[英]UIButton not working when single tap gesture is added to superview
[英]UIButton not working on the first tap
我在游戲《光學戰斗》中做了一個自定義開關,以打開和關閉聲音效果,但是由於某些原因,在輕按時,將開關移動到另一個位置的動畫按鈕無法使用。 隨后的水龍頭工作,但不是第一個。
在按鈕的IBAction中,我有:
- (IBAction)theSwitch:(id)sender {
NSUserDefaults *toggle = [NSUserDefaults standardUserDefaults];
if (_toggle == 1) {
[UIView animateWithDuration:0.3 animations:^{
audioToggle.frame = CGRectMake(985.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height);
}];
_toggle ++;
[toggle setInteger:_toggle forKey:@"toggleState"];
[toggle synchronize];
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"audioOn"];
}
else {
[UIView animateWithDuration:0.3 animations:^{
audioToggle.frame = CGRectMake(924.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height);
}];
_toggle --;
[toggle setInteger:_toggle forKey:@"toggleState"];
[toggle synchronize];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"audioOn"];
}
}
然后在viewDidLoad中,檢查開關的狀態並對其進行調整以顯示正確的位置(打開或關閉):
- (void)viewDidLoad
{
[super viewDidLoad];
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"audioOn"]) {
[audioToggle setFrame:CGRectMake(924.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height)];
_toggle = 2;
}
else {
[audioToggle setFrame:CGRectMake(985.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height)];
_toggle = 1;
}
編輯:我用它來解決我的問題,在IBAction中的按鈕:
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"audioOn"]) {
[UIView animateWithDuration:0.3 animations:^{
audioToggle.frame = CGRectMake(985.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height);
}];
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"audioOn"];
}
else {
[UIView animateWithDuration:0.3 animations:^{
audioToggle.frame = CGRectMake(924.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height);
}];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"audioOn"];
}
在你的viewDidLoad
if _toggle = 2;
frame = CGRectMake(924.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height)
和
if _toggle = 1;
frame = CGRectMake(985.0f, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height)
但是在您的buttonAction中卻有所不同。 如果buttonAction正確,則在viewDidLoad
互換。
我懷疑Anusha知道了。 但是我也懷疑,如果您選擇了稍有不同的樣式,您自己會很容易找到它。 切換是打開還是關閉,換句話說就是布爾值的完美匹配。 如果您有一個名為swicthedOn的BOOL,則需要檢查是否為(switchedOn),這將大大提高可讀性。
大概是這樣的:
- (IBAction)theSwitch:(id)sender { // Not using the sender for anything (?)
NSUserDefaults *toggle = [NSUserDefaults standardUserDefaults];
BOOL audioOn = NO;
float toggleX = 924.0f;
if (_switchIsOn) {
toggleX = 985.0f;
audioOn = NO; // not strictly necessary but improves readability
}
else {
toggleX = 924.0f; // not strictly necessary but improves readability
audioOn = YES;
}
_switchIsOn = audioOn;
[UIView animateWithDuration:0.3 animations:^{
audioToggle.frame = CGRectMake(toggleX, 59.0f, audioToggle.frame.size.width, audioToggle.frame.size.height);
}];
[toggle setBool:_switchIsOn forKey:@"toggleState"];
[toggle synchronize];
[[NSUserDefaults standardUserDefaults] setBool:audioOn forKey:@"audioOn"]; // Not being synchronized
}
是的,我對其進行了重構(並可能引入了一些新的錯誤)。 對不起,我沒辦法...
