How to Convert NSString into CGPoint in iPhone

问题:

I am getting the values from UITextfield into NSString , need to convert the values of NSString into CGPoint, Suppose if i enter 6,5 into textfield it should covert it into CGPoint.

回答1:

See CGPointFromString (documentation in link). The string has to be in the format {x,y} so you would need to add those to the user input yourself:

CGPoint myPoint = CGPointFromString([NSString stringWithFormat:@"{%@}",textField.text]);

Will return CGPointZero if the string is invalid.
