Hi, all
I have a problem with the NSMutableAttributedString's
setBaseWritingDirection method
here is a code
NSMutableAttributedString *attrString = [[[NSAttributedString
alloc] initWithString:textString attributes:stringAttributes]
autorelease];
The above creates an immutable NSAttributedString. The pointer to
that is stored in a variable of type NSMutableAttributedString*, but
that doesn't make it so. Replace the use of "NSAttributedString" in
the above with "NSMutableAttributedString" to do the proper thing.
NSRange attrStringRange = NSMakeRange(0,[[attrString string]
length]);
@try {
[attrString
setBaseWritingDirection:NSWritingDirectionNatural
range:attrStringRange];
} @catch (NSException *exception) {
NSLog(@"main: Caught %@: %@", [exception name],
[exception reason]);
}
I'm getting exception
2008-06-15 16:39:06.465 Gateways[14812:10b] *** -
[NSConcreteAttributedString setBaseWritingDirection:range:]:
unrecognized selector sent to instance 0x10248ab0
NSLog output is
2008-06-15 16:41:48.676 Gateways[14812:10b] main: Caught
NSInvalidArgumentException: *** -[NSConcreteAttributedString
setBaseWritingDirection:range:]: unrecognized selector sent to
instance 0x10248ab0
This exception sort of gives you the hint, if you know what to look
for. The object is of the concrete class
NSConcreateAttributedString, which doesn't indicate that it's
mutable, so you can guess that it isn't.
Cheers,
