这是ViewControllerOne:
- (IBAction)total {
float a = ([textfield1.text floatValue]);
float b = ([textfield2.text floatValue]);
float c = ([textfield3.text floatValue]);
float d = ([textfield4.text floatValue]);
float e = ([textfield5.text floatValue]);
float f = a+b+c+d+e+([textfield6.text floatValue]);
total.text = [[NSString alloc] initWithFormat:@"$%.2f", f];
这是View ControllerTwo:
float g = ([textfield1.text floatValue]);
float h = ([textfield2.text floatValue]);
float i = ([textfield3.text floatValue]);
float j = ([textfield4.text floatValue]);
float k = ([textfield5.text floatValue]);
float l = a+b+c+d+e+([textfield6.text floatValue]);
totalTwo.text = [[NSString alloc] initWithFormat:@"$%.2f", l];
在ViewControllerThree中,我想用ViewControllerTwo的总和从ViewControllerOne中减去总和,并在标签中显示答案。
答案 0 :(得分:0)
存储和total.text
&的值totalTwo.text
中的appDelegate
喜欢
在AppDelegate.h文件中
float totalOne, totalTwo;
@propery(nonatomic)float totalOne, totalTwo;
在AppDelgate.m文件中,
@synthesize totalOne, totalTwo;
- (IBAction)total
{
//Create the instance of appDelegate as
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
float a = ([textfield1.text floatValue]);
float b = ([textfield2.text floatValue]);
float c = ([textfield3.text floatValue]);
float d = ([textfield4.text floatValue]);
float e = ([textfield5.text floatValue]);
float f = a+b+c+d+e+([textfield6.text floatValue]);
app.totalOne = f;
total.text = [[NSString alloc] initWithFormat:@"$%.2f", f];
}
//Create the instance of appDelegate as
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
float g = ([textfield1.text floatValue]);
float h = ([textfield2.text floatValue]);
float i = ([textfield3.text floatValue]);
float j = ([textfield4.text floatValue]);
float k = ([textfield5.text floatValue]);
float l = a+b+c+d+e+([textfield6.text floatValue]);
app.totalTwo = l;
totalTwo.text = [[NSString alloc] initWithFormat:@"$%.2f", l];
-(IBAction)btnCalculate
{
//Create the instance of appDelegate as
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
totalthree = app.totalOne - app.totalTwo;
lbl.text = [NSString StringWithFormat:@"$%.2f", totalThree];
}
