大佬教程收集整理的这篇文章主要介绍了iphone – 崩溃[[NSBundle mainBundle] loadNibnamed：owner：options：]，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我不能想出这一个.我在IB中创建了一个定制的UITableViewCell.据我所知,我将所有的UILabels的所有对象正确连接在一起,并且所有的对象都建立在没有任何错误的情况下.当我尝试使用自定义单元格时,当我尝试加载NIB时,该应用停止.我列出了我在下面的地方.

任何帮助或提示或在哪里寻找这一个,将不胜感激.

谢谢,

这是我的UITableViewCell接口和实现方法.我不知道我真的需要分配init标签.我试过两种方式…

//  ArrivalTimesCell.h

#import <UIKit/UIKit.h>

@interface ArrivalTimesCell : UITableViewCell {
    IBOutlet UILabel *cityArrivalTimeLabel;
    IBOutlet UILabel *optimumArrivalTimeLabel;
    IBOutlet UILabel *arrivalAvoidTimesLabel;
    IBOutlet UILabel *arrivalTimeNotSetLabel;

}
@property (nonatomic,retain)IBOutlet UILabel *cityArrivalTimeLabel;
@property (nonatomic,retain)IBOutlet UILabel *optimumArrivalTimeLabel;
@property (nonatomic,retain)IBOutlet UILabel *arrivalAvoidTimesLabel;
@property (nonatomic,retain)IBOutlet UILabel *arrivalTimeNotSetLabel;

@end

//  ArrivalTimesCell.m

#import "ArrivalTimesCell.h"

@implementation ArrivalTimesCell
@synthesize arrivalTimeNotSetLabel,arrivalAvoidTimesLabel,optimumArrivalTimeLabel,cityArrivalTimeLabel;

- (id)initWithStyle:(UITableViewCellStylE)style reusEIDentifier:(NSString *)reusEIDentifier{
    self = [super initWithStyle:style reusEIDentifier:reusEIDentifier];
    if (self) {
        arrivalTimeNotSetLabel = [[UILabel alloc] init];
        arrivalAvoidTimesLabel = [[UILabel alloc] init];
        optimumArrivalTimeLabel = [[UILabel alloc] init];
        cityArrivalTimeLabel = [[UILabel alloc] init];
    }
    return self;
}

- (void)setSELEcted:(BOOL)SELEcted animated:(BOOL)animated{
    [super setSELEcted:SELEcted animated:animated];

}

- (void)dealloc{
    [super dealloc];
    [arrivalTimeNotSetLabel release];
    arrivalTimeNotSetLabel = nil;
    [arrivalAvoidTimesLabel release];
    arrivalAvoidTimesLabel = nil;
    [optimumArrivalTimeLabel release];
    optimumArrivalTimeLabel = nil;
    [cityArrivalTimeLabel release];
    cityArrivalTimeLabel = nil;
}

@end

这是UITableView的cellForRowATindexPath的一部分

//  TripEditViewController.m

#import "ArrivalTimesCell.h"

@implementation TripEditViewController

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowATindexPath:(NSIndexPath *)indexPath {

    CellIdentifier = @"ArrivalTimesCell";
    ArrivalTimesCell *cell = (ArrivalTimesCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if(cell == nil){
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"ArrivalTimesCell" owner:nil options:nil];

        for (id currentObject in topLevelObjects) {
            if ([currentObject isKindOfClass:[UITableViewCell class]]) {
                cell = (ArrivalTimesCell *) currentObject;
                break;
             }
         }      
    }


    cell.cityArrivalTimeLabel.text = @"whatever"
    cell.arrivalAvoidTimesLabel.text = @"whatever";
    cell.optimumArrivalTimeLabel.text = @"whatever";
    cell.arrivalTimeNotSetLabel.text = @"whatever";

    return cell;  
}
