项目要求 就自己写了一个弹框 不知道对不对 先记录下来 目前支持 四种样式吧 可以按钮文字 内容的个别文字变色
改变文字颜色的调用方法
SJZAlertViewController *vc = [[SJZAlertViewController alloc] init];
__weak typeof(self) weakSelf = self;
NSString *cardStr = [NSString stringWithFormat:@"确定消耗%@张推荐卡在%@吗？",cardnumStr,cardNameStr];
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext|UIModalPresentationFullScreen;// 这个写里面就好了 不需要这里写
NSMutableArray *rangeArray = [[NSMutableArray alloc] initWithObjects:[NSValue valueWithRange:NSMakeRange(4, cardnumStr.length+1)],[NSValue valueWithRange:NSMakeRange(9+cardnumStr.length, cardNameStr.length+1)], nil];
NSMutableArray *colorArray = [[NSMutableArray alloc] initWithObjects:RGBA(45, 217, 201, 1),RGBA(45, 217, 201, 1), nil];
[vc alerWithButtonConfigurationTitle:@"推荐卡消耗" message:cardStr style:SJZAlertControllerStyleAlert withRange:rangeArray color:colorArray leftButton:@"取消" rightButton:@"确定" success:^{
[weakSelf setcardNetWorking];
} cancel:^{
} orDelete:^{
}];
[[self viewController] presentViewController:vc animated:YES completion:^{
}];
按钮文字变化的
__weak typeof(self) weakSelf = self;
SJZAlertViewController *vc = [[SJZAlertViewController alloc] init];
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext|UIModalPresentationFullScreen;
[vc alerWithButtonConfigurationTitle:@"结束直播" message:@"您正在直播中,确定结束直播并退出吗？" style:SJZAlertControllerStyleDelete withRange:@[] color:@[] leftButton:@"结束直播" rightButton:@"最小化" success:^{
} cancel:^{
[weakSelf closeRoom];
} orDelete:^{
}];
[self presentViewController:vc animated:YES completion:^{
}];
