如何在iOS上作为NSDictionary从磁盘加载plist文件？ [英] How do I load a plist file from disk as a NSDictionary on iOS?

问题描述

我想从磁盘（文档，应用程序缓存，...）加载来自资源包的plist文件。

I want to load the plist file from disk (documents, application cache, ...) not from a resource bundle.

推荐答案

您可以使用 - initWithContentsOfFile：或+dictionaryWithContentsOfFile:

从文件加载plist，如果文件不存在则创建该文件：

Load a plist from a file, and create the file if it did not exist:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                    NSUserDomainMask, YES); 
self.plistFile = [[paths objectAtIndex:0]
                    stringByAppendingPathComponent:@"example.plist"];

self.plist = [[NSMutableDictionary alloc] initWithContentsOfFile:plistFile];
if (!plist) {
    self.plist = [NSMutableDictionary new];
    [plist writeToFile:plistFile atomically:YES];
}
