IOS源码封装成.bundle和.a文件时,使用单例作为出口的写法!任何封装都建议使用这种方法作为出口

头文件

以此作为模板,记录于此

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
//this can write delegate directly,but out of the class ,can't see the class,so we add a @class
@class HWeatherManager;

@protocol HWeatherManagerDelegate <NSObject>

//use the delegate pass by value
-(void)test:(NSString *)str;

@end

@interface HWeatherManager : NSObject

@property (nonatomic,strong)UIViewController <HWeatherManagerDelegate> * delegate;
+(HWeatherManager *)defaultManager;

-(void)start;
-(void)endWeather;
@end
实现部分

#import "HWeatherManager.h"
#import "HWeatherViewController.h"

@implementation HWeatherManager

+(HWeatherManager *)defaultManager
{
    static HWeatherManager *manager=Nil;
    @synchronized(self)
    {
        if (manager==Nil) {
            manager=[[HWeatherManager alloc]init];
            [HWeatherViewController class];
        }
    }
    return manager;
}

-(void)start
{
   // [self.delegate test:@"hello"];
     NSBundle *bundle=[NSBundle bundleWithURL:[[NSBundle mainBundle]URLForResource:@"HWeatherDataLibResources" withExtension:@"bundle"]];
    UIStoryboard *storyboard=[UIStoryboard storyboardWithName:@"WeatherStoryboard" bundle:bundle];
    // NSLog(@"－－%@",navigation);
    [self.delegate presentViewController:[storyboard instantiateInitialViewController] animated:YES completion:^{

    }];

}

-(void)endWeather
{
    UIStoryboard *storyboard=[UIStoryboard storyboardWithName:@"Main" bundle:Nil];
    [self.delegate presentViewController:[storyboard instantiateViewControllerWithIdentifier:@"endWeather"] animated:YES completion:^{

    }];

}

@end
