如何将24小时字符串时间转换为12小时字符串格式
问题描述：
我在NSString中有时间，例如"15:15"
I have time in NSString like "15:15"
我想将此NSString时间隐藏为12个小时的NSString(即"3:15 PM").
I want to covert this NSString time into 12 hr NSString(i.e "3:15 PM").

使用NSDateFormatter将字符串转换为NSDate.然后再次使用dateformatter将NSDate更改为字符串.
Use NSDateFormatter to turn the string in a NSDate. Then use the dateformatter again to change the NSDate to a string.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"HH:mm";
NSDate *date = [dateFormatter dateFromString:@"15:15"];
dateFormatter.dateFormat = @"hh:mm a";
NSString *pmamDateString = [dateFormatter stringFromDate:date];
代码可能包含一些错误，这些错误未经编译或测试就可以编写.
