Innerhalb eines NSStrings können folgende Specifier genutzt werden:

Specifier – Beschreibung
%@ – String
%% – % Character
%d, %D, %i – Signed 32-bit Integer (int)
%u,%U – unsigned 32-bit integer (unsigned int)
%hi – signed 16-bit Integer (short)
%qi- Signed 64-bit integer (long long)
%qu – Unsigned 64-bit integer (unsigned long long)
%x – Unsigned 32-bit integer (unsigned int), angezeigt als hexadecimal nutzt 0–9 and Buchstaben a–f

%X – Unsigned 32-bit integer (unsigned int), angezeigt als hexadecimal nutzt 0–9 and Großbuchstaben A–F
%qx – Unsigned 64-bit integer (unsigned long long), angezeigt als hexadecimal nutzt 0–9 and Buchstaben a–f
%qX – Unsigned 64-bit integer (unsigned long long), angezeigt als hexadecimal nutzt 0–9 and Großbuchstaben A–F
%o, %O – Unsigned 32-bit integer (unsigned int), oktal
%f – 64-bit floating-point number (double)
%e – 64-bit floating-point number (double), scientific notation nutzt ein kleines e um den Exponenten anzuzeigen
%E – 64-bit floating-point number (double),scientific notation nutzt eingroßes E um den Exponenten anzuzeigen
%g – 64-bit floating-point number (double), printed in the style of %e if the exponent is less than –4 or greater than or equal to the precision, in the style of %f otherwise
%G – 64-bit floating-point number (double), siehe %E wenn der Exponent kleiner –4 or greater than or equal to the precision, in the style of %f otherwise
%c – 8-bit unsigned character (unsigned char), printed by NSLog() as an ASCII character, or, if not an ASCII character, in the octal format \\ddd or the Unicode hexadecimal format \\udddd, where d is a digit
%C – 16-bit Unicode character (unichar), printed by NSLog() as an ASCII character, or, if not an ASCII character, in the octal format \\ddd or the Unicode hexadecimal format \\udddd, where d is a digit
%s – Null-terminated array of 8-bit unsigned characters. %s interprets its input in the system encoding rather than, for example, UTF-8.
%S – Null-terminated array of 16-bit Unicode characters
%p – Void pointer (void *), printed in hexadecimal with the digits 0–9 and lowercase a–f, with a leading 0x
%L – Length modifier specifying that a following a, A, e, E, f, F, g, or G conversion specifier applies to a long double argument
%a – 64-bit floating-point number (double), printed in scientific notation with a leading 0x and one hexadecimal digit before the decimal point using a lowercase p to introduce the exponent
%A – 64-bit floating-point number (double), printed in scientific notation with a leading 0X and one hexadecimal digit before the decimal point using a uppercase P to introduce the exponent
%F – 64-bit floating-point number (double), printed in decimal notation
%z – Length modifier specifying that a following d, i, o, u, x, or X conversion specifier applies to a size_t or the corresponding signed integer type argument
%t – Length modifier specifying that a following d, i, o, u, x, or X conversion specifier applies to a ptrdiff_t or the corresponding unsigned integer type argument
%j – Length modifier specifying that a following d, i, o, u, x, or X conversion specifier applies to a intmax_t or uintmax_t argument
