For manipulating NSStrings.
Calculates an md5 hash of the string using CC_MD5.
Treats the string as UTF8.
Calculates a sha1 hash of the string using CC_SHA1.
Treats the string as UTF8.
Returns a Boolean value indicating whether the string is a NSString object that contains only whitespace and newlines.
Compares two strings expressing software versions.
The comparison is (except for the development version provisions noted below) lexicographic string comparison. So as long as the strings being compared use consistent version formats, a variety of schemes are supported. For example "3.02" < "3.03" and "3.0.2" < "3.0.3". If you mix such schemes, like trying to compare "3.02" and "3.0.3", the result may not be what you expect.
Development versions are also supported by adding an "a" character and more version info after it. For example "3.0a1" or "3.01a4". The way these are handled is as follows: if the parts before the "a" are different, the parts after the "a" are ignored. If the parts before the "a" are identical, the result of the comparison is the result of NUMERICALLY comparing the parts after the "a". If the part after the "a" is empty, it is treated as if it were "0". If one string has an "a" and the other does not (e.g. "3.0" and "3.0a1") the one without the "a" is newer.
Examples (?? means undefined):
"3.0" = "3.0" "3.0a2" = "3.0a2" "3.0" > "2.5" "3.1" > "3.0" "3.0a1" < "3.0" "3.0a1" < "3.0a4" "3.0a2" < "3.0a19" <-- numeric, not lexicographic "3.0a" < "3.0a1" "3.02" < "3.03" "3.0.2" < "3.0.3" "3.00" ?? "3.0" "3.02" ?? "3.0.3" "3.02" ?? "3.0.2"
Parses a URL query string into a dictionary where the values are arrays.
A query string is one that looks like ¶m1=value1¶m2=value2...
The resulting NSDictionary will contain keys for each parameter name present in the query. The value for each key will be an NSArray which may be empty if the key is simply present in the query. Otherwise each object in the array with be an NSString corresponding to a value in the query for that parameter.
Returns a string that has been escaped for use as a URL parameter.
Appends a dictionary of query parameters to a string, adding the ? character if necessary.
