我有一个应用程序不会在 -init 和 -viewWillLayoutSubviews 方法之外设置框架的问题。当一个人点击编辑按钮时应该发生什么是一个隐藏编辑器视图的动画。尽管如此，当我测试它时，什么都没有发生。问题不是来自动画方法，因为 -setFrame 方法因为它 - 不包含在块中 - 也不起作用。
这是代码：
-(id)init {
if (self = [super init]) {
editButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(editButtonTapped)];
doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonTapped)];
editor = [[UIView alloc] init];
[editor setBackgroundColor:[UIColor yellowColor]];
editor.clipsToBounds = YES;
editorIsOpen = YES;
portraitRegularModeEditorRect = CGRectMake(15, 59, 738, 100);
portraitClosedEditorEditorRect = CGRectMake(15, 59, 738, 0);
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
[[self view] addSubview:editor];
[[self view] setBackgroundColor:[UIColor blueColor]];
}
-(void)viewDidAppear:(BOOL)animated {
[self setForRegularMode];
}
-(void)viewWillLayoutSubviews {
UIInterfaceOrientation io = [[UIApplication sharedApplication] statusBarOrientation];
if (io == UIInterfaceOrientationPortrait || io == UIInterfaceOrientationPortraitUpsideDown) {
//portrait
[editor setFrame:portraitRegularModeEditorRect];
} else {
//landscape
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(void)editButtonTapped {
[self setForScenarioLinesEditingMode];
}
-(void)doneButtonTapped {
[self setForRegularMode];
}
-(void)setForRegularMode {
editingMode = CPRegularMode;
if (!editorIsOpen) {
[UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationCurveEaseOut animations:^(void){
[editor setFrame:portraitRegularModeEditorRect];
} completion:^(BOOL finished) {
editorIsOpen = YES;
}];
}
[[self navigationItem] setRightBarButtonItems:[[NSArray alloc] initWithObjects:editButton,nil]];
}
-(void)setForScenarioLinesEditingMode {
editingMode = CPScenarioLinesEditingMode;
if (editorIsOpen) {
[UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationCurveEaseOut animations:^(void){
[editor setFrame:portraitClosedEditorEditorRect];
} completion:^(BOOL finished) {
editorIsOpen = NO;
}];
}
[[self navigationItem] setRightBarButtonItems:[[NSArray alloc] initWithObjects:doneButton,nil]];
}
