iphone 真机写入plist文件(非模拟器)

其实写入不到真机里面主要是你写入时，当前那文件夹里你要写入的plist根本不存在

所以你怎么写都写不进去，所以你必须先创建你要写入的plist;

你用这样初始化程序就能自己创建：

NSMutableArray *dictplist = [[NSMutableArray alloc] init]; [dictplist insertObject:markName atIndex:0]; [dictplist writeToFile:plistPath atomically:YES];
直接下面这种是不行的

NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:plistPath]; [array insertObject:markName atIndex:0]; [array writeToFile:plistPath atomically:YES];

下面是具体的实现方法

一般plist 的写入位置在

写入文件的位置:(Library文件夹)

NSString *lib = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) lastObject]; NSString *libPath = [lib stringByAppendingString:@"/Caches"]; NSString* plistPath = [libPath stringByAppendingFormat:@"/bookmark.plist"]; NSLog(@"%@",plistPath); if(![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) { NSMutableArray *dictplist = [[NSMutableArray alloc] init]; [dictplist insertObject:markName atIndex:0]; [dictplist writeToFile:plistPath atomically:YES]; NSLog(@"------1-----%@",dictplist); } else { NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:plistPath]; [array insertObject:markName atIndex:0]; [array writeToFile:plistPath atomically:YES]; NSLog(@"-------2----%@",array); } 写入文件的位置:（ Document 文件夹)
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //获取完整路径 NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *plistPath = [documentsDirectory stringByAppendingPathComponent:@"test2.plist"]; NSLog(@"%@",plistPath); if(![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) { NSMutableArray *dictplist = [[NSMutableArray alloc] init]; [dictplist insertObject:markName atIndex:0]; [dictplist writeToFile:plistPath atomically:YES]; NSLog(@"------1-----%@",dictplist); } else { NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:plistPath]; [array insertObject:markName atIndex:0]; [array writeToFile:plistPath atomically:YES]; NSLog(@"-------2----%@",array); }

这篇文章是自己通过实践获取，在网上查过很多资料，也走了不上的弯路，由于刚开始学子不久，只是把自己遇到的问题贡献给大家

一，创建文件

//获取路径对象

NSArray*paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);

//获取完整路径

NSString*documentsDirectory = [pathsobjectAtIndex:0];

NSString*plistPath = [documentsDirectorystringByAppendingPathComponent:@"test.plist"];

NSMutableDictionary*dictplist = [[NSMutableDictionaryalloc]init];

//设置属性值

[dictplistsetObject:@"张三"forKey:@"name"];

[dictplistsetObject:@"李四"forKey:@"name1"];

[dictplistsetObject:@"王五"forKey:@"name2"];

//写入文件

[dictplistwriteToFile:plistPathatomically:YES];

这个是创建了一个简单的plist文件，创建后的图1为：

下面是创建了一种多键值的plist文件，代码和图如下：

//获取路径对象

NSArray*paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);

//获取完整路径

NSString*documentsDirectory = [pathsobjectAtIndex:0];

NSString*plistPath = [documentsDirectorystringByAppendingPathComponent:@"test.plist"];

NSMutableDictionary*dictplist = [[NSMutableDictionaryalloc]init];

//定义第一个插件的属性

NSMutableDictionary*plugin1 = [[NSMutableDictionaryalloc]init];

[plugin1setObject:@"张三"forKey:@"name1"];

[plugin1setObject:@"李四"forKey:@"name2"];

//定义第二个插件的属性

NSMutableDictionary*plugin2 = [[NSMutableDictionaryalloc]init];

[plugin2setObject:@"王五"forKey:@"name1"];

[plugin2setObject:@"赵斌"forKey:@"name2"];

//设置属性值

[dictplistsetObject:plugin1forKey:@"初一班"];

[dictplistsetObject:plugin2forKey:@"初二班"];

//写入文件

[dictplistwriteToFile:plistPathatomically:YES];

图2：

针对图1进行修改的程序，代码如下：

NSString*path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES) objectAtIndex:0]stringByAppendingPathComponent:@"test.plist"];

NSMutableDictionary*applist = [[[NSMutableDictionaryalloc]initWithContentsOfFile:path]mutableCopy];

NSString*name = [applistobjectForKey:@"name"];

name =@"山山";

[applistsetObject:nameforKey:@"name"];

[applistwriteToFile:pathatomically:YES];

执行后如下图：

针对图2进行修改的程序，代码如下：

[dictplist writeToFile:plistPath atomically:YES];

NSString*path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)objectAtIndex:0]stringByAppendingPathComponent:@"test.plist"];

//根据路径获取test.plist的全部内容

NSMutableDictionary*infolist= [[[NSMutableDictionaryalloc]initWithContentsOfFile:path]mutableCopy];

//获取初一班的信息

NSMutableDictionary*info = [infolistobjectForKey:@"初一班"];

NSString*name1 = [infoobjectForKey:@"name1"];

name1 =@"山山";

[infosetValue:name1forKey:@"name1"];

[infolistsetValue:infoforKey:@"初一班"];

[infolistwriteToFile:pathatomically:YES];

图如下：

以上两个修改信息的地方，必须要加入红色标记的方法，才能在表里进行增改操作。

以上是个人的学习心得，请大家多多指教。
