如何从plist iOS中读取数组 [英] How to read Array from plist iOS

问题描述

我正在尝试读取包含数组的plist

I am trying to read plist which contains array

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>key1</key>
<string>value1</string>
<key>key2</key>
<string>value2</string>
<key>keyarray1</key>
<array>
    <string>keyitem1</string>
    <string>keyitem2</string>
</array>
</dict>
</plist>

当我尝试读取valueForKey：@keyarray1时，我得到空值。
我试图读作字符串和数组螺母没用。

when i try to read valueForKey:@"keyarray1", I get null value. I tried to read as a string and array nut no use.

我的代码

NSDictionary * values=[[NSDictionary alloc] initWithContentsOfFile:@"values.plist"];
NSArray *arrayValues=[[NSArray alloc] initWithArray:[values valueForKey:@"keyarray1"]];

推荐答案

首先检查你的plist看起来像：

First of all Check your plist looks like:

现在写下您访问plist的以下行

Now write following lines where you are accessing your plist

Objective-C：

NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Values" ofType:@"plist"]];
NSArray *array = [dictionary objectForKey:@"keyarray1"];
NSLog(@"dictionary = %@ \narray = %@", dictionary, array);

以下是我工作窗口的完整截屏（带日志输出）：

Here is the complete screen shot (with log output) of my work window:

Swift：

let dictionary = NSDictionary(contentsOfFile: Bundle.main.pathForResource("Values", ofType: "plist")!);
let array = dictionary?["arrayKey"] as! NSArray
print("dictionary=",  dictionary, "\narray =",  array)
