#1

Follow this tip, then add the two NSNumbers.

按照这个提示，然后添加两个NSNumbers。

NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber * myNumber = [f numberFromString:ftext];
NSNumber * myNumber2 = [f numberFromString:ftext2];

float out = [myNumber floatValue] + [myNumber floatValue];
[f autorelease];

There is also a floatValue method on NSString so you can also do something like:

在NSString上还有一个floatValue方法，所以你也可以这样做：

float sum = [textField1.text floatValue] + [textField2.text floatValue];

Which is a little more concise.
