I'm getting this error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVAssetWriter initWithURL:fileType:error:] invalid parameter not satisfying: [outputURL isFileURL]'
On this line:
AVAssetWriter * assetWriter = [[AVAssetWriter alloc] initWithURL:videoURL
fileType: AVFileTypeMPEG4
error: &movieError];
Where videoURL logs as:
/var/mobile/Applications/A032EEA6-C83D-49DA-B118-E4E4B9F41C7F/Documents/videoForSegmentNumber1.mp4
the line before this is called.
I've also tested against isFileURL myself and its returning NO. What is required to be a valid fileURL?
Use
+ (id)fileURLWithPath:(NSString *)path
instead of
+ (id)URLWithString:(NSString *)URLString

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];
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
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__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 have the following code:
#try {
NSSet *set = [NSKeyedUnarchiver unarchiveObjectWithData:mData];
}
#catch (NSException *exception) {
// Use default data
}
At some point it seems that I wasn't archiving properly and mData is corrupted.
This gives me the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '*** -[NSKeyedUnarchiver initForReadingWithData:]:
incomprehensible archive (0x14, 0xffffff9a, 0xffffffd0, 0x1d, 0x9, 0x3d, 0x43, 0x3)'

If a try/catch block does not work, how am I supposed to check for an exception here? Shouldn't it be working?
Thank you.
I don't think the try-catch code wasn't working. The log says "uncaught exception" so this error happens somewhere else in your code.
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.
I would like to know why I get an error message
Thread 1: Program received signal: "SIGABRT")
When I use this line of code:
NSScanner *userEntered = [[NSScanner alloc] scannerWithString:temp];
The error is:
2011-04-18 02:06:11.995 XXX[25929:207] -[NSConcreteScanner scannerWithString:]: unrecognized selector sent to instance 0x6816bc0

Thank you.
+scannerWithString is a class method and should be used the following way:
NSScanner *userEntered = [NSScanner scannerWithString:temp];
