代理整理

1、
#pragma mark 回调代理

@protocol getOrgFunctionsDelegate < NSObject >

//加上此句，不强制要求实现

@optional 

- ( void )call_back_getOrgFunctionsWithResult:( NSDictionary *)result;

@end

2、

@property ( nonatomic , retain ) id < getOrgFunctionsDelegate > delegate;

3、

@synthesize delegate;

if ( delegate != nil && [ delegate respondsToSelector : @selector (call_back_applyForOrgWithResult:)]) {

    [ self . delegate call_back_applyForOrgWithResult :jsonDic];

        }
