How to hook Apple's `os_log_with_type` method in Objective-C - ios

Question

I want to hook "React Native" RCTLog logs method _RCTLogJavaScriptInternal , The source codes is:
void _RCTLogJavaScriptInternal(RCTLogLevel level, NSString *message)
{
RCTLogFunction logFunction = RCTGetLocalLogFunction();
BOOL log = RCT_DEBUG || (logFunction != nil);
if (log && level >= RCTGetLogThreshold()) {
if (logFunction) {
logFunction(level, RCTLogSourceJavaScript, nil, nil, message);
}
}
}
RCTLogFunction RCTDefaultLogFunction =
^(RCTLogLevel level,
RCTLogSource source,
__unused NSString *fileName,
__unused NSNumber *lineNumber,
NSString *message) {
os_log_with_type(RCTLogForLogSource(source), RCTLogTypeForLogLevel(level), "%{public}s", message.UTF8String);
};
So if I just hook Apple's os_log_with_type, I will get the RCTLog logs.
This is my codes, but not working. Please help me. Thanks!!!!
#import <os/log.h>
#import "fishhook.h"
static void (*original_oslog)((os_log_t log, os_log_type_t type, const char *format, ...));
void hook_oslog(os_log_t log, os_log_type_t type, const char *format, ...) {
NSLog(#"hook success!");
}
+ (void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
struct rebinding oslog_rebinding = { "os_log_with_type", hook_oslog, (void *)&original_oslog };
rebind_symbols((struct rebinding[1]){oslog_rebinding}, 1);
});
}

Final, I found solution. Not need to hook, Related API have been provided by React Native already.
RCTSetLogFunction(^(RCTLogLevel level, RCTLogSource source, NSString *fileName, NSNumber *lineNumber, NSString *message) {
NSLog(#"%#", message);
});
