//通过NSSelectorFromString获取setHighlightsToday方法

SEL selector= NSSelectorFromString(@"setHighlightsToday:");

//创建NSInvocation

NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDatePicker instanceMethodSignatureForSelector:selector]];

BOOL no = NO;

[invocation setSelector:selector];

//setArgument中第一个参数的类picker，第二个参数是SEL，

[invocation setArgument:&no atIndex:2];

//让invocation执行setHighlightsToday方法

[invocation invokeWithTarget:self.datePicker];
