xcode - Having trouble installing specific font in an iOS app - incompatible TTF? -

there font files in code repo font nubian , nubian-alt. licensed , paid , need used. cannot use font in ios, , cannot open font font book though font previews ok in finder , identified truetype font.

i started trying add nubian-medium ios app - using key "fonts provided application" in app's info.plist. font did not appear in list generated using:

 (nsstring *familyname in [uifont familynames]) {    (nsstring *fontname in [uifont fontnamesforfamilyname:familyname]) {      nslog(@"%@", fontname);    }  } 

i checked target's "copy bundle resources" build phase, saw font had been added list.

i tried adding font have used in app, "chess-merida-unicode.ttf", check adding font correctly - copied app , added array of fonts provided application, saw appear in "copy bundle resources" list, reported available using above code snippet.

next took @ font in os x - double-clicking open font book font not opened or added. when tried drag nubian fonts font book new collection reported problems files, in tables contained within font file.

selecting fonts , choosing proceed did nothing.

i downloaded trial of third-party app named font agent pro , not load these fonts.

i found sketchy site called fonts.com , downloaded nubian-medium ("ufonts.com_nubian-medium_1_.ttf") - xcode able recognise file.

i checked permissions on these files , made sure rw all, no change.

at point suspect files broken or corrupted in use on web page (that part of project) , works fine. other steps take? can these files added ios project? if there kinds of ttf cannot used in ios project, how can check whether these kind?

step 1: download nubian font : http://www.fontpalace.com/font-download/nubian-thin/

step 2: add font .ttf file in project

step 3: register font application, set fonts provided application key in info.plist file, see screenshot details.

step 4: create label , assign font ,as following

uilabel *lbl = [[uilabel alloc] initwithframe:cgrectmake(0, 0, 200, 50)]; [lbl settext:@"i nubian-thin"]; [lbl setfont:[uifont fontwithname:@"nubian-thin" size:26.0f]];  [self.view addsubview:lbl];
