这是一个iOS下拉框控件，提供了丰富的属性自定义UI。同时实现了弹出框的自动防遮挡，以及异步数据的加载功能（比如网络数据的请求）
1.同步数据
FLNiceSpinner *spinner = [[FLNiceSpinner alloc] initWithFrame:CGRectMake(50, 100, 100, 30)];
spinner.delegate = self;
[self.view addSubview:spinner];
实现协议方法
- (NSString *)fl_spinner:(FLNiceSpinner *)spinner showItemStringAtIndex:(NSInteger)index {
if ([spinner isEqual:_spinner1]) {
return _arr1[index];
}
else if ([spinner isEqual:_spinner2]) {
return _arr2[index];
}
else if ([spinner isEqual:_spinner3]) {
return _arr3[index];
}
else if ([spinner isEqual:_spinner4]) {
return _arr4[index];
}
else if ([spinner isEqual:_spinner5]) {
return _arr5[index];
}
else if ([spinner isEqual:_spinner6]) {
return _arr6[index];
}
else if ([spinner isEqual:_spinner7]) {
return _arr7[index];
}
else if ([spinner isEqual:_spinner8]) {
return _arr8[index];
}
else if ([spinner isEqual:_spinner9]) {
return _arr9[index];
}
return nil;
}
- (NSInteger)fl_itemsCountOfSpinner:(FLNiceSpinner *)spinner {
if ([spinner isEqual:_spinner1]) {
return _arr1.count;
}
else if ([spinner isEqual:_spinner2]) {
return _arr2.count;
}
else if ([spinner isEqual:_spinner3]) {
return _arr3.count;
}
else if ([spinner isEqual:_spinner4]) {
return _arr4.count;
}
else if ([spinner isEqual:_spinner5]) {
return _arr5.count;
}
else if ([spinner isEqual:_spinner6]) {
return _arr6.count;
}
else if ([spinner isEqual:_spinner7]) {
return _arr7.count;
}
else if ([spinner isEqual:_spinner8]) {
return _arr8.count;
}
else if ([spinner isEqual:_spinner9]) {
return _arr9.count;
}
return 0;
}
2.异步方法
用于异步数据加载，例如数据需要通过网络加载
FLNiceSpinner *spinner = [[FLNiceSpinner alloc] initWithFrame:CGRectMake(50, 100, 100, 30)];
spinner.delegate = self;
spinner.isAsyncGetData = YES
[self.view addSubview:spinner];
实现代理方法
- (void)fl_spinner:(FLNiceSpinner *)spinner requestDataSuccess:(void (^)(NSArray<NSString *> *))success fail:(void (^)(void))fail {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
success(@[@"中文", @"英文", @"法语", @"德语", @"西班牙语", @"四川话"]);
});
}
