iOS design mode-block implementation of proxy logic

On the A page, click Jump to B page, b page finished, go back to a page, and refresh the content of a page. A typical example is in a list, click Add, jump to the new page, add up, send the data back to the list page, and refresh the contents of the list page.

This, I usually through the agent to achieve, the following try to achieve through the block.

block is defined on page b for Call to a page .

1 /* * 2 *  Confirm Order selection return block3  */ 4 void (^ selectedaddressblock) (Hgaddressmodel * address);

b page, operation completed, to block callback value

1 /**2 * Select the line, in order to confirm the order, choose the delivery address to use3  */4- (void) TableView: (UITableView *) TableView Didselectrowatindexpath: (Nsindexpath *) Indexpath5 {6Hgaddressmodel *entity =Self.datasource[indexpath.row];7     if(self.selectedaddressblock) {8 Self.selectedaddressblock (entity);9     }Ten [Self.navigationcontroller Popviewcontrolleranimated:yes]; One}

A page operation is very simple, jump to the B page, directly call the Block B page we can get the results.

1- (void) Jumpaddress: (UIButton *) Sender {2Addresslistviewcontroller *address =[[Addresslistviewcontroller alloc] init];3address.hidesbottombarwhenpushed =YES;4Address.title =@"Address Management";5Address.selectedaddressblock = ^ (Hgaddressmodel *model) {6Dr_nslog (@"----------model------------%@", model.province_name);7     };8 [Self.navigationcontroller pushviewcontroller:address animated:yes];9}

OK, Finish.
