MPTidbits 1.0

A set of very small categories for NSString, NSMutableString, NSArray, and NSDictionary that add a few sorely lacking features (isEmpty and containsKey: methods, for instance). <br /><br />These functions can be found in MPFunctions.h.<br /> . NSString *MPHexStringFromBytes(void *bytes, NSUInteger len)<br /><br /> . Returns a hexadecimal NSString representation of the data referenced by bytes. len should be the length of the data (the number of bytes).<br /><br />NSString Methods<br />These methods can be found in NSString+MPTidbits.h.<br /> - (BOOL)isEmpty<br /> Returns YES only if the receiver is either empty (no characters), or contains only whitespace characters.<br /><br /> - (BOOL)isEmptyIgnoringWhitespace:(BOOL)ignoreWhitespace<br /> If ignoreWhitespace is YES, returns YES only if the receiver is either empty (no characters), or contains only whitespace characters. If ignoreWhitespace is NO, returns YES only if the receiver is empty (no characters) -- it does not ignore whitespace characters.<br /><br /> - (NSString *)stringByTrimmingWhitespace<br /> Returns an NSString object identical to the receiver except that any leading or trailing whitespace characters (the characters in the set returned by NSCharacterSet's +whitespaceCharacterSet) will be stripped.<br /><br /> - (NSString *)MD5Hash<br /> Returns an NSString object that contains a 32-character hexadecimal representation of the receiver's MD5 hash. This method uses the functions of Foundation's CommonCrypto library, which means that your project does not have to link against an outside library (eg, OpenSSL).<br /><br /> - (NSString *)SHA1Hash<br /> Returns an NSString object that contains a 40-character hexadecimal representation of the receiver's SHA-1 hash. This method uses the functions of Foundation's CommonCrypto library, which means that your project does not have to link against an outside library (eg, OpenSSL).<br /><br />NSMutableString Methods<br />These methods can be found in NSString+MPTidbits.h.<br /> - (void)trimCharactersInSet:(NSCharacterSet *)aCharacterSet<br /> Strips leading and trailing characters from the receiver that belong to aCharacterSet. In contrast to NSString's -stringByTrimmingCharactersInSet:, this method operates on the receiver in place.<br /><br /> - (void)trimWhitespace<br /> Strips leading and trailing whitespace characters (the characters in the set returned by NSCharacterSet's +whitespaceCharacterSet) from the receiver. In contrast to the above -stringByTrimmingWhitespace, this method operates on the receiver in place.<br /><br />NSArray Methods<br /><br />These methods can be found in NSCollections+MPTidbits.h.<br /> - (BOOL)isEmpty<br /><br /> Returns YES only if the receiver contains no objects: the equivalent of ([receiver count] == 0).<br /><br />NSDictionary Methods<br /><br />These methods can be found in NSCollections+MPTidbits.h.<br /> - (BOOL)isEmpty<br /><br /> Returns YES only if the receiver contains no objects: the equivalent of ([receiver count] == 0).<br /><br /> - (BOOL)containsKey:(NSString *)aKey<br /><br /> Returns YES only if the key aKey has an associated object in the receiver.<br /> - (BOOL)containsKey:(NSString *)aKey allowEmptyValue:(BOOL)allowEmpty<br /><br /> If allowEmpty is YES, returns YES only if the key aKey has an associated object in the receiver. If allowEmpty is NO, returns YES only if the key aKey has an associated object in the receiver, and that object is neither the NSNull object, nor does it return YES to an isEmpty message (if the object responds to it). This method is useful if you want to quickly check if a key both exists, and is not an empty string, for example.<br />
