objective-c - Xcode如何在iPhone应用中将函数从一个类调用到另一个类函数

JewelsSharedController.m：

-(void)GetCountries:(id)sender detailDictionary:(id)details
{
}

我想在RootViewController的函数中调用此函数，例如
RootController.m：

-(void)soapresult
{
    //i want to call ""GetContries "" here..
}

我称这个"soapresult"为

-(void)viewdidLoad
{
    [self soapresult];
}

但是当调用函数时会崩溃

最佳答案

JewelsSharedController.h：

//...
-(void)GetCountries:(id)sender detailDictionary:(id)details;
//...

RootController.m：

#import "JewelsSharedController.h"

//...

-(void)soapresult
{
    JewelsSharedController * jewelsSharedController = [[JewelsSharedController alloc] init];
    [jewelsSharedController GetCountries:yourSender detailDictionary:yourDetails];
    [jewelsSharedController release];
}
