在Instagram上进行类转储(v7.7)时,我很困惑为什么在这个类中," sponsContext"的方法声明。不见了。相比之下,IDA显示&#34 ;-(char)赞助的上下文"方法
类转储结果:
@interface IGFeedItemTimelineLayoutAttributes : XXUnknownSuperclass {
BOOL _sponsoredContext;
BOOL _showExploreContext;
BOOL _showTimeStampOnFirstLayoutElement;
IGFeedItem* _feedItem;
NSArray* _rowItems;
}
@property(retain, nonatomic) NSArray* rowItems;
@property(assign, nonatomic) BOOL showTimeStampOnFirstLayoutElement;
@property(assign, nonatomic) BOOL showExploreContext;
@property(assign, nonatomic) BOOL sponsoredContext;
@property(retain, nonatomic) IGFeedItem* feedItem;
-(void).cxx_destruct;
-(id)commentForTextTimelineRow:(int)textTimelineRow;
-(int)cellTypeForTextTimelineRow:(int)textTimelineRow;
-(int)numberOfTextRowsInTimeline;
-(id)initWithFeedItem:(id)feedItem sponsoredContext:(BOOL)context showExploreContext:(BOOL)context3 showTimeStampOnFirstLayoutElement:(BOOL)element;
@end
IDA结果:
IGFeedItemTimelineLayoutAttributes - (char)sponsoredContext
char __cdecl -[IGFeedItemTimelineLayoutAttributes sponsoredContext](struct IGFeedItemTimelineLayoutAttributes *self, SEL)
__IGFeedItemTimelineLayoutAttributes_sponsoredContext_
MOV R1, #(_OBJC_IVAR_$_IGFeedItemTimelineLayoutAttributes._sponsoredContext - 0x15C64)
ADD R1, PC
LDR R1, [R1]
LDRSB R0, [R0,R1]
BX LR
End of function -[IGFeedItemTimelineLayoutAttributes sponsoredContext]
此外,当我尝试使用Logos挂钩此方法时:
%hook IGFeedItemTimelineLayoutAttributes
-(BOOL)sponsoredContext{
NSLog(@"Text:%d", %orig());
return %orig();
}
%end
Cydia Substrate给我错误:
MS:Warning: message not found [IGFeedItemTimelineLayoutAttributes sponsoredContext:]
如何挂钩此方法?为什么没有类转储显示它,但IDA呢?这个方法有什么特别之处?
提前致谢。
