Why run the red line of code that prompts:
error: address doesn't contain a section that points to a section in a object file
Reply:
Because that MobileInstallationBrowse just a function pointer, can not be directly used to point to a function that implements
Plus realized on OK

 

int (* MobileInstallationBrowse) (NSDictionary * options, int (* callback) (NSDictionary * dict, id value), id value); 

 int MobileInstallationBrowseImplementation (NSDictionary * options, int (* callback) (NSDictionary * dict, id value), id value) 
{
NSLog (@ "MobileInstallationBrowseImplementation"); 
return 0; 
}  

static int callback (NSDictionary * dict, id result) 
{
NSArray * currentlist = [dict objectForKey: @ "CurrentList"]; 
if (currentlist) 
{
for (NSDictionary * appinfo in currentlist) 
{
[(NSMutableArray *) result addObject: [appinfo copy]]; 
} 
} 
return 0; 
} 

- (Void) btnGetApp 
{
NSMutableArray * result = [NSMutableArray new]; 
MobileInstallationBrowse = MobileInstallationBrowseImplementation; 

MobileInstallationBrowse ([NSDictionary dictionaryWithObject: @ "Any" forKey: @ "ApplicationType"], callback, result); / / Any representative of all programs, where you can use the "System" "User" to distinguish between systems and common software

Halo, made a mistake, look at the red piece of code

int (* MobileInstallationBrowse) (NSDictionary * options, int (* callback) (NSDictionary * dict, id value), id value);

int MobileInstallationBrowseImplementation (NSDictionary * options, int (* callback) (NSDictionary * dict, id value), id value)
{
NSLog (@ "MobileInstallationBrowseImplementation");
return 0;
}
