使用SBJson或其他JSON库将对象转换为Json

使用

SBJson

proxyForJson

.h文件，

@interface MyCustomObject : NSObject {    NSString *receiverFirstName;    NSString *receiverMiddleInitial;    NSString *receiverLastName;    NSString *receiverLastName2;}@property (nonatomic, retain) NSString *receiverFirstName;@property (nonatomic, retain) NSString *receiverMiddleInitial;@property (nonatomic, retain) NSString *receiverLastName;@property (nonatomic, retain) NSString *receiverLastName2;- (id) proxyForJson;- (int) parseResponse :(NSDictionary *) receivedObjects;}

在实施文件中，

    - (id) proxyForJson {        return [NSDictionary dictionaryWithObjectsAndKeys: receiverFirstName, @"ReceiverFirstName", receiverMiddleInitial, @"ReceiverMiddleInitial", receiverLastName, @"ReceiverLastName", receiverLastName2, @"ReceiverLastName2", nil ];    }

为了从JSON字符串中获取对象，您必须编写这样的

parseResponse

- (int) parseResponse :(NSDictionary *) receivedObjects {    self.receiverFirstName = (NSString *) [receivedObjects objectForKey:@"ReceiverFirstName"];    self.receiverLastName = (NSString *) [receivedObjects objectForKey:@"ReceiverLastName"];         NSString *middleName = (NSString *) [receivedObjects objectForKey:@"ReceiverMiddleInitial"];    if ((NSNull *) middleName == [NSNull null]) {        self.receiverMiddleInitial = @"";    } else {        self.receiverMiddleInitial = middleName;    }    NSString *lastName2 = (NSString *) [receivedObjects objectForKey:@"ReceiverLastName2"];    if ((NSNull *) lastName2 == [NSNull null]) {        self.receiverLastName2 = @"";    } else {        self.receiverLastName2 = lastName2;    }    return 0;}
