读取文本文件并将其转换为字符串

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];

有关NSString的信息,请参阅Apple的iOS API文档,特别是"从文件创建和初始化字符串"一节

Answer 2

在迅速

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

只需创建一个方法如下

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