错误“没有针对选择器的已知类方法Hello：'”在定制的框架 [英] Error "No known class method for selector 'Hello:'" in custom-made framework

问题描述

我为公司制定了一个框架，我已经完成了所有的代码。我现在正试图将其打包成一个框架。作为一个测试，我使用这个名字的方法： - （void）Hello：（NSString *）worldText;

当我尝试在框架使用此代码调用它 [CompanyMobile Hello：@World]; ，我得到一个编译错误， / p>

选择器'Hello：'没有已知的类方法

$ b b

我的框架中的.m如下：

  #importHello.h
 
 @implementation Hello 
 
  - （id）init 
 {
 self = [super init]; 
 if（self）{
 //初始化代码在这里。 
} 
 
 return self; 
} 
 
  - （void）Hello：（NSString *）world {
 
} 
 
 @end 
  
 
 
 
我的框架中的.h如下：
  #import< Foundation / Foundation.h> 
 
 @interface Hello：NSObject 
  - （void）Hello：（NSString *）world; 
 @end 
  
我的申请中的.h 
  //

 // FMWK TEST

您定义 Hello：作为实例方法，但是您要向类发送 Hello：。要定义一个类方法，你写 +（void）Hello：而不是  - （void）Hello： / p> 
I am making a framework for a company and I have completed all the code. I'm now trying to package it into a framework.  As a test I made a method with this name: -(void)Hello:(NSString *)worldText;

When I try to call it in the application with the framework using this code [CompanyMobile Hello:@"World"];, I'm getting a compiler error which says

  
No known class method for selector 'Hello:'  
The .m in my framework is as follows:
#import "Hello.h"

@implementation Hello

- (id)init
{
    self = [super init];
    if (self) {
        // Initialization code here.
    }

    return self;
}

-(void)Hello:(NSString *)world {

}

@end
The .h in my framework is as follows:
#import <Foundation/Foundation.h>

@interface Hello : NSObject
-(void)Hello:(NSString *)world;
@end
The .h in my application
//
//  FMWK_TESTViewController.h
//  FMWK TEST

//

#import <UIKit/UIKit.h>
#import <companyMobile/Hello.h>
@interface FMWK_TESTViewController : UIViewController

@end

#import "FMWK_TESTViewController.h"

@implementation FMWK_TESTViewController

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Release any cached data, images, etc that aren't in use.
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [Badgeville Hello:@"Sam"];
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return YES;
}

@end

解决方案
You defined Hello: as an instance method, but you're sending Hello: to the class. To define a class method, you write + (void)Hello: rather than - (void)Hello:.
