IOS沙盒

可以先在程序打印沙盒路径：

NSLog(@"路径%@",NSHomeDirectory());

 

----------------------------------------------------其中一个沙盒存储更新与读取方法方法------------------------------------------------------

 

 

#import <Foundation/Foundation.h>

 

@interface ConfigData : NSObject

 

//保存到沙盒中

 

+ (void)saveCache:(NSString *)keyName andString:(NSString *)str;

 

//从沙盒中读取

 

+ (NSString *)getCache:(NSString *)keyName;

 

@end

 

 

#import "ConfigData.h"

 

@implementation ConfigData

 

+ (void)saveCache:(NSString *)keyName andString:(NSString *)str

 

{

 

    NSUserDefaults * setting = [NSUserDefaultsstandardUserDefaults];

 

    NSString * key = [NSStringstringWithFormat:@"OrderId-%@",keyName];

 

    [setting setObject:str forKey:key];

 

    [setting synchronize];

 

}

 

 

 

+ (NSString *)getCache:(NSString *)keyName

 

{

 

    NSUserDefaults * settings = [NSUserDefaultsstandardUserDefaults];

 

    NSString *key = [NSStringstringWithFormat:@"OrderId-%@",keyName];

 

    NSString *value = [settings objectForKey:key];

 

    return value;

 

}

 

@end
