[英]sectioned UITableView sourced from a pList
I'm having trouble finding a easy to understand tutorial on having a sectioned UITableView which gets its data from a pList file. 我很难找到一个易于理解的教程,该教程有一个分段的UITableView,它从pList文件获取数据。
Things im having trouble with, is how to properly structure the pList file to cater for 2 different sections. 我遇到的麻烦是如何正确构造pList文件以适应2个不同的部分。
The root of the plist should be an array. plist的根应该是一个数组。 The array should contain two dictionaries (your sections).
该数组应包含两个字典(您的部分)。 The dictionaries will contain two keys: one for section title and one for the rows in the section.
词典将包含两个键:一个用于节标题,一个用于节中的行。
Assuming you read your plist into an NSArray* sections, you can return the section, row count, section title and cell titles using the code below. 假设您将plist读入NSArray *部分,则可以使用以下代码返回部分,行数,部分标题和单元格标题。
Your plist file would look like this: 您的plist文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<dict>
<key>Title</key>
<string>Section1</string>
<key>Rows</key>
<array>
<string>Section1 Item1</string>
<string>Section1 Item2</string>
</array>
</dict>
<dict>
<key>Title</key>
<string>Section2</string>
<key>Rows</key>
<array>
<string>Section2 Item1</string>
<string>Section2 Item2</string>
</array>
</dict>
</array>
</plist>
#import "RootViewController.h"
@interface RootViewController ()
@property (copy, nonatomic) NSArray* tableData;
@end
@implementation RootViewController
@synthesize tableData;
- (void) dealloc
{
self.tableData = nil;
[super dealloc];
}
- (void) viewDidLoad
{
[super viewDidLoad];
self.tableData = [NSArray arrayWithContentsOfFile: [[NSBundle mainBundle] pathForResource: @"Table" ofType: @"plist"]];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView;
{
return [tableData count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
return [[[tableData objectAtIndex: section] objectForKey: @"Rows"] count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;
{
return [[tableData objectAtIndex: section] objectForKey: @"Title"];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [[[tableData objectAtIndex: indexPath.section] objectForKey: @"Rows"] objectAtIndex: indexPath.row];
return cell;
}
