Respect the accessibility setting "Bold Text" on iOS7, when implementing Dynamic Type with a custom font.
Raw
BoldDynamicText
BOOL MTDIsBoldTextEnabled(void) {
static BOOL boldTextEnabled = NO;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
// Hack that checks if the "bold text" flag in the accessibility settings is enabled
UIFont *font = [UIFont preferredFontForTextStyle:UIFontTextStyleBody];
boldTextEnabled = [font.fontName rangeOfString:@"MediumP4"].location != NSNotFound;
});
return boldTextEnabled;
}

Is there any less hacky way to detect this setting? I couldn't figure it out, use at own risk.

dispatch_once might not be a good idea - since that can be changed at runtime as well...

Wouldn't the kernel be patched (https://twitter.com/GlennF/status/400058776738205696) and all apps killed? I think dispatch_once is correct in this instance.

still running iOS 7.0.4, up until then it restarts iOS and the app gets killed. Didn't test it on iOS 7.1 Beta though.
