我有这些值
shours
sminutes
sseconds
srecharge
change
来自宣言
int shours;
int sminutes;
int sseconds;
int srecharge;
bool change;
现在我想在这些其他变量中将这些变量传递给另一个UIViewController(MainViewController)
mhours
mminutes
mseconds
mrecharge
mchange
最简单的方法是什么?

在MainViewController
上创建自定义对象属性并将其设置在FlipsideViewController
上,或者由于某种原因无法执行此操作:创建一个对象来保存这些值并将其放入{{1}并阅读NSUserDefaults
。

我只是创建一个“Model”类来保存这些变量并将模型类从一个视图控制器传递给下一个视图控制器。一旦它在view1&中链接view2在从view1转换到view2期间,然后在从view2转换回view1时自动更新。使用@property(assign)int shours,这样就可以创建setter和getter。
使用这种方法,使用segues可以正常工作。您不需要使用NSUserDefaults或NSNotificationCenter。

我会创建一个类来保存这些值。然后在视图控制器之间传递此对象。
这样的事情:

@implementation MyObject
@synthesize shours = _shours;
@synthesize sminutes = _sminutes;
@synthesize sseconds = _sseconds;
@synthesize srecharge = _srecharge;
@synthesize change = _change;
-(id) initWithHours:(int)hours
minutes:(int)minutes
seconds:(int)seconds
recharge:(int)recharge
changed:(BOOL)changed {
if ((self = [super init])) {
_shours = hours;
_sminutes = minutes;
_sseconds = seconds;
_srecharge = recharge;
_change = changed;
}
return self;
}
@end
并像这样实例化你的对象:
MyObject *myObject = [[MyObject alloc] initWithHours:2
minutes:3
seconds:4
recharge:1
changed:NO];
然后将整个对象传递给其他VC。
