我已經在iphone中做了一個溫度轉換器的應用程序,我希望當它在模擬器啓動時,只有數字鍵盤應該來,而不是阿爾法鍵盤。如何只使用數字鍵盤
#import "farh_celcius_conv_AppDelegate.h"
float i;
float s;
float p;
@implementation farh_celcius_conv_AppDelegate
@synthesize window,display,farhenite,display1;
-(IBAction) convert {
s = ('0','1','2');
if(p == s)
{
NSString *str = farhenite. text;
float n = [str floatValue];
if (n != 0) {
k =.5559* (n-32);
i = 5*(n -32)/9 +273 ;
[display setText:[NSString stringWithFormat:@"%f",k]];
[display1 setText:[NSString stringWithFormat:@"%f",i]];
}
}
}
- (void)dealloc {
[window release];
[super dealloc];
}
@end
