I have a UIWebView set to scale to fit in an iPad app that gets its content from and NSString. If I turn off scale to fit the text is bigger, although would like it to be much bigger, but I lose the zooming feature.

Hi, I am trying to calculate the closest text position in a string (text of UITextView) from a CGPoint. I wonder if some methods in NSString are useful for this?

I have written this function which shuffles the contents of a NSString, and it seems to work, but every now and then it crashes. This may be a roundabout way, but I put the characters into an array, swap the elements in the array randomly, and then turn the array back into a string. I'm not sure what I am doing that is unsafe which make...
I would like to know how, in Objective-C, how to tell if a string represents a boolean value. The [string boolValue] method will not work, because when I try to parse a string like [@"ERROR" boolValue] it returns NO instead of throwing an exception. In C#, I could do something like: if (Boolean.TryParse(string, out bool)), but this is no...

It is getting its values from a database and I want the text in the database to be rendered with breaks within the text. I tried using "\n" to do this but it gets rendered as text.

Hi there. I use NSURLConnection to get the contents of a plist file from a remote server. On connection:didRecieveData: I add the latest data to an NSMutableString. Now my problem is adding this data to an array. So you have arrayWithContentsOfURL - which is synchronous - but i suppose I could just add the contents of the NSString to ...
Both the following resolve to True: 1) @"foo" == @"foo" (is True) 2) NSString *myString1 = @"foo"; NSString *myString2 = @"foo"; myString1 == myString2 (is True) However, there are definitely times where two NSStrings cannot be compared using the equality operator, and [myString1 isEqualToString:myString2] is required instead. Ca...
Hi! I am struggling with very simple thing: I receive some ids by http request as a string. I know they represent 64bit integer id numbers. How can I convert them to the 64 bit Integers (NSNumber or NSInteger)? Functions like: [nsstring integerValue], [nsstring intValue] seems to be 32bit limited (max value:2147483647). Any Hints? ...
Hi, I read data from a TCP socket connection, but the server sends me \0 from time to time (which would mark the end of a message). Thus, I do not get the rest of the message. I read like this: uint8_t buf[tcpBufferSize]; unsigned int len = 0; len = [inputStream read:buf maxLength:tcpBufferSize]; if(len > 0) { NSMutableData* dat...

I am displaying source code in a NSTextView - example: <html> <head> <title>test</title> </head> <body>hello!</body> </html> The code above can vary in size, but what should I do if I wanted to insert say <link rel="apple-touch-icon" href="webclip.pn...

I love the shorthand handling of string literals in Objective C with the @"string" notation. Is there any way to get similar behavior with NSNumbers? I deal with numbers more and it's so tedious having [NSNumber numberWithWhatever:] calls everywhere. Even creating a macro would work, but my knowledge of how best to do that is limited. ...
Hi, I have a need to convert NSString to double. If this string is in essence integer, then result is OK. If string is decimal, perhaps also with group separators then results are false. Any king of separator (whether "." or ",") whis is first in the string is always used as decimal separator. I have tried to do something with NSScanne...
