ios - UITableView重复重复单元格

Question

所以我有这个UITableView，并且它一遍又一遍地重复单元格，我不知道为什么，我已经尝试过谷歌搜索并查看其他类似的堆栈溢出问题，但是它们中的任何解决方案似乎都无法解决我遇到的问题。

我的代码如下:

NSArray在ViewDidLoad方法中:

tableViewContents = @[

表格检视方法

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

//Amount of sections
return 1;

}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

//Amount of rows in each section
return [tableViewContents count];

}

NSString *contentsString = tableViewContents[indexPath.row];
NSArray *contentsArray = [contentsString componentsSeparatedByString:@":"];

//Cell Identifier

    eventNameLabel = [[UILabel alloc]init];
    eventDateLabel = [[UILabel alloc]init];
    eventLocationLabel = [[UILabel alloc]init];


    eventNameLabel.frame = CGRectMake(10, 10, 300, 20);
    eventNameLabel.font = [UIFont boldSystemFontOfSize:14];
    eventNameLabel.textColor = [UIColor colorWithRed:231.0f/255.0f

                                               alpha:1.0f];


    eventDateLabel.frame = CGRectMake(10, 40, 300, 20);
    eventDateLabel.font = [UIFont systemFontOfSize:12];
    eventDateLabel.textColor = [UIColor grayColor];

    eventLocationLabel.frame = CGRectMake(10, 70, 300, 20);
    eventLocationLabel.font = [UIFont systemFontOfSize:12];
    eventLocationLabel.textColor = [UIColor grayColor];

    [cell addSubview:eventNameLabel];
    [cell addSubview:eventDateLabel];
    [cell addSubview:eventLocationLabel];

}

eventNameLabel.text = contentsArray[0];
eventDateLabel.text = contentsArray[1];
eventLocationLabel.text = contentsArray[2];


//Return Cell
return cell;

}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 100;
}

预先感谢您的帮助。

对于您的要求的明显答案是自定义单元格。不必按照cellforrowaatIndexpath方法进行所有编码，而是根据需要自定义单元格并将其用于表。处理自定义单元会容易得多。请参阅这些链接，以了解如何自定义tableViewCell。 http://www.appcoda.com/customize-table-view-cells-for-uitableview/或http://www.appcoda.com/ios-programming-customize-uitableview-storyboard/用于自定义单元格。
