我不知道发生了什么事,我正在努力解决这个问题,我正在尝试为代码中的不同大小调整类来满足使用IBInspectables的一些特殊情况.
在模拟器上,以下代码在iPad,iPhone 4和iPhone 6上按预期工作.
但是在界面构建器中,只预览任何/任何和常规/常规工作.
这好像是个bug？
或者有没有人对可能有效的替代方法有任何建议？
- (void)drawRect:(CGRect)rect {
// Drawing code
CGFloat l_borderWidth = self.AaBorderWidth; // 8.5
CGFloat l_cornerRadius = self.AaCornerRad; // 33
CGFloat l_shadHeight = self.AaShadHeight; // 15.1
CGFloat l_textYOffset = self.AaTextYOffset; // 6.1
if (self.traitCollection.horizontalSizeClass == UIUserInterfaceSizeClassCompact)
{
if (self.traitCollection.verticalSizeClass == UIUserInterfaceSizeClassCompact)
{
//iphone3.5 / 4 / 4.7 landscape
l_borderWidth = self.CcBorderWidth;
l_cornerRadius = self.CcCornerRad;
l_shadHeight = self.CcShadHeight;
l_textYOffset = self.CcTextYOffset;
}
}
if (self.traitCollection.horizontalSizeClass == UIUserInterfaceSizeClassRegular)
{
if (self.traitCollection.verticalSizeClass == UIUserInterfaceSizeClassRegular)
{
//ipad landscape
l_borderWidth = self.RrBorderWidth;
l_cornerRadius = self.RrCornerRad;
l_shadHeight = self.RrShadHeight;
l_textYOffset = self.RcTextYOffset;
}
if (self.traitCollection.verticalSizeClass == UIUserInterfaceSizeClassCompact)
{
//iphone6+
l_borderWidth = self.RcBorderWidth;
l_cornerRadius = self.RcCornerRad;
l_shadHeight = self.RcShadHeight;
l_textYOffset = self.RcTextYOffset;
}
}
编辑：我也尝试了以下方法
- (void)layoutSubviews
{
[super layoutSubviews];
[self setSizingClassValues];
}
- (void)traitCollectionDidChange:(UITraitCollection *)prevIoUsTraitCollection
{
[super traitCollectionDidChange:prevIoUsTraitCollection];
[self setSizingClassValues];
}
- (void)updateConstraints
{
[self setSizingClassValues];
[super updateConstraints];
}
.
- (instancetype)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame])
{
[self setSizingClassValues];
}
return self;
}
- (void)awakeFromNib
{
[super awakeFromNib];
// Run time,loading from xib.
}
- (void)prepareForInterfaceBuilder
{
[super prepareForInterfaceBuilder];
// Design time.
[self setSizingClassValues];
}
