AddRecord TableView控制器 - ＆gt; MasterTableView控制器 - ＆gt;第二个（过滤器）TableView控制器 - ＆gt; DetailView控制器

标签： ios uitableview navigationcontroller

我是iOS编程的新手（以及一般的编程）。我正在尝试基于Apple提供的Birdighting示例（http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/SecondiOSAppTutorial/Introduction/Introduction.html）来制作iPhone应用程序。不同之处在于我将在AddWorkout TableView控制器中创建Body Building的训练（而不是Birdightings），将训练传递给Master TableView控制器，然后通过选择训练单元，可以显示第二个TableView控制器，类似于大师的一个，显示按肌肉带排序的锻炼事件;然后，选择肌肉带细胞，推动具有该肌肉带锻炼的所有相关参数的DetailView控制器（锻炼类型，体重，系列号......）。所有这些都嵌入在导航控制器中。

问题是我无法在第二个TableView控制器（MuscleBandViewController）上传递新记录，因此我无法将其推送到detailViewController。有什么建议吗？我已经被困了一个星期了（抱歉我的英语不好：我是意大利语）。 这是我的DataController.h代码： 

#import <Foundation/Foundation.h>
@class Workouts;

@interface IFitDataController : NSObject

@property (nonatomic, copy)NSMutableArray *masterWorkoutsList;
@property (nonatomic, copy)NSMutableArray *masterMuscleBandList;

- (NSUInteger)countOfList;
- (NSUInteger)countOfMuscleBandList;
- (Workouts *)objectInListAtIndex:(NSUInteger)theIndex;
- (Workouts *)objectInMasterMuscleBandListAtIndex:(NSUInteger)index;
- (void)addWorkoutsWithWorkouts:(Workouts *)thisWorkout;
@end

此处DataController.m： 

#import "IFitDataController.h"
#import "Workouts.h"

@interface IFitDataController ()
- (void)initializeDefaultDataList;

@end

@interface IFitDataController ()
- (void)initializeMuscleBandDataList;

@end
@implementation IFitDataController

- (void)initializeDefaultDataList {

    NSMutableArray *workoutsList = [[NSMutableArray alloc] init];
    self.masterWorkoutsList = workoutsList;
    Workouts *thisWorkout;
    NSDate *today = [NSDate date];
    thisWorkout = [[Workouts alloc] initWithName:@"Pectorals" exercise:@"Pectoral Machine" series:@"3" nActionsInSerie:@"10" measure:@"Kg"  weight:@"25" date:today comment:@"Add your comment"];
    [self addWorkoutsWithWorkouts:thisWorkout];
}

- (void)setMasterWorkoutsList:(NSMutableArray *)newList {

    if (_masterWorkoutsList != newList) {
        _masterWorkoutsList = [newList mutableCopy];
    }
}

- (void)initializeMuscleBandDataList {

    NSMutableArray *muscleBandList = [[NSMutableArray alloc]init];
    self.masterMuscleBandList = muscleBandList;
    Workouts *thisWorkout;
    NSDate *today = [NSDate date];
    thisWorkout = [[Workouts alloc] initWithName:@"Pectorals" exercise:@"Pectoral Machine" series:@"3" nActionsInSerie:@"10" measure:@"Kg"  weight:@"25" date:today comment:@"Add your comment"];
    [self addWorkoutsWithWorkouts:thisWorkout];
}

- (void)setMasterMuscleBandList:(NSMutableArray *)newMuscleBandList {

    if ((_masterMuscleBandList != newMuscleBandList)) {
        _masterMuscleBandList = [newMuscleBandList mutableCopy];
    }
}


- (id)init {

    if (self = [super init]) {
        [self initializeDefaultDataList];
        [self initializeMuscleBandDataList];
        return self;
    }

    return nil;
}



- (NSUInteger)countOfList {

    return [self.masterWorkoutsList count];

}

- (NSUInteger)countOfMuscleBandList {

    return [self.masterMuscleBandList count];
}

- (Workouts *)objectInListAtIndex:(NSUInteger)theIndex {

    return [self.masterWorkoutsList objectAtIndex:theIndex];
}

- (Workouts *)objectInMasterMuscleBandListAtIndex:(NSUInteger)index {

    return [self.masterMuscleBandList objectAtIndex:index];
}

- (void)addWorkoutsWithWorkouts:(Workouts *)thisWorkout {

    [self.masterWorkoutsList addObject:thisWorkout];
    [self.masterMuscleBandList addObject:thisWorkout];
}
@end

这是我的AddWorkoutViewController.h： 

#import <UIKit/UIKit.h>
