1.苹果系统中大量使用了plist文件来保存配置信息，plist文件由以下对象组成
- NSArray
- NSDictionary
- NSString
- NSData
- NSDate
- NSNumber
2.通过NSArray和NSDictionary的内建方法可以读写plist文件，代码如下
#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
@autoreleasepool {
//写入plist
NSMutableArray *writeData=[[NSMutableArray alloc] init];
NSMutableDictionary *dic=[NSMutableDictionary dictionary];
[dic setObject:@"value123" forKey:@"key1"];
[dic setObject:[NSNumber numberWithInt:200] forKey:@"key2"];
[writeData addObject:dic];
[writeData writeToFile:@"/tmp/test.plist" atomically:YES];
//读取plist
NSArray *readData=[NSArray arrayWithContentsOfFile:@"/tmp/test.plist"];
for (NSDictionary *d in readData){
NSLog(@"value1=%@,value2=%@",[d objectForKey:@"key1"],[d objectForKey:@"key2"]);
}
}
return 0;
}
