如何将数据写入plist

Question

HI 你可以给我发送示例代码，将数据添加到.plist中。 .my plist的格式如下。请帮助我

<?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>
<string>http://localhost:8888/sample</string>
<string>http://localhost:8888/sample</string>
</array>
</plist>

我将从实现代码中发送url字符串。请在此帮助我...

-(IBAction)AddFieldid)sender;
{
NSMutableArray *myPrimaryinfo = [[NSMutableArray arrayWithCapacity:6]retain];

NSArray *keys = [NSArray arrayWithObjects:@"string",nil];

[myPrimaryinfo addObject:[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:
[NSString stringWithFormat:@"sample"],nil]forKeys:keys]];


NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDire ctory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"urls.plist"];
[myPrimaryinfo writeToFile:path atomically:NO];
NSLog(@"PrimaryInfo array: %@", myPrimaryinfo);
}

我想这样的东西会起作用（不太适合iphone的东西）：

// Loading
NSString *path = ...
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:path];

// Manipulating
NSObject *newElement = ...
[array addObject:newElement];

// Storing
[array writeToFile:path atomically:YES];
