iOS时间戳字符串NSdate转换demo

1 在项目中我们经常要做时间格式的转换，以下是我封装的NSDate+TimeCategory，希望帮助到大家。

#import <Foundation/Foundation.h>@interface NSDate (TimeCategory)/** * 字符串转NSDate * * @param theTime 字符串时间 * @param format 转化格式如yyyy-MM-dd HH:mm:ss,即2015-07-15 15:00:00 * * @return <#return value description#> */+ (NSDate *)dateFromString:(NSString *)timeStrformat:(NSString *)format;/** * NSDate转时间戳 * * @param date 字符串时间 * * @return 返回时间戳 */+ (NSInteger)cTimestampFromDate:(NSDate *)date;/** * 字符串转时间戳 * * @param theTime 字符串时间 * @param format 转化格式如yyyy-MM-dd HH:mm:ss,即2015-07-15 15:00:00 * * @return 返回时间戳的字符串 */+(NSInteger)cTimestampFromString:(NSString *)timeStrformat:(NSString *)format;/** * 时间戳转字符串 * * @param timeStamp 时间戳 * @param format 转化格式如yyyy-MM-dd HH:mm:ss,即2015-07-15 15:00:00 * * @return 返回字符串格式时间 */+ (NSString *)dateStrFromCstampTime:(NSInteger)timeStampwithDateFormat:(NSString *)format;/** * NSDate转字符串 * * @param date NSDate时间 * @param format 转化格式如yyyy-MM-dd HH:mm:ss,即2015-07-15 15:00:00 * * @return 返回字符串格式时间 */+ (NSString *)datestrFromDate:(NSDate *)datewithDateFormat:(NSString *)format;@end#import "NSDate+TimeCategory.h"static NSDateFormatter *dateFormatter;@implementation NSDate (TimeCategory)+(NSDateFormatter *)defaultFormatter{static dispatch_once_t onceToken;dispatch_once(&onceToken, ^{dateFormatter = [[NSDateFormatter alloc]init];});return dateFormatter;}+ (NSDate *)dateFromString:(NSString *)timeStrformat:(NSString *)format{NSDateFormatter *dateFormatter = [NSDate defaultFormatter];[dateFormatter setDateFormat:format];NSDate *date = [dateFormatter dateFromString:timeStr];return date;}+ (NSInteger)cTimestampFromDate:(NSDate *)date{ return (long)[date timeIntervalSince1970];}+(NSInteger)cTimestampFromString:(NSString *)timeStrformat:(NSString *)format{NSDate *date = [NSDate dateFromString:timeStr format:format];return [NSDate cTimestampFromDate:date];}+ (NSString *)dateStrFromCstampTime:(NSInteger)timeStampwithDateFormat:(NSString *)format{NSDate *date = [NSDate dateWithTimeIntervalSince1970:timeStamp];return [NSDate datestrFromDate:date withDateFormat:format];}+ (NSString *)datestrFromDate:(NSDate *)datewithDateFormat:(NSString *)format{NSDateFormatter* dateFormat = [NSDate defaultFormatter];[dateFormat setDateFormat:format];return [dateFormat stringFromDate:date];}

2调用

#import "NSDate+TimeCategory.h"

– (IBAction)strToDate:(id)sender {NSString *timeStr = @"2015-07-15 15:00:00";NSDate *date = [NSDate dateFromString:timeStr format:@"yyyy-MM-dd HH:mm:ss"];NSLog(@"字符串转NSDate：%@ -> %@",timeStr,date);}- (IBAction)dateToStamp:(id)sender {NSDate *date = [NSDate date];NSInteger stamp = [NSDate cTimestampFromDate:date];NSLog(@"NSDate转时间戳：%@ ->%ld",date,stamp);}- (IBAction)strToStamp:(id)sender {NSString *timeStr = @"2015-07-15 15:00:00";NSInteger stamp = [NSDate cTimestampFromString:timeStr format:@"yyyy-MM-dd HH:mm:ss"];NSLog(@"字符串转时间戳：%@ -> %ld",timeStr,stamp);}- (IBAction)stampToStr:(id)sender {NSInteger stamp = 1436943600;NSString *timeStr = [NSDate dateStrFromCstampTime:stamp withDateFormat:@"yyyy-MM-dd HH:mm:ss"];NSLog(@"时间戳转字符串：%ld ->%@",stamp,timeStr);}- (IBAction)dateToStr:(id)sender {NSDate *date = [NSDate date];NSString *timeStr = [NSDate datestrFromDate:date withDateFormat:@"yyyy-MM-dd HH:mm:ss"]; NSLog(@"NSDate转字符串：%@ ->%@",date,timeStr);}分别得到以下结果
