IOS对plist配置文件的读写操作

读取：

//首先读取studentInfo.plist中的数据
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"customInfo" ofType:@"plist"];
NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
    
//将学生信息填入视图
NSDictionary *tmpInfo = [dictionary objectForKey: @"Student"];
self.stuName.text = [NSString stringWithFormat:@"%@", [tmpInfo objectForKey: @"Name"]];
self.stuSex.text = [NSString stringWithFormat:@"%@", [tmpInfo objectForKey: @"Sex"]];
self.stuNum.text = [NSString stringWithFormat:@"%@", [tmpInfo objectForKey: @"Num"]];
    
//将导师信息写入视图
tmpInfo = [dictionary objectForKey: @"Mentor"];
self.mtName.text = [NSString stringWithFormat:@"%@", [tmpInfo objectForKey: @"Name"]];
self.mtSex.text = [NSString stringWithFormat:@"%@", [tmpInfo objectForKey: @"Sex"]];

全新写入：

NSMutableDictionary *dictplist = [[NSMutableDictionary alloc ] init];
//定义第一个插件的属性
NSMutableDictionary *plugin1 = [[NSMutableDictionary alloc]init];
[plugin1 setObject:@"张三" forKey:@"name1"];
[plugin1 setObject:@"李四" forKey:@"name2"];
//定义第二个插件的属性
NSMutableDictionary *plugin2 = [[NSMutableDictionary alloc]init];
[plugin2 setObject:@"王五" forKey:@"name1"];
[plugin2 setObject:@"赵斌" forKey:@"name2"];
//设置属性值
[dictplist setObject:plugin1 forKey:@"初一班"];
[dictplist setObject:plugin2 forKey:@"初二班"];
//写入文件
[dictplist writeToFile:plistPath atomically:YES];

//修改某一配置项。

//载入配置文件。   
    NSString* plistPath = [NSString stringWithFormat:@"%@/letters.plist",[[Globals getResourceManager] getResPath]];
        
    NSMutableDictionary* dicWrite = [[[NSMutableDictionary alloc] initWithContentsOfFile:plistPath] mutableCopy];
    NSMutableDictionary* dicWLetter = [dicWrite objectForKey:letter];
    NSString* v = alertView.tag == 1 ? @"1" : @"0";
    [dicWLetter setValue:v forKey:@"isOk"];
    [dicWrite setValue:dicWLetter forKey:letter];
    
    [dicWrite writeToFile:plistPath atomically:YES];
    [dicWrite release];
    dicWrite = nil;
