Is there a way to change default font for your application

As I understand all standard controls use system font by default.

Also, API [UIFont systemFontOfSize: ] uses system font too.

Is there a way to redefine it for the whole application, instead of setting a font for table, labels and so on?

Define and export (by including a header in files or in precompiled header) a category of UIFont as following:

@implementation UIFont (Utils)

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-protocol-method-implementation"

+ (UIFont *)systemFontOfSize:(CGFloat)size
{
    return [UIFont fontWithName:@"YOUR_TRUETYPE_FONT_NAME_HERE" size:size];
}

+ (UIFont *)lightSystemFontOfSize:(CGFloat)size
{
    return [UIFont fontWithName:@"YOUR_TRUETYPE_FONT_NAME_HERE" size:size];
}

+ (UIFont *)boldSystemFontOfSize:(CGFloat)size
{
    return [UIFont fontWithName:@"YOUR_TRUETYPE_FONT_NAME_HERE" size:size];
}

+ (UIFont *)preferredFontForTextStyle:(NSString *)style
{
    if ([style isEqualToString:UIFontTextStyleBody])
        return [UIFont systemFontOfSize:17];
    if ([style isEqualToString:UIFontTextStyleHeadline])
        return [UIFont boldSystemFontOfSize:17];
    if ([style isEqualToString:UIFontTextStyleSubheadline])
        return [UIFont systemFontOfSize:15];
    if ([style isEqualToString:UIFontTextStyleFootnote])
        return [UIFont systemFontOfSize:13];
    if ([style isEqualToString:UIFontTextStyleCaption1])
        return [UIFont systemFontOfSize:12];
    if ([style isEqualToString:UIFontTextStyleCaption2])
        return [UIFont systemFontOfSize:11];
    return [UIFont systemFontOfSize:17];
}

#pragma clang diagnostic pop

@end

Light variant comes as a useful extra starting with iOS 7. Enjoy! ;)

The answer is no, you cant change apple's systemFont, you need to set the font on your control yourself.

For best way to set a default font for whole iOS app, please check the below SO questions:
