你可以嘗試\u1D47（ᵇ）如果字體支持。

請注意，在Unicode中，這不是真正的「上標b」，而是一個注音符號。找到合適解決方案的富文本標籤庫。

a = ᵃ = \u1d43 (modifier letter small a) 
b = ᵇ = \u1d47 (modifier letter small b) 
c = ᶜ = \u1d9c (modifier letter small c) 
d = ᵈ = \u1d48 (modifier letter small d) 
e = ᵉ = \u1d49 (modifier letter small e) 
f = ᶠ = \u1da0 (modifier letter small f) 
g = ᵍ = \u1d4d (modifier letter small g) 
h = ʰ = \u02b0 (modifier letter small h) 
i = ⁱ = \u2071 (superscript latin small letter i) 
j = ʲ = \u02b2 (modifier letter small j) 
k = ᵏ = \u1d4f (modifier letter small k) 
l = ˡ = \u02e1 (modifier letter small l) 
m = ᵐ = \u1d50 (modifier letter small m) 
n = ⁿ = \u207f (superscript latin small letter n) 
o = ᵒ = \u1d52 (modifier letter small o) 
p = ᵖ = \u1d56 (modifier letter small p) 
q = n/a 
r = ʳ = \u02b3 (modifier letter small r) 
s = ˢ = \u02e2 (modifier letter small s) 
t = ᵗ = \u1d57 (modifier letter small t) 
u = ᵘ = \u1d58 (modifier letter small u) 
v = ᵛ = \u1d5b (modifier letter small v) 
w = ʷ = \u02b7 (modifier letter small w) 
x = ˣ = \u02e3 (modifier letter small x) 
y = ʸ = \u02b8 (modifier letter small y) 
z = ᶻ = \u1dbb (modifier letter small z)

您可以在文本字符串中使用HTML標記<sup>，然後讓它使用NSAttributedString-Additions-for-HTML可以從github上顯示的做到這一點。
