Question

我成功地将我的plist数组和字典加载到我的表中。我想在练习的详细视图中将exerciseName值设置为UILabel。

<array>
<dict>
    <key>exercises</key>
    <array>
        <dict>
            <key>exerciseDetail</key>
            <string></string>
            <key>exerciseName</key>
            <string>Ab Crunch Machine</string>
        </dict>
        <dict>
            <key>exerciseDetail</key>
            <string></string>
            <key>exerciseName</key>
            <string>Ab Roller</string>
        </dict>
    </array>
    <key>muscleName</key>
    <string>Abdominals</string>
</dict>

练习细节现在是空白的，但最终会在相同练习的详细视图中加载UILabel或UITextView。

我猜我需要做一些像

这样的事情

label.text =[[self.exerciseArray objectAtIndex:indexPath.row]objectForKey:@"exercises"];

编辑：

对于我的exerciseViewController didSelectIndexAtRow我有：

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
    [def setObject:exerciseArray forKey:@"exercises"];
    [def setValue:[NSString stringWithFormat:@"%d",indexPath.row] forKey:@"exercises"];

对于detailViewController的ViewDidLoad，我有： viewDidLoad for exerciseDetailView

 self.navigationItem.title = @"Exercise Detail"; 

NSMutableArray *exerciseDetailArray = [[[NSUserDefaults alloc] objectForKey:@"exercises"] mutableCopy];

int indexValue = [[[NSUserDefaults alloc] valueForKey:@"exercises"] intValue];

name.text =[[exerciseDetailArray objectAtIndex:indexValue] objectForKey:@"exerciseName"];

控制台输出：

2011-03-19 22:52:08.279 Curl[32300:207] exercisedetalarray: (
    {
    exerciseDetail = "";
    exerciseName = "Ab Crunch Machine";
},
    {
    exerciseDetail = "";
    exerciseName = "Ab Roller";
},
    {
    exerciseDetail = "";
    exerciseName = "Advanced Kettlebell Windmill";
},
    {
    exerciseName = "Air Bike";
},
    {
    exerciseName = "Alternate Heel Touchers";
},
    {
    exerciseName = "Barbell Ab Rollout";
},
    {
    exerciseName = "Barbell Side Bend";
},
    {
    exerciseName = "Bent Press";
},
    {
    exerciseName = "Bent-Knee Hip Raise";
},
    {
    exerciseName = "Butt-Ups";
},
    {
    exerciseName = "Cable Crunch";
}

）

2011-03-19 22:52:08.280 Curl[32300:207] index value: 0

使用MaserView NSDefault代码进行编辑：

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
[def setObject:exerciseArray forKey:@"InfoArray"];
[def setValue:[NSString stringWithFormat:@"%d",indexPath.row] forKey:@"indexVal"];

使用detailView NSUserDefaults代码进行编辑：

-(void)viewWillAppear:(BOOL)animated
{    
    NSMutableArray *exerciseDetailArray = [[[NSUserDefaults alloc] objectForKey:@"InfoArray"] mutableCopy];

    int indexValue = [[[NSUserDefaults alloc] valueForKey:@"indexVal"] intValue];

    name.text =[[exerciseDetailArray objectAtIndex:indexValue] objectForKey:@"exerciseName"];
}

@Faisal：

查看您的代码我假设您的标签位于tableView下，因为您使用indexPath.row来索引数组

你的想法看起来很正确。

<强> STEP-1：

将plist中的数据检索到您的数组中（ Plist - ＆gt;数组）

如果您的plist名称为Exercise.plist，请告诉我们，您可以使用以下代码将数据检索到plist

NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"Exercise" ofType:@"plist"];
exerciseArray = [NSArray arrayWithContentsOfFile:plistPath];

第2步：

从数组中获取数据到标签的文本（数组 - ＆gt;标签文本）

然后使用下面的代码

从数组值设置UILabel的文本

label.text =[[exerciseArray objectAtIndex:indexPath.row]objectForKey:@"exercises"];

注意：

要在masterView和detailView之间使用相同的数组，可以在masterView中的didSelectRowAtIndexPath上的NSUserDefaults中设置数组，并在detailView中检索相同的数组。

您可以使用以下代码执行此操作：

在didSelectRowAtIndexPath方法的masterView中：

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
[def setObject:exerciseArray forKey:@"InfoArray"];
[def setValue:[NSString stringWithFormat:@"%d",indexPath.row] forKey:@"indexVal"];

您可以使用以下代码在detailView中检索该数组：

NSMutableArray *exerciseDetailArray = [[[NSUserDefaults standardUserDefaults] objectForKey:@"InfoArray"] mutableCopy];

int indexValue = [[[NSUserDefaults standardUserDefaults] valueForKey:@"indexVal"] intValue];

label.text =[[exerciseDetailArray objectAtIndex:indexValue] objectForKey:@"exercises"];

OR

NSArray *exerciseDetailArray = [[NSArray alloc] initWithContentsOfArray:[[NSUserDefaults alloc] objectForKey:@"InfoArray"]];

int indexValue = [[[NSUserDefaults standardUserDefaults] valueForKey:@"indexVal"] intValue];

label.text =[[exerciseDetailArray objectAtIndex:indexValue] objectForKey:@"exercises"];

希望这可以帮助你：）

最终编辑：

将didSelectRowAtIndexPath:方法替换为SpecificExerciseTableViewController.m

中的以下方法

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.

     DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
     detailViewController.exerciseArray = [[self.exerciseArray objectAtIndex:indexPath.row]objectForKey:@"exercises"];
     // Pass the selected object to the new view controller.


    NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
    [def setObject:exerciseArray forKey:@"InfoArray"];
    [def setValue:[NSString stringWithFormat:@"%d",indexPath.row] forKey:@"indexVal"];
    NSLog(@"Index inexpath:%d",indexPath.row);
    int indexValue = [[[NSUserDefaults standardUserDefaults] valueForKey:@"indexVal"] intValue];
    NSLog(@"index value master view: %d",indexValue);

    [self.navigationController pushViewController:detailViewController animated:YES];
    [detailViewController release];

}

这肯定会奏效：）

从Plist设置UILabel文本？
