ios - 如何从 plist iOS 读取数组

Question

我正在尝试读取包含数组的 plist

<?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，我得到了空值。 我尝试读取字符串和数组坚果没有用。

我的代码

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

首先检查你的 plist 看起来像:

现在在你访问 plist 的地方写下下面几行

objective-C :

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

这是我工作窗口的完整屏幕截图(带有日志输出):

swift :

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