您好,提前感谢您的耐心和帮助
这是我正在做的事情:
- 我以编程方式创建多个调用相同功能的按钮
而我想要完成的是:
- 按下按钮后,我希望通用功能运行并禁用所有按钮,以便在执行第一次调用期间不会再次调用该功能。第一次通话结束后,我想重新启用按钮。
这是我创建按钮的方法:
@interface ViewController ()
{
UIButton *button;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
int tagForTheButton = 0;
int yPossition = 0;
int xPossition = 0;
for (int numberOfTheColomn = 0; numberOfTheColomn < 6; numberOfTheColomn++) {
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.adjustsImageWhenHighlighted = NO;
button.frame = CGRectMake(xPossition, yPossition, 64, 64);
button.tag = tagForTheButton;
[button setTitle:title forState:UIControlStateNormal];
[button addTarget:self actionselector(buttonPressed forControlEvents:UIControlEventTouchUpInside];
[self.scroll addSubview:button];
yPossition=yPossition+100;
tagForTheButton++;
}
}
-(void)buttonPressedid)sender{
//This is my attempt to disable the buttons
//previous mistake used 2578
for (int numberForIncrease; numberForIncrease<6; numberForIncrease++) {
if (button.tag == numberForIncrease) {
UIButton *btn = (UIButton*)[self.scroll viewWithTag:numberForIncrease];
btn.enabled=NO;
[btn setUserInteractionEnabled:NO];
}
}
}

您一定是错误地禁用了它。 docs UIButton.enabled 状态:
If the enabled state is NO, the control ignores touch events and
subclasses may draw differently.
通过添加 NSLog() 调用检查是否正在调用 DisableButton ,并完全取消 DisableButton 方法:
dispatch_sync(dispatch_get_main_queue(), ^{
self.view.userInteractionEnabled = NO;
_btn_sync_outlet.enabled = NO;
_btn_sync_outlet.userInteractionEnabled = NO;
});
这可能对你有帮助
