Enumeration Issue

开发者 https://www.devze.com 2023-03-18 20:14 出处:网络
NSMutableArray *tempMutableArray = [[NSMutableArray alloc] init]; if (street != NULL) { [tempMutableArray addObject:(NSString *)street];
NSMutableArray *tempMutableArray = [[NSMutableArray alloc] init];
if (street != NULL) {
[tempMutableArray addObject:(NSString *)street];
}
if (city != NULL) {
[tempMutableArray addObject:(NSString *)city];
}
if (state != NULL) {
[tempMutableArray addObject:(NSString *)state];
}                    
if (zip != NULL) {
[tempMutableArray addObject:(NSString *)zip];
}
if (country != NULL) {
// Check to see if the country is USA/Canada
NSStringCompareOptions  compareOptions = NSDiacriticInsensitiveSearch;
NSArray* countryIndex = [[NSArray alloc] initWithObjects:@"United States of America", @"United States", @"U.S.A.", @"USA", @"US", @"U.S.", @"Canada", @"CAN", @"CDN", @"CA", nil];

for (NSString* element in countryIndex) 
{
NSComparisonResult result = [(NSString *)country compare:element options:compareOptions];
if (NSOrderedSame == result) {
// Do another thing here if they match...
CFRelease(country);
country = CFStringCreateWithCString(NULL, "", kCFStringEncodingUTF8);
}
else {
// Try something else...
[tempMutableArray addObject:(NSString *)country];
}
}
}
for (NSString* element in tempMutableArray) 
{
    syntheticAddress = [syntheticAddress stringByAppendingString:[NSString stringWithFormat:@"%@ ,", element]];
NSLog(@"synthetic address is %@", syntheticAddress);
}

The problem is that the the output is getting excessive entries

I would like the output to only be

Your NSLog is inside the for loop.

EDIT :

for (NSString* element in countryIndex) 
{
      NSComparisonResult result = [(NSString *)country compare:element options:compareOptions];
      if (NSOrderedSame == result) {
              // Do another thing here if they match...
              CFRelease(country);
              country = CFStringCreateWithCString(NULL, "", kCFStringEncodingUTF8);
       }
       else {
          // Try something else...
          [tempMutableArray addObject:(NSString *)country];
       }
 }

Look at the code above. Your if condition will only succeed once (I'm assuming ) .. but your else condition will hit for all the other non-matches. And each time it fails, you are adding a country object to your tempMutableArray. Is this what you want?

EDIT 2: This should be the correct way of doing it.

for (NSString* element in countryIndex) 
{
      NSComparisonResult result = [(NSString *)country compare:element options:compareOptions];
      if (NSOrderedSame == result) {
          [tempMutableArray addObject:(NSString *)country];
          break;
       }
       else {
          // Try something else...
          // No match. Go on to the next element compare.
       }
 }
