xcode版本是：12.4
macos版本：10.15.7
Tweak.mk代码如下：
%hook NSURLProtocol
+(id)propertyForKey:(NSString *)key inRequest:(id)inRequest
{
if([key isEqualToString:@“networkRedirectCount”])
{
return @1;
}
return %orig;
}
%end
Makefile文件如下：
THEOS_DEVICE_IP = 172.18.253.190
THEOS_DEVICE_PORT = 22
TARGET := iphone:clang:latest:7.0
include $(THEOS)/makefiles/common.mk
TWEAK_NAME = gd
gd_FILES = Tweak.xm
gd_CFLAGS = -fobjc-arc
include $(THEOS_MAKE_PATH)/tweak.mk
恳请大佬解答，不胜感激
