如何在UITable的不同部分中存储多行的多个文本字段值

Question

我目前有两个字典数组来存储数据：

var workoutData = [String:[String:[String:Int]]]()

和

var workoutSets = [String:[String:Int]]()

当在该行的末尾选中复选框时，我将数据分配给workoutSets，然后将workoutSets数据整体分配给workoutData：

workoutSets["Set \(indexPath.row)"] = ["Weight":Int(weightLifted)!, "Reps":Int(repsPerformed)!]

workoutData[exercise] = workoutSets

这适用于第一部分数据，但是当我将数据输入UITable中下一部分的第一行并检查复选框时，其他数据行的值会被转发。我添加了一个屏幕截图，以便您可以看到我面临的情况。

打印时，workoutData看起来像

["Cable Row": ["Set 2": ["Weight": 10, "Reps": 12],"Set 3": ["Weight": 28, "Reps": 8],"Set 1": ["Weight": 45, "Reps": 5]], 
"Arnold Press": ["Set 2": ["Weight": 10, "Reps": 12], "Set 3": ["Weight": 28, "Reps": 8], "Set 1": ["Weight": 10, "Reps": 12]]]

是否有更好的方法来存储此数据，因为我在加载表时也使用workoutData方法中的cellForRowAt，以便在加载新单元格时不会重复使用单元格数据

对于存储具有已定义属性和属性的结构化对象的数据，将其定义为从NSObject继承的对象更有意义。

对于此自定义对象，您可以将所需的属性定义为＆＃34; weight＆＃34; ＆安培; ＆＃34;代表＆＃34 ;.还要创建类Set的复合对象，您可以在其中添加对象数组。鉴于下面的对象层次结构可能会有所帮助。

public class Workout { var displayName:String? var sets:[Set]? var key:String? }

public class Set { var weight:Int? var reps:Int? }

var workouts = [Workout]()

var workout1 = Workout() workout1.displayName = "Arnold Press" workout1.sets = [Set]() var set1 = Set() set1.reps = 10 set1.weight = 80 workout1.sets?.append(set1)

var set2 = Set() set2.reps = 12 set2.weight = 80 workout1.sets?.append(set2)

var workout2 = Workout() workout2.displayName = "Cable Row" workout2.sets = [Set]() var set11 = Set() set11.reps = 10 set11.weight = 80 workout1.sets?.append(set11)

var set22 = Set() set22.reps = 12 set22.weight = 80 workout2.sets?.append(set22)

workouts.append(workout1) workouts.append(workout2)
