如何在iPhone中将NSString转换为CGPoint

Question

我从UITextfield获取值到NSString，需要将NSString的值转换为CGPoint，假设如果我在文本字段中输入6,5它应该将其转换为CGPoint。

Answer 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.
