There were two problems that I ran into: The CFURLCreateStringByAddingPercentEscapes method apparently isn’t completely fool proof. [NSString stringWithFormat] gets messy with a lot of parameters. So I created a class to trivialize the handling of this circumstance. #import <Foundation/Foundation.h> @interface UrlParameterBuilder : NSObject { NSMutableDictionary* parameters; } -(UrlParameterBuilder*)init; -(UrlParameterBuilder*)initWithParameterDictionary:(NSDictionary*)parameterDictionary; -(void)addParamWithTitle:(NSString*)title andValue:(NSString*)value; -(NSString*)getUrlString; @end #import "URLParameterBuilder.h" @implementation UrlParameterBuilder -(UrlParameterBuilder*)init { self = [super init]; parameters = [NSMutableDictionary dictionary]; return self; } -(UrlParameterBuilder*)initWithParameterDictionary:(NSDictionary*)parameterDictionary { self = [super init]; parameters = [NSMutableDictionary dictionaryWithDictionary:parameterDictionary]; return self; } -(void)addParamWithTitle:(NSString*)title andValue:(NSString*)value { [parameters setObject:value forKey:title]; } -(NSString*)getUrlString { NSMutableString* result = [NSMutableString string]; BOOL firstIterationComplete = NO; for (NSString* key in parameters) { [result appendFormat:@"%c%@=%@", firstIterationComplete ?
