ios app全局字体设置

方法一：

写一个UILabel(FontExtension)扩展
重写initWithFrame(手写代码必走方法)和awakeFromNib(xib必走方法)
当然UIButton、UITextView等控件都可以用这种方式
//
// UILabel+FontExtension.h
// FontSet

@interface UILabel (FontExtension)

@end

//
// UILabel+FontExtension.m
// FontSet

#import "UILabel+FontExtension.h"

#define kGlobalFontFamilyName @"Snell Roundhand"       // 全局字体名称

@implementation UILabel (FontExtension)

- (instancetype)initWithFrame:(CGRect)frame
{
    if (self = [super initWithFrame:frame]) {
        [self setGlobalFont];
    }

    return self;
}

- (void)awakeFromNib
{
    [super awakeFromNib];
    [self setGlobalFont];
}

- (void)setGlobalFont
{
    [self setFont:[UIFont fontWithName:kGlobalFontFamilyName size:17]];
}

@end

方法二：

写一个基类(比如FontViewController)继承UIViewController
重写viewWillLayourtSubviews

- (void)viewWillLayoutSubviews
{
    [self setFontFamily:@"Microsoft YaHei" forView:self.view andSubViews:YES];
}

// 遍历self.view 中所有的UILabel设置其字体
- (void)setFontFamily:(NSString*)fontFamily forView:(UIView*)view andSubViews:(BOOL)isSubViews
{
    if ([view isKindOfClass:[UILabel class]])
    {
        UILabel *lbl = (UILabel *)view;
        [lbl setFont:[UIFont fontWithName:fontFamily size:[[lbl font] pointSize]-2]];
    }

    if (isSubViews)
    {
        for (UIView *sview in view.subviews)
        {
            [self setFontFamily:fontFamily forView:sview andSubViews:YES];
        }
    }
}
