UINavigationController上的pushViewController和showViewController方法有什么区别？

我有一个带有2个架构片的胖静态库(armv7,arm64).我正在尝试使用swift并将其包装到Cocoa Touch Framework中.

我所做的:

1. 创建Cocoa Touch Framework项目
2. 使用标题拖动.a静态库
3. 设置OTHER_LDFLAGS为-all_load
4. 设置ONLY_ACTIVE_ARCH为NO
5. 设置VALID_ARCHS并ARCHS以armv7和arm64
6. 使用Release构建配置构建
7. 从DerivedData获取.framework文件/../../产品/

当我把这个.framework放到我的swift项目中时,在我的目标常规设置中添加嵌入式二进制文件部分,导入框架并使用其中一个类,我得到undefined symbols for architecture arm64或者undefined symbols for architecture armv7.

编辑:
不确定它是否有帮助,但我注意到静态库的大小约为34MB,但生成的.framework的大小约为12MB.

编辑2:
我nm -arch arm64 -g myLibraryName在静态库和生成的动态库上运行.动态库不包含静态库具有的所有符号.看起来像XCode构建过程剥离了很多.

我正在尝试整合新的GoogleMaps sdk 1.10.1,然后我从https://developers.google.com/maps/documentation/ios/start快速入门

但我收到以下错误,我遇到了重复的符号错误.

我有一个UITableViewCell包含一些UILabel,我希望这个标签水平填充的宽度,UITableViewCell并不是大空间而不是其他,这是一个例子:

|---------------------------------------------------------
|                                                        |
|***This is a uilabel***This is a uilabel***label***lb** |
|                                                        |
|---------------------------------------------------------

因此,对于不同的UILabel宽度我希望所有UILabel填充所有UITableViewCell固定字体大小,如果需要,*是间距,我如何通过自动布局实现这一点？

我在这个博客上发现了这个代码http://themainthread.com/blog/2014/02/building-a-universal-app.html

static void initSimpleView(SimpleView *self) {
    // Configure default properties of your view and initialize any subviews
    self.backgroundColor = [UIColor clearColor];

    self.imageView = ({
        UIImageView *imageView = [[UIImageView alloc] init];
        imageView.translatesAutoresizingMaskIntoConstraints = NO;
        [self addSubview:imageView];
        imageView;
    });

    self.label = ({
        UILabel *label = [[UILabel alloc] init];
        label.translatesAutoresizingMaskIntoConstraints = NO;
        [self addSubview:label];
        label;
    });
}

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        initSimpleView(self);
    }
    return self;
}

它是如何工作的？是什么意思static void initWithSimpleView(SimpleView *self)？为什么imageView和label在某种块的初始化？
