如何将uitextfield整数转换为字符串

Question

I am new to iOS. I need to convert textfield integer value into string. I created textfield name as value1 and string as str1 .

str1 = [NSString stringWithFormat:@"%d", value1];

By default, UITextField returns a NSString value.

So you can get any value like this :

NSString *str1 = value1.text;

As simple as that, but if you want to convert it to Int then,

int strInt = str1.intValue;
NSInteger strInteger = str1.integerValue;

If want to converts to a Double value,

double strDouble = str1.doubleValue;
CGFloat strCGFloat = str1.doubleValue;

And yes, if you don't need to perform anything on str1 then you shouldn't need to create an instance, you can directly convert it like this.

int strInt = value1.text.intValue;
NSInteger strInteger = value1.text.intValue;
