Question

我已经向Xcode添加了一个文本文件，现在我想用它创建一个字符串。如何加载它并将其放入字符串？

NewsStory1.txt是文件，我正在使用Obj-C。

Answer 1

NSString *path = [[NSBundle mainBundle] pathForResource:@"NewsStory1" ofType:@"txt"];
NSString *content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

请参阅Apple的NSString的iOS API文档，特别是“从文件创建和初始化字符串”部分

Answer 2

在swift中

let path = NSBundle.mainBundle().pathForResource("home", ofType: "html")

    do {
        let content = try String(contentsOfFile:path!, encoding: NSUTF8StringEncoding)} catch _ as NSError {}

Answer 3

非常简单

只需创建如下方法

- (void)customStringFromFile
{
    NSString* filePath = [[NSBundle mainBundle] pathForResource:@"NewsStory1" ofType:@"txt"];
    NSString *stringContent = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
    NSLog(@"\n Result = %@",stringContent);
}

Answer 4

在Swift 4中，可以这样操作：

let path = Bundle.main.path(forResource: "test_data", ofType: "txt")
if let path = path {
    do {
        let content = try String(contentsOfFile: path, encoding: String.Encoding.utf8)
        print(content)
    } catch let error as NSError {
        print("Error occured: \(error.localizedDescription)")
    }
} else {
    print("Path not available")
}
