Question

我正在努力让我的应用程序在WatchKit上工作。我使用Parse，只想显示＆＃34; Request＆＃34;的值。在我的PFObject中作为WatchKit表中的一行。我有表和行设置，行NSObject类只有一个标签，其中＆＃34;请求＆＃34;字段将填充。以下是我在Watch的InterfaceController中所拥有的内容。

#import "InterfaceController.h"
#import "TheTable.h"
#import <Parse/Parse.h>
#import "BlogView.h"
@interface InterfaceController()
@property (nonatomic, retain) PFObject *theObject;
@property (nonatomic, retain)     NSMutableArray *rowTypesList;

@end


@implementation InterfaceController
- (void)awakeWithContext:(id)context {
    [Parse setApplicationId:@"MYID"
                  clientKey:@"MYKEY"];

    [super awakeWithContext:context];

    // Configure interface objects here.
}

- (void)willActivate
{
    PFQuery *query = [PFQuery queryWithClassName:@"Prayers"];

    // If no objects are loaded in memory, we look to the cache first to fill the table
    // and then subsequently do a query against the network.


    [query orderByDescending:@"createdAt"];


    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {

            NSArray *array = [objects objectAtIndex:0];//Selects the first "object" from all the "objects"
            array = [array valueForKey:@"Request"];//Makes a NSArray from the "pairs" values
            _rowTypesList = [array mutableCopy];//Converts the array to a NSMutableArray

            NSLog(@"%@",  _rowTypesList);
        } else {
            // Log details of the failure
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
    }];    [self setupTable];
}

- (void)setupTable
{

    NSLog(@"%@", _rowTypesList);

    [_theActualTable setRowTypes:_rowTypesList];

    for (NSInteger i = 0;_theActualTable.numberOfRows; i++)
    {

        NSObject *row = [_theActualTable rowControllerAtIndex:i];
            TheTable *importantRow = (TheTable *) row;
            [importantRow.textRowLabel setText:???]; //THIS IS PROBLEM AREA, HOW DO I GET TEXT HERE FROM THE MUTABLEARRAY

    }
}

@end

如何将该行的数组值传入标签？

我不太了解Objective C，但我明白了。您需要从ParseQuery回调中调用setupTable并将结果数组传递给它，或者在回调和每次迭代调用中迭代该数组mytable.label.setText(array[i]["property"])

希望它有意义。
