objective-c - 创建一个包含多个字符串的 plist

Question

我有多个字符串，我想使用目标 c 写入一个 plist。谁能告诉我具体怎么做？我很感激

Answer 1

正如 H2CO3 所暗示的，您可以使用NSArray'writeToFile:atomically:方法。

例如：

NSArray *arr = @[
    @"my first string",
    @"my second string",
    @"and the last one"
];
[arr writeToFile:@"./out.plist" atomically:NO]; // Or YES depending on your needs

Answer 2

这是一种可能性：

// Create the path that you want to write your plist to.
NSError *error = nil;
NSURL *documentsURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:YES error:&error];
if (documentsURL == nil) {
    NSLog(@"Error finding user documents in directory: %@", [error localizedDescription]);
    return nil;
}
NSString *path = [[documentsURL path] stringByAppendingPathComponent:@"YourFile.plist"];

// Populate your strings and save to the plist specified in the above path.
NSString *kRoot = @"kRoot"; 
NSMutableDictionary *tempDict = [NSMutableDictionary dictionary];
tempDict[kRoot] = [NSMutableArray array];
[tempDict[kRoot] addObject:@"String 1"];
[tempDict[kRoot] addObject:@"String 2"];
[tempDict[kRoot] addObject:@"String 3"];
// Etc, add all your strings
if (![tempDict writeToFile:path atomically:YES])
{
    NSLog(@"Error writing data to path %@", path);
}
