As your dataset clearly has garbage values, You can use this method to check if your string is valid or not. Define your validation criteria and simply don't entertain the values

I'm trying to encode and decode base64 data. but while decoding the base64 data, it returns bunch of hex values, but i couldn't display or printout using NSlog to the original readable strings. The below code couldn't print anything, just empty. Can anyone help ? thanks > > NSString* msgEncoded = [[NSString alloc] initWithFormat:@"Q1NNKE1DTC9TTUEgUkNWL2FkbWluQHNldGVjcy5jb20gT1JHLyBUVkIvNDNkYzNlMzQwYWQ3Yzkp:"]; NSData* decoded = [[NSData alloc] initWithData:[self decodeBase64WithString:msgEncoded]]; NSString* plainString = [[NSString alloc]initWithData:decoded encoding:NSUTF8StringEncoding];

I have an NSString as follows: <img alt="996453912" src="http://d2gg0uigdtw9zz.cloudfront.net/large/996453912.jpg" /><a href="http://www.dealcatcher.com/shop4tech-coupons">Shop4Tech Coupons</a> I only need the first part (before the <a href part), and I cannot figure out how to remove the second part. I have tried a ton, but it has not worked. Use something like: NSRange rangeOfSubstring = [string rangeOfString:@"<a href"]; if(rangeOfSubstring.location == NSNotFound) { // error condition — the text '<a href' wasn't in 'string' } // return only that portion of 'string' up to where '<a href' was

In Objective-C, the method stringWithFormat: seems to be extremely slow and is actually a large bottleneck in one of our apps (we used the profiler to find that out). Is there a way to optimise it or use some faster C code? Yes use sprintf in c http://www.cplusplus.com/reference/cstdio/sprintf/ after that push the char* in a NSString with [NSString stringWithUTF8:]; example: char cString[255]; sprintf (cString, "%d", 36); NSString* OCstring = [[NSString alloc] initWithUTF8String:cString]; If you're doing extensive string manipulations and operations - it sounds like you might well be doing so,

I'm having a problem doing something with NSString stringWithFormat... The problem is as follows: First of all, I have 2 strings. Which are money quantities. The thing, is that i want to create 1 string with these two. For ex: strF = [NSString stringWithFormat:@"First: %@ Second: %@", value1, value2]; I want to know if there is possible to make a correct padding between First and Second.. Assuming the first string is not the same length always.. I want to make this: First: 10,000.00 Second: 788.00 First: 10.00 Second: 788.00 First: 0.00 Second: 788.00 First: 100.00 Second: 788.00 First: 5.00

for example, I have NSString *myClass = @"RootViewController" How do I get class from NSString? Try this id obj= [[NSClassFromString(@"RootViewController") alloc] init]; You can use Class class = NSClassFromString(@"RootViewController"); NSClassFromString Obtains a class by name. Class NSClassFromString ( NSString *aClassName ); Parameters aClassName The name of a class. Return Value The class object named by aClassName, or nil if no class by that name is currently loaded. If aClassName is nil, returns nil. Availability Available in iOS 2.0 and later. There is a lot of methods like this in
