Sharing data between iOS apps

Preparatory work

Two new applications, ProjectA and PROJECTB, respectively.
Then from a contribute data to B

Then set the URL of the PROJECTB schemes

To add a jump URL in projecta:

nsurl *url = [nsurl urlwithstring:@"Projectb:hehe"]; [[uiapplication sharedapplication]  Openurl:url];   
 
   
  
        
  
    
   
        
  
    
   
   
 
   
  

So the argument behind the Projectb:hehe colon is the data we can pass through.

App Status

• b does not start, then B is started. and call the following method.

-(BOOL) Application: (uiapplication *) application didfinishlaunchingwithoptions: (  NsdictionaryNSLog(@"Projectb_start"//Override point for customization after application Launch. return YES;}   
 
   
  
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
   
 
   
  

• At this point B has started, but run in the background, this time will not invoke the method, and will go:

//When an application is opened by another program, this method is called, in which the data transfer between two applications can be implemented -(BOOL) Application: (uiapplication * ) Application OpenURL: (nsurl *) URL sourceapplication: (nsstring *) sourceapplication annotation: ( ID NSLog (@ "%@"NSLog(@"%@"returnYES;}   
 
   
  
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
        
  
    
   
   
 
   
  

is not very simple, then you also hurry to try it!
