Question

我使用以下代码解析了Json

- (void) getWorkingCalendar:(NSData *)dataForParse{

    NSMutableArray *locations = [[NSMutableArray alloc] init];

    NSString* myString;
    myString = [[NSString alloc] initWithData:dataForParse encoding:NSASCIIStringEncoding];

    NSLog(@"data is %@", myString);

    NSArray * parsedData = [NSJSONSerialization JSONObjectWithData:dataForParse options:kNilOptions error:nil];

    NSLog(@"parser data %@", parsedData);


    for (NSDictionary *dict in parsedData) {


        NSLog(@"Value is %@", dict);

    }

    [delegate array:locations];


}

输出如下

2014-04-30 12:44:41.828 Testing[827:60b] parser data (
    "/Date(1399016682788+0400)/",

如何从NSDictionary获取NSString中的时间段？

先谢谢。

您可能需要稍微调整一下，但这是我在这些日期中使用的内容：

标题文件

@interface NSDate (JSON)

+ (NSDate *)dateFromJSON:(NSString *)dateString;

@end

<强>实施

#import "NSDate+JSON.h"

@implementation NSDate (JSON)

+ (NSDate *)dateFromJSON:(NSString *)dateString {

    if (dateString == nil || [dateString isKindOfClass:[NSNull class]]) {
        return nil;
    }

    NSString *header = @"/Date(";
    NSRange headerRange = [dateString rangeOfString:header];
    if (headerRange.location != 0) {
        return nil;
    }

    NSString *footer = @")/";
    NSRange footerRange = [dateString rangeOfString:footer options:NSBackwardsSearch];
    if (footerRange.location == NSNotFound || footerRange.location + footerRange.length != dateString.length) {
        return nil;
    }

    NSString *timestampString = [dateString substringWithRange:NSMakeRange(headerRange.length, footerRange.location - headerRange.length)];

    NSTimeInterval interval = [timestampString doubleValue] * 0.001;
    return [NSDate dateWithTimeIntervalSince1970:interval];
}

@end

此示例不包含您日期中的时区，因此您可能希望添加该时区。

然后使用它：

for (NSString *dateValue in parsedData) {
     NSDate *date = [NSDate dateFromJSON:dateValue];
}
