格式为 00:00:00 的 iOS 数组字符串到格式为 00.00.00 的数组浮点型 Objective C

Question

我正在寻找如何将数组字符串转换为数组浮点数，数组字符串的格式为 00:00:00 (hh:mm:ss) 而数组浮点数是 00.00.00 原因是因为数组浮点数是在一个图表现在我只有这个

example array
   TimeRunning = @[@"01:10:50", @"01:03:23", @"03:04:22"];//arrayStrig

真正的代码是

timeRunning = [obj valueForKey:@"oficialTime"];
NSLog(@"%@",timeRunning); //out 01:02:03 10:10:02 10:38:59

float ofcTime =[[obj valueForKey:@"oficialTime"]floatValue];
NSLog(@"float : %f",ofcTime); //out 1.000000 10.000000 10.000000

我试试这个

NSString * dataString = [TimeRunningString stringByReplacingOccurrencesOfString:@":" withString:@"."];
NSLog(@"??????: %@",dataString); //out 01.02.03  10.10.02  10.38.59

NSArray *listItems = [dataString componentsSeparatedByString:@"."];
NSLog(@"Real: %@",listItems);//out  10,
                                    10,
                                    02

NSString *covert = [NSString stringWithFormat:@"%@",listItems];
NSLog(@":%@",covert);   //out  10,
                               10,
                               02

float realArrary = [dataString floatValue];
NSLog(@"floatP : %f",realArrary); out 2.030000 10.000000 10.100000

Answer 1

试试

 NSString *dateString = [obj valueForKey:@"oficialTime"];
 NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
 [dateFormatter setDateFormat:@"hh:mm:ss.SSS"];
 NSDate *dateFromString = [[NSDate alloc] init];
 dateFromString = [dateFormatter dateFromString:dateString];
 NSLog(@"%@",dateString); //Out 02:03:03

然后

NSString * dataString = [TimeRunningString stringByReplacingOccurrencesOfString:@":" withString:@""];             float Realarrary = [dataString floatValue];
NSLog(@"floatP: %0.0f",Realarrary); //Out 20303

 now you have string 02:03:03 to float 20303
