headerViewFrame];
tableHeaderView.translatesAutoresizingMaskIntoConstraints = Yes; //Or don't set it at all
[self.tableView setTableHeaderView:tableHeaderView];
I'm trying to make menu with custom font, but it doesn't seem to work.
Here is the code:
- (id) init
{
if (self = [super init])
{
CGSize size = [[CCDirector sharedDirector] winSize];
[CCMenuItemFont setFontName:#"PC Senior Regular"];
[CCMenuItemFont setFontSize:18];
CCMenuItemFont *menu1 = [CCMenuItemFont itemFromString:#"Music ON" target:self selector:#selector(musicToggle)];
CCMenuItemFont *menu2 = [CCMenuItemFont itemFromString:#"Back" target:self selector:#selector(back)];
CCMenu *menu = [CCMenu menuWithItems:menu1, menu2, nil];
[menu setPosition:ccp(size.width / 2 , size.height / 2)];
[menu alignItemsVertically];
[self addChild:menu];
}
Here is the code in my info.plist:
<key>UIAppFonts</key>
<array>
<string>PC Senior Regular.ttf</string>
<string>senior.ttf</string>
</array>
Exception:

I have tried using senior.ttf, just senior, etc.
Both fonts are added as targets for the project. I double checked for correct type case.
What is going wrong?
Have you tried something like this?
CCLabelTTF *label = [CCLabelTTF labelWithString:"Some Text" fontName:#"MyFont.TTF" fontSize:24.0];
CCMenuItem *item = [CCMenuItemLabel itemWithLabel:label target:self selector:#selector(myFunction)];
CCMenu *menu = [CCMenu menuWithItems:item];
[self addChild:menu];
Your info.plist looks right, and this code has worked for me. That said, I do recommend setting breakpoints and trying to find where your error is coming from.
An invalid argument exception means that you are trying to use a method that is not recognized. The problem is your sizeWithZFont method. I have tried to search in the cocos2d documentation and that is not a method in there.
So Instruments tells me I have three memory leaks originating in this method (specifically, it points out the line:
[self.view addSubview:menuBar.view];
I can't see a leak and am racking my brains. I'm keeping a reference to the menuBar object and am releasing it. Anyone smarter than me that can explain? Is it a coincidence that I have three menubar items in my XIB and I'm getting three leaks?
Here is the entire method:
//
root vc calls to toggle display state of menu bar on screen
-(IBAction) showToolBar {
//if no toolbar exists, create one and add it to the view
if (!menuBarView) {
MenuBarViewController *menuBar = [[MenuBarViewController alloc] initWithNibName:#"MenuBarViewController" bundle:nil];
menuBar.book = self.selectedTitleDeck;
menuBar.booksArray = self.allTitleDeck;
self.menuBarView = menuBar;
[self.view addSubview:menuBar.view];
[menuBar release];
}
CGRect frame = menuBarView.view.frame;
[UIView beginAnimations:nil context:NULL];
if (self.toolBarIsDisplayed == NO) {
//show the toolbar
frame.origin.y = 725;
self.toolBarIsDisplayed = YES;
} else if (self.toolBarIsDisplayed == YES) {
//hide the toolbar
frame.origin.y = 788;
self.toolBarIsDisplayed = NO;
}
self.menuBarView.view.frame = frame;
[UIView commitAnimations];
}
addSubview: retains the view passed into it (see the reference). Once you call addSubView, you can release that view, like:
MenuBarViewController *menuBar = [[MenuBarViewController alloc] initWithNibName:#"MenuBarViewController" bundle:nil];
menuBar.book = self.selectedTitleDeck;
menuBar.booksArray = self.allTitleDeck;
self.menuBarView = menuBar;
[self.view addSubview:menuBar.view];
[menuBar.view release];
[menuBar release];
}
Show us what happens in MenuBarViewController's dealloc method. I suspect you are forgetting to release its instance variables.
As suggested in the comments to my question, the problem was not in the code but in running my app in the simulator and trying to detect memory leaks.
When Instruments is run against the code on the device, no leaks are reported.
My consolation prize is a far more profound understanding of memory management unearthed in two days of trying to locate a leak that didn't exist.
Thanks to all for your advice, much appreciated.
