在float中删除小数点前的前导零

Question

我试图删除xcode中两位小数位浮点数的前导零。

arrFraction = [[NSMutableArray alloc] init];
for (float fraction = .00; fraction <=.99; fraction+= .01) {
    NSString *fractionString = [NSString stringWithFormat:@"%.2f%", fraction];
    [arrFraction addObject:fractionString];
}

这导致NSMutableArray的值为0.00，但0.99

我想要的是.00到.99

Answer 1

尝试这样，

    NSString *str =@"0000.00013200";
    NSRange range = [str rangeOfString:@"^0*" options:NSRegularExpressionSearch];
    str= [str stringByReplacingCharactersInRange:range withString:@""];
    NSLog(@"%@",str);

O / P： - .00013200
