解决IOS10字体适配问题(上)

解决升级IOS10后由于字体的点数改变导致部分布局出现显示不全(显示为 ... )的情况

首先, 咱们先解决纯代码布局问题,.................

// 核心代码, 是否启用字体重定向, 呵呵!!
#define UseFontManager 1UL

#ifdef UseFontManager
#define SysFont(x)   [UIFont sc_systemFontOfSize:(x)]
#define BoldFont(x)  [UIFont sc_boldSystemFontOfSize:(x)]
#else
#define SysFont(x)   [UIFont systemFontOfSize:(x)]
#define BoldFont(x)  [UIFont boldSystemFontOfSize:(x)]
#endif

@interface UIFont(sma11case_IOS)
+ (instancetype)sc_systemFontOfSize: (CGFloat)fontSize;
+ (instancetype)sc_boldSystemFontOfSize: (CGFloat)fontSize;
@end

static double gs_sysVer = 0.0;

@implementation UIFont(sma11case_IOS)
+ (instancetype)sc_boldSystemFontOfSize: (CGFloat)fontSize
{
    if (!gs_sysVer)
    {
        NSString *ver = [[UIDevice currentDevice].systemVersion regexpFirstMatch:@"^\\d+(\\.\\d+)*"];
        gs_sysVer = atof(ver.UTF8String);
    }
    
    if (gs_sysVer >= 10.0)
    {
        CGFloat p = fontSize * 17 / 17.5;
        MLog(@"convert bold font: %f => %f", fontSize, p);
        fontSize = p;
    }
    
    return [UIFont boldSystemFontOfSize:fontSize];
}

+ (instancetype)sc_systemFontOfSize: (CGFloat)fontSize
{
    if (!gs_sysVer)
    {
        NSString *ver = [[UIDevice currentDevice].systemVersion regexpFirstMatch:@"^\\d+(\\.\\d+)*"];
        gs_sysVer = atof(ver.UTF8String);
    }
    
    if (gs_sysVer >= 10.0)
    {
        CGFloat p = fontSize * 17 / 17.5;
        MLog(@"convert bold font: %f => %f", fontSize, p);
        fontSize = p;
    }
