Question

我正在努力实现一个搜索栏，用于搜索表格视图，我有很多错误。

Phrasebook.h

#import <Foundation/Foundation.h>

@interface Phrasebook : NSObject

@property (nonatomic, strong) NSString *name; //name of phrase
@property (nonatomic, strong) NSString *translation; //translation of name

@end

Phrasebook.m

#import "Phrasebook.h"

@implementation Phrasebook

@end

PhrasebookTableCell.h

#import <UIKit/UIKit.h>

@interface PhrasebookTableCell : UITableViewCell

@property (nonatomic, weak) IBOutlet UILabel *nameLabel;
@property (nonatomic, weak) IBOutlet UILabel *translationLabel;

@end

PhrasebookTableCell.m

#import "PhrasebookTableCell.h"

@implementation PhrasebookTableCell

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

@end

有问题的.m文件的代码：

{
    static NSString *CellIdentifier = @"CustomTableCell";
    ERROR PhrasebookTableCell *cell = (PhrasebookTableCell *)[[self.tableView         dequeueReusableCellWithIdentifier:CellIdentifier]]; ERROR

    // Configure the cell...
    ERROR if (cell == nil) {
        cell = [[PhrasebookTableCell alloc] initWithStyle:UITableViewCellStyleDefault  

reuseIdentifier:CellIdentifier]; ERROR
    }

    // Display recipe in the table cell
    ERROR Phrasebook *phrasebook = [Phrasebook objectAtIndex:indexPath.row];
    cell.nameLabel.text = phrasebook.name;
    cell.translationLabel.text = phrasebook.translation;

    return cell; ERROR
}

错误：
1）解析问题：预期标识符
2）ARC语义问题：没有可见的@interface用于＆＃39; PhrasebookTableCell＆＃39;声明选择器＆＃39; initWithStyle：reuseIdentifier：＆＃39;
3）ARC语义问题：选择器没有已知的类方法＆＃39; objectAtIndex：＆＃39;
4）语义问题：Property＆＃39; nameLabel＆＃39;没有找到类型对象＆＃39; PhrasebookTableCell *＆＃39;
5）语义问题：属性＆＃39; translationLabel＆＃39;没有找到类型为＆＃39; PhrasebookTableCell *＆＃39;

的对象

Answer 1

在相关的.m文件的第3行中，当单个[[就足够时，您会有两个[括号。删除一个[]对，然后重试。

像这样：

PhrasebookTableCell *cell = (PhrasebookTableCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];

Xcode 5多个错误，＃import不导入头文件
