In my app. When user click on registration in safari browser I am returning to app. In app I am getting url: myApp://[email protected]
I want to fetch value of email from this url. How to do that.?
I have done this but this is giving me error that no key value email found:
NSString *str=[url valueForKey:@"email"];
URLParser *parser = [[[URLParser alloc] initWithURLString:@"myApp://[email protected]"] autorelease];
NSString *emailVal = [parser valueForVariable:@"email"];
Use NSScanner class given below
URLParser.h
@interface URLParser : NSObject {
NSArray *variables;
}
@property (nonatomic, retain) NSArray *variables;
- (id)initWithURLString:(NSString *)url;
- (NSString *)valueForVariable:(NSString *)varName;
@end
URLParser.m
@implementation URLParser
@synthesize variables;
- (id) initWithURLString:(NSString *)url{
self = [super init];
if (self != nil) {
NSString *string = url;
NSScanner *scanner = [NSScanner scannerWithString:string];
[scanner setCharactersToBeSkipped:[NSCharacterSet characterSetWithCharactersInString:@"&?"]];
NSString *tempString;
NSMutableArray *vars = [NSMutableArray new];
[scanner scanUpToString:@"?" intoString:nil]; //ignore the beginning of the string and skip to the vars
while ([scanner scanUpToString:@"&" intoString:&tempString]) {
[vars addObject:[tempString copy]];
}
self.variables = vars;
[vars release];
}
return self;
}
- (NSString *)valueForVariable:(NSString *)varName {
for (NSString *var in self.variables) {
if ([var length] > [varName length]+1 && [[var substringWithRange:NSMakeRange(0, [varName length]+1)] isEqualToString:[varName stringByAppendingString:@"="]]) {
NSString *varValue = [var substringFromIndex:[varName length]+1];
return varValue;
}
}
return nil;
}
- (void) dealloc{
self.variables = nil;
[super dealloc];
}
@end

NSURL pull out a single value for a key in a parameter string
This is what you actually required.
All the best
Try with URL.query,
NSString *str=url.query;
Where Url is object of NSUrl.
You can also use following code.
NSString *strComplete = @"myApp://[email protected]";
NSArray *array = [strComplete componentsSeparatedByString:@"?"];
NSLog(@"%@",array);
NSString *strSecond = [array objectAtIndex:1];
NSLog(@"%@",strSecond);
Try this if it helps to you.
