我在我的程序中包含了一个 plist 文件并在本地调用它
NSString *plistpath = [[NSBundle mainBundle] pathForResource:@"pli" ofType:@"plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:plistpath];
NSArray *cont = [dict allValues];
我希望我的程序在我手动（而不是通过程序）更新文件时读取文件，在运行时从 plist 文件中添加或删除数据，而不必停止执行并再次开始运行它。有什么办法可以实现这一目标吗？
请帮忙
这是将数据保存在 .plist 文件中的方法
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
// get documents path
NSString *documentsPath = [paths objectAtIndex:0];
// get the path to our Data/plist file
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"myData.plist"];
NSError *writeError = nil;
NSData *plistData = [NSPropertyListSerialization dataWithPropertyList:yourDictionary format:NSPropertyListXMLFormat_v1_0 options:NSPropertyListImmutable error:&writeError];
if(plistData)
{
[plistData writeToFile:plistPath atomically:YES];
NSLog(@"Data saved sucessfully");
}
else
{
NSLog(@"Error in saveData: %@", writeError.localizedDescription);
}
从包中读取 plist 并从中获取根字典
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"myData.plist"];
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath])
{
plistPath = [[NSBundle mainBundle] pathForResource:@"myData" ofType:@"plist"];
}
NSDictionary *resultDic = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
