昨天,我下载了麻雀邮件应用程序,启动后立即崩溃。
生成以下崩溃日志:

问题是 UINavigationBar 中的属性“shadowImage”,它在 iOS 5 上不存在。
现在我正在尝试构建一个移动基板插件以避免崩溃,将缺失的属性添加到 UINavigationBar 并覆盖和以下代码:
#import <Foundation/Foundation.h>
@interface UINavigationBar(MyNavigationBar)
@property(nonatomic,retain) UIImage *shadowImage NS_AVAILABLE_IOS(6_0) UI_APPEARANCE_SELECTOR;
@end
%hook UINavigationBar
- (void)setShadowImage:(UIImage *)shadowImage forToolbarPosition:(id)topOrBottom {
%log;
//%orig;
}
- (void)setShadowImage:(UIImage *)shadowImage {
%log;
//%orig;
}
%end;
我不知道要正确设置 shadowImage 或 UI_APPEARANCE_SELECTOR。
有任何想法吗?谢谢
