如何在iOS上作为NSDictionary从磁盘加载plist文件？

Question

我想从磁盘（文档，应用程序缓存，...）加载plist文件，而不是从资源包中加载。

Answer 1

您可以使用-initWithContentsOfFile:或+dictionaryWithContentsOfFile:

从任何可访问的文件路径加载plist

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];
}

Answer 2

一点清洁：

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"plistName" ofType:@"plist"]; 
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
