iOS 禁用以编程方式创建的按钮，直到功能完成

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];
        }
    }


}

Best Answer-推荐答案

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;
});
