I can only guess, but please correct me if I am wrong: [encoder encodeValueOfObjCType:@encode(NSDecimal) at:&theDecimal]; where encoder is an instance of NSCoder. But one thing is strange: Why is there no key to provide? How would I get that back then, without a key? ...

I am not sure about this: // assume value is a NSDecimal type and exists NSDecimalNumber *decNum = [[NSDecimalNumber alloc] initWithDecimal:value]; [encoder encodeObject:decNum forKey:@"someKey"]; [decNum release]; I'm wrapping the NSDecimal into an NSDecimalNumber object. I have to release it somewhere. But I am not sure... does the ...

Hi...I have an UIButton, which logs the content that is present in a couple of UITextField's.But when I click on this UIButton thrice, the simulator hangs and the debugger is opened. Can someone tell me why is this happening. It happens only when there is content in UITextFields. ...
I have an NSDecimal in a tight calculations loop, where I need to floor the value. I want to prevent creating fat NSDecimalNumber objects just for that. Is there a cost-efficient way to get a floor? That floor is just needed to calculate how many times another value might fit in there, with no rest. The NSDecimal API doesn't provide some...
I wanted to know, the best methodology (with code sample please) of having a login feature on an iPhone application, that would connect to a server. I am assuming web service sending via SOAP isn't the safest. Thanks guys ...

It's been a while since I messed with my TableViewController so I'm a bit rusty...but now I'd like to set it up so that when a section has zero rows to display (array is empty) then it will "lie" to the controller and return 1 for numberOfRowsInSection. Then in the cellForRowAtIndexPath it will place a UILabel over the one row's cell tha...
The documentation confuses me about this. They say: void NSDecimalCompact ( NSDecimal *number ); Discussion Formats number so that calculations using it will take up as little memory as possible. All the NSDecimal... arithmetic functions expect compact NSDecimal arguments. The last part is important: All the NSD...
For example, I try to do something like this: - (BOOL)compare:(NSDecimal)leftOperand greaterThan:(NSDecimal)rightOperand { BOOL returnValue = NO; NSComparisonResult result = NSDecimalCompare(&leftOperand, &rightOperand); if (result == NSOrderedDescending) { // if the left operand is greater than the right operand return...
For example: - (BOOL)compare:(NSDecimal)leftOperand greaterThan:(NSDecimal)rightOperand { NSComparisonResult result = NSDecimalCompare(&leftOperand, &rightOperand); // rest not important } like you can see, the method just receives these two types of NSDecimal, leftOperand and rightOperand. Then it passes them on to a C API fu...

Hi, I am using a UITextView and enabling paging (in both IB and programatically toggling it on and off). There's a lot of text and when scrolling with paging enabled sometimes the first and/or last line of the currently viewable text ends up halfway in view and half out of view at the bottom or top of the frame so you can only see the t...
