JKAlertManager迭代记录

JKAlertManager用法

UIAlertControllerStyleAlert样式

 JKAlertManager * manager = [[JKAlertManager alloc] initWithPreferredStyle:UIAlertControllerStyleAlert title:<#title#> message:<#nil#>];  [manager configueCancelTitle:<#@"取消"#> destructiveIndex:JKAlertDestructiveIndexNone otherTitles:<#array#>]; [manager showAlertFromController:self actionBlock:^(JKAlertManager *tempAlertManager, NSInteger actionIndex, NSString *actionTitle) { if (actionIndex != tempAlertManager.cancelIndex) { <#doSomething#> } }];

UIAlertControllerStyleAlert类型带TextField

JKAlertManager * manager = [[JKAlertManager alloc]initWithPreferredStyle:UIAlertControllerStyleAlert title:self.dataArray[indexPath.row] message:self.dataArray[indexPath.row] ];[manager configueCancelTitle:@"取消" destructiveIndex:1 otherTitles:@"其他按钮1",@"Destructive按钮",@"其他按钮2", nil];[manager addTextFieldWithPlaceholder:@"请输入账号" secureTextEntry:NO ConfigurationHandler:nil textFieldTextChanged:^(UITextField *textField) {         NSLog(@"1   %@",textField.text);}];[manager addTextFieldWithPlaceholder:@"请输入密码" secureTextEntry:YES ConfigurationHandler:^(UITextField *textField) {        textField.clearsOnBeginEditing = YES;} textFieldTextChanged:^(UITextField *textField) {        NSLog(@"2   %@",textField.text);}];    [manager showAlertFromController:self actionBlock:^(JKAlertManager *tempAlertManager, NSInteger actionIndex, NSString *actionTitle) {         UITextField * userNameTextField = tempAlertManager.textFields[0];         UITextField * passwordTextField = tempAlertManager.textFields[1];    }];

UIAlertControllerStyleActionSheet样式

JKAlertManager * manager = [[JKAlertManager alloc]initWithPreferredStyle:UIAlertControllerStyleActionSheet title:@"title" message:@"massage" ];[manager configueCancelTitle:nil destructiveIndex:0 otherTitles:@"Destructive按钮",@"其他按钮1",@"其他按钮2", nil];[manager configuePopoverControllerForActionSheetStyleWithSourceView:cell sourceRect:cell.bounds popoverArrowDirection:UIPopoverArrowDirectionAny];[manager showAlertFromController:self actionBlock:^(JKAlertManager *tempAlertManager, NSInteger actionIndex, NSString *actionTitle) {       self...}];

JKAlertManager部分代码用意介绍

@interface __JKAlertManagerPrivateHolder : UIView@property (nonatomic, strong) JKAlertManager * alertManager;@end@implementation __JKAlertManagerPrivateHolder@end@interface JKAlertManager ()@property (nonatomic, weak) __JKAlertManagerPrivateHolder * privateHolder;@end

- (void)showAlertFromController:(UIViewController *)controller actionBlock:(JKAlertActionBlock)actionBlock{    if (self.privateHolder) {        [self.privateHolder removeFromSuperview];        self.privateHolder = nil;    }            /// 私有类，强引用JKAlertManager    __JKAlertManagerPrivateHolder * privateHolder = [[__JKAlertManagerPrivateHolder alloc] initWithFrame:CGRectZero];    privateHolder.backgroundColor = [UIColor clearColor];    privateHolder.alertManager = self;    self.privateHolder = privateHolder;    [controller.view addSubview:privateHolder];            [controller presentViewController:self.alertController animated:YES completion:nil];        // 解除Block循环引用，释放内存    __weak typeof(self) weakSelf = self;    self.privateBlock = ^(NSInteger actionIndex, NSString * actionTitle){        __strong typeof(weakSelf) strongSelf = weakSelf;        if (actionBlock) actionBlock(strongSelf, actionIndex, actionTitle);                [[NSNotificationCenter defaultCenter]removeObserver:strongSelf];        strongSelf.alertController = nil;        strongSelf.otherTitles = nil;                /// 主动释放Block，解除循环引用        [strongSelf.privateHolder removeFromSuperview];        strongSelf.textFieldChangedBlockMutDict = nil;        strongSelf.privateBlock = nil;    };}

快速替换掉工程中所有的UIAlertView，换用UIAlertController

基于Runtime+Block封装的UIAlertView和UIActionSheet分类

@property (nonatomic, strong)UIAlertView * alertView;@property (nonatomic, strong)UIActionSheet * actionSheet;

    self.alertView = [[UIAlertView alloc]initWithTitle:@"title" message:@"message" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"其他", nil];    [self.alertView showAlertViewWithActionBlock:^(UIAlertView *newAlertView, NSInteger buttonIndex) {        self...    }];            self.actionSheet = [[UIActionSheet alloc]initWithTitle:@"title" delegate:nil cancelButtonTitle:@"取消" destructiveButtonTitle:@"destructiveButtonTitle" otherButtonTitles:@"otherButtonTitles", nil];    [self.actionSheet showActionSheetInView:self.view completion:^(UIActionSheet *originalActionSheet, NSInteger buttonIndex) {        self...    }];
