我正在重构我的代码以使其更易于管理我想创建一个包含可以加载到其他类中的函数的类。导入一类函数头
我创建了一个名为functions的类,将funtions.h导入到我的ViewController类的.h中,将函数.m导入到ViewController.m中,但编译器在调用和崩溃时无法识别hasInternetconnection方法。
我没有完全丧失,为什么我不能在这个类
这里是我的代码中调用这个方法,我曾通过S/O良好的外观和谷歌,我还看不到有什么我做错了
Functions.h
#import <Foundation/Foundation.h>
@interface Functions : NSObject
-(BOOL)hasInternetConection;
@end
Functions.m
#import "Functions.h"
@implementation Functions
-(BOOL)hasInternetConection{
NSURL *url=[NSURL URLWithString:@"www.google.com"];
NSURLRequest *req=[NSMutableURLRequest requestWithURL:url];
NSHTTPURLResponse *res=nil;
[NSURLConnection sendSynchronousRequest:req returningResponse:&res error:NULL];
if (res!=nil) {
return NO;
}else{
return YES;}
}
@end
HomeViewController.h
...
#import <QuartzCore/QuartzCore.h>
#import "multiShotViewController.h"
#import "Functions.h"
...
@interface HomeViewController:{的UIViewController
UIGlossyButton *b;
HomeViewController.m
...
#import "detailsViewController.h"
#import "Functions.h"
#define Kwelome @"welcomeread"
@interface HomeViewController()
@end
@class Functions;
@implementation HomeViewController
@synthesize tripName;
@synthesize databasePath, deathtrail;
@synthesize lampingbtn,deerstalkingbtn,boundarybtn, optionsbtn,shootingbtn;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
self.navigationItem.title = @"Home";
UIColor *backg=[[UIColor alloc]initWithPatternImage:[UIImage imageNamed:@"bgcamo.png"]];
self.view.backgroundColor=backg;
[backg release];
}
return self;
}
...
你要在你的HomeViewcontroller中调用' - (BOOL)hasInternetConection'吗? – Alex
