How do I load a plist file from disk as a NSDictionary on iOS?
提问by sorin
I want to load the plist file from disk (documents, application cache, ...) not from a resource bundle.
我想从磁盘（文档、应用程序缓存等）而不是从资源包加载 plist 文件。

You can load a plist from any accessible file path with -initWithContentsOfFile:or +dictionaryWithContentsOfFile:
您可以使用-initWithContentsOfFile:或+dictionaryWithContentsOfFile从任何可访问的文件路径加载 plist ：
Load a plist from a file, and create the file if it did not exist:
从文件加载 plist，如果文件不存在则创建该文件：
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];
}

A little cleaner:
清洁一点：
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"plistName" ofType:@"plist"];
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
