期待答案。谢谢。如果我猜对了,你想知道如何在应用程序外部和iOS设置中显示设置,那么请退出。这应该让你开始 从下面的链接中删除: 我一直在四处搜索,但找不到样板解决方案,所以我创建了自己的代码来实现这一点。它支持设置类型标题、组、文本字段、多值和切换开关 它不支持滑动条 此解决方案支持纵向和横向模式,还可以处理设备方向的变化 首先,我假设您使用以下代码从Settings.bundle读取默认值
- (void) registerDefaultsFromSettingsBundle
{
NSLog(@"Registering default values from Settings.bundle");
NSUserDefaults * defs = [NSUserDefaults standardUserDefaults];
[defs synchronize];
NSString *settingsBundle = [[NSBundle mainBundle] pathForResource: @"Settings" ofType: @"bundle"];
if(!settingsBundle)
{
NSLog(@"Could not find Settings.bundle");
return;
}
NSDictionary *settings = [NSDictionary dictionaryWithContentsOfFile:[settingsBundle stringByAppendingPathComponent: @"Root.plist"]];
NSArray *preferences = [settings objectForKey: @"PreferenceSpecifiers"];
NSMutableDictionary *defaultsToRegister = [[NSMutableDictionary alloc] initWithCapacity:[preferences count]];
for (NSDictionary *prefSpecification in preferences)
{
NSString *key = [prefSpecification objectForKey:@"Key"];
if (key)
{
// check if value readable in userDefaults
id currentObject = [defs objectForKey: key];
if (currentObject == nil)
{
// not readable: set value from Settings.bundle
id objectToSet = [prefSpecification objectForKey: @"DefaultValue"];
[defaultsToRegister setObject: objectToSet forKey: key];
NSLog(@"Setting object %@ for key %@", objectToSet, key);
}
else
{
// already readable: don't touch
NSLog(@"Key %@ is readable (value: %@), nothing written to defaults.", key, currentObject);
}
}
}
[defs registerDefaults: defaultsToRegister];
[defs synchronize];
}
好了,现在你需要上两节课。设置StableViewController和多值TableViewController
设置StableViewController.h
情节提要现在转到情节提要并创建TableViewController。选择TableViewController并选择“编辑器”->“嵌入”->“导航控制器”
将TableViewController的类设置为SettingsTableViewController。将单元格的标识符设置为“单元格”,将第二个TableViewCell添加到TableView,并将其标识符设置为“多值单元格”。添加第二个TableViewController,按住CTRL键并单击,然后从多值单元格拖动到第二个TableViewController。将第二个TableViewController的类设置为多值TableViewController。将第二个TableViewController中的单元格标识符也设置为“单元格”。就这样 您可以通过多值元素来实现这一点。当用户点击包含多值元素的首选项时,设置应用程序将显示一个新页面,其中包含可供选择的值。如果需要,用谷歌搜索教程(设置包的多值选项)
#import "SettingViewController.h"
NSInteger selectedIndex;
//Use this, it works for me
- (void)viewDidLoad
{
selectedIndex = 0;
[super viewDidLoad];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 50.0f;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_arrayForSaveSetting count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = nil;
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
if (indexPath.row==selectedIndex) {
cell.accessoryType =UITableViewCellAccessoryCheckmark;
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
selectedIndex=indexPath.row;
[_tblSaveSetting reloadData];
}
以下是详细信息:感谢您的快速回复。我已经知道如何在应用程序外设置。但我想问的是,在你的iOS应用程序设置包中是否可以有一个表视图。如果可能的话,我该怎么做?为什么要写这些代码?OP询问如何将选择表设置为外部设置包的一部分。不需要代码。查看设置包的“多值”选项。
