虽然不是大姿势点，但有时候难免会忘记了，记录一下

NSString *newString = [NSString stringWithFormat:@"%@%@",tempA,tempB];

字符转NSInteger      NSInteger k = [newString integerValue];

NSInteger转字符      NSString *s = [NSString stringWithFormat:@"%ld",k];

字符转int                int intString = [newString intValue];

int转字符                NSString *stringInt = [NSString stringWithFormat:@"%d",intString];

字符转float             float floatString = [newString floatValue];

float转字符            NSString *stringFloat = [NSString stringWithFormat:@"%f",intString];
