I have the following code:
UIFont * applicationBolFontOfSize26=[fontsSuperclass returnApplicationMainFontOfSize:26.0f];
[self.settingsButton setTitleTextAttributes:#{ NSFontAttributeName : applicationBolFontOfSize26 } forState:UIControlStateNormal];
where font superclass method is defined as:
+(UIFont *)returnApplicationMainFontOfSize:(CGFloat)floatSize {
return [UIFont fontWithName:#"HelveticaNeue-Regular" size:floatSize];
}
but the self.settingButton setTitleText... crashes with error:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]'
Why?
There is no font named "HelveticaNeue-Regular" so your font is nil. Use [UIFont fontWithName:#"HelveticaNeue" size:floatSize] for the regular Helvetica Neue font.

The object text that you are passing in needs to be an NSString but it is a Message object.
I'm guessing that wherever you are calling this from you are doing something like...
[someObject sizeOfLabel:myLabel withText:message];
When in fact what you meant is...
[someObject sizeOfLabel:myLabel withText:message.text];

Okay there is indeed an actual XIB named BGCinemaScheduleCell
I got this error here:
-(void) vLoadMainBundle
{
if ([self class] == [BGBaseTableViewCell class])
{
return;
}
NSString * className = NSStringFromClass([self class]);
[[NSBundle mainBundle] loadNibNamed:className owner:self options:nil];
}
I have no idea what NSInternalInconsistencyException mean. the value of className is loadNibNamed
It turns out the xib hasn't been copied to the bundle resources that an answer in https://stackoverflow.com/a/5646337/2027232 would work.
The next question would be why the xib isn't copied to the bundle resources when I created it.
Objective C gives me a run-time error for the indicated line of code
-(void) play: (int)i at: (int)j {
if ([self.board[i][j] isEqualToString:#""]){
if (xplays) {
self.board[i][j] = #"x"; //<-----HERE
}
else
self.board[i][j] = #"x";
}
xplays = !xplays;
}
board is a property. The error message is
[__NSArrayI replaceObjectAtIndex:withObject:]: unrecognized selector sent to instance 0x7123120

Do I need to use C-arrays for this kind of assignment?
You should be using an NSMutableArray.
I am trying to use KTPhotoBrowser to use its thumbnail view capabilities. I have some difficulties to push to the viewController that was derived from KTThumbsViewController. It seems the navigationController can only push to UIViewController:
- (void)showSDWebImageSample
{
KTThumbsViewController *newController = [[KTThumbsViewController alloc] init];
[self.navigationController pushViewController:newController animated:YES];
}
and the header file for KTThumbsViewController includes:
#interface KTThumbsViewController : UIViewController <KTThumbsViewDataSource>
I grabbed the code from the provided sample. But it gives me the following runtime error:
-[KTThumbsViewController copyWithZone:]: unrecognized selector sent to instance 0x8877130
2012-10-30 14:52:03.004 myCases_MD[36941:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[KTThumbsViewController copyWithZone:]: unrecognized selector sent to instance 0x8877130'
Could anyone help me please?
Cheers,
I get an error every time I try to store data into the keychain
The error comes from the dictionaryToSecItemFormat method at these lines
NSString *passwordString = [dictionaryToConvert objectForKey:(id)kSecValueData];
[returnDictionary setObject:[passwordString dataUsingEncoding:NSUTF8StringEncoding] forKey:(id)kSecValueData]'
The error is
I'm calling the KeychainItemWrapper methods like this
KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:#"credentials" accessGroup:nil];
[keychain setObject:username forKey:kSecAttrAccount];
[keychain release];
The error is
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
'-[NSConcreteData dataUsingEncoding:]: unrecognized selector sent to instance"
dataUsingEncoding is a method from the NSString class, make username a NSString.
