在UITableViewController中遇到UISearchBar问题 [英] Having Problems With UISearchBar in UITableViewController

问题描述

我正在尝试将UISearchBar添加到我的UITableView。

I am trying to add a UISearchBar to my UITableView.

这是他们用来搜索的方法：

This is the method they use to search:

- (void) searchTableView {

NSString *searchText = searchBar.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];

for (NSDictionary *dictionary in listOfItems)
{
NSArray *array = [dictionary objectForKey:@"Countries"];
[searchArray addObjectsFromArray:array];
}

for (NSString *sTemp in searchArray)
{
NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];

if (titleResultsRange.length > 0)
[copyListOfItems addObject:sTemp];
}

[searchArray release];
searchArray = nil;
}

但我没有字典，我只想搜索我的字典数组'exerciseArray'是这样的初始化：

But I don't have a dictionary, I just want to search in my array 'exerciseArray' which is init like this:

NSString *path = [[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"];
NSMutableArray *rootLevel = [[NSMutableArray alloc]initWithContentsOfFile:path];
self.exerciseArray = rootLevel;
[rootLevel release];

当我NSLog它时，我得到：

When I NSLog it, I get:

exerciseArray: (
        {
        exerciseName = "Balance Board";
    },
        {
        exerciseName = "Barbell Seated Calf Raise";
    },
        {
        exerciseName = "Calf Press On The Leg Press Machine";
    },
        {
        exerciseName = "Calf Raises- With Bands";
    },

所以任何人都可以帮我修改搜索方法为了适应我拥有的数组？它似乎有一个关键。

So can anyone help me modify the search method to fit the array I have? It seems to have a key in it.

我试过这个但它没有工作并且崩溃了 NSRange titleResultsRange = [sTemp rangeOfString：searchText options：NSCaseInsensitiveSearch];

I tried this but it did not work and crashed at line NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];

错误 ***由于未被捕获而终止应用异常'NSInvalidArgumentException'，原因：' - [__ NSCFDictionary rangeOfString：options：]：无法识别的选择器发送到实例0x2d6450

- (void) searchTableView {

    NSString *searchText = searchBar.text;
    NSLog(@"exerciseArray: %@", exerciseArray);
    for (NSString *sTemp in listOfItems)
    {
        if (sTemp) {
            NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];

            if (titleResultsRange.length > 0)
                [copyListOfItems addObject:sTemp];
        }
    }
}

推荐答案

我相信NSPredicates是在数组中搜索的好方法。你可以参考这个链接.. 使用NSPredicate根据NSDictionary密钥过滤NSArray

I believe NSPredicates are good way to search in arrays.. You can refer to this link.. Using NSPredicate to filter an NSArray based on NSDictionary keys
