动态方法解析：
void method(id self, SEL _cmd, NSString *mes){
NSLog(@"实现方法");
}
+ (BOOL)resolveInstanceMethod:(SEL)sel {
if ([NSStringFromSelector(sel) isEqualToString:@"method"]) {
returnclass_addMethod(self, sel, (IMP)method,"v@:@");
}
return NO;
}
快速转发：
- (id)forwardingTargetForSelector:(SEL)aSelector {
if ([NSStringFromSelector(aSelector) isEqualToString:@"method"]) {
//需要转发的类
return[NewClass new];
}
return [super forwardingTargetForSelector:aSelector];
}
慢速转发：
方法签名：
- (NSMethodSignature *)methodSignatureForSelector:(SEL)aSelector {
if ([NSStringFromSelector(aSelector) isEqualToString:@"method"]) {
return [NSMethodSignature signatureWithObjCTypes:"v@:@"];
}
return [super methodSignatureForSelector:aSelector];
}
消息转发：
- (void)forwardInvocation:(NSInvocation*)anInvocation {
SELsel = [anInvocationselector];
NewClass *newClass = [NewClass new];
if([newClass respondsToSelector:sel]) {
[anInvocationinvokeWithTarget:newClass];
}
[superforwardInvocation:anInvocation];
}
- (void)doesNotRecognizeSelector:(SEL)aSelector {
//防止找不到方法崩溃
NSLog(@"找不到方法");
}
