iphone - 创建一个 plist 文件

Question

我想将数组写入 plist，当我在文档文件夹中手动创建 plist 时效果很好。

但是当我检查 plist 是否存在并且如果不从主包中的 plist 创建它时，什么也不会发生......

我按照 Property List Programming Guide 那样做了这个已经写完了。

NSString *plistRootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *plistPath = [plistRootPath stringByAppendingPathComponent:@"list.plist"];

if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) {

    plistPath = [[NSBundle mainBundle] pathForResource:@"list" ofType:@"plist"];

}

我错过了什么？

编辑:

我在一个单独的应用程序中尝试了该功能，并且它有效。 所以我又试了一次:

 NString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
 NSString *plistPath = [rootPath stringByAppendingPathComponent:@"list.plist"]; 

self.ListArray = [NSMutableArray arrayWithContentsOfFile:plistPath]; 
NSLog(@"preSave: %@", [ListArray count]);
NSLog(@"%@", plistPath);

日志显示:

但是目录中没有文件!

NSString *DocPath=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

filePath=[DocPath stringByAppendingPathComponent:@"AlarmClock.plist"];

if (![[NSFileManager defaultManager] fileExistsAtPath:filePath]) 
{
    NSString *path=[[NSBundle mainBundle] pathForResource:@"AlarmClock" ofType:@"plist"];
    NSLog(@"file path: %@",filePath);
    NSDictionary *info=[NSDictionary dictionaryWithContentsOfFile:path];
    [info writeToFile:filePath atomically:YES];
}

//***试试这个...
