I am using something like this example as my base if you want to look at the code:
Advanced RSS Reader
And i am working with GTMNSString+XML and GTMNSString+HTML.
my problem is in RSSItem.m.
it already includes GTMNSString+HTML.I added GTMNSString+XML.
if i use gtm_stringBySanitizingAndEscapingForXML it does what it needs to do
NSString* description = [NSString stringWithFormat:#"%#...", [self.description substringToIndex:100]];
description = [description gtm_stringBySanitizingAndEscapingForXML];
If i do gtm_stringByUnescapingFromHTML it also does it.
NSString* description = [NSString stringWithFormat:#"%#...", [self.description substringToIndex:100]];
description = [description gtm_stringByUnescapingFromHTML];
What i want to do is combine it so that it goes through both gtm_stringByUnescapingFromHTML and gtm_stringBySanitizingAndEscapingForXML. I tried to do this but it didn't work:
description = [[description gtm_stringBySanitizingAndEscapingForXML] gtm_stringByUnescapingFromHTML];
Try like this:-
NSString* description1 = [NSString stringWithFormat:#"%#...", [self.description substringToIndex:100]]; description = [description gtm_stringBySanitizingAndEscapingForXML];
NSString* description2 = [NSString stringWithFormat:#"%#...", [self.description substringToIndex:100]];
description = [description gtm_stringByUnescapingFromHTML];
NSString* finalString=[description1 stringByAppendingString:description2];
NSLog(#"%#",finalString);

I have a string like this: "/Myapp/auth/hrHeadcount+ME+All IOU+Headcount+Grade" and I want to save only the "HeadCount" in another string. How can I do that?
NSString *srcStr = #"/Myapp/auth/hrHeadcount+ME+All IOU+Headcount+Grade";
NSString *dstStr = [[srcStr componentsSeparatedByString:#"+"] objectAtIndex:3];
If you are sure it will have same format then u can do the following
NSString *string1 = #"/Myapp/auth/hrHeadcount+ME+All IOU+Headcount+Grade";
NSArray *stringArray = [string1 componentsSeparatedByString:#"/"];
NSString *string2 = stringArray[3];
NSArray *finalArray = [string2 componentsSeparatedByString:#"+"];
NSString *finalString = finalArray[0];
final String will have the headCount u require
for example i have string like this:
NSString *one = B3#This is the first string
NSString *two = 1#This is the second string
How can i get the "B3" and "1" Character only (using objective C)
Thanks..
Turns out this is one way to do it:
NSRange range = [one rangeOfString:#"#" options:NSBackwardsSearch];
NSString *newString = [one substringToIndex:range.location];
Thanks for all the answers.
NSString* one = #"B3#";
NSString* two = #"1#";
NSString* result = [one stringByReplacingOccurrencesOfString:#"#" withString:#""];
NSString* result_2 = [two stringByReplacingOccurrencesOfString:#"#" withString:#""];
//if you need to marge
NSString* tot = [NSString stringWithFormat:#"%#%#",result,result_2];
I need to concatenate a string and a variable together - I kind of find lots of examples of adding a string prior to a variable but not the other way round - how do I do this?
NSString *theImage = [[self.detailItem valueForKey:#" resimagefiletitle"] description], #"'add on the end";
Something like this:
NSString *theImage = [NSString stringWithFormat:#"%# %#",[self.detailItem valueForKey:#" resimagefiletitle"], #"'add on the end"];
Or:
NSString *theImage = [NSString stringWithFormat:#"%# add on the end",[self.detailItem valueForKey:#" resimagefiletitle"]];
Try this
NSString *theImage = [NSString stringWithFormat:#"%# '>",[[self.detailItem valueForKey:#"resimagefiletitle"] description]];
Here I am considering [[self.detailItem valueForKey:#"resimagefiletitle"] description] gives NSString
We can concat diffrent type of datatypes into string by mention the format for it.
like if your want to concat two or more strings together then you can use the following code:
NSString *NewString = [NSString stringWithFormat:#"%#%#",#"This Is",#"way to concate string"];
and if your want concat integer value then you can mention the data format for it "%i".
eg:
int OutOf = 150;
NSString *NewString = [NSString stringWithFormat:#"%#%i",#"I got 100 out of ",OutOf];
this may help you.
I've got a string that shows the stock amount using "-" as separators.
It's built up like this: localStock-wareHouseStock-supplierStock
Now I want to update the supplierStock at the end of the string, but as you can see in the code below it goes wrong when the original string returns more than a single-space value (such as 20).
Is there a way to remove all characters until the last "-" (or remove characters after the second "-")?
NSMutableString *string1 = [NSMutableString stringWithString: p1.colorStock];
NSLog(#"string1: %#",string1);
NSString *newString = [string1 substringToIndex:[string1 length]-2];
NSLog(#"newString: %#",newString);
NSString *colorStock = [NSString stringWithFormat:#"%#-%#",newString,p2.supplierStock];
NSLog(#"colorstock: %#",colorStock);
p1.colorStock = colorStock;
NSLog1
string1: 0-0-0
newString: 0-0
colorstock: 0-0-20
NSLog2
string1: 0-0-20
newString: 0-0-
colorstock: 0-0--20
EDIT: Got it working thanks to Srikar!
NSString *string1 = [NSString stringWithString: p1.colorStock];
NSLog(#"string1: %#",string1);
NSString *finalString = [string1 stringByReplacingOccurrencesOfString:[[string1 componentsSeparatedByString:#"-"] lastObject] withString:p2.supplierStock.stringValue];
NSLog(#"finalString: %#",finalString);
p1.colorStock = finalString;
Why not use componentsSeparatedByString followed by lastObject ?
NSString *supplierStock = [[string1 componentsSeparatedByString:#"-"] lastObject];
The above works if the "stock amount" is always in sets of 3's separated by a "-". Also since you always want supplierStock, lastObject is perfect for your needs.
Of course after splitting string1 with - you get a NSArray instance and you can access the individual components using objectAtIndex:index. So if you want localStock you can get by
NSString *localStock = [[string1 componentsSeparatedByString:#"-"] objectAtIndex:0];
I would suggest splitting the string into the 3 parts using [NSString componentsSeparatedByString:#"-"] and then building it back up again:
NSArray *components = [p1.colorStock componentsSeparatedByString:#"-"];
p1.colorStock = [NSString stringWithFormat:#"%#-%#-%#",
[components objectAtIndex:0],
[components objectAtIndex:1],
p2.supplierStock];
With a string that looks like
NSString *myString = #"Hello-World";
you can separate it with the componentsSeparatedByString: method of the NSString object as
NSArray *myWords = [myString componentsSeparatedByString:#"-"];
The myWords - array will then contain the two NSString objects Hello and World.
To access the strings:
NSString *theHelloString = [myWords objectAtIndex:0];
NSString *theWorldString = [myWords objectAtIndex:1];
Hope it helps!
None of these examples show how to do this if you are unaware of how many of these separator occurrences you're going to have in the original string.
Here's what I believe the correct the correct code should be for dismantling the original string and rebuilding it until you reach the final separator, regardless of how many separators it contains.
NSString *seperator = #" ";
NSString *everythingBeforeLastSeperator;
NSArray *stringComponents = [originalString componentsSeparatedByString:seperator];
if (stringComponents.count!=0) {
everythingBeforeLastSeperator = [stringComponents objectAtIndex:0];
for (int a = 1 ; a < (stringComponents.count - 1) ; a++) {
everythingBeforeLastSeperator = [NSString stringWithFormat:#"%#%#%#", everythingBeforeLastSeperator, seperator, [stringComponents objectAtIndex:a]];
}
}
return everythingBeforeLastSeperator;

How could I write this if else code checking in a better way?
My conditional code here seems repetitive and long. Is there a better approach? I want to test for a string value in a NSDictionary object and then depending upon the value prefix a UILabel with $, £, ¥ currency symbols.
Here's my code (I've just shown 2 examples below, I have more currencies and the code is very long):
if ([[item objectForKey:#"currency"] isEqualToString:#"EUR"]) {
NSString *priceConvertToStr = [NSString stringWithFormat:#"€%#", [[item objectForKey:#"price"]stringValue]];
NSString *priceStringFix = [priceConvertToStr
stringByReplacingOccurrencesOfString:#"(null)" withString:#""];
priceLabelText.text = priceStringFix;
[imgView2 addSubview:priceLabelText];
}
if ([[item objectForKey:#"currency"] isEqualToString:#"GBP"]) {
NSString *priceConvertToStr = [NSString stringWithFormat:#"€%#", [[item objectForKey:#"price"]stringValue]];
NSString *priceStringFix = [priceConvertToStr
stringByReplacingOccurrencesOfString:#"(null)" withString:#""];
priceLabelText.text = priceStringFix;
[imgView2 addSubview:priceLabelText];
}
if ([[item objectForKey:#"currency"] isEqualToString:#"USD"]) {
NSString *priceConvertToStr = [NSString stringWithFormat:#"$%#", [[item objectForKey:#"price"]stringValue]];
NSString *priceStringFix = [priceConvertToStr
stringByReplacingOccurrencesOfString:#"(null)" withString:#""];
priceLabelText.text = priceStringFix;
[imgView2 addSubview:priceLabelText];
}
thanks so much for any help.
You can refactor your code to this (possible because essentially 80% of the code within the if statements are identical):
NSDictionary *currDict = #{
#"EUR": #"€",
#"GBP": #"₤",
#"USD": #"$"
};
NSString *currName = [item objectForKey:#"currency"];
NSString *currency = [currDict objectForKey:currName];
NSString *priceConvertToStr = [NSString stringWithFormat:#"%#%#",
currency,
[[item objectForKey:#"price"] stringValue]
];
NSString *priceStringFix = [priceConvertToStr stringByReplacingOccurrencesOfString:#"(null)" withString:#""];
priceLabelText.text = priceStringFix;
[imgView2 addSubview:priceLabelText];
