iOS 防止UIButton重复点击

 

使用uibutton的enabled或userinteractionenabled

使用uibutton的enabled属性, 在点击后, 禁止uibutton的交互, 直到完成指定任务之后再将其enabled即可.

[btn addtarget:self action:@selector(nextstop:) forcontrolevents:uicontroleventtouchupinside];

 

- (void)nextstop:(uibutton *)sender {
    sender.enabled = no;
    [self btnclicked];
}

 

- (void)btnclicked {

    dispatch_after(dispatch_time(dispatch_time_now, (int64_t)(1 * nsec_per_sec)), dispatch_get_main_queue(), ^{
    nslog(@"btnclicked");
    btn.enabled = yes;
});
}
