目标C中的插入符号

^符号在Objective-C中意味着什么？

码:

 GreeRequestServicePopup* requestPopup = [GreeRequestServicePopup popup];
 requestPopup.parameters = parameters;

 requestPopup.willLaunchBlock = ^(id aSender) {
 [[NSNotificationCenter defaultCenter] postNotificationName:@"request_service_popup_will_launch_block" object:nil];

 };

 requestPopup.didLaunchBlock = ^(id aSender) {
[[NSNotificationCenter defaultCenter] postNotificationName:@"request_service_popup_did_launch_block" object:nil];
 };

 requestPopup.willDismissBlock = ^(id aSender) {
 [[NSNotificationCenter defaultCenter] postNotificationName:@"request_service_popup_will_dismiss_block" object:nil];
 };

 requestPopup.didDismissBlock = ^(id aSender) {
 [[NSNotificationCenter defaultCenter] postNotificationName:@"request_service_popup_did_dismiss_block" object:nil];
 };

 requestPopup.cancelBlock = ^(id aSender) {
 [[NSNotificationCenter defaultCenter] postNotificationName:@"request_service_popup_cancel_block" object:nil];
 };

 requestPopup.completeBlock = ^(id aSender) {
 [[NSNotificationCenter defaultCenter] postNotificationName:@"request_service_popup_complete_block" object:nil];
 };

 [self.navigationController showGreePopup:requestPopup];
 }
