您好,并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
我想要完成的事情: - 按下按钮后,我希望运行公共功能并禁用所有按钮,以便在执行第一次呼叫期间不再调用该功能。在第一次通话结束后,我想重新启用按钮。
以下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 action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.scroll addSubview:button];
yPossition=yPossition+100;
tagForTheButton++;
}
}
-(void)buttonPressed:(id)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];
}
}
}

您必须正确禁用它。 UIButton.enabled
状态的docs:
如果启用状态为NO,则控件忽略触摸事件和 子类可能会有不同的描述。
通过添加DisableButton
来电,检查是否正在调用NSLog()
,&amp;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;
});
这可能对您有所帮助:)。

我不明白为什么你需要从0到2577循环以禁用你已经有iVar指向的按钮..?
为什么不直接关闭userInteraction到整个视图(或者如果对于包含所有按钮的containerView不可能)?
[self.view setUserInteractionEnabled: NO ];
或者说,为什么不在那里使用iVar呢?
{
BOOL _ignoreButtons;
}
-(void)buttonPressed:(id)sender{
if (!_ignoreButtons){
_ignoreButtons = YES;
//do your time consuming job, possibly on bg thread
//on completion..
_ignoreButtons = NO;
}
}
