I am adding a UILabel instance as a subview of my custom UITableViewCell

When I select the cell, the row is highlighted blue, except for the background
of the label. The label text is sharp, but the background is white for the

Should I be using a different predicate to retrieve Book objects with
the names "myPrefix-v1" and "myPrefix-v2"?

I am having trouble fetching results with a to-many relationship and
would like to ask for advice.
I have two NSManagedObject subclasses: Owner and Book. There is a one-
to-many relationship between Owner and Book (an Owner can be
associated with many Books).

Let's say I have a class interface and implementation, as follows:
---
@interface A : NSObject {
...
}
- (void) handleTask;
@end
@implementation A

- (void) handleTask {
// do stuff specific to A object type...
}

Let's say I then subclass A and override -handleTask:

I have the following method, which digests a string with the SHA-1
algorithm:
- (NSString *) HMACSHA1DigestWithSecretKey:(NSString *)secretKey {
unsigned char digest[CC_SHA1_DIGEST_LENGTH];
char *keyCharPtr = strdup([secretKey UTF8String]);
char *dataCharPtr = strdup([self UTF8String]);
I am trying to use the HMAC SHA-1 components of Apple's CommonCrypto
library with NSStrings, and I am running into some difficulty.
I have the following method:
- (NSString *) hmacSha1:(NSString *)key data:(NSString *)data
{
unsigned char digest[CC_SHA1_DIGEST_LENGTH] = {0};

Thanks for the quick response. Unfortunately, this did not work. The

Is it possible to take a CGLayer and turn it into a bitmap
representation?
Also, is it possible to grab a CGRect "subset" of a CGLayer and append
that to a new CGLayer, so that it isn't necessary to recalculate the
entirety of a new CGLayer?
Thanks,

Thanks for the tip. So I ended up going the route of making my .m files into

The correct type modifier for unsigned integers is %u not %d. Switch

I'm wondering if I'm using unsigned integers (specifically NSUInteger)
properly or not.
I was under the impression that unsigned integers run from 0 to
MAX_INT, but when I use them in a "for" loop within these bounds, the
loop does not seem to always obey these constraints.
For example:
I am currently putting 320 to 480 character long NSString * instances
into an NSMutableArray. The characters are 0 or 1.
I guess I could use an int array, but I'm looking to speed up my app
and reduce storage. Is it possible to create a BOOL array that can be
put into an NSMutableArray?
