将图像传递给iOS中的滑块

Question

我制作了一个自定义表格视图，其中有一些标签和图像视图，其中数据来自服务并进一步传递到新视图控制器以获取数据的详细信息。单击单元格时，将来自特定单元格的数据传递给新的vc，并在其中显示其详细信息。当新的vc打开一个叫做服务的服务时，所有的图像都会在新的vc中显示出来。而且我使用了图像滑块来显示来自该滑块中服务的所有图像。我已经使用这个滑块enter link description here，最初我使用了一些静态图像，而不是我将图像数组传递给sider，但我不知道为什么图像没有进入滑块。我的代码是，

-(void)loadCustomerRecords 
{ 

    NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration]; 
    NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]]; 


    NSString *string1 = _propid.text; 

    NSLog(@"ID is %@",string1); 


    NSString *urll=@"My URL"; 

    NSString *string3 = [urll stringByAppendingString:string1]; 

    NSURL * url = [NSURL URLWithString:string3]; 

    NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url]; 


    NSString *parameters = [NSString stringWithFormat:@"%@",@"HI"]; 

    NSLog(@"parameter %@",parameters); 
    [urlRequest setHTTPMethod:@"POST"]; 

    [urlRequest setHTTPBody:[parameters dataUsingEncoding:NSUTF8StringEncoding]]; 

    NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:urlRequest 
                 completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
                  NSLog(@"Response:%@ %@\n", response, error); 
                  if(error == nil) 
                  { 



                   NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error]; 

                   NSLog(@"MY Response %@ ", dictionary); 

                   NSArray *results = [dictionary objectForKey:@"property_images"]; 
                   NSLog(@"RESULT %@ ", results); 

                   for (NSDictionary * oneCustomer in results) 
                   { 
                    // Create a new Customer record 

                    StringData * newCustomer = [[StringData alloc] init]; 


                    newCustomer.images = [oneCustomer objectForKey:@"name"]; 

                    NSLog(@"IMAGE: %@ ", newCustomer.images); 


                    [_Image1 addObject:newCustomer]; 


                    NSString *imageURL = @"http://www.pk.house/frontend/propertyimages/"; 


                    NSString *string3 = [imageURL stringByAppendingString:newCustomer.images]; 

                    newCustomer.images = string3; 

                    NSLog(@"Image URL %@",string3); 


                    // [_Image1 addObject:[oneCustomer objectForKey:@"name"]]; 
                    //NSLog(@"Array %@",_Image1); 

                   } 
                   dispatch_async(dispatch_get_main_queue(), ^{ 
                    // This code will run once the JSON-loading section above has completed. 


                   }); 




                   NSString *status=[dictionary valueForKey:@"property_images"]; 
                   NSLog(@"Status:%@",status); 

                  } 
                  else{ 
                   NSLog(@"network error:"); 


                  } 
                 }]; 
    [dataTask resume]; 

}

你从哪里初始化了_Image1数组？并且您没有将更新后的字符串添加到数组中。

试试这个：

-(void)loadCustomerRecords 
{ 
    NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration]; 
    NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]]; 


NSString *string1 = _propid.text; 

NSLog(@"ID is %@",string1); 


NSString *urll=@"My URL"; 

NSString *string3 = [urll stringByAppendingString:string1]; 

NSURL * url = [NSURL URLWithString:string3]; 

NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url]; 
NSMutableArray *_Image1 = [NSMutableArray new]; 

NSString *parameters = [NSString stringWithFormat:@"%@",@"HI"]; 

NSLog(@"parameter %@",parameters); 
[urlRequest setHTTPMethod:@"POST"]; 

[urlRequest setHTTPBody:[parameters dataUsingEncoding:NSUTF8StringEncoding]]; 

NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) 
{ 
    NSLog(@"Response:%@ %@\n", response, error); 
    if(error == nil) 
    { 
     NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error]; 

     NSLog(@"MY Response %@ ", dictionary); 

     NSArray *results = [dictionary objectForKey:@"property_images"]; 
     NSLog(@"RESULT %@ ", results); 

     for (NSDictionary * oneCustomer in results) 
     { 
      // Create a new Customer record 

      StringData * newCustomer = [[StringData alloc] init]; 

      NSString *imageURL = @"http://www.pk.house/frontend/propertyimages/"; 
      NSString *string3 = [imageURL stringByAppendingString:[oneCustomer objectForKey:@"name"]]; 
      newCustomer.images = string3; 
      [_Image1 addObject:newCustomer]; 

      NSLog(@"Image URL %@",string3); 


      // [_Image1 addObject:[oneCustomer objectForKey:@"name"]]; 
      //NSLog(@"Array %@",_Image1); 

     } 
     dispatch_async(dispatch_get_main_queue(), ^{ 
      // This code will run once the JSON-loading section above has completed. 

      NSLog(@"Array of images :%@",_Image1); 

     }); 




     NSString *status=[dictionary valueForKey:@"property_images"]; 
     NSLog(@"Status:%@",status); 

    } 
    else{ 
     NSLog(@"network error:"); 


    } 


}]; 
    [dataTask resume]; 

}
