Remove zeros from country code of phone number in Objective-C

Question
I want to remove the preceding zeros from phone number's country code. I take it as NSString because phone number contains symbols such as + , ( , ) , - . I need those symbols.
e.g
Input:-
1) NSString *phNo = @"0011234567890";
2) NSString *phNo2 = @"0601234567999";
Output:-
1) 11234567890
2) 601234567999
What I did is as follows
if ([phNo length]>10) {
NSString *countryCodeSubString = [phNo substringToIndex:[phNo length]-10];
if ([[countryCodeSubString substringToIndex:1]isEqualToString:@"0"]) {
for (int i=0; i<[countryCodeSubString length]; i++) {
NSString *str = [countryCodeSubString substringToIndex:i];
if ([str isEqualToString:@"0"]) {
str = [str stringByReplacingOccurrencesOfString:@"0" withString:@""];
}
}
}
}
I know above code is wrong. Can anybody help me with this ? How can I do this efficiently ?
Solution
OTHER TIPS
If you just want to get the preceding zeroes off, then you can do simply like this.
NSString *phNo = @"0011234567890";
float number = [phNo floatValue];
NSString *phNoWithOutZero = [NSString stringWithFormat:@"%1.0f", number];
But this will not work it the string have any special characters except number.
