How to use
#include <Lokie/Lokie.h>
//! insert something before UIViewController::viewDidAppear:
Class cls = NSClassFromString(@"UIViewController");
[cls Lokie_hookMemberSelector:@"viewDidAppear:" withBlock:^(id target, BOOL ani){
NSLog(@"LOKIE: before viewDidAppear");
}policy:LokieHookPolicyBefore];
[cls Lokie_hookMemberSelector:@"viewDidAppear:" withBlock:^(id target, BOOL ani){
NSLog(@"LOKIE: after viewDidAppear");
}policy:LokieHookPolicyAfter];
//! we can insert some code before/after
Class cls = NSClassFromString(@"MyViewController");
[cls Lokie_hookMemberSelector:@"initWithConfig:"
withBlock:^(id target, NSDictionary *param){
NSLog(@"%@", param);
NSLog(@"Lokie: %@ is created", target);
} policy:LokieHookPolicyAfter];
//! hooked selector does not has any param
[cls Lokie_hookMemberSelector:@"dealloc" withBlock:^(id target){
NSLog(@"Lokie: %@ is dealloc", target);
} policy:LokieHookPolicyBefore];
