這聽起來很複雜,但我可以回答任何問題。我嘗試以非常複雜的方式執行的操作是我有兩個視圖,我試圖在我的歡迎屏幕主頁上加載。我想要加載的第一個是PageOne的視圖「text1Title」,所以頁面在awakeFromNib上調用了一個方法。現在,當我點擊下一個按鈕時,它告訴它隱藏下一個按鈕並再次運行第一頁方法,這樣它將使if語句有效並刪除text1View並加載第二頁。問題是,當我再次加載PageOne視圖時,它會創建視圖的兩個實例,removeFromSuperview只會刪除一個視圖。我怎樣才能使這個更簡化,並有這項工作?謝謝。刪除意見,以防止多個實例
@implementation WelcomeScreenMain
NSString *const text1Title = @"WelcomeScreenText1";
NSString *const text1Title2 = @"WelcomeScreenText2";
- (void)awakeFromNib
{
[self PageOne];
}
- (void) PageOne
{
//Page One
WelcomeScreenText1* text1View =
[[WelcomeScreenText1 alloc] initWithNibName:text1Title bundle:nil];
// embed the current view
[myTargetView addSubview: [text1View view]];
// make sure we automatically resize the controller's view to the current window size
[[text1View view] setFrame: [myTargetView bounds]];
if (myButton.isHidden) {
[[text1View view] removeFromSuperview];
[self PageTwo];
}
}
- (void) PageTwo
{
//Page Two
WelcomeScreenText2* text2View =
[[WelcomeScreenText2 alloc] initWithNibName:text1Title2 bundle:nil];
// embed the current view to our host view
[myTargetView addSubview: [text2View view]];
// make sure we automatically resize the controller's view to the current window size
[[text2View view] setFrame: [myTargetView bounds]];
}
-(IBAction)nextButton:(id)sender
{
myButton.hidden = YES;
[self PageOne];
}
