IOS 13 出现奔溃，需要在工程里面加入NSObject 的Category
+ (void)load{
SEL originalSelector = @selector(doesNotRecognizeSelector:);
SEL swizzledSelector = @selector(sw_doesNotRecognizeSelector:);
Method originalMethod = class_getClassMethod(self, originalSelector);
Method swizzledMethod = class_getClassMethod(self, swizzledSelector);
if(class_addMethod(self, originalSelector, method_getImplementation(swizzledMethod), method_getTypeEncoding(swizzledMethod))){
class_replaceMethod(self, swizzledSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod));
}else{
method_exchangeImplementations(originalMethod, swizzledMethod);
}
}
+ (void)sw_doesNotRecognizeSelector:(SEL)aSelector{
//处理 _LSDefaults 崩溃问题
if([[self description] isEqualToString:@"_LSDefaults"] && (aSelector == @selector(sharedInstance))){
//冷处理...
return;
}
[self sw_doesNotRecognizeSelector:aSelector];
}
然后在工程内引入该文件，我是放在PCH里面的
答案
项目用到友盟SDK，升级到最新就可以了
